Opinion PANELLI, J. This is an automatic appeal (Pen. Code, § 1239, subd. (b)) from a judgment of death imposed under the 1977 death penalty law. (Former § 190 et seq., Stats. 1977, ch. 316, § 5 et seq., pp. 1256-1262.) Defendant was convicted of the first degree murder of Seng “Nancy” Huynh (§ 187) with findings that he was armed with and used a firearm (§§ 12022, subd. (a), 12022.5). Two special circumstance allegations were found to be true: that the murder was committed while defendant was engaged in the commission or attempted commission of (1) a robbery (former § 190.2, subd. (c)(3)(i)) and (2) a kidnapping (id., subd. (c)(3)(h)). For reasons set forth hereafter, we affirm the judgment in its entirety. I. Guilt Phase A. Background Defendant and a codefendant, Donald Gene Bayles, were jointly charged with the murder of Ms. Huynh and with the two special circumstances— robbery and kidnapping. For enhancement purposes it was further alleged that defendant and Bayles were armed with and used a firearm (§§ 12022, subd. (a), 12022.5) in the commission of the murder. Defendant was also charged with, and admitted, two prior robbery convictions. Pretrial motions for change of venue by defendant and Bayles (§ 1033) were denied, as were pretrial motions for severance (§ 1098) by Bayles. Defendant’s motions for severance, made during jury selection and on the first day of trial, were also denied. At the conclusion of the prosecution’s case-in-chief, defendant’s motion for judgment of acquittal (§ 1118.1) on the special circumstance allegations was denied. The jury convicted defendant of first degree murder, found the special circumstance allegations true, and sentenced him to death. The jury found codefendant Bayles guilty of murder in the second degree and found true the enhancement allegation that he had been armed with a firearm. B. FACTS 1. Prosecution Case. Ms. Huynh was last seen alive on September 12, 1978, when she left her home about 3 p.m., driving her automobile, a green Hornet. She was on her way to work in downtown Sacramento. Ms. Huynh worked the evening shift, from 3:45 p.m. to 12 p.m. It was her usual practice to park her car in a lot near her place of work. About 3 p.m. on September 12, 1978, witness Michael O’Brien was sitting in his car alongside the lot where Ms. Huynh usually parked. He noticed two men walk past his car, one on the left side of the car and the other on the right. He later identified the man who passed on the left as codefendant Bayles. After passing O’Brien’s car, Bayles stood near the entrance to the parking lot for about five to ten seconds. Bayles shook his head as if he was in doubt about something and then entered the parking lot, leaving O’Brien’s sight. The other man had walked to the parking lot entrance and instantly turned into the lot and disappeared from view. Although O’Brien was unable to identify the man who accompanied Bayles, O’Brien recalled that he was wearing a short-sleeved shirt. The man was about six feet tall, dark, and weighed about one hundred eighty pounds. He had a slight beard, perhaps a mustache, and fairly short, curly hair. About a minute after Bayles left his sight, O’Brien heard a noise which he described as a “pop.” About 30 seconds later, a green Hornet automobile came out of the lot. O’Brien saw three people in the car. Bayles was on the passenger side. In the middle was an Asian woman whom he identified as an “Oriental girl,” sitting with her head down. The driver was the man who had earlier passed to the right of O’Brien’s car. O’Brien saw the car make a right-hand turn going the wrong way on a one-way street, then turn around. The entire episode, from the time O’Brien first saw the two men until he lost sight of the car, lasted about two minutes. Shortly after noon on the same day, the Department of Health, Division of Vital Statistics, located in downtown Sacramento, had received an unsigned application for a copy of defendant’s birth certificate from a man who had come to the department counter. The certificate was to be mailed to defendant in Pacifica. The employee who waited on the customer could not identify defendant at trial as the person who handed her the application, although his face looked “familiar.” As the jury was informed, defendant refused to comply with a court order to provide a handwriting exemplar. His fingerprints, however, were found on the application. Two days after Ms. Huynh’s disappearance, on the morning of September 14, 1978, her car was found by police officers on Mori’s Point in Pacifica. The car and the area around it were searched and processed for evidence. Bayles’ fingerprints were found on two beer cans discovered in some bushes along the edge of the roadway, on the gas cap of the car, on the cellophane wrapper of an empty package of Camel cigarettes found beneath the driver’s seat, and on a map in the glove box. Defendant’s fingerprints were found on another map in the glove box and on a section of a newspaper found on the front seat of the vehicle. The newspaper was a copy of the Sacramento Bee, Blue Star Edition, dated September 13, 1978. An expended .45 caliber cartridge casing was found between the front seat cushions on the driver’s side of the vehicle. On the floorboard beneath the driver’s seat was a cash register receipt from a market in Hamilton City, California, dated September 13, 1978. On the floor beneath the rear seat of the vehicle was a folded and blood-stained napkin. There were also bloodstains on the rear seat cushion and paper bags with blood on them in the trunk of the vehicle. Laboratory analyses indicated that the blood on the napkin, seat cushion, and paper bags was human blood which came from the same individual. Henry Souza testified that he saw a green Hornet driven out onto Mori’s Point about 6 p.m. the evening before the police found Ms. Huynh’s car. Two Caucasian men were in the car and left within a few minutes after they arrived. The taller, huskier man was driving. Souza could not say whether defendant and Bayles were the two men he saw. David Beverdge testified that in September 1978 he owned and operated the food market in Hamilton City which issued the September 13 receipt found in Ms. Huynh’s car. Hamilton City is located about 11 miles east of Interstate 5 and is about a 2-hour drive north of Sacramento. Beverdge recalled that on September 13 he sold a six-pack of Budweiser beer to two Caucasian males, who also bought a newspaper. Although Beverdge could not recall what kind of paper the men bought, he recalled it cost 15 cents. Included among the 15-cent papers he sold at the time was the Blue Star Edition of the Sacramento Bee. Beverdge waited on the men for about two minutes. They both appeared to be in their early 20’s. One of them was over six feet, taller and heavier than his companion. The taller man also had lighter hair than his companion, and it was he who purchased the beer and gave instructions. Beverdge saw no one else with the two men, and he did not notice the car they were driving. Beverdge could not identify either defendant. On the morning of September 16, 1978, two days after the victim’s car was found in Pacifica, Ms. Huynh’s purse and bra were found on the ground at an interchange area off Interstate 5, about five and one-half miles north of the California-Oregon border. Among the items found in her purse were an empty 12-ounce Budweiser can, a lady’s billfold, and a time card signed by the