Opinion LUCAS, C. J. Ronald Lee Sanders was convicted of first degree murder, attempted murder, robbery, burglary, and attempted robbery. Two allegations that he was armed with a firearm were found true. The jury also found true four special circumstance allegations: the murder was committed while defendant was engaged in the commission or the attempted commission of the robbery and burglary (Pen. Code, § 190.2, subd. (a)(17)(i) & (vii)); the victim was intentionally killed to prevent her testimony in a criminal proceeding (§ 190.2, subd. (a)(10)); and the murder was especially heinous, atrocious and cruel (§ 190.2, subd. (a)(14)). After the penalty phase of the trial, the jury set the penalty at death. This appeal is automatic. (§ 1239, subd. (b).) For the reasons stated below, we set aside the special circumstance findings based on the commission of a burglary and on the jury’s conclusion that the murder was heinous, atrocious and cruel, but otherwise affirm the judgment in its entirety. I. Facts Guilt Phase In 1981, Dale Boender and Janice Allen moved to Bakersfield from Oildale. Boender supported the couple by selling cocaine and marijuana. One of his customers was Brenda Maxwell, but he stopped selling to her because she owed him money from prior transactions. On the morning of January 21, 1981, Maxwell’s aunt, Donna Thompson, and defendant Ronald Lee Sanders visited Maxwell. The three decided to rob Boender of drugs and money and agreed to the following plan: Maxwell would entice Boender to her home by claiming she had a friend who wanted to buy a large quantity of cocaine. When Boender arrived, defendant would knock him out and they would rob him. Defendant would then bind Boender with duct tape before leaving. According to their plan, defendant would similarly bind Maxwell so she would appear to also have been a victim. Thompson would arrive later to “discover” and free the pair. Maxwell’s friend, Glen Blackford, was also visiting her at the time but was left in the living room while Maxwell, Thompson, and defendant planned the crime in the bedroom. When they returned to the living room after their planning session, Maxwell told Blackford “[sjomething is going to happen [so] get out of here.” Blackford and Thompson then left (as planned) and Maxwell placed several calls to Boender to arrange the deal. Enticed by the promise of a large cocaine sale, Boender and Allen drove to Maxwell’s mobilehome. Allen entered the home and began to sit down next to Maxwell. As Boender stepped through the doorway, defendant emerged from the kitchen and began beating Boender with a two-foot long piece of a pool stick. A struggle ensued but Boender and Allen eventually managed to exit the mobilehome, at which point defendant fled. Boender and Allen then drove off, first to a friend’s house but later to a hospital to attend to Boender’s injuries. They stayed at a relative’s home until Friday, January 23, 1981. Meanwhile, Thompson and defendant returned to Maxwell’s mobilehome to discuss the aftermath of the botched robbery attempt. Maxwell was concerned that Boender would realize she had “set him up,” and defendant was worried Boender could identify him. The three drove to a house on Jefferson Street where defendant engaged the assistance of John Cebreros. The group then went to Thompson’s house where Maxwell called mutual friends of hers and Boender’s to tell them she had been robbed and raped so as to enhance her claim that she had been victimized along with Boender. On Friday, Boender and Allen decided to return to Boender’s apartment. They arrived in the afternoon and told Boender’s two roommates, Haney and Weinman, about the earlier assault. Later, Boender and Allen met Boender’s former roommate, George Littleton, at a bar; the three of them went to Littleton’s apartment around 7 p.m. and shared a small bottle of wine. After shopping for groceries, Boender and Allen returned home. Haney and Weinman were gone for the evening. While Boender and Allen were preparing dinner, there was a knock at the door. Leaving Allen in the kitchen, Boender went to the front door and opened it, finding Cebreros and defendant standing there, the latter armed with a gun. Although he believed he had only seconds to live, Boender concentrated on their faces so he could remember them if he should see them again. Defendant spun Boender around and pushed him to the floor, face down. He felt someone’s knee in his back and something pressed against his neck. Allen emerged from the kitchen and was also made to lie on the floor. Boender’s glasses were ripped from his face and both he and Allen were bound and blindfolded. One of the assailants demanded that Boender tell them where he kept his cocaine, and he directed them to Allen’s purse. After he told them his money was in his shirt pocket, someone removed it. Boender heard the two assailants rummaging through the apartment but could not tell what was going on. After a few minutes, he was dragged to what seemed like his bedroom. He heard more footsteps, muffled talking, and more banging around the apartment. One of the assailants said he wanted to leave but the other said he wanted to stay. Boender then heard someone approach, felt a blow to the head, and recalled nothing further. Boender’s roommates returned to the apartment in the early morning and discovered the apartment full of smoke. A search revealed food burning in the oven. On further investigation, they discovered Boender in his bedroom, lying in a pool of blood. After calling an ambulance, they noticed that the apartment was in disarray, there were spots of blood around, and a baggie of marijuana was missing. When Haney found Allen’s body in his bedroom, he called the police. Both Boender and Allen had been bound by lengths of electrical cord cut from Boender’s vacuum cleaner. Allen sustained a fatal head wound which fractured her skull and lacerated her brain. Boender suffered a skull fracture but was conscious and semicoherent when police arrived. He was not questioned until the next day. Haney and Weinman told police about Boender’s story of the attempted robbery two days earlier, prompting police to contact Maxwell. She falsely told police that Cebreros came to her home, forced her to call Boender, and then beat him up when he arrived. However, she gave them accurate descriptions of defendant and Cebreros as well as the address of the Jefferson Street house where defendant met Cebreros. From his hospital bed, Boender gave descriptions of defendant and Cebreros that matched Maxwell’s descriptions. Cebreros was arrested the next day in front of the Jefferson Street house. In his car, police found a gun similar to that which Boender described as the one used in the attempt to murder him. In Cebreros’s boot, police found a baggie of marijuana which was identical to the one taken in the robbery. Both Maxwell and Boender positively identified Cebreros as one of the assailants. A few days later, Maxwell recanted her story and told police the truth about the bungled robbery attempt. She also told police about the duct tape defendant intended to use to bind Boender. Police found a roll of such tape in Maxwell’s home and tests revealed defendant’s fingerprints on it. He was arrested and positively identified by Boender in a photographic lineup later that week. Defendant and Cebreros were tried jointly and they presented an alibi defense. Three defense witnesses testified that on the night