Opinion LUCAS, C. J. On May 29, 1981, an amended information was filed in San Joaquin County Superior Court charging defendant Morales with murder, and alleging as special circumstances that (1) the murder was intentional and involved the infliction of torture (Pen. Code, § 190.2, subd. (a)(18); further statutory references are to this code unless otherwise indicated), and (2) defendant intentionally killed the victim while lying in wait (id., subd. (a) (15)). In addition, the amended information alleged that defendant personally used deadly weapons, namely, a knife and hammer (§ 12022, subd. (b) ), that he conspired to commit murder (§ 182), and that he forcibly raped the victim (§261, subd. (2)). (The amended information also alleged as special circumstances a robbery-murder (§ 190.2, subd. (a)(17)(i)), a rape-murder (id., subd. (a)(17)(iii)), and a heinous and cruel murder (id., subd. (a)(14)). These three special circumstance allegations, and a robbery charge, were dismissed prior to trial.) On November 24, 1982, the case was transferred to Ventura County after defendant’s motion to change venue was granted. On April 7, 1983, the jury returned its verdict, finding defendant guilty of murder in the first degree, and finding true the two remaining special circumstance allegations. The jury also expressly found that the murder was willful, deliberate and premeditated, that the victim was aware of extreme physical pain inflicted by defendant, and that defendant personally used two deadly weapons (knife and hammer) in the commission of the offense. The jury additionally found defendant guilty of forcible rape and conspiracy to commit murder; the jury specified various overt acts supporting the conspiracy charge. On April 19, 1983, prior to the commencement of the penalty phase, the trial court granted in part defendant’s motion for new trial, ruling that there was insufficient evidence to support the jury’s implied finding of first degree murder by torture. (Following the penalty phase, this ruling was vacated on the People’s motion and the court instead purported to grant judgment notwithstanding the verdict (n.o.v.) as to the jury’s implied finding of first degree torture murder. The People have filed a cross-appeal from this ruling, which we consolidated with the present appeal for purposes of argument.) On April 19, 1983, the penalty phase commenced and, on April 25, the jury returned a death verdict. On June 14, 1983, the trial court denied defendant’s motion to modify the judgment (§ 190.4, subd. (e)), and sentenced defendant to death. This appeal is automatic (§ 1239). As will appear, we have concluded that although the court’s purported judgment n.o.v. must be set aside, in all other respects the judgment should be affirmed in its entirety. I. The Facts The record discloses that defendant and his cousin, Ricky Ortega, plotted to kill Terri Winchell, a woman who had maintained a sexual relationship with Randy Blythe, Ortega’s male lover. (Ortega’s case was severed from defendant’s case prior to trial.) The evidence indicates that Ortega and Blythe had a homosexual relationship between 1979 and 1981; that Blythe met Winchell in 1980 and became her lover; and that Ortega, accordingly, became upset and was overheard threatening to kill himself or Blythe. Thereafter, in late 1980, a few weeks prior to the murder, Ortega told Glenda Chavez that he was angry at Winchell for accusing him of being a homosexual; Ortega threatened to “pay her back” for her remarks. On January 8, 1981, Ortega called defendant and told him he was driving Winchell to defendant’s apartment. Immediately after this conversation, defendant told his girlfriend, Racquel Cardenas, that he was going to do Ortega a favor and “hurt" a girl by strangling her with his belt. Thereafter (according to defendant’s statements to a jailhouse informant, Bruce Samuelson, to Cardenas, and to an acquaintance, Patricia Flores), the men lured Winchell into a car, where defendant attempted to strangle her with his belt until it broke, beat her repeatedly on the head with a hammer until she was unconscious or dead, dragged her body into a field and completed an act of sexual intercourse, and finally stabbed her four times in the chest to assure her death. (A more detailed statement of the facts and evidence is set forth as particular issues are discussed.) Defendant did not testify in his defense, nor did he present any affirmative defenses. Instead, defense counsel relied primarily on contesting the People’s case through cross-examination and argument. (Defendant did present some testimony in an attempt to rebut (1) the positive identification of shoe prints found at the crime scene, and (2) the jailhouse informant’s testimony that he discussed the murder events with defendant.) At the penalty phase, the prosecutor introduced evidence regarding defendant’s prior burglary and robbery convictions. Defendant introduced substantial mitigating testimony from friends, acquaintances and a clinical psychologist, each of whom attested to various aspects of his background and character, including his