victim. Bayles’ fingerprints were on the time card. On January 20, 1979, nearly four months after her disappearance, Ms. Huynh’s body was located in a wooded area approximately seven miles south of Elk Creek, California. The location was about a two-and-one-half-hour drive from Sacramento. Officers from the Sacramento Police Department and the Colusa County Sheriff’s office were led to the scene by codefendant Bayles, who had been arrested the preceding day in Coming, California. The victim’s body was found in a clearing behind a log, covered by a 55-gallon drum. The body was in an advanced state of decomposition. The only clothing on the body was a blouse. A pair of slacks were lying across the victim’s lower thighs and a pair of shoes was found two or three inches away. Near the victim’s feet were a towel, pair of panties, sanitary napkin, box of facial tissues, and a match book. Dr. Joseph Masters, ^pathologist, conducted an examination of the body after it was returned to Sacramento. He discovered a .45 caliber copper-coated slug in the victim’s right hip. A hole in the upper portion of the slacks found with the body was consistent with having been made by a .45 caliber bullet. The bullet had entered at the side of the left hip joint, passed through the pelvis, and came to rest on the outer surface of the right hip bone. The path was from left to right, slightly down to up, and very slightly front to back. Because the condition of the skin did not permit a determination of the presence of powder bums, Dr. Masters could make no findings as to the distance from which the shot was fired. The gun could have been right up against the victim when fired. Dr. Masters could not determine whether there had been any kind of injury or abuse to the body following the gunshot wound. He could not determine whether the only other injury identified, a bruise on the victim’s left cheek, was caused before or after the shooting. Dr. Masters determined that the cause of Ms. Huynh’s death was a “bullet wound injury of the pelvis,” but could not determine whether the victim had died within seconds or days of having sustained the injury, or at any point along this continuum. Based on his examination, Dr. Masters concluded that the victim had been dead for more than a month but less than six months. The changes that were present could have occurred over a four-month period beginning September 12, 1978. Dr. Masters did not do any tests for the presence of semen because he felt no tests were possible. Nor did he attempt to draw any blood samples for possible typing, because there was no blood present in the body. No blood or seminal fluid was identified on the slacks, panties or sanitary napkin; because of the deteriorated condition of the material examined, any traces of blood and/or seminal fluid that might have been present could easily have been putrefied and lost. Dennis Ribble, an acquaintance and previous coworker, testified that he saw defendant at the latter’s residence in Pacifica on September 10, 1978, two days before the victim’s disappearance and six days before the police found the victim’s car. Defendant’s residence at the time was about a half-mile to a mile from Mori’s Point, where the victim’s car was found. About a week later, Ribble and his wife again saw defendant, who displayed a .45 caliber automatic handgun. Defendant stated that he had been to Sacramento with the weapon and indicated that he had had the gun when Ribble visited him in Pacifica on September 10th. When Ribble saw defendant on the 10th, defendant had “sort of” long hair and a mustache and, as was common for him, was a little unshaven. When Ribble saw defendant about a week later, defendant’s hair and mustache were trimmed. Defendant indicated that he had made these changes in his appearance because he was “in trouble.” In the latter part of October, defendant sold a .45 automatic handgun to a coworker of nibble’s named S. C. Black. Defendant told Black he had to leave town and needed money to do it. Black received four live rounds of ammunition from defendant along with the gun. Black later fired these rounds, saved the shells, and gave them to Ribble who, in turn, delivered the shells to the prosecuting attorney. Black also gave Ribble the gun he had bought from defendant. Ribble’s wife gave the gun to the Pacifica Police Department. Allan Gilmore, a criminalist, testified that the gun had a safety feature on the handle grip which, unless compressed, would prevent the gun from firing. This safety feature could be compressed by pushing the gun into someone’s body. It took six pounds of pressure to pull the trigger. The gun could not be fired, however, unless the hammer was brought all the way back, which could only be done manually or by operating the slide. Gilmore also examined and performed a number of tests on the .45 caliber slug removed from the victim’s body, the .45 caliber cartridge case found between the front seat cushions of the victim’s car, the .45 automatic handgun turned over by Mrs. Ribble to the Pacifica Police Department, and the .45 caliber cartridge cases turned over by Ribble to the prosecuting attorney. Gilmore’s tests were inconclusive. He could not determine whether the fatal slug came from the cartridge case found in the car, nor whether the slug or the cartridge case had been fired from the .45 automatic handgun in evidence. Nor could he determine whether the cartridge cases turned over by Ribble and the cartridge case found in the car had been fired from the same handgun. Gilmore was only able to conclude that all of the cartridges may at some point have been “worked through” the same weapon. In the latter part of September 1978, William Passe, at whose home in Pacifica defendant had been residing, received a letter from defendant dated September 19, 1978, and bearing a San Francisco postmark. In the letter, defendant stated that he needed the pink slip to his car, his clothes, and his fishing poles in order to get out of the state. The letter indicated that a birth certificate for defendant would be arriving in the mail. On May 3, 1979, defendant was arrested in San Francisco. When arrested, he identified himself to the arresting officers as “Robert Ench” and stated to the woman he was with at the time: “That’s it babe. This is sayonara.” On this state of the evidence, the prosecution rested. 