of the murder, both defendant and Cebreros were at the home of Cebreros’s brother, Salvador, talking, playing chess, and drinking beer. There was also evidence from Boender’s neighbors that although two men were seen outside Boender’s apartment on the night of the murder, neither one looked like Cebreros or defendant. Finally, there was evidence that defendant had used Maxwell’s roll of duct tape for an innocent purpose a few days earlier. Defendant’s first trial ended in a mistrial when the jury could not reach a verdict. On retrial, both he and Cebreros were convicted on all counts. The prosecutor declined to seek the death penalty against Cebreros and he was sentenced to life without the possibility of parole. Penalty Phase The prosecution produced several witnesses at the penalty phase who described five armed robberies defendant committed in Orange County in 1970. Although none of the witnesses could positively identify defendant at trial, a police expert testified that the fingerprints of the gunman in the five Orange County robberies matched defendant’s fingerprints. James Quinn testified that on October 1, 1970, he was working late at the Allstate Motel in Santa Ana when defendant and a crime partner robbed him at gunpoint. Thomas Ferguson testified that defendant, brandishing a revolver, robbed him on September 12, 1970, while Ferguson was employed as a clerk at the Station Liquor Store in Tustin. Defendant committed an armed robbery in the same establishment on November 20, 1970, this time robbing clerk Fred Turnbull. Sammy Mitchell testified that he was working in Mitchell’s Market in Tustin on October 6, 1970, when defendant robbed him at gunpoint. Defendant was finally arrested after this crime spree while fleeing from yet another armed robbery, this one occurring in a 7-Eleven convenience store, also in Tustin. Defendant confessed his guilt to all five robberies and the police officers to whom he confessed testified at the penalty phase. Defendant was sentenced to state prison and was granted parole in 1973. Defendant declined to present any evidence in mitigation or make a closing argument. The jury returned a verdict of death within a few hours. II. Discussion A. Jury Selection Issues 1. Systematic Underrepresentation in the Jury Pool Before trial, defendant moved to quash the petit jury, arguing that the manner in which Kern County assembled its master jury list violated his right to an impartial jury drawn from a fair cross-section of the community. In support, he presented evidence that he claimed demonstrated a prima facie case that Hispanics were systematically underrepresented in the jury pool. The trial court denied the motion, and defendant now renews the contention. a. The Evidence Supporting the Motion to Quash At the time of defendant’s trial, Kern County assembled its master jury list by randomly drawing names from the county’s voter registration list. Questionnaires were then sent to those chosen to determine eligibility to serve as jurors. There was no attempt to ensure that the ethnic composition of the group selected for jury service approximated that of the county as a whole. Although there were plans in the future to use names of those holding driver’s licenses to supplement those names from the voter registration lists when assembling the master jury list, such plans had not yet been implemented at the time defendant was tried. The parties stipulated that defendant could rely, in support of his motion to quash, on the expert testimony presented in three other recent Kern County Superior Court cases. (See People v. Cantu, Nos. 21891, 22229 (Cantu); People v. Robinson, No. 21518 (Robinson); People v. Streeter, Nos. 22346, 22056, 21910, 21368 (Streeter).) Dr. Newell, an expert in psychology and statistics, testified in the Cantu and Robinson cases (and his testimony was admitted in the Streeter case). He stated that he had scrutinized the available data from the 1980 census and had analyzed jury panels in Kern County between October 1980 and February 1981, as well as panels in May 1981. In Cantu, he testified that the government census reported that Kern County was 21.59 percent Hispanic, and estimated that 17.76 percent of the county was both Hispanic and at least 18 years old, i.e., presumptively jury eligible. To determine the ethnic makeup of the group summoned for jury duty during the period in question, Dr. Newell scrutinized the master jury list, presumably noting those with Spanish surnames. He also conducted telephone surveys to confirm the number of those on the list who were Hispanic. He concluded that 8.3 percent of those appearing for jury duty were Hispanic. In the Robinson case a few months later, Dr. Newell presented even more refined statistics. From the Immigration and Naturalization Service, he obtained the information that 14,387 Hispanic resident aliens resided in Kern County in 1978. (Such evidence was not available for 1980.) Deducting that number from the total number of Hispanics in the county (based on 1980 census figures), Dr. Newell opined that 19.81 percent of Kern County residents were Hispanic. Using the same methodology as in the Cantu case (see fn. 3, ante), he estimated that 16.3 percent of the county was made up of adult Hispanics. He reiterated that 8.3 percent of those appearing for jury duty were Hispanic. He concluded that the likelihood the exhibited disparity would occur by chance was one in one million. After reading the transcripts of the Cantu, Robinson, and Streeter cases and hearing argument on the issue, the trial court denied without prejudice defendant’s motion to quash, stating, “I do believe that there has been a prima facie showing that there is a disproportionate number of people with Hispanic surnames called for jurors, but I am not sure that that means a thing, and everybody knows by reading the Los Angeles Times and any other publication that there are an enormous number of people in this country illegally or green card-wise [s/c] who are not even citizens. fl[] So, I don’t think that really in and of itself means anything.” Defendant renewed the motion later and it was again denied. b. The Fair Cross-section Principle “In California, the right to trial by jury drawn from a representative cross-section of the community is guaranteed equally and independently by the Sixth Amendment to the federal Constitution (Taylor v. Louisiana (1975) 419 U.S. 522, 530 [42 L.Ed.2d 690, 698, 955 S.Ct. 692]) and by article I, section 16 of the California Constitution. (People v. Wheeler (1978) 22 Cal.3d 258, 272 [148 Cal.Rptr. 890, 583 P.2d 748].)” (Williams v. Superior Court (1989) 49 Cal.3d 736, 740 [263 Cal.Rptr. 503, 781 P.2d 537].) “In order to establish a prima facie violation of the fair-cross-section requirement, the defendant must show (1) that the group alleged to be excluded is a ‘distinctive’ group in the community; (2) that the representation of this group in venires from which juries are selected is not fair and reasonable in relation to the number of such persons in the community; and (3) that this underrepresentation is due to systematic exclusion of the group in the jury selection process.” (Duren v. Missouri (1979) 439 U.S. 357, 364 [58 L.Ed.2d 579, 99 S.Ct. 664]; see also Bell, supra, 49 Cal.3d at p. 525; People v. Morales (1989) 48 Cal.3d 527, 543 [257 Cal.Rptr. 64, 770 P.2d 244].) If a defendant demonstrates a prima facie case of systematic underrepresentation under