remorse, childhood traumas and “avoidant personality disorder,” his problems with school and family, his artistic skills and the like. The psychologist, Dr. Carson, testified that in her opinion defendant was acting under extreme emotional or psychological duress when he killed victim Winchell. II. Guilt Phase Contentions A. Denial of Representative Jury 1. Defendant's Showing—Defendant, a person of Hispanic origin, contends that, by reason of defects in the process of selecting jury panels for Ventura County trials, he was denied his constitutional right (U.S. Const., 6th Amend.; Cal. Const., art. I, § 16) to a jury drawn from a representative cross-section of the community. (See Duren v. Missouri (1979) 439 U.S. 357 [58 L.Ed.2d 579, 99 S.Ct. 664]; People v. Wheeler (1978) 22 Cal.3d 258 [148 Cal.Rptr. 890, 583 P.2d 748].) He does not complain of any disparity on his own jury, which included three persons with Hispanic surnames. Instead, he challenges the process by which jurors are selected or exempted from jury duty. According to defendant, although persons of Hispanic origin account for 18.26 percent of all adult persons living in Ventura County, a much smaller percentage of Hispanics actually reported for jury duty on two consecutive sample panels (including his own panel) examined by defendant prior to trial. Thus, of 364 persons reporting for jury duty on February 28, 1983, only 39 (10.71 percent) had Hispanic surnames, and of 424 persons reporting for jury duty on March 7, 1983, only 37 (or 8.73 percent) had such surnames. A defense statistician testified that it was highly unlikely that such small percentages could have occurred if the jury panel was randomly drawn. According to his testimony, based on the number of panelists and the county-wide percentage of Hispanics, the chances of randomly drawing a jury panel containing only 10.71 percent Hispanics was approximately 1 in 1,000, while the chances of randomly drawing a panel containing only 8.73 percent Hispanics was approximately 1 in 10,000. Based on the foregoing statistics, defendant moved the trial court to quash the jury panel. The court, following a pretrial evidentiary hearing, denied the motion on the following grounds: (1) use of Hispanic surnames, without further verification, was too imprecise a method on which to base a claim of systematic exclusion; defendant’s own witness admitted that a variation of 10 to 15 percent could be expected if surnames alone were used; (2) defendant’s own jury was comprised of 25 percent Hispanics, indicating no serious underrepresentation problem existed; (3) the disparities shown by defendant evidently “occurred from perfectly legitimate causes,” such as failure to deliver, or to respond to, jury duty notices, noncitizenship, travel distances, financial burden excuses, and the like. As the court noted, “there’s really no reason for the Court to pick one [cause] over the other in this case”; and (4) the disparities shown by defendant “are not as great as the disparities in the cases that have been cited to the Court.” 2. Ventura County Procedures—Defendant renews his contention based on systematic exclusion or underrepresentation of Hispanics arising from Ventura County’s allegedly lax jury selection processes. The record indicates that the county draws prospective jurors from a pool of approximately 500,000 persons whose names appear on voters’ registration lists and Department of Motor Vehicles records. A computer randomly selects prospective jurors from the pool without regard to race or national origin. Exemptions or excuses are available for such reasons as advanced age, nonresidency, difficulty with the English language, lack of sufficient intelligence, prior felony convictions, travel distance, lack of adequate transportation, extreme financial hardship, physical or mental incapacity, and public health or safety factors. If a person selected for jury duty believes he is entitled to be excused, he must return a written questionnaire and statement under penalty of perjury to the jury commissioner, who later rules on the request. Thereafter, a list is prepared and a special letter sent to each person who failed to respond to the jury summons, requiring him to explain his absence. The commissioner grants or denies excuses based on the reasons given in the questionnaire and statement submitted to the prospective jurors. All persons claiming financial hardship must identify their employers, although no attempt is made to verify that employment. The commissioner maintains a written record noting the policies these various employers have adopted regarding pay for jury duty. The commissioner’s office seldom independently investigates or verifies claimed excuses or exemptions. The office has conducted no studies to determine the number or percentage of Hispanics on voters’ or drivers’ registration lists, or the number of such persons who were excused or exempted by the county’s system of jury selection. During the week of March 7, 1983, 1,950 potential jurors were summoned, but only 424 appeared. Of those not appearing, 103 persons were excused for lack of transportation, and 233 were excused for extreme financial hardship. Similar figures were obtained for the week of February 28. Defendant, offering no specific evidence on the subject, speculates that a large number of these excused persons were Hispanics, and that the disparity disclosed by his statistics may well be the result of the county’s failure to enforce more vigorously its jury selection program. 