2. Defense Case. Defendant did not take the stand. Codefendant Bayles testified that he and defendant were the two men who drove out of the parking lot with Ms. Huynh on the afternoon of September 12, 1978. Bayles had met defendant that morning at a Sacramento bar. The two went together to another bar, then walked near the Capitol to an office where defendant filled out some papers. Around 2 or 3 p.m., they approached the parking lot from which Ms. Huynh was abducted. They had had no conversation regarding stealing a car or robbing or kidnapping anyone; Bayles had not seen defendant with a gun. Defendant entered the parking lot first and said, “Come on, there’s one over there.” Bayles assumed that defendant, who was then out of Bayles’ sight, was heading for another bar. Bayles then heard a “pop” or “phew” sound. He went through the parking lot and found defendant sitting inside a car, in the driver’s seat, next to an Asian woman. Defendant said, “Come on, get in the car, we got us a ride.” Bayles got into the passenger side of the front seat, thinking that the woman was going to provide them with transportation to another bar. The car initially traveled the wrong way on a one-way street. The central theme of Bayles’ defense was that the abduction and death of the victim, and the taking of her car, were entirely the responsibility of defendant and that Bayles accompanied defendant for fear of his own life. Approximately 30 minutes after leaving the parking lot, defendant told Bayles he had shot the victim. The three traveled north along back roads, using money from the victim’s purse for beer and gas and stopping that evening for approximately 30 minutes to an hour at a rest area outside Yreka. They resumed their travel north, but Bayles could not recall anything about the seven or eight hours between leaving the rest area and arriving at the northernmost part of their trip. After Bayles, at defendant’s direction, threw out the victim’s purse and bra, they turned around and drove along back roads to Hamilton City, where they bought a six-pack of beer and a Sacramento Bee. At some point, Bayles urged defendant to take the victim to a doctor, but defendant refused. While driving from Hamilton City, about 24 hours after leaving the Sacramento parking lot, Bayles first noticed or assumed that the victim, who was then lying in the back seat of the car, was dead. Bayles and defendant disposed of the victim’s body outside of Elk Creek. They then headed for the Bay Area, picking up a hitchhiker near the Golden Gate Bridge and dropping him off in downtown San Francisco. At defendant’s suggestion, they then drove to Mori’s Point, where they left the car. While at Mori’s Point, Bayles broke away from defendant and spent the night in some high grass near a gas station. The next day Bayles made his way back home to Coming. Most of defendant’s defense witnesses sought to rebut the notion that defendant had been Bayles’ companion, based primarily on the lack of a positive identification. In his closing statement to the jury, defense counsel argued that defendant’s involvement was best explained by the possibility that he had been the hitchhiker picked up by Bayles and another man after the victim had been killed and her body abandoned. 3. Verdict. The prosecution’s theory was that Ms. Huynh’s death was concurrently caused by her bullet-wound injury and the subsequent confinement barring access to medical care. Defendant’s conduct was viewed as a single continuous course of conduct, with neither the shooting nor the confinement alone sufficient to cause death. The jury was instructed on two theories of first degree murder—premeditated murder and felony murder based on rape or robbery. The jury found defendant guilty of murder in the first degree and found the robbery and kidnapping special circumstance allegations true as to him. The jury found codefendant Bayles guilty of murder in the second degree and found true the enhancement allegation that he had been armed with a firearm. C. Guilt Phase Issues 1. Change of Venue. Defendant contends the court erred in denying his motions for change of venue based on prejudicial pretrial publicity (§ 1033). A change of venue must be granted when the defendant shows a reasonable likelihood that in the absence of such relief, a fair trial cannot be had. (People v. Harris (1981) 28 Cal.3d 935, 948 [171 Cal.Rptr. 679, 623 P.2d 240].) In considering the denial of a motion for change of venue the reviewing court must make an independent evaluation of five controlling factors: the gravity and nature of the offense, the extent and nature of the publicity, the size and nature of the community, the status of the victim, and the status of the accused. (Martinez v. Superior Court (1981) 29 Cal.3d 574 [174 Cal.Rptr. 701, 629 P.2d 502].) When our review is posttrial, we must also examine the voir dire of prospective and actual jurors to determine if the pretrial publicity did in fact have a prejudicial effect. (Harris, supra, at 949.) In this case the gravity and nature of the charged offense—capital murder—must weigh heavily in our determination. However, the extent and nature of the publicity appears “no different in degree or intensity than the usual reporting of other homicides of the kind involved here.” (Odle v. Superior Court (1982) 32 Cal.3d 932, 939 [187 Cal.Rptr. 455, 654 P.2d 225].) Defendant places particular emphasis on the similarities frequently depicted by the media between this case and the unsolved abduction and murder of one Eva Chu—an Asian woman and state employee who was abducted from a downtown Sacramento parking lot during the middle of an afternoon in April 1979. Although the similarities between these two cases are indeed striking, we do not agree with defendant that the media association and, in one instance, confusion of the two cases were inherently inflammatory or constituted the “persistent linking” which defendant assails so as to affect the community’s determination of defendant’s guilt. Only two prospective jurors confused the cases on voir dire, and they were both excused from the venire panels. We also reject defendant’s assertions that the media reporting of his codefendant’s confession and of defendant’s telephone call to his mother should be considered significant factors in determining whether the pretrial publicity was prejudicial. Although each of the four newspaper articles which stated that Bayles had made a confession also indicated that defendant was a suspect in the case, none indicated that Bayles had implicated defendant. (Cf. People v. Tidwell (1970) 3 Cal.3d 62, 65 [89 Cal.Rptr. 44, 473 P.2d 748].) Additionally, the single reporting of defendant’s statement to his mother, though incriminating, did not constitute a confession (cf. People v. Caldwell (1980) 102 Cal.App.3d 461, 472-474 [162 Cal.Rptr. 397]) and did not explicitly implicate him in the murder of Ms. Huynh (cf. Corona v. Superior Court (1972) 24 Cal.App.3d 872, 879-881 [101 Cal.Rptr. 411]). The smaller the community, the more likely a major crime will be embedded in the public consciousness. (Martinez, supra, 29 Cal.3d at 581.) In 1978, Sacramento County had a population of 738,500, ranking seventh in the state’s 58 counties (Cal. Statistical Abstract (1979) table B-5, p. 11). These figures militate against a change of venue. Defendant characterizes Sacramento as a “company town” of state employees and then seeks to elevate the victim’s prominence in the community by virtue of her state employment. (Cf. Frazier v. Superior Court (1971) 5 Cal.3d 287, 289 [95 Cal.Rptr. 798, 486 P.2d 694].) Those prospective jurors who expressed particular feelings about the victim’s status as a state employee were excused. Moreover, while the victim’s status as a Cambodian refugee, the mother of a young son, and a reliable employee “undoubtedly engendered community sympathy” (Martinez, supra, 29 Cal.3d at 584), there is no indication that these factors resulted in “such pervasive civic involvement in the fate of [the] victim” (Maine v. Superior Court (1968) 68 Cal.2d 375, 385 [66 Cal.Rptr. 724, 438 P.2d 372]) as to affect the fairness of the community’s determination of defendant’s guilt. (Cf. Odle, supra, 32 Cal.3d at pp. 940-941; Maine, supra, at 385.) In considering defendant’s status in the community, the press referred to defendant not as an outsider, but as a former resident of Sacramento County. (Cf. Williams v. Superior Court (1983) 34 Cal.3d 584, 594 [194 Cal.Rptr. 492, 668 P.2d 799].) He was not associated with an organization or group which aroused community hostility. (Cf. Frazier, supra, 5 Cal.3d at 290.) Rather, defendant appears to have been relatively anonymous in the community. (People v. Jurado (1981) 115 Cal.App.3d 470, 488 [171 Cal.Rptr. 509].) Finally, we assess the voir dire of the prospective and actual jurors to determine if the pretrial publicity had any prejudicial effect. Defendant argues that all of the actual jurors had some knowledge of the case. As this court has previously stated, however, “It is not required . . . that the jurors be totally ignorant of the facts and issues involved. . . . It is sufficient if the juror can lay aside his impression or opinion and render a verdict based on the evidence presented in court.’ (Irvin v. Dowd (1961) 366 U.S. 717, 722-723 [6 L.Ed.2d 751, 755-759, 81 S.Ct. 1639.)” (Harris, supra, 28 Cal.3d at 949-950.) Defendant also argues that the trial court erroneously relied on the jurors’ own assurances and self-appraisals of impartiality. Contrary to defendant’s assertions, the nine jurors who indicated the extent or time frame of their recollection about pretrial publicity provided the court with an objective basis for its evaluation of their impartiality. The two jurors who did not indicate when, or to what extent, they had been exposed to such publicity did, however, indicate unequivocally that this exposure would, not affect their impartiality and that they would base their decisions on the evidence presented at trial. Absent an assertion that voir dire was improperly limited, no more is required. (See, e.g., Jurado, supra, 115 Cal.App.3d at 491. Cf. People v. Williams (1981) 29 Cal.3d 392, 402-403 [174 Cal.Rptr. 317, 628 P.2d 869].) Defendant also asserts that the voir dire of Juror Saldana warrants special scrutiny as she was unable to provide the assurance of impartiality expressed by the other jurors. Significantly, neither defendant challenged Ms. Saldana for cause nor exercised a peremptory challenge against her, even though none had been used, individually or jointly, at the time she was examined. (Jurado, supra, 115 Cal.App.3d at 491.) Moreover, where a prospective juror gives conflicting answers to questions relevant to her impartiality, as did Saldana, the trial court’s determination as to her state of mind is binding upon the appellate court. (People v. Fields (1983) 35 Cal.3d 329, 355-356 [197 Cal.Rptr. 803, 673 P.2d 680].) Our examination of the voir dire record shows that no juror had formed a pretrial opinion concerning defendant’s guilt or innocence. It thus appears clear from the record that “the jury was not influenced by any of the pretrial publicity and that defendant was not deprived of a fair and impartial trial by reason thereof.” (People v. Salas (1972) 7 Cal.3d 812, 819 [103 Cal.Rptr. 431, 500 P.2d 7, 58 A.L.R.3d 832].) Accordingly, we conclude that defendant’s motions for change of venue were properly denied. 2. Security Arrangements. Defendant contends that he was denied due process of law and a fair trial by excessive security arrangements without a showing of need for such arrangements. Insofar as defendant’s claim is based on section 688, it is without merit, for that section applies only to physical restraints which, it is conceded, were not imposed in this case. The number of armed, uniformed sheriff’s deputies in the courtroom fluctuated between four and six. Defense counsel objected to the number and/or placement of the deputies several times during jury selection and once during trial. As far as the record shows, when six deputies were present, two were posted near the doorway. On one occasion, it was brought to the court’s attention that while one deputy was positioned behind codefendant Bayles, two were posted behind defendant. The court noted, however, that the placement of the deputies was merely incidental to the configuration of the tables at which they sat. Unless armed guards are present in an unreasonable number, their presence need not be justified by the court or the prosecutor. (People v. Duran (1976) 16 Cal.3d 282, 291, fn. 8 [127 Cal.Rptr. 618, 545 P.2d 1322, 90 A.L.R.3d 1].) Undoubtedly, more than the usual number of guards were present at pretrial proceedings and during trial in this case. However, the court’s remarks when overruling defendant’s objections reflect the court’s implicit decision that the presence of four to six uniformed guards was not unreasonable. From the limited record before us, it appears that the guards were strategically placed in the courtroom and were primarily concerned with security outside the courtroom. Given the nature of the charges, we cannot say that the trial court erred in concluding that the measures taken were not unreasonable. (See Holbrook v. Flynn (1986) 475 U.S. 560 [89 L.Ed.2d 525, 106 S.Ct. 1340]; People v. Miranda (1987) 44 Cal.3d 57, 114-115 [241 Cal.Rptr. 594, 744 P.2d 1127].) 3. Peremptory Challenges. Section 1070.5 prescribes the number and manner of exercising peremptory challenges by jointly tried defendants: “[W]hen two or more defendants are jointly tried for any public offense, whether felony or misdemeanor, the state and the defendants shall be entitled to the number of challenges prescribed by Section 1070, which challenges on the part of the defendants must be exercised jointly. Each defendant shall also be entitled to five additional challenges which may be exercised separately; the state shall also be entitled to additional challenges equal to the number of all the additional separate challenges allowed the defendants.” Defendant contends that the trial court erred in requiring him to agree with codefendant Bayles in the exercise of joint peremptory challenges. He asserts that the requirement of joint challenges creates a disparity between the prosecution and the defense which violates constitutional guaranties of due process and equal protection. The requirement of agreement in the exercise of codefendants’ joint peremptory challenges is supported by the plain language of the statute and all relevant authority. (See People v. McCalla (1857) 8 Cal. 301, 303; People v. King (1966) 240 Cal.App.2d 389, 398-402 [49 Cal.Rptr. 562, 21 A.L.R.3d 706]; People v. Lara (1967) 67 Cal.2d 365, 394-395 [62 Cal.Rptr. 586, 432 P.2d 202]; see also Witkin, Cal. Criminal Procedure (1963) Trial, § 405, p. 406; and Annot. (1968) 21 A.L.R.3d 725, 738-742, and cases cited therein.) Further, we have previously upheld section 1070.5 against due process and equal protection challenges. (See People v. Miranda, supra, 44 Cal.3d at 79-80; People v. Lara, supra, 67 Cal.2d at 394-395; see also People v. King, supra, 240 Cal.App.2d at 398-402.) Neither the state nor federal Constitution “requires that Congress or the California Legislature grant peremptory challenges to the accused or prescribe any particular method of securing to an accused the right to exercise the peremptory challenges granted by the appropriate legislative body.” (People v. King, supra, 240 Cal.App.2d at 399.) In People v. Wheeler (1978) 22 Cal.3d 258 [148 Cal.Rptr. 890, 583 P.2d 748], Justice Mosk reiterated that “the peremptory challenge is not a constitutional necessity but a statutory privilege” limited only, as stated in King, “ ‘by the necessity of having an impartial jury.5” (22 Cal.3d at 281, fn. 28.) In Stilson v. United States (1919) 250 U.S. 583 [63 L.Ed. 1154, 40 P.2d 28], upholding a federal statute which required that the parties on each side be considered a