this tripartite test, the burden shifts “to the state to come forward with either a more precise statistical showing that no constitutionally significant disparity existed or that there was a compelling justification for the procedure which results in the disparity in the jury pool.” (Harris, supra, 36 Cal.3d at p. 50.) c. Application The first prong of the Duren test is clearly satisfied; Hispanics, or those with Spanish surnames, constitute a distinctive group for purposes of a fair cross-section analysis. (Morales, supra, 48 Cal.3d at p. 543.) The second prong may be satisfied by showing “that the number of members of the cognizable group is not fair and reasonable in relation to the number of members in the relevant community.” (Bell, supra, 49 Cal.3d at p. 526.) Working from defendant’s most refined statistics, adult Hispanic citizens made up 16.3 percent of Kern County, whereas only 8.3 percent of those appearing for jury duty were Hispanic. Thus, there was an 8 percent absolute disparity and a 49 percent comparative disparity. We have previously noted that “the [United States] Supreme Court has not yet spoken definitively on either the means by which disparity may be measured or the constitutional limit of permissible disparity.” (Bell, supra, 49 Cal.3d at pp. 527-528, fns. omitted.) As in Bell, however, we need not resolve this difficult line-drawing question because defendant fails to establish a prima facie case under Duren’s third prong by showing the disparity is caused by “systematic” exclusion of Hispanics from Kern County juries. By basing his motion to quash on the expert statistical evidence given in the Cantu, Robinson, and Streeter cases, defendant sought to show a statistical disparity occurred over time and was thus the result of a “systematic exclusion” of Hispanics. As we recently explained in Bell, supra, however, such a showing is insufficient, standing alone, to make out a prima facie case of a Sixth Amendment violation. When, as here, “a county’s jury selection criteria are neutral with respect to race, ethnicity, sex, and religion, more is required to shift the burden to the People. The defendant must identify some aspect of the manner in which those criteria are being applied that is: (1) the probable cause of the disparity, and (2) constitutionally impermissible.” (Bell, supra, 49 Cal.3d at p. 524.) Evidence that “race/class neutral jury selection processes may nonetheless operate to permit the de facto exclusion of a higher percentage of a particular class of jurors than would result from a random draw” is insufficient to make out a prima facie case. (Morales, supra, 48 Cal.3d at p. 546, italics in original.) Defendant claims he has satisfied this requirement in Bell (supra, 49 Cal.3d 502) by relying not only on the statistical disparity, but on the fact that at the time of defendant’s trial, Kern County assembled its master jury list solely from the voter registration list. Not only does he argue this is the “probable source” of the disparity, he contends the practice is “constitutionally impermissible,” citing People v. Harris, supra, 36 Cal.3d 36. Our concern here is with the latter requirement: because the county’s juror selection procedures were facially neutral, has defendant shown that procedure is nevertheless “constitutionally impermissible” within the meaning of Belli There is some language in the lead opinion in Harris suggesting that sole reliance on voter registration lists in assembling the master jury list is constitutionally prohibited. We do not, however, read Harris so broadly. In that divided opinion, a three-justice plurality held the defendant made a prima facie showing of a fair cross-section violation based on a statistical showing of racial disparity and the fact that the county assembled its master jury list using only voter registration lists. (36 Cal.3d at p. 58 [plur. opn. by Broussard, J., joined by Bird, C. J., & Reynoso, J.].) Although the trial court did not find the defendant made a prima facie case—and thus the People were never asked to present any rebuttal evidence—the plurality reversed the judgment. Three other justices dissented on this point. (Id. at pp. 72 [dis. opn. by Mosk, J., joined by Richardson, J.], 75 [dis. opn. by Kaus, J.].) In a pivotal separate opinion, Justice Grodin provided a reluctant fourth vote to reverse. He expressly agreed with the plurality that defendant made a prima facie case, despite relying on total population statistics. Justice Grodin further stated that “in light of published studies which point to the exclusive reliance upon voter registration lists as a likely source of racial and ethnic disparity in the composition of juries, I am prepared to say that defendant’s showing should be regarded as sufficient to trigger further inquiry.” (Harris, supra, 36 Cal.3d at p. 71 [cone. opn. by Grodin, J.].) Significantly, he further explained that he “would not reverse the judgment on that account.” (Harris, supra, 36 Cal.3d at p. 71, italics added.) Because the People had no occasion to present rebuttal evidence, he opined the case should be remanded to allow them to do so. (Id. at pp. 71-72.) “Upon full consideration of the relevant evidence it might be concluded that ‘no disparity of constitutional significance exists,’ or that ‘even with the use of multiple sources and all other practical means, a certain level of disparity is unavoidable,’ or that the underrepresentation which does exist is justified by a showing of overriding state interest.” (Id. at p. 72, quoting plur. opn. at p. 59.) Justice Grodin then explained that although he preferred the remand option, there would be no disposition of the case were he to insist on that alternative. Finding this an “intolerable” result, and concluding that he “fundamentally” disagreed with the dissenting opinions, he reluctantly joined the plurality opinion’s disposition to reverse. (Ibid.) As is clear, Justice Grodin did not join the Harris plurality’s far-reaching conclusion that sole reliance on voter registration lists was itself constitutionally prohibited. Indeed, he twice stated his position that identification of that fact, coupled with an adequate statistical showing of racial disparity, merely established a prima facie case of a constitutional violation, and should not itself require reversal. Since Harris, supra, 36 Cal.3d 36, however, this court has refined the procedure by which a criminal defendant can establish a prima facie case of a fair cross-section violation. Unlike in Harris, a defendant attacking facially neutral procedures as the “probable cause” of the statistical disparity must now demonstrate that such procedures are either “constitutionally impermissible” or are being implemented in a constitutionally objectionable manner. (Bell, supra, 49 Cal.3d at p. 524.) As explained above, Harris does not constitute controlling authority for this latter point. Resort to other authority is similarly unhelpful to defendant’s position. We begin our analysis by noting that, at the time of defendant’s trial, our state Legislature permitted sole reliance on voter registration lists to assemble the master jury list. As explained below, former Code of Civil Procedure section 204.7 stated that source lists for jurors “shall include those who are registered voters.” The section also provided that the list should be supplemented from lists from the Department of Motor Vehicles (DMV) in those counties where such supplementation was practical and would not entail “significant cost.” The negative implication of this statutory language was that sole reliance on voter registration lists was permissible where supplementation was impractical or costly. We presume this statute was constitutional. “ ‘In considering the constitutionality of a legislative act we presume its validity, resolving all doubts in favor of the Act. Unless conflict with a provision of the state or federal Constitution is clear and unquestionable, we must uphold the Act. [Citations.]’ ” (County of Sonoma v. State Energy Resources Conservation etc. Com. (1985) 40 Cal.3d 361, 368 [220 Cal.Rptr. 114, 708 P.2d 693], quoting California Housing Finance Agency v. Elliot (1976) 17 Cal.3d 575, 594 [131 Cal.Rptr. 361, 551 P.2d 1193].) Our past decisions, and those of other courts, are in accord. As discussed, ante, at page 494 footnote 7, we held in 1972 that sole reliance on voter registration lists was not itself constitutionally invalid. (Sirhan, supra, 7 Cal.3d at pp. 749-750.) Moreover, the federal circuits are unanimous on this point. Interpreting the Jury Selection and Service Act of 1968 (28 U.S.C. §§ 1861-1867), circuit courts of appeal have routinely held sole reliance on voter registration lists does not violate the fair cross-section rule absent some evidence of active discrimination. United States v. Cecil (4th Cir. 1988) 836 F.2d 1431 (cert. den. (1988) 487 U.S. 1205 [101 L.Ed.2d 883, 108 S.Ct. 2846]), is illustrative. In that case, the United States Court of Appeals for the Fourth Circuit opined that sole use of voter registration lists “cannot be described ‘as “systematically” excluding classes that do not register in proportion to their numbers’; it is a process that comports with the ‘need for efficient jury selection’ even though it may not ‘perfectly reflect population.’ Nor does it follow that the voter registration lists do not satisfy the fair cross-section . . . [requirement] simply because . . . members of one group neglected to register in the same proportion as was their share in the overall population. The Constitution and the [federal] statute do not require such perfection. It is sufficient that the system adopted provides a fair cross-section and we find both common sense and precedent establish that if the voter registration lists do this they are not tainted by some affirmative form of discrimination.” (Id. at pp. 1448-1449; see generally id. at pp. 1444-1451, and cases cited; Annot., Construction and Application of Provisions of Jury Selection and Service Act of 1968 (28 USCS §§ 1861-1867) Governing Plans for, and Manner of, Selecting Federal Grand and Petit Jurors (1973) 17 A.L.R.Fed. 590, 608, § 7[a] and cases cited.) Significantly, the rule laid down in Sirhan, supra, 7 Cal. 3d at pages 749-750, as well as the complementary rule of law in numerous federal cases, existed before and during defendant’s trial. Former Code of Civil Procedure section 204.7 was also in force at that time. In light of these persuasive authorities, we conclude defendant fails to demonstrate the county’s race-neutral procedures for using voter registration lists to assemble the county’s master jury list was constitutionally impermissible and, accordingly, we conclude the trial court correctly denied the motion to quash. 2. Former Code of Civil Procedure Section 204.7 In conjunction with his pretrial challenge to the composition of the jury venire, defendant also claimed the master jury list was assembled in violation of former Code of Civil Procedure section 204.7, at the time a relatively new statute. (Stats. 1980, ch. 81, § 35, p. 207, elf. July 1, 1981.) The evidence produced in support of the motion showed that at the time of his 1981 trial, Kern County relied solely on voter registration rolls to compile its jury lists. Although an attempt was made to incorporate and integrate the names of those holding driver’s licenses and identification cards from the DMV, the county intended to complete this project only in time to select the 1982 master jury list. The jury list was assembled once a year and the list in use at the time of defendant’s motion (November 1981) had been compiled the previous year. For Kern County to expand and use multiple source lists any sooner would have cost between $15,000 and $40,000 for a computer program to eliminate duplicate names (in order to maintain the randomness of the selection procedure). At the time of defendant’s trial, former Code of Civil Procedure section 204.7 provided that “(a) Source lists of jurors shall identify persons who reside in the county, and who are 18 years of age or older, shall include those who are registered voters, and to the extent that systems for producing jury lists can be practically modified, without significant cost, shall also include those who have been licensed or issued an identification card pursuant to Article 3 . . . and Article 5 ... of Chapter 1 of Division 6 of the Vehicle Code. Qualified jury lists and master jury lists derived from the source lists shall be prepared so as to reasonably minimize duplication of names.” (Italics added.) The trial court denied defendant’s motion at a November 1981 hearing, concluding that the section did not become effective until January 1982, “if then.” In addition, the court specifically declined to make a finding on the financial feasibility of the immediate use of multiple source lists. Although the trial court did not explain its decision regarding the effective date of the newly enacted statute, it appears the court believed that because Kern County assembled its master jury list only once each year and the list for 1981 had already been chosen, the new statute would affect only the master jury list for 1982, which would supplant the previous year’s jury list in January 1982. The trial court did not cite any authority for its interpretation of the former code section, making it difficult to evaluate the correctness of its ruling. However, even assuming arguendo the trial court erred, defendant cannot prevail. As the evidence below made clear, Kern County was, at the time defendant made his motion, in the process of complying with the statutory requirement to integrate DMV lists into the master jury list. Recognizing that mandating overnight changes was unwise, the Legislature only required that “systems for producing jury lists” be modified to include DMV lists if such changes could be done “without significant cost.” Because the record shows the cost of immediate compliance would have been several thousand dollars, and that compliance would occur shortly, we conclude the motion was properly denied because the record shows the master jury list could not be “practically modified, without significant cost . . . .” (Former Code Civ. Proc., § 204.7.) 