3. Applicable Legal Principles— The burden was on defendant to make a prima facie showing that he was denied his right to a jury drawn from a representative cross-section of the community, thereby shifting the burden to the People to explain or justify the selection process. The defendant’s showing must include proof that (1) the excluded group is a “distinctive group in the community,” (2) representation of this group is unreasonably small in relation to the number of such persons in the community, and (3) such underrepresentation results from a “systematic exclusion” of the group during the jury selection process. (Duren v. Missouri, supra, 439 U.S. 357, 364 [58 L.Ed.2d 579, 586-587]; see People v. Harris (1984) 36 Cal.3d 36, 50 [201 Cal.Rptr. 782, 679 P.2d 433].) The parties agree that the first prong of the test was satisfied. (See Castaneda v. Partida (1977) 430 U.S. 482, 495 [51 L.Ed.2d 498, 511, 97 S.Ct. 1272].) As to the second prong, the People contend that the “absolute disparity” indicated by defendant’s statistics did not reveal a significant disparity; proof of a 10.71 percent and 8.73 percent Hispanic representation on two sample jury panels assertedly was not legally significant when compared to an 18.26 percent community representation. As the People point out, the resulting absolute disparities (obtained by subtracting the jury representation percentage from the community percentage) amounted to only 7.55 and 9.53 percent. According to the People, these figures are insufficient under federal cases indicating that an absolute disparity in excess of 10 percent must be shown to justify a finding of unreasonable under-representation. (See, e.g., Alexander v. Louisiana (1972) 405 U.S. 625, 630 [31 L.Ed.2d 536, 541-542, 92 S.Ct. 1221] [14 percent disparity sufficient]; Swain v. Alabama (1965) 380 U.S. 202, 208-209 [13 L.Ed.2d 759, 766, 85 S.Ct. 824] [10 percent disparity inadequate]; United States ex rel. Barksdale v. Blackburn (5th Cir. 1981) 639 F.2d 1115, 1127 [absolute disparities ranging from 4.45 to 11.49 percent deemed insufficient]; United States v. Maskeny (5th Cir. 1980) 609 F.2d 183, 190 [less than 10 percent disparity held insufficient].) Defendant urges, however, that we adopt a “comparative disparity” standard which takes into account the relative size of the underrepresented group in the community. (See People v. Harris, supra, 36 Cal.3d 36, 47, fn. 2 [dictum suggesting such a standard could be “helpful” in deciding underrepresentation cases].) According to defendant, the unfairness of a particular exclusion is magnified where the group’s community representation is already relatively small, i.e., a 10 percent disparity is comparatively more unfair to a group comprising only 12 percent of the population (leaving only a minimal 2 percent representation) than to a group comprising 60 percent (leaving a 50 percent representation). Defendant’s calculations indicate that, using a system of comparative disparity, Híspanles were underrepresented by 41 and 52 percent on the two sample panels referred to above. The People, on the other hand, cite several federal cases criticizing the use of a comparative disparity formula. (E.g., United States v. Hafen (1st Cir. 1984) 726 F.2d 21, 23-24, cert. den. (1984) 466 U.S. 962 [80 L.Ed.2d 561, 104 S.Ct. 2179].) In addition, the People question the reliability of the data used in preparing defendant’s statistical analysis: The various figures cited by defendant were obtained by a college instructor, specializing in Hispanic heritage and lifestyles, who examined the various jury lists and counted the Hispanic sounding surnames. No attempt was made to confirm that the names selected were indeed those of persons of Mexican-American background. Moreover, according to the People, the statistics offered by defendant were derived from an inadequate sample: two consecutive jury panels covering a period of only two weeks. The People observe that far more complete surveys were offered in prior cases, especially where the issue was whether any systematic exclusion had occurred. (See, e.g., Duren v. Missouri, supra, 439 U.S. at p. 362 [58 L.Ed.2d at p. 585] [weekly venires over eight-month period]; People v. Harris, supra, 36 Cal.3d 36, 53 [three-month survey of jury panels in Long Beach area].) As for the third prong, systematic exclusion, defendant relies on cases suggesting that a statistical discrepancy which discloses a disproportionate underrepresentation can itself indicate a systematic exclusion, i.e., a disparity “ ‘inherent in the particular jury selection process utilized.’ ” (See People v. Harris, supra, 36 Cal.3d 36, 58, quoting Duren v. Missouri, supra, 439 U.S. at p. 366 [58 L.Ed.2d at p. 588]; People v. Buford (1982) 132 Cal.App.3d 288, 296 [182 Cal.Rptr. 904] [“Duren . . . strongly suggests that in a proper case the second and third prongs of the prima facie case can be satisfied by statistics alone”].) We next review the Buford decision and the subsequent cases which question its analysis. 4. The Buford and Alexander Decisions—Defendant places primary emphasis on the statistical evidence, cited above, indicating that the chances of similar disparities occurring at random were 1 in 10,000 and 1 in 1,000. In Buford, supra, 132 Cal.App.3d 288, involving a similar claim that adult Blacks were underrepresented on Contra Costa County juries, the court employed a “statistical significance” test to conclude that a probability of random chance less than six-tenths of 1 percent (i.e., 1 in 166) was small enough to warrant an inference of systematic exclusion sufficient to shift the burden to the People to explain or justify the county’s practices, (id., at pp. 297-299; see also People v. Harris, supra, 36 Cal.3d 36, 47, fn. 2, and authorities cited.) Buford observed that the defendant in that case had “presented evidence suggesting a plausible systematic explanation for some degree of disparity, i.e., the informal procedure by which Contra Costa County goes about excusing prospective jurors from service. The jury commissioner testified that approximately 40 percent of all prospective jurors are either excused or deferred; that less than 5 percent of those excused or deferred ever submit written verification of their asserted reasons for excuse or deferral; and that approximately 80 percent of the requests . . . are granted over the phone by one of the commissioner’s staff, without benefit of written guidelines. . . . [][] It is doubtful that either the Legislature or the Judicial Council intended that every financial cost be treated as an ‘extreme financial burden.’ (Cal. Rules of Court, appen., § 4.5(b)(2).) Jury service is, after all, a duty as well as a right. Though characterized as a deferral, through successive exercise, the commissioner’s financial hardship policy effectively excuses low-skilled, nonunion employees whose employers usually do not pay for jury service. ‘[E]xcessive excuses . . . can upset the demographic balance of the venire in essential respects.’ (People v. Wheeler, supra, 22 Cal.3d at p. 273.)" (People v. Buford, supra, 132 Cal.App.3d 288, 298-299.) The dissent in Buford concluded that the defendant’s statistics and other evidence failed to show any “extraordinary’’ disparity or bad faith on the county’s part, and that in any event no one has suggested what the county reasonably could do to assure a greater percentage of Blacks on its jury panels, given the necessity of providing excuses for financial or other hardship, medical problems, and the like. (The defendant had suggested the impractical solution of busing Blacks to the courthouse.) Defendant submits that Buford is controlling, and that the evidence presented here was likewise sufficient to create a prima facie case of systematic exclusion. As previously indicated, however, there are some differences in the counties’ excusal practices, such as the requirement of written excuse requests, which suggest that Ventura County is making a greater effort at enforcing its jury summonses. Moreover, the People, noting defendant’s exclusive reliance upon the two jury panels sampled by him, argue that the size of the sample was too small, and the duration of the sample too short, to raise a legitimate inference of systematic exclusion. (In Buford, at least four different panels were scrutinized, and additionally a jury commissioner was questioned about his visual observations of the number of Blacks on Contra Costa County weekly jury panels.) Like the dissent in Buford, we believe that a prima facie case of systematic exclusion or underrepresentation of a distinctive class is not made merely by demonstrating that the county’s 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, In the present case, as in Buford, any juror could apply for exemption or excusal; the evidence here did not indicate that Hispanics were granted a disproportionate number of exemptions or excuses. By contrast, in Duren v. Missouri, supra, 439 U.S. 357, Missouri law automatically exempted all women from jury duty, upon their request. In other words, the underrepresentation of women on state juries was the immediate and direct result of the state’s exemption laws. (See also Taylor v. Louisiana (1975) 419 U.S. 522, 524 [42 L.Ed.2d 690, 694-695, 95 S.Ct. 692] [similar automatic exclusion of women].) No such direct and immediate result was demonstrated here. Cases subsequent to Buford, supra, 132 Cal.App.3d 288, question the validity of many of its assumptions. First, in a series of cases involving similar claims of underrepresentative juries in Contra Costa County, the courts have concluded that a post -Buford tightening of jury excusal procedures (such as requiring written excuse requests, verification of medical excuses, and investigating persons who fail to respond to