single party for purpose of peremptory challenges, the high court stated: “There is nothing in the Constitution of the United States which requires the Congress to grant peremptory challenges to defendants in criminal cases; trial by an impartial jury is all that is secured. ... It may be, as is said to have been the fact in the trial of the present case, that all defendants may not wish to exercise the right of peremptory challenge as to the same person or persons and that some may wish to challenge those who are unobjectionable to others. But this situation arises from the exercise of a privilege granted by the legislative authority and does not invalidate the law. The privilege must be taken with the limitations placed upon the manner of its exercise.” (250 U.S. at 587-588 [63 L.Ed. at 1156-1157]; italics in original.) Defendant recognizes that all the authorities are contrary to his position but attempts to distinguish the instant case in that it involved a capital defendant with a hostile codefendant with whom he had a conflict of interest and with whom he was unable to cooperate in the exercise of some of the joint challenges. We find this argument unavailing. Defendant and Bayles were allowed 26 joint challenges of which they exercised 20; Bayles exercised 3 of his 5 individual challenges, and defendant exercised all of his individual challenges. The voir dire exhausted two 60-person panels and part of a third; a total of 56 peremptory and 55 for cause challenges were exercised; jury selection took 13 days. As noted, defendant attempts to distinguish this case from what appears to be well-established authority. Although defendant’s characterization of the pretrial situation emphasizes “totally conflicting defenses” and “basic conflict of interests,” it was a fact that each defendant was charged with a capital offense and each pursued a defense of denial. Indeed, conflict and adverse interests amongst codefendants is not unusual. They seldom have common interests: “Frequently, as in the instant case, one defendant attempts to show that he is less, or his codefendant more, blameworthy, in the hope of avoiding the death penalty.” (People v. Floyd (1970) 1 Cal.3d 694, 720 [83 Cal.Rptr. 608, 464 P.2d 64].) Ironically, it is precisely at the time of jury selection that codefendants would seem to have a common interest, namely choosing a jury that is not “pro-prosecution.” Nor is this the first capital case where codefendants have had diverse and conflicting interests. In People v. Turner (1984) 37 Cal.3d 302 [208 Cal.Rptr. 196, 690 P.2d 669], remarkably similar to the instant case in that one defendant testified in his own defense by painting the other defendant as the villain, we stated: “As to conflicting defenses, counsel could articulate no reason for separate trials except to point out that the prosecution would simply put on its case, then sit back and watch as defense counsel became the real adversaries. Of course, if that point has merit, separate trials would appear to be mandatory in almost every case.” (Id. at pp. 312-313.) While Turner concerned the propriety of consolidation for trial, People v. King, supra, 240 Cal.App.2d 389 is directly on point. King too was a capital case. There the stated reason for seeking additional peremptories was the adverse interests of the codefendants, as a result of which, it was urged, they were able to agree on only five of the joint challenges available at that time. (240 Cal.App.2d at 398-399.) Finally, defendant asserts that only he was facing a potential death sentence. He points to a statement made by Bayles’ counsel on the occasion of one refusal to agree with defendant in the exercise of a joint peremptory challenge. Bayles’ counsel noted that he was “not particularly concerned about the death penalty.” However, differing concerns among codefendants about the likelihood of a death verdict does not compel invalidation of section 1070.5. In People v. Lara, supra, 67 Cal.2d 365, we upheld the statute despite its inapplicability to one of the defendants, too young to be subject to that penalty. In Lara we found no statutory authority for additional challenges and also found no abuse of discretion in denying a motion to sever because of the limitations in section 1070.5. In sum, we conclude that the trial court allocated the peremptory challenges in precisely the manner prescribed in section 1070.5. We are not persuaded that defendant’s case is so unique as to compel reexamination of the well-settled law upholding the section against constitutional challenge and are further persuaded that defendant has not shown that he has been denied an impartial jury. 4. Unrepresentative Jury. Defendant contends that the exclusion of prospective jurors because of their opposition to the death penalty denied him a representative jury. This contention has been rejected by us in a number of recent cases (People v. Fields, supra, 35 Cal.3d 329, 374, cert. den. (1984) 469 U.S. 892; People v. Miranda, supra, 44 Cal.3d 57, 78-79; People v. Melton (1988) 44 Cal.3d 713, 732 [244 Cal.Rptr. 867, 750 P.2d 741]) and by the United States Supreme Court in Lockhart v. McCree (1986) 476 U.S. 162 [90 L.Ed.2d 137, 106 S.Ct. 1758]. 5. Evidentiary Issues. (a) Bayles’ Testimony Regarding Rape. Defendant contends that, in admitting Bayles’ testimony suggesting that defendant raped Ms. Huynh, the trial court failed to comply with Evidence Code section 352 which requires an express finding that the probative value of evidence sought to be introduced outweighs its potential prejudicial effect. (People v. Green (1980) 27 Cal.3d 1 [164 Cal.Rptr. 1, 609 P.2d 468].) As noted, Bayles testified in his own defense. He was also cross-examined at length on the events of September 12 and 13, principally concerning the opportunities for escape and his failure to take advantage of them. On cross-examination, Bayles related that he threw the victim’s purse from the car at defendant’s command, but had no explanation of how the victim’s bra got out of the car. Bayles was then asked if he knew how the victim’s bra was removed in the first place. Over objection by defendant’s counsel, Bayles was permitted to testify that, at the rest stop near Yreka several hours before the purse and bra were discarded, defendant joined the victim in the back seat and said, “Okay, you bitch, now is it.” Bayles further testified that he remained in the front seat, did not look to see what was going on in the back seat, and could not be sure that defendant was having intercourse with the victim. He did acknowledge, however, that he had told Detective Reese that Ms. Huynh had been raped by defendant, based on his subsequent observation that her pants and underpants were pulled halfway down. Bayles stated that he was trying to be alert to opportunities for escape, but was “afraid to look” in the back seat to see if defendant’s pants were up or down. When counsel was permitted to record his objections, he stated that the evidence related to uncharged crimes and was irrelevant and, even if relevant, the prejudicial effect substantially outweighed probative value. The trial court overruled the objections, noting that the testimony “has a bearing at least on the witness’ credibility and that the jury may consider whether the witness did or did not have an opportunity to escape at that time, and having such an opportunity, whether he did or did not attempt it.” The Evidence Code section 352 