3. Wheeler Error During voir dire, all but four Spanish surnamed persons were excused for cause by either the prosecution or the defense. When the remaining four were peremptorily challenged by the prosecutor, defendant objected, claiming the prosecutor was exercising his peremptory challenges to improperly exclude Spanish surnamed persons from the jury. (People v. Wheeler (1978) 22 Cal.3d 258 [148 Cal.Rptr. 890, 583 P.2d 748].) The trial court denied the motion, finding defendant failed to demonstrate a prima facie showing that the prosecutor was relying on group rather than specific bias. We agree the court properly denied the motion. It is now well established that “peremptory challenges may not be used to exclude from a jury, solely because of a presumed ‘group bias,’ all or most members of an identifiable group of citizens distinguished on racial, religious, ethnic, or similar grounds.” (People v. Snow (1987) 44 Cal.3d 216, 222 [242 Cal.Rptr. 477, 746 P.2d 452].) Such improper exercise of peremptory challenges violates article I, section 16, of the California Constitution (People v. Turner (1986) 42 Cal.3d 711, 716 [230 Cal.Rptr. 656, 726 P.2d 102]; Wheeler, supra, 22 Cal.3d at pp. 276-277), as well as the equal protection clause of the United States Constitution. (Batson v. Kentucky (1986) 476 U.S. 79 [90 L.Ed.2d 69, 106 S.Ct. 1712].) “If a party believes his opponent is using his peremptory challenges to strike jurors on the ground of group bias alone, he must raise the point in timely fashion and make a prima facie case of such discrimination to the satisfaction of the court. First, ... he should make as complete a record of the circumstances as is feasible. Second, he must establish that the persons excluded are members of a cognizable group within the meaning of the representative cross-section rule. Third, from all the circumstances of the case he must show a strong likelihood that such persons are being challenged because of their group association rather than because of any specific bias.” (Wheeler, supra, 22 Cal.3d at p. 280; see also Snow, supra, 44 Cal.3d at p. 222.) If the trial court finds the moving party has made a prima facie case, the burden shifts to the opponent to explain its peremptory challenges. (People v. Johnson (1989) 47 Cal.3d 1194, 1216 [255 Cal.Rptr. 569, 767 P.2d 1047].) Defendant clearly raised the issue in timely fashion and made as complete a record as possible. Moreover, contrary to the People’s argument, defendant’s reliance on Spanish surnamed persons as a category of excluded jurors is permissible. (See Morales, supra, 48 Cal.3d at p. 543.) We conclude, however, that the trial court properly found defendant failed to demonstrate “from all the circumstances of the case” a “strong likelihood” that the prosecutor’s use of peremptory challenges to excuse the four Spanish surnamed jurors was based on group, rather than specific, bias. Because defendant thus failed to make a prima facie showing of a constitutional violation, the prosecutor’s burden of justification never arose. An examination of the voir dire proceedings supports this conclusion. Mrs. Sosa was the first Spanish surnamed person peremptorily challenged by the prosecutor. She stated she was a cook for the Child Development Center and that her husband was director of maintenance and transportation at a local school. She had three adult children and had lived in Kern County for eleven years. When asked about the death penalty, she replied, “That is kind of scary” and that she was “absolutely” opposed to the death penalty on religious grounds. On later questioning, she was asked whether she would impose the death penalty in a proper case under proper instructions; she said, “Yes, I guess.” Mr. Arrambide was questioned shortly after Mrs. Sosa. He was a labor contractor, married, and had five children. He had lived in Kern County since 1948 and did not read a newspaper. He seemed distracted because he had lost a job that day due to his jury duty and was concerned that he would lose more jobs. He operated five work crews and explained that “if I am not there, well, they say that guy is not interested in the job .... Some farmers understand, but some don’t.” Later, when asked whether he would lose many jobs by serving on defendant’s jury, he admitted he did not know. When asked about the death penalty, Mr. Arrambide stated his belief that only God could take a man’s life, but that he could vote to impose the death penalty. Later, he said he could not, and appeared confused by the questioning. There was some suggestion of a language problem. Defendant first raised the Wheeler issue after Sosa and Arrambide were excused. The trial court denied the motion, stating, “I certainly don’t think there is at this particular point an indication that there is an intention to rid this jury of all Spanish surnamed individuals. fl[] I tell you now that I do not know the reason for the excusing of [Mrs.] Sosa but it’s very obvious why Mr. Arrambide was excused. Motion is denied at this point. But I want to find that there is no obvious reason for the excusing of Mrs. Sosa.” A few days later, Mr. Lara was questioned. A mechanic, Lara was married, had no children, and had lived in the county for 19 years. He initially stated he would always choose life over death and was absolutely opposed to the death penalty. The prosecutor interposed a challenge for cause which was ultimately denied after Lara was questioned by defense counsel. Lara admitted he could conceive of a crime for which death might be appropriate and, after some pointed questioning, he eventually conceded he could vote for the death penalty if he were retained on the jury. After Mr. Lara was questioned, counsel for both defendant and Cebreros announced they were satisfied with the panel. The prosecutor then exercised one of his remaining peremptory challenges to excuse Juror Lara. Defendant renewed his Wheeler motion but the trial court again denied it, stating, “I am keeping [track] of it and I made a finding that I couldn’t see any reason with Mrs. Sosa. But with Mr. Lara, it’s very obvious when I first asked him about the death penalty he indicated he was opposed to it. I don’t think [the prosecutor’s challenge] was done for any racist reason whatsoever and the court will make such a finding.” Counsel argued briefly but to no avail that although Mr. Lara initially expressed personal opposition to the death penalty, his later responses on voir dire showed he had modified his position in that regard. Mr. Mercado was the final Spanish surnamed person on the panel. At the beginning of the voir dire, the trial judge admitted that he knew Mr. Mercado due to a prior association between the judge’s wife and Mercado’s mother. Mr. Mercado affirmed that the connection would not affect his ability to be impartial. Mr. Mercado was a high school math teacher, having graduated from Fresno State. His wife was a junior high school teacher and they had one child, then two years old. He stated he read the local paper regularly but not thoroughly, and had no recollection of defendant’s case, although he knew the brother of one of the witnesses (Glen Blackford). He stated he was in favor of the death penalty but could keep an open mind. Although his cousin worked for the California Highway Patrol and he had a few friends who were deputy sheriffs, he claimed that he would not accord a law enforcement officer’s testimony undue weight. He admitted that while sitting as an alternate, he might be thinking about his high school baseball team because they were due to begin preconditioning, but he would probably be able to set those thoughts aside. Mr. Mercado then admitted he had suffered two arrests in his life. In the first, he was arrested for “grand theft auto” when he was 18 years old. The matter was reduced to misdemeanor joyriding and he received probation. In the second, he recounted that while in college, he and a Black friend were confronted by eight college football players. The players made some racially derogatory remarks and a fight ensued. When the police arrived, the eight