summonses) indicates that the county is now doing all that can reasonably be expected, despite continuing disparities of the nature disclosed in Buford and the present case. (See People v. Simmons (1985) 164 Cal.App.3d 1070, 1072-1073 [211 Cal.Rptr. 60]; People v. Pervoe (1984) 161 Cal.App.3d 342, 352 [207 Cal.Rptr. 622]; People v. Black (1984) 160 Cal.App.3d 480, 482-483 [206 Cal.Rptr. 744]; People v. Jones (1984) 151 Cal.App.3d 1029 [199 Cal.Rptr. 185].) In People v. Alexander (1985) 163 Cal.App.3d 1189 [210 Cal.Rptr. 306], the defendant raised a similar representative jury claim with respect to Kern County juries, contending that his jury was selected from a panel containing a disproportionately smaller number of Blacks and Spanish surnamed persons than would be expected as a result of random selection. Defendant’s claim was based on the Buford premise that such underrepresentation resulted from unduly lax practices and methods employed by the jury commissioner’s office in excusing persons on grounds of hardship. As Alexander observed, “[t]he record suggests that Kern County follows no written standards in excusing jurors, and does not always require written requests before jurors are excused. Jurors are often excused by telephone . . . .” (P. 1198.) The Alexander court recited that the defendant’s statistics, based on comparing general county population figures with the actual jury venires during August 1982, showed absolute disparities for Blacks and Spanish surnamed persons of 1.8 and 6.2 percent respectively. Defendant’s expert testified that the chances of such disparities occurring randomly were one in ten million for Blacks, and one in one million for Spanish surnamed persons. Alexander nonetheless characterized as “speculative” Buford's assumption (supra, 132 Cal.App.3d 288) that a disproportionate number of minority group members asked for and received an excuse from jury service, observing that no statistical information had been furnished to support that thesis. (163 Cal.App.3d at pp. 1200-1201.) Alexander likewise noted that no statistical evidence had been offered to show that reforms of the county’s standards and practices for excusing jurors, such as those suggested by Buford, would substantially reduce the disparity. (P. 1201.) As the court stated, “The fact is, without more factual information, accurate conclusions regarding the cause of the disparity cannot be drawn and any attribution of the cause is wholly speculative. At a minimum, it should be known what the absolute disparity is between minorities in the general population and the number who appear on the jury venire. To the extent that the absolute disparity may be due to economic, cultural, social or language considerations, the difference must be deemed to be ‘unavoidable.’ (See People v. Harris, supra, 36 Cal.3d at p. 59.)” (163 Cal.App.3d at p. 1201.) Alexander also observed that the defendant’s use of figures derived from the general population, rather than from those eligible to vote, “skews the basic statistics toward showing a larger absolute disparity by an amount unknown. Common experience dictates that the percentage of minorities appearing in the general census figures who are statutorily ineligible for jury service must be large. [Fn. omitted.] Yet those ineligible are included in the gross population figures utilized in the statistics presented by appellant.” (163 Cal.App.3d at p. 1202.) Alexander concluded that because of the difficult proof problems in these cases, we should hesitate to assume too readily that the statistical disparity is attributable to causes over which the courts have control. “In reality, it may well be that the amount of the absolute disparity attributed to the procedure of informally excusing jurors is infinitesimal and inconsequential when compared to the other major causes of such disparity. Only further proof and factual information will clarify the significance of the practices utilized in excusing jurors. At this point, attributing the statistical disparity entirely to the practice of orally excusing jurors for undue hardship without written standards would not appear to be justified. Nor should an assumption of such speculative causation serve as a basis for reversal of a criminal conviction.'''’ (163 Cal.App.3d at p. 1203, italics added.) Despite the foregoing comments, Alexander stressed that trial courts should continue to assure compliance with all statutory and rule requirements regarding excusal from jury service. (163 Cal.App.3d at p. 1203.) The court also observed that because the People had presented almost no rebuttal evidence, relying on the pre-Harris rule forbidding challenges based upon gross population statistics, rather than “voter eligible” statistics, a remand would be appropriate to allow the People to present rebuttal evidence and to enable the trial court to “rule upon this issue in light of such evidence and comments and guidelines herein.” (P. 1204, fn. omitted.) The court’s order recited that the case was remanded for hearing on the question whether Kern County “was and is doing all that it reasonably may be expected to do to assure” representative juries. (P. 1206.) 