objection was clearly before the court and, we assume, was considered in its ruling. Nevertheless, the court erred in failing to record that it did in fact weigh prejudice against probative value as required by Green, supra, 27 Cal.3d 1. (See also People v. Frank (1985) 38 Cal.3d 711, 731-732 [214 Cal.Rptr. 801, 700 P.2d 415].) On this record, however, we conclude that the error was harmless. (People v. Watson (1956) 46 Cal.2d 818, 836 [299 P.2d 243].) While Bayles’ testimony as to the act of rape was undoubtedly both probative and potentially prejudicial, it was not the only evidence before the jury which pointed to sexual abuse of the victim. There was other properly admitted evidence from which the jury could have inferred that the victim had been sexually assaulted. The jury was aware that the victim’s bra had been found miles from her body and that the body when found was naked from the waist down. Further, the pathologist’s inconclusive findings did not rule out the possibility that a rape occurred. (b) Officer Lowe’s Testimony Regarding Defendant’s Extrajudicial Admission. Called as a witness by codefendant Bayles, Officer Lowe of the Sacramento Sheriff’s Department testified that on November 26, 1979, he heard defendant make the following admission while in a municipal court holding cell; “When I shot her she just squealed a little bit.” Defendant contends that the trial court committed reversible error in admitting Lowe’s testimony over his Evidence Code section 352 objection. The prosecution had proposed to introduce Lowe’s testimony during its case-in-chief. The court at that time rejected a defense argument as to relevance, ruling that the matters recited in support of the argument went to weight rather than admissibility. The court was concerned, however, with giving defendant the opportunity to contact as potential witnesses, those persons who had been in the holding cell with defendant. When it appeared that the trial would be delayed by the search for the witnesses, the prosecutor withdrew his request to have Lowe’s statement admitted. Later, when Officer Lowe was called to the stand by codefendant Bayles, defendant again objected. First, counsel repeated his contention that the prosecution had deprived defendant of access to material witnesses, i.e., the other prisoners in the holding cell. Court and counsel engaged in extensive discussion on this point. Only thereafter did counsel secondarily refer to Evidence Code section 352; “I would submit that the probative value, especially if you don’t have the person with whom Ainsworth was having the conversation before the Court, that the probative value is substantially outweighed by the danger of undue prejudice and would ask the Court to further exclude it on that ground.” After additional discussion on counsel’s unsuccessful efforts to find the witnesses, the court overruled the objection, explaining that everything that reasonably could be done had been done by the court and the prosecutor to afford counsel the opportunity to meet Lowe’s testimony. Defendant does not now question the court’s ruling insofar as it is based on the witness-accessibility challenge. Rather, he complains that the trial court did not exercise its discretion under Evidence Code section 352, specifically that the record fails to reflect that the court engaged in the probative/prejudicial weighing process required by the statute and the rule of Green, supra, 27 Cal.3d 1. As noted, none of the counsel argued the motion to the court. However, the probative value of the statement had been part of the argument on relevance, namely, that the nexus between the statement and the charged crime was questionable. Defendant’s concern with its prejudicial effect, though never clearly articulated, was underscored by the extensive defense efforts to find witnesses who were in the cell with defendant. Thus, the probative/prejudice issue was before the court. The court, however, erred under the rule of Green in failing to articulate its reasoning or to record its implied finding in ruling on the motion. On the record, however, we find any error in this regard to be harmless. Appellate counsel argues that the statement suggested a callousness on defendant’s part that was likely to outrage the jury. In view of the evidence of defendant’s callous and insensitive conduct vis-a-vis the victim in the 24 hours that followed the shooting, the evidence appears only cumulative. The court’s failure to recite for the record its implied finding that probativeness outweighed prejudice did not result in a miscarriage of justice. (Cal. Const., art. VI, § 13; People v. Watson, supra, 46 Cal.2d at 836.) (c) Bayles’ Extrajudicial Statements. Bayles made two extrajudicial statements regarding his role in the murder, one, shortly after his arrest, to Detective Reese of the Sacramento Police and one to Dr. Captane Thompson during a psychiatric interview requested by the prosecution to determine whether Bayles had the capacity to form the requisite mental state for first degree murder. We reject out of hand defendant’s contention that, under People v. Aranda (1965) 63 Cal.2d 518 [47 Cal.Rptr. 353, 407 P.2d 265], the trial court should have excluded those extrajudicial statements which implicated him. In the present case, where Bayles testified and was available for cross-examination, the admission of his extrajudicial statements implicating defendant did not infringe defendant’s constitutional right to confrontation (Bruton v. United States (1968) 391 U.S. 123 [20 L.Ed.2d 476, 88 S.Ct. 1620]) and did not constitute error under Aranda. (See People v. Anderson (1987) 43 Cal.3d 1104, 1118-1129 [240 Cal.Rptr. 585, 742 P.2d 1306].) We nevertheless address, on general principles of evidence, defendant’s challenges to the extrajudicial statements made by Bayles. (1) Bayles’ Statements to Dr. Thompson. Dr. Captane Thompson, a psychiatrist, testified in Bayles’ defense case as to Bayles’ capacity to form the requisite mental states. Defendant contends that Thompson’s opinion testimony violated basic rules governing the scope and permissible subject matter of expert testimony. Specifically, it is urged that the testimony was little more than an opinion that Bayles was telling the truth—a matter not subject to expert opinion and within the province of the jury. The contention is largely unmeritorious. Dr. Thompson based his testimony on discussions with two police investigators who described the crimes for which Bayles was arrested, Bayles’ past history of arrests for public drunkenness, his assistance in locating the victim’s body, and “his way of seeming to ingratiate himself and act in a way that seemed to want to please people and his rather passive style of relating to them.” Dr. Thompson also relied on Bayles’ statement regarding his involvement in the crimes, which was “fully consistent” with what Thompson had been told by law enforcement personnel. Over the hearsay objections of the prosecutor and counsel for defendant, Dr. Thompson testified to the entire content of Bayles’ statement which, in the main, paralleled Bayles’ testimony at trial. Based on this evidence, Dr. Thompson determined that Bayles was an immature and passive individual with a “childlike dependence on other people.” While Bayles had a problem with alcoholism and was suiFering “some impairment” as a result of “borderline intoxication” at the time of the victim’s abduction, he did have the