players had fled but police arrested Mercado’s friend for being drunk in public. When Mercado attempted to intervene by offering to drive his friend home, he was arrested for obstructing an officer in the performance of his duties. The charges were later dropped. After the prosecutor used a peremptory challenge to remove Mr. Mercado, the fourth and final Spanish surnamed juror, defendant renewed his Wheeler motion a second time. The trial judge stated “Gentlemen, this young man, and I have known [Mercado] a long time. I was shocked to hear about his run ins with the police. I was unaware of it. I think the district attorney has ample grounds under those circumstances.” Defendant first contends that the fact that the prosecutor struck all four of the remaining Spanish surnamed potential jurors from the panel demonstrates a strong likelihood of an impermissible motivation. Although the removal of all members of a certain group may give rise to an inference of impropriety (Wheeler, supra, 22 Cal.3d at p. 280), we cannot say this factor was dispositive on this record. It is clear the trial court was “aware of [its] duty under Wheeler to be sensitive to the manner in which peremptory challenges were used.” (Johnson, supra, 47 Cal.3d at p. 1221.) After carefully scrutinizing the voir dire proceedings, the trial court—clearly aware the prosecutor had removed the remaining Spanish surnamed venirepersons— held defendant failed to demonstrate a strong likelihood based on “all the circumstances of the case” that the prosecutor’s exercise of his peremptory challenges were based on group bias. We reiterate that ruling on Wheeler motions “ ‘requires trial judges to make difficult and often close judgments. They are in a good position to make such determinations, however, on the basis of their knowledge of local conditions and of local prosecutors.’ [Citation.] They are also well situated to bring to bear on this question their powers of observation, their understanding of trial techniques, and their broad judicial experience. We are confident of their ability to distinguish a true case of group discrimination by peremptory challenges from a spurious claim . . . .” (Wheeler, supra, 22 Cal.3d at p. 281, quoting Kuhn, Jury Discrimination: The Next Phase (1968) 41 So.Cal.L.Rev. 235, 295, fn. 5; see also Johnson, supra, 47 Cal.3d at pp. 1219-1222.) Applying this standard of giving considerable deference to the determination of the trial court, “we see no good reason to second-guess [the trial court’s] factual determination” (Johnson, supra, at p. 1221) that the prosecutor was not motivated by bias against Hispanics. Defendant also contends the trial court should have found he made a prima facie showing because aside from their ethnicity, the four excused jurors were otherwise “as heterogeneous as the community as a whole.” (Wheeler, supra, 22 Cal.3d at p. 280.) While this fact may, under some circumstances, support a finding of a prima facie case, comparisons between jurors is not often a fruitful exercise. “[T]he very dynamics of the jury selection process make it difficult, if not impossible, on a cold record, to evaluate or compare the peremptory challenge of one juror with the retention of another juror which on paper appears to be substantially similar.” (Johnson, supra, 47 Cal.3d at p. 1221.) Such a comparison “is highly speculative and less reliable than the determination made by the trial judge who witnessed the process by which the defendant’s jury was selected.” (Ibid.) Although defendant argues the prosecutor’s voir dire of the jurors in question was “superficial if not exactly desultory” (see Wheeler, supra, 22 Cal.3d at p. 281), the record does not support this assertion; our independent examination of the record does not reveal the voir dire of the four potential jurors was either limited or desultory, or was in any way different from the other jurors on the panel. Defendant thus fails to convince us that our traditional deference to a trial court’s ruling on a Wheeler motion is inappropriate. We conclude the trial court properly found defendant failed to make a prima facie showing of a strong likelihood that the prosecutor’s challenges were motivated by group, rather than specific, bias. 4. Witherspoon/ Witt Error During routine questioning on voir dire, venireman Giangregorio volunteered that he did not believe in capital punishment. Later, when questioned about that topic by the trial judge, the following colloquy occurred: “Q: How do you feel about the death penalty? “A: I am against it, your Honor. “Q: Are you against it in every case? “A: Every instance. I do not believe in it.” The prosecutor’s motion to exclude for cause was thereafter granted over a defense objection. Defendant now contends Giangregorio’s excusal violated the precepts laid down in Witherspoon v. Illinois (1968) 391 U.S. 510 [20 L.Ed.2d 776, 88 S.Ct. 1770] (Witherspoon). As he recognizes, however, the high court limited Witherspoon, establishing a less stringent standard, in part because of the modern trend against permitting a capital jury to act with unfettered discretion. (Wainwright v. Witt (1985) 469 U.S. 412, 422 [83 L.Ed.2d 841, 850, 105 S.Ct. 844] (Witt).) Witt requires that the trial court determine “whether the juror’s views would ‘prevent or substantially impair the performance of his duties as a juror in accordance with his instructions and his oath.’” (Id. at p.424 [83 L.Ed.2d at pp. 851-852].) “Under Witt, therefore, our duty is to ‘examine the context surrounding [the juror’s] exclusion to determine whether the trial court’s decision that [the juror’s] beliefs would “substantially impair the performance of his duties . . .” was fairly supported by the record.’ ” (People v. Miranda (1987) 44 Cal.3d 57, 94 [241 Cal.Rptr. 594, 744 P.2d 1127], quoting Darden v. Wainwright (1986) 477 U.S. 168, 176 [91 L.Ed.2d at p. 154].) Defendant first contends we should retain the stricter Witherspoon standard as a matter of state constitutional law. (See Cal. Const., art. I, § 16 [right to trial by jury].) However, we have already adopted the Witt standard, because it “ ‘make[s] good sense, and because California courts have generally followed the teachings of the high court in determining when a prospective juror properly may be excused for cause because of his views regarding capital punishment....’” (People v. Guzman (1988) 45 Cal.3d 915, 955 [248 Cal.Rptr. 467, 755 P.2d 917], quoting People v. Ghent (1987) 43 Cal.3d 739, 767 [239 Cal.Rptr. 82, 739 P.2d 1250]. He next argues that Giangregorio’s excusal was improper even under the Witt standard. Giangregorio’s expressed antipathy to the death penalty in “every instance,” however, would undoubtedly “substantially impair the performance of his duties as a juror . . . .” (Witt, supra, 469 U.S. at p. 424 [83 L.Ed.2d at p. 851].) Although defendant submits the trial court should have explained to Giangregorio that it was his civic duty to set aside his personal feelings and obey the law, we have previously rejected that notion, finding nothing in Witherspoon that obligates a trial court to so instruct a juror. (Miranda, supra, 44 Cal.3d at p. 96.) We conclude prospective juror Giangregorio was properly excused from the jury. B. Guilt Phase Issues 1. Exclusion of Expert Testimony Regarding Eyewitness Identification At trial, defendant offered the testimony of Dr. Elizabeth Loftus, an expert on eyewitness identifications. Dr. Loftus would have