5. Conclusion—We conclude that defendant here did not make a prima facie showing sufficient to shift the burden of explanation or justification to the People. First, his statistical showing was based upon an inadequate sample. Certainly, no case cited by defendant has held that a prima facie case of systematic exclusion can be made based on statistics derived from only two consecutive sample jury panels. The sample was too small in size, and too short in duration, to support a finding of unreasonable underrepresentation or systematic exclusion. Significantly, Buford distinguished an earlier case (People v. Mooring (1982) 129 Cal.App.3d 453 [181 Cal.Rptr. 71]) on the basis, among others, that “the statistical evidence in that case was more limited as to time . . . .” (132 Cal.App.3d 288, 299, fn. 5.) In Mooring, the defendant unsuccessfully asserted a claim that residents of Richmond were underrepresented on county jury panels. Like defendant’s presentation herein, the statistical evidence in Mooring was drawn from only two jury panels; the disparity figures (11.36 percent county-wide distribution; 6.79 and 7.11 percent jury panel representation) were quite similar to those presented here. The Mooring court characterized those figures as “insubstantial.” (129 Cal.App.3d at p. 459.) Second, unlike the situation in Duren, supra, 439 U.S. 357, where all women were automatically excluded, defendant merely showed possible laxity in enforcing race/class neutral excusal practices. Such a showing fails to constitute a prima facie case of systematic exclusion of those minority groups affected by such practices. Third, Ventura County’s jury selection practices, including the requirement of a written request for excuse or deferral, signed under penalty of perjury, adequately distinguish Buford and would support a finding (like the Contra Costa County decisions which followed Buford) that Ventura County is already doing all it reasonably can to assure a representative jury. We conclude that defendant’s showing was insufficient to raise a prima facie case of systematic underrepresentation. B. Premeditated-murder Finding The jury was instructed on three separate theories of first degree murder, namely, premeditated murder, murder by torture, and murder by lying in wait. (See § 189.) The jury found defendant guilty of first degree murder, and also expressly found the murder was premeditated. Thus, although defendant challenges the jury’s implied findings of lying-in-wait murder and torture murder, if the premeditated-murder finding is sustained we need not consider defendant’s contentions regarding these alternative theories of first degree murder. (We do, however, discuss some of these contentions in connection with our review of the lying-in-wait and torture-murder special-circumstance findings.) Accordingly, we turn next to the issues which bear on the premeditated-murder finding. Defendant acknowledges the jury’s special finding of premeditated murder, but argues that (1) there was no statutory basis for that finding, and (2) the jury was not instructed that such a finding must be based on proof beyond a reasonable doubt. Neither point has merit. Section 1150, with exceptions not pertinent here, requires a “general verdict.” (See also § 1152 [special verdicts].) Defendant characterizes the jury’s finding as a forbidden special verdict. We disagree. As we pointed out in People v. Burgener (1986) 41 Cal.3d 505, 537 [224 Cal.Rptr. 112, 714 P.2d 1251], a special verdict “presents conclusions of fact and leaves to the court the task of drawing conclusions of law and rendering judgment upon them where the jury is unable to do so.” In the present case, of course, the jury itself rendered additional findings which fully resolved all counts submitted for its consideration. In Burgener, the trial court asked the jury to make a special finding as to whether or not the murder was committed with express malice and with deliberation and premeditation. We held that such special findings were appropriate under section 190.4, subdivision (a), which requires a special finding “on the truth of each alleged special circumstance.” A finding as to malice and premeditation was deemed appropriate to support the felony-murder special-circumstance finding, by reason of Carlos v. Superior Court (1983) 35 Cal.3d 131 [197 Cal.Rptr. 79, 672 P.2d 862] (later overruled in People v. Anderson (1987) 43 Cal.3d 1104, 1138-1139 [240 Cal.Rptr. 585, 742 P.2d 1306]), and its “intent to kill” requirement. (Burgener, supra, 41 Cal.3d at pp. 536-538.) We further observed that, in any event, it was not reasonably probable that a more favorable verdict would have been rendered had the jury not been directed to make a special finding as to malice and premeditation. (P. 538.) Burgener seems controlling here. As in that case, a special finding on the issues of premeditation and deliberation may have been deemed appropriate to support the torture-murder special-circumstance finding, which requires proof of an intentional murder. (§ 190.2, subd. (a)(18).) In