capacity to premeditate and deliberate. Dr. Thompson testified that he found no evidence that Bayles premeditated or deliberated the crimes in the instant case. On cross-examination by the prosecution, Dr. Thompson stated he felt Bayles had been forthright in relating the events to him and was not feigning or trying to cover up anything. Opinion testimony by an expert witness must be based on matter “perceived by or personally known to the witness or made known to him at or before the hearing, whether or not admissible, that is of a type that reasonably may be relied upon by an expert in forming an opinion upon the subject to which his testimony relates . . . .” (Evid. Code, § 801, subd. (b).) An expert should be allowed to testify to all the facts upon which he bases his opinion, including relevant declarations to him. (People v. Brown (1958) 49 Cal.2d 577, 585 [320 P.2d 5].) The statements are admissible not as proof of the facts stated but to enable the expert to explain and the jury to appraise the basis of his opinion. (Id. at 586.) Dr. Thompson’s testimony was relevant to Bayles’ defense of diminished capacity and Bayles’ extrajudicial statement was clearly admissible as relevant to the development of Thompson’s diagnosis of Bayles’ mental state. The doctor’s statement of his own belief that Bayles was not intentionally lying or deceiving him during the psychiatric interview was relevant to the reliability of the doctor’s conclusions. As the People point out, the doctor did not testify that Bayles was in fact telling the truth or that his version of the events was more credible or worthy of belief than that of other witnesses. While this testimony of Thompson may have tended to enhance the credibility of Bayles’ testimony, that was not the purpose of the psychiatric examination or of the doctor’s testimony. Contrast the situation where a psychiatrist is called upon to assess a witness’s ability to testify truthfully, as in cases where the credibility of a complaining witness is called into question. See, for example, People v. Russel (1968) 69 Cal.2d 187 [70 Cal.Rptr. 210, 443 P.2d 794] and Ballard v. Superior Court (1966) 64 Cal.2d 159 [49 Cal.Rptr. 302, 410 P.2d 838, 18 A.L.R.3d 1416], cited by defendant in support of his challenge here. We agree that, in such cases, where the sole purpose of the psychiatric examination and testimony relates to the credibility of a witness, the psychiatrist may not testify to the ultimate question of whether the witness is telling the truth on a particular occasion. As defendant concedes, that was not the purpose of Thompson’s testimony. We do agree that the admission into evidence of Thompson’s testimony that he “found no evidence that [Bayles] had ... in any way intended . . . to do wrong in this whole episode” or that “he planned or considered the alternatives or reflects on the consequences of his actions in any way” was problematic. A psychiatric opinion that a person lacks the capacity to plan, consider alternatives, or reflect on consequences is of course considered to be within professional expertise, but having concluded that the examinee did have such capacity, we are dubious that an opinion as to whether the examinee in fact did those things is a matter within professional expertise. We are inclined to believe that the question, as phrased, was improper. However, even assuming that the doctor’s response should have been disallowed, this testimony was only a small part of the lengthy testimony of Dr. Thompson and, in the main, his testimony was properly admitted. This small, short portion of the testimony cannot by itself be deemed prejudicial or warrant reversal. (2) Bayles’ Statement to Detective Reese. Detective Reese was called to testify in Bayles’ defense. He related portions of a statement made to him by Bayles shortly after Bayles’ arrest. Defendant contends that the trial court erred in admitting the statement. We conclude that, on this record, any error in permitting Reese to testify to statements made to him by Bayles was harmless. The extrajudicial statement to Detective Reese had been mentioned initially during Bayles’ direct examination when his counsel refreshed Bayles’ recollection from a transcribed version. The prosecutor used portions of the extrajudicial statement to impeach Bayles (Evid. Code, §§ 770 and 780, subd. (h); § 1235) and, on redirect, over defendant’s hearsay objection, Bayles’ counsel sought to rehabilitate Bayles’ credibility with testimony of several prior consistent statements he had made to Detective. Reese. The court overruled the objection on Evidence Code section 791 grounds. Detective Reese was thereafter called to the stand by Bayles and related details of Bayles’ statement to him. The prosecutor vigorously objected to the testimony of Reese as improperly admitted hearsay, noting that Reese was merely repeating Bayles’ entire statement. Defendant joined in the objection. Subdivision (a) of Evidence Code section 791 appears to have no application to the facts here; it only makes admissible evidence of a witness’s prior consistent statement which was made before the witness’s alleged inconsistent statement. In the instant case, Bayles’ testimony was impeached by prior inconsistent statements he had made to Reese. The prior consistent statements admitted to rehabilitate his credibility were made at the same time as the prior inconsistent statements. It is impossible to ascertain whether these prior consistent statements preceded the inconsistent statements, as we are not provided a transcript of Bayles’ entire statement to Reese. Our analysis therefore focuses on subdivision (b). Evidence Code section 791, subdivision (b) makes admissible evidence of a witness’s prior consistent statements to rebut “[a]n express or implied charge . . . that his testimony at the hearing is recently fabricated or is influenced by bias or other improper motive.” The party seeking to introduce a prior consistent statement must show that “the statement was made before the bias, motive for fabrication, or other improper motive is alleged to have arisen.” (Italics added.) That there may always have been present a motive to fabricate does not deprive a party of his right to show that another motive, suggested by the evidence, did not also affect his testimony. (People v. Cannady (1972) 8 Cal.3d 379, 388 [105 Cal.Rptr. 129, 503 P.2d 585].) While defendant concedes that the cross-examination of Bayles by the prosecutor and counsel for defendant was intended to suggest that Bayles’ testimony was fabricated and/or influenced by an improper motive, he argues that such motive arose during the four months between the crime and Bayles’ arrest. Thus, the differences between Bayles’ testimony and his statement to Reese merely evidenced “further refinements” of the same motive that prompted Bayles’ extrajudicial statement, that is, to place the major blame on defendant. As such, defendant submits, Bayles’ statement to Reese was not admissible as a prior consistent statement because it was not made before the improper testimonial motive arose. The People, on the other hand, assert that, while Bayles may have fabricated his story prior to his arrest, a new or additional improper testimonial motive arose after Bayles’ arrest and statement to Reese. The People argue that the thrust of the prosecution’s cross-examination was to imply that “whatever story Bayles had earlier concocted,” Bayles’ trial testimony had been altered from his pretrial statements “to explain away various legal ‘complications’ unwittingly invoked by the extrajudicial versions, such as the felony-murder rule, the law of aiding and abetting, and the several factual inconsistencies between the earlier statements and a duress or lack of knowledge and intent defense.” The People’s position is supported by the prosecutor’s closing argument, which reveals an explicit charge that Bayles fabricated some of his trial testimony after giving his statement to Reese, and an implied charge that Bayles’ motive for fabrication was a recently acquired awareness and understanding of the legal nuances of the charges against him. The People’s position is not, however, supported by the prosecutor’s cross-examination, which was primarily directed at impeaching Bayles’ credibility through the admission of his prior inconsistent statements to Reese. Since the critical time for determining the admissibility of a witness’s prior consistent statements is when such statements are sought to be admitted, not at the closing argument, we are presented with the issue whether impeachment by evidence of prior inconsistent statements may be sufficient to constitute an implied charge of recent fabrication or improper testimonial motive for purposes of Evidence Code section 791. We believe the answer to that question is found in the following comment to that section: “[RJecent cases indicate that the offering of a prior inconsistent statement necessarily is an implied charge that the witness had fabricated his testimony since the time the inconsistent statement was made . ...” 7 Cal. Law Revision Com. Rep. (Dec. 1965) pp. 145-146, citing People v. Bias (1959) 170 Cal.App.2d 502 [339 P.2d 204].) While the Law Revision Commission made the comment with respect to subdivision (a), we conclude that it is equally applicable in interpreting subdivision (b). Based on this minimal but persuasive authority, Bayles’ entire pretrial statement to Reese, which was consistent with his trial testimony, whether testified to by Bayles or Reese, was properly admitted under Evidence Code section 791, subdivision (b) as relevant to rebutting the prosecution’s implied charge of recent fabrication. 6. Sufficiency of Evidence. Defendant contends that the evidence is insufficient to support the conviction of first degree murder based on the theories of premeditation and deliberation of rape-felony-murder and that the judgment must be reversed because we cannot determine whether the jury based its verdict on those theories. (People v. Green, supra, 27 Cal.3d 1; People v. Anderson (1965) 63 Cal.2d 351 [46 Cal.Rptr. 763, 406 P.2d 43].) Defendant concedes the evidence is sufficient to sustain a robbery-felony-murder verdict—“the evidence presented would have supported a finding that the firing of the shot was preceded or accompanied by an intent to rob.” Moreover, we are able to determine from the record—specifically, the jury’s finding of a robbery special circumstance—that the jurors agreed on that theory at least in reaching their verdict. We therefore uphold the first degree murder conviction on the theory of felony murder in perpetration of a robbery. Defendant contends, however, that we cannot uphold the conviction on any felony-murder theory because some of the jurors may have predicated their finding of felony murder on conduct subsequent to the shooting, i.e., deprivation of medical care, which conduct was insufficient to establish a proximate cause of death. The argument is specious. Whichever way the jury may have weighted the concurrent causes of death, no reasonable juror could have concluded on this record that the deprivation of medical care was a cause of death without first concluding that the shooting was a causal factor in the death of Ms. Huynh. Under the felony-murder rule, “the evidence must establish that the defendant harbored the felonious intent either prior to or during the commission of the acts which resulted in the victim’s death . . . .” (People v. Anderson (1968) 70 Cal.2d 15, 34 [73 Cal.Rptr. 550, 447 P.2d 942].) First degree felony murder does not require proof of a strict causal relation between the felony and the homicide, and the homicide is committed in the perpetration of the felony if the killing and the felony are parts of one continuous transaction. (People v. Whitehorn (1963) 60 Cal.2d 256, 264 [32 Cal.Rptr. 199, 383 P.2d 783]; People v. Mason (1960) 54 Cal.2d 164, 168-169 [4 Cal.Rptr. 841, 351 P.2d 1025].) Here, the robbery and the actions causing death were part of one continuous transaction. The record points unerringly to a causal connection between the robbery and the death of the victim. It clearly shows that at least the intent to steal the victim’s automobile was harbored both prior to and during the acts which resulted in the victim’s death; the inference is clear that defendant harbored the requisite felonious intent to steal when he fired the shot that eventually killed the victim; this felonious intent continued for hours as defendant and Bayles fled north. There was ample evidence to support the jury’s finding that the death occurred in the perpetration of the robbery. 7. Instructional Error. Defendant assigns a number of instructional errors: (a) Proximate Cause—CALJIC No. 8.55. Defendant urges that, if the evidence of proximate cause is sufficient, the trial court nevertheless erred in failing to instruct the jury that a finding of proximate cause requires proof that the conduct in question produced a significant decrease in the span of the victim’s life. People v. Phillips (1966) 64 Cal.2d 574, 579 [51 Cal.Rptr. 225, 414 P.2d 353], which defendant cites as authority, is inapposite. In Phillips, a doctor was charged with homicide for convincing the parents of a young cancer victim not to have their daughter’s cancer removed surgically. We held that the doctor’s conduct was the proximate cause of death if it significantly shortened the victim’s life span. Here, there was no issue of intervening and/or superseding causes independent of defendant’s conduct. Defendant shot Ms. Huyhn, which proved fatal because of his further conduct in confining her without medical aid. Since it was defendant’s conduct which set in motion both concurrent causes of death, the Phillips case is inapposite. The jury was given the standard instruction on proximate cause (CALJIC No. 8.55). While defendant could have requested the Phillips, or any other clarifying, instruction (People v. Rogers (1981) 124 Cal.App.3d 1071, 1080 [177 Cal.Rptr. 747]), the court was not compelled to give it sua sponte where, as here, it is clear that defendant’s conduct significantly shortened the life of his 30-year-old victim. (b) Unanimous Agreement—CALJIC No. 17.01. The jury was instructed in the language of CALJIC No. 17.01 that “The defendant is charged with the offense of murder. He may be found guilty of that crime or any lesser included crime if the proof shows beyond a reasonable doubt that he committed any one or more of such acts, but in order to find the defendant guilty, all the jurors must agree that he committed the same act or acts. It is not necessary that the particular act or acts committed so agreed upon be stated in the verdict.” The instruction was inadequate, it is claimed, because it failed to inform the jury that it had to unanimously agree which conduct, the shooting or the barring of access to medical care, constituted th