testified to the following: To provide a basis for her expert opinion, she read the police reports in the case as well as the transcript of the preliminary examination. In addition, she viewed the photographic lineup and discussed the case with defense counsel. Based on this information, she determined the following factors could have influenced the eyewitness identification in this case: (1) stress or fear; (2) violence; (3) weapon focus; (4) retrograde amnesia; (5) ingestion of drugs or alcohol; and (6) a photo-biased identification. She did not intend to give an opinion as to whether any particular identification was accurate but only that these six factors are known to affect the accuracy of eyewitness identifications in general. Moreover, she opined that the information she would provide was beyond the common experience of most jurors and that her testimony could be of assistance to the jury. The prosecutor objected to Dr. Loftus’s proposed testimony, contending that the accuracy of eyewitness identifications was a matter of common sense for the jury, that Dr. Loftus could not testify as to the accuracy of any particular identification, and that cross-examination coupled with appropriate jury instructions would form an adequate basis from which the jury could decide whether or not to rely on Boender’s identification of defendant. In addition, the prosecutor cited several cases in which the type of expert testimony the defense offered had been excluded. The trial court, although finding Dr. Loftus qualified to testify as an expert and that her testimony would not consume an undue amount of time, sustained the prosecution’s objection. As both defendant and the People acknowledge, the resolution of this issue is controlled by People v. McDonald (1984) 37 Cal.3d 351 [208 Cal.Rptr. 236, 690 P.2d 709, 46 A.L.R.4th 1011], filed after defendant’s trial. McDonald involved the murder of Jose Esparza on a public sidewalk, viewed from varying distances by seven witnesses who identified McDonald as the killer. McDonald offered the testimony of Dr. Shomer, who “proposed to inform the jury of various psychological factors that may affect the reliability of eyewitness identification, and to ‘help to counter some common misconceptions’ about the process.” (Id. at p. 361.) Specifically, Dr. Shomer would have testified that the following factors affected the reliability of eyewitness identifications: “the observer’s state of mind, his expectations, his focus of attention at the time, the suddenness of the incident, the stressfulness of the situation, and the differences in the race and/or age of the observer and the observed.” (Ibid.) Following a line of appellate decisions that upheld the exclusion of such evidence, the trial court in McDonald excluded Dr. Shomer’s testimony. The defendant was convicted of murder and sentenced to death. We reversed. “When an eyewitness identification of the defendant is a key element of the prosecution’s case but is not substantially corroborated by evidence giving it independent reliability, and the defendant offers qualified expert testimony on specific psychological factors shown by the record that could have affected the accuracy of the identification but are not likely to be fully known to or understood by the jury, it will ordinarily be error to exclude that testimony.” (McDonald, supra, 37 Cal.3d at p. 377.) However, exclusion of such evidence requires reversal only if it results in a miscarriage of justice. (People v. Brown (1985) 40 Cal.3d 512, 526-527 [220 Cal.Rptr. 637, 709 P.2d 440]; McDonald, supra, at p. 376; see also People v. Watson (1956) 46 Cal.2d 818, 836 [299 P.2d 243].) Although an appellate court should, in the usual case, defer to a trial court’s decision admitting or excluding expert testimony (McDonald, supra, 37 Cal.3d at p. 377), the trial in defendant’s case took place prior to our decision in McDonald and the trial court took no guidance from the reasoning therein. Even assuming arguendo the trial court erred in excluding the proffered expert testimony, however, we find the error was harmless. We begin by noting that several of the critical factors identified in McDonald are present in this case. Boender’s identification of defendant was indisputably a “key element” of the People’s case. Also, there is no dispute that Dr. Loftus was a qualified expert on the subject of eyewitness identifications. We thus must examine whether Boender’s identification was “substantially corroborated” such that it had “independent reliability.” Once again, McDonald is instructive. In McDonald, supra, 37 Cal.3d 351, no evidence linked the defendant to the crime other than the eyewitness identifications. The eyewitnesses in McDonald were equivocal, voicing various degrees of certainty, with one actually asserting that the defendant was definitely not the killer. Finally, the defendant had a strong alibi defense: several witnesses testified that he was in Alabama on the day of the killing and their testimony was supported by physical evidence in the form of dated postcards and phone bills. The identifications therefore were not corroborated by evidence giving them independent reliability. In the present case, by contrast, Boender was positive that defendant was one of the two assailants and his identification was bolstered by (1) his recognition of defendant from the botched robbery attempt two days earlier; (2) Maxwell’s statement to police, which dovetailed with Boender’s description of the crimes and gave defendant a motive to kill Boender; and (3) Maxwell’s descriptions of defendant and Cebreros, which matched Boender’s descriptions of the assailants given to police the day after Allen’s murder. Although Maxwell was admittedly not the most veracious witness, we cannot agree with defendant that her testimony must be wholly disregarded. To the extent Maxwell’s testimony was consistent with Boender’s version of events, it provides some corroboration for Boender’s eyewitness identification of defendant. Moreover, unlike in McDonald, physical evidence linked defendant to the crime. The baggie of marijuana found in Cebreros’s possession was identical to that taken from Boender’s apartment. In addition, the gun found in his possession was similar to the one that Boender described as having been wielded by defendant. Finally, the roll of duct tape bore defendant’s fingerprints, thus supporting Maxwell’s story that defendant planned to use it to bind Boender during the January 21st robbery attempt. Although none of these items points unerringly towards defendant’s guilt, they constitute links in the chain of evidence against him and thus provide some corroboration of Boender’s identification of defendant as the guilty party. Due to the strength of the evidence corroborating Boender’s eyewitness identification of defendant, we cannot conclude the trial court’s exclusion of his proffered expert evidence resulted in a miscarriage of justice. (McDonald, supra, 37 Cal. 3d at p. 376.) Even assuming error, it was harmless. In a related claim, defendant contends the trial court abused its discretion when, during voir dire, it sustained the prosecutor’s objection to defense questions that sought to elicit the opinions of potential jurors concerning the effects of stress on perception. Defendant argues that these questions would have demonstrated that the information Dr. Loftus sought to impart was not within the common knowledge of the jury, thereby undercutting a potential justification for excluding her testimony. The purpose of questioning at voir dire, however, is to assist the attorneys in the exercise of their peremptory challenges, not to provide foundational support for their evidentiary motions. “[Cjounsel should be allowed to ask questions reasonably designed to assist in the intelligent exercise of peremptory challenges whether or not such questions are also likely to uncover grounds sufficient to sustain a challenge for cause.” (People v. Williams (1981) 29 Cal.3d 392, 407 [174 Cal.Rptr. 317, 628 P.2d 869], italics added.) Because the challenged questions at voir dire were not related to aiding the exercise of peremptory challenges but instead were intended to support defendant’s position on an evidentiary question, no abuse of discretion occurred. Defendant apparently recognizes the weakness of his argument by suggesting that responses to his voir dire questions would have helped him decide which jurors to challenge by exposing whether they were aware of the information Dr. Loftus would have offered. Although defendant thus claims the questions would have assisted in the exercise of his peremptory challenges, he is basically asserting that if the trial court excluded Dr. Loftus’s testimony on the ground that it was within the common experience of the jury, then he was entitled to prove through questioning of the jurors that the trial court’s assumption was incorrect. As we have explained, this is not a proper subject of questioning on voir dire. 2. Boender's Identification of Cebreros The day after the murder, police questioned Boender at the hospital. He described the larger of his assailants as over six feet tall, weighing over two hundred pounds, with dark hair thinning on top and combed straight back. Boender also noticed the man carried his arms noticeably away from his body and looked like a “biker.” This description was very similar to Maxwell’s description of Cebreros, given to police the night before. After Cebreros was arrested, police displayed a stack of photographs to Boender, who, upon seeing the picture of Cebreros, exclaimed, “This is the big guy; I’m sure of it.” Maxwell also identified Cebreros from a photographic lineup. Cebreros is six feet, five inches tall, weighs two hundred and twenty pounds, and has hair as described by Boender. After Cebreros was arrested, Boender identified defendant from a separate photographic lineup. Defendant moved to suppress Boender’s out-of-court identification of him, claiming the circumstances under which Boender selected his photograph were unduly suggestive. Cebreros made a similar motion as to Boender’s identification of him. The trial court denied both motions, although it noted that the photographic array that included Cebreros left “a great deal to be desired” because his picture was the only one in the display that matched Boender’s description of the larger assailant. The court stated, however, that, after considering all the facts and circumstances of the case, it could not conclude that there was “a very substantial likelihood of irreparabie misidentification.” (Simmons v. United States (1968) 390 U.S. 377, 384 [19 L.Ed.2d 1247, 1253, 88 S.Ct. 967].) Defendant now attacks the validity of the pretrial identification of Cebreros, arguing that because other evidence linked the two men in the commission of the crimes, the prosecution was able to unfairly bolster its case against defendant by using Boender’s questionable identification of Cebreros. Defendant’s claim fails at the threshold because it does not appear he joined in Cebreros’s motion to suppress in the trial court or otherwise objected to the introduction of Boender’s identification of Cebreros. (Evid. Code, § 353.) Because the alleged flaw in Cebreros’s photographic lineup was that his picture was the only one that matched the witnesses’ description, defendant’s own motion to suppress cannot be fairly read to encompass the theory on which Cebreros’s motion was made. Even assuming the issue was properly preserved for appeal, reversal is not required. “[A] violation of due process occurs if a pretrial identification procedure is ‘so impermissibly suggestive as to give rise to a very substantial likelihood of irreparable misidentification.’ [Citations.] ‘Whether due process has been violated depends on “the totality of the circumstances” surrounding the confrontation. [Citation.]’ The burden is on the defendant to show that the identification procedure resulted in such unfairness that it abridged his rights to due process. [Citation.]” (People v. Sequeira (1981) 126 Cal.App.3d 1, 12 [179 Cal.Rptr. 249]; see also People v. Blair (1979) 25 Cal.3d 640, 659 [159 Cal.Rptr. 818 [602 P.2d 738].) “The factors to be considered in determining whether a lineup is impermissibly suggestive include the opportunity of the witness to view the criminal at the scene of the crime, the witness’ degree of attention, the accuracy of the prior description of the criminal, the level of certainty demonstrated at the confrontation, and the time between the crime and the confrontation, as well as the suggestiveness of the procedure employed. (Manson v. Brathwaite (1977) 432 U.S. 98, 114.)” (Sequeira, supra, 126 Cal.App.3d at pp. 12-13.) In this case, Boender testified he clearly viewed his assailants and he focused on his attackers’ faces in order to identify them if he survived the attack. He was certain of his identification of Cebreros, who matched both his and Maxwell’s descriptions of the larger of the two assailants. Only two days passed between the crime and Boender’s selection of Cebreros’s picture from the photographic array. Although the Cebreros photographic array was somewhat suggestive, we agree with the trial court that the totality of the circumstances does not demonstrate that there was “a very substantial likelihood of irreparable misidentification.” (Simmons v. United States, supra, 390 U.S. at p. 384 [19 L.Ed.2d at p. 1253].) 3. Felony-murder Instructions The People presented the jury with six potential first degree murder theories. In addition to being instructed that it should return a verdict of first degree murder if it found defendant premeditated and deliberated the killing, or killed during a robbery, the jury was also instructed that it could return a verdict of first degree murder if it found the murder was committed during a burglary in which defendant entered Boender’s home with the intent to (1) steal, (2) commit an assault, (3) falsely imprison the victims, or (4) dissuade the victims from testifying. Defendant correctly contends, and the People now concede, that it was error to instruct the jury that it might convict of first degree murder if it found the killing occurred during a burglary in which defendant’s intent was to commit an assault. “In [People v.] Ireland [(1969) 70 Cal.2d 522 [75 Cal.Rptr. 188 (450 P.2d 580, 40 A.L.R.3d 1323)], we rejected the bootstrap reasoning involved in taking an element of a homicide and using it as the underlying felony in a second degree felony-murder instruction. We conclude that the same bootstrapping is involved in instructing a jury that the intent to assault makes the entry burglary and that the burglary raises the homicide resulting from the assault to first degree murder without proof of malice aforethought and premeditation.” (People v. Wilson (1969) 1 Cal.3d 431, 441 [82 Cal.Rptr. 494, 462 P.2d 22].) We thus concluded th