any event, the evidence of premeditation and deliberation was overwhelming in this case, and any error in instructing the jury to decide that issue by a special finding was accordingly harmless. Defendant also contends that the court failed to instruct the jury that its special finding should be based on proof beyond a reasonable doubt. We rejected a similar argument in Burgener, supra, 41 Cal.3d 505, 538-540, observing that the jury was adequately instructed regarding the People’s general proof burden and the reasonable doubt standard, and that there was “no reasonable possibility that the jury could have been misled as to the appropriate standard for their special finding on express malice. The instructions taken as a whole indicate that the prosecutor’s burden of proof throughout was proof beyond a reasonable doubt.” (P. 540.) Similarly, in the present case, the instructions repeatedly emphasized the need to apply a reasonable doubt standard in deciding such issues as defendant’s guilt, the degree of his crimes, the truth of the special circumstances, and the weapon enhancement issue. In short, no other standard reasonably could have been applied by the jury. C. Admissibility of Ortega’s Statements Implicating Defendant Accomplice Ortega was tried separately from defendant. Ortega’s former girlfriend, Christina Salaices, was permitted to testify at defendant’s trial regarding her conversation with Ortega, five months prior to the Winchell slaying, wherein Ortega indicated that he was planning to kill Randy Blythe (Ortega’s male lover, who had begun a sexual relationship with victim Winchell). According to Salaices, Ortega expressed his intent to go to Randy’s house, ring his doorbell, stab him when he opened the door, and “turn the knife in him to see the expression on his face.” Ortega also said that “Mikey (defendant Morales) would be with him because Mikey wouldn’t let him stop. Mikey would help him and Mikey wouldn’t let him stop, that Mikey would be there.” In addition, Ortega told Salaices that “if Terri [victim Winchell] was there, that she was gonna get it, too.” 1. Admissibility Under Hearsay Exceptions— Defendant objected on hearsay grounds to the admission of the foregoing statements as they pertained to him, and he renews that objection here. We conclude that the statements were admissible. Defendant and Ortega had been charged with conspiring to murder Winchell, and Ortega’s statements regarding his expectation of defendant’s assistance in a related murder plot were relevant to prove the existence and nature of that conspiracy. The People thus contend that Ortega’s statements were admissible under either (1) the coconspirator’s exception to the hearsay rule (Evid. Code, § 1223), or (2) the state-of-mind exception to that rule (id., § 1250). Defendant properly disputes the applicability of the coconspirator’s exception. Subdivision (a) of section 1223 of the Evidence Code requires that “[t]he statement was made by the declarant [Ortega] while participating in a conspiracy to commit a crime or civil wrong and in furtherance of the objective of that conspiracy.” Yet no evidence was offered to show that Ortega was conspiring with anyone to kill either Blythe or Winchell at the time of his conversation with Salaices, five months prior to Winchell’s murder. (See People v. Irwin (1888) 77 Cal. 494, 504-505 [20 P. 56].) We agree with defendant that, in the absence of proof of an ongoing conspiracy at the time Ortega’s statement was made, section 1223 was inapplicable. (It is also doubtful that the statement to Salaices was “in furtherance” of any conspiracy, rather than mere boasting to a girlfriend.) As for the state-of-mind exception, section 1250, subdivision (a), of the Evidence Code creates a hearsay exception for relevant statements “of a declarant’s then existing state of mind . . . (including a statement of intent, plan, motive . . .),” when the evidence is offered (1) to prove the declarant’s state of mind at that time or any other time, or (2) to explain his acts or conduct. Defendant contends that Ortega’s intentions or state of mind were irrelevant to the case against defendant. The People, on the other hand, assert that, in light of the conspiracy charges against defendant, Ortega’s statements were admissible to show his earlier intent or plan to draw defendant into a conspiracy involving the killing of Blythe, and possibly Winchell. We agree with the People. Ortega’s admitted plan to kill Blythe, his stated assumption or expectation that defendant would help or encourage him in doing so, and his remark that if Winchell were present she would “get it too,” in the aggregate were probative of the question whether the two men later conspired to kill Winchell. 2. Confrontation Clause— Defendant argues that the admission of Ortega’s statements, coupled with Ortega’s unavailability for cross-examination, violated federal confrontation rights guaranteed by the Sixth Amendment. (See Bruton v. United States (1968) 391 U.S. 123, 135-136 [20 L.Ed.2d 476, 484-485, 88 S.Ct. 1620].) But because Ortega’s statements were properly admitted under the well recognized state-of-mind exception to the hearsay rule, the federal confrontation clause would likewise permit admission of such evidence. (See Bourjaily v. United States (1987) 483 U.S. 171, 182-183 [97 L.Ed.2d 144, 157, 107 S.Ct. 2775]; United States v. Inadi (1986) 475 U.S. 387, 393 [89 L.Ed.2d 390, 397, 106 S.Ct. 1121]; Ohio v. Roberts (1980) 448 U.S. 56, 65-66 [65 L.Ed.2d 597, 607-608, 100 S.Ct. 2531].) D. Corpus Delicti of Rape Defendant next argues that the corpus delicti of rape was not established independently of his own statements. More precisely, defendant contends that, apart from his statements, the evidence was insufficient to show that victim Winchell was alive when the act of intercourse took place. (See People v. Stanworth (1974) 11 Cal.3d 588, 604-605, fn. 15 [114 Cal.Rptr. 250, 522 P.2d 1058].) Defendant points to evidence that Winchell did not move or change position following the sex act, and that she died quickly after being stabbed. Defendant notes that a pathologist testified that Winchell was alive when the stabbing occurred, and jailhouse informant Bruce Samuelson testified that defendant told him he raped Winchell before stabbing her; evidently, this was the sole testimony indicating that Winchell was alive when the sex act took place. The People observe that defendant did not raise the corpus delicti objection at trial. (See People v. Rogers (1978) 21 Cal.3d 542, 547-548 [146 Cal.Rptr. 732, 579 P.2d 1048].) In addition, the People cite as evidence of a rape (1) the act itself, including the presence of spermatozoa and the condition of Winchell’s clothing and body; (2) medical testimony that Winchell was probably alive when stabbed; and (3) medical testimony that Winchell could have survived for 10 minutes after being stabbed and beaten on the head. Only slight evidence is required to establish the corpus delicti, which may be inferred from circumstantial evidence. (People v. Towler (1982) 31 Cal.3d 105, 115 [181 Cal.Rptr. 391, 641 P.2d 1253].) The foregoing evidence was sufficient to support a finding of rape. E. Failure to Instruct on Viewing Jailhouse Informant's Testimony With Distrust Defendant next contends that the court erred in failing to instruct the jury, sua sponte, that it should view the testimony of jailhouse informants such as Bruce Samuelson with distrust. We rejected this precise contention in People v. Hovey (1988) 44 Cal.3d 543, 565-566 [244 Cal.Rptr. 121, 749 P.2d 776]. (See also People v. Alcala (1984) 36 Cal.3d 604, 623-624 [205 Cal.Rptr. 775, 685 P.2d 1126].) Here, the jury was told about Samuelson’s criminal record, and also was informed that the district attorney had agreed to recommend a favorable sentence for Samuelson’s pending auto theft and forgery charges, in return for his testimony incriminating defendant. Moreover, the jury was given standard instructions on assessing a witness’s credibility, and viewing oral admissions with caution. The court had no sua sponte duty to give additional instructions on assessing jailhouse informant testimony. III. Special Circumstances Issues A. Lying-in-wait Murder The jury found true the lying-in-wait special-circumstance allegation (see § 190.2, subd. (a)(15) [“[t]he defendant intentionally killed the victim while lying in wait”]). Defendant challenges the foregoing finding on several grounds. The instructions told the jury that the special circumstance required proof of an intentional murder committed while lying in wait, and that “[fjying in wait requires the following elements: waiting, watching, and concealment. . . . The element of concealment . . . may manifest itself either by an ambush or by the creation of a situation where the victim is taken unawares even though he sees his murderer. While concealment is an element . . . , it is only a concealment which puts the defendant in a position of advantage from which it can be inferred that lying in wait was part of the defendant’s plan to take his victim by surprise.” (Italics added.) Finally, the jury was told that if it had a reasonable doubt whether “a perceptible interruption separates the period of concealment and watchful waiting from the period during which the killing takes place, you must find that special circumstance is not true.” 1. Insufficient Instructions—Defendant argues that the foregoing instructions were inaccurate in failing to require an actual physical concealment. We disagree. Before we discuss the applicable legal principles, however, we briefly summarize the evidence in this case as it pertains to the lying-in-wait issue. Accomplice Ortega asked victim Winchell to accompany him to a shopping mall to find a gift for a friend. After learning from Ortega that the couple would be arriving soon to pick him up, defendant armed himself with a belt, knife and hammer, telling his girlfriend Racquel Cardenas that he was going to do Ortega a favor and “hurt” a girl by strangling her with his belt. When Ortega and Winchell arrived, defendant climbed in the backseat, directly behind Winchell in the front seat. After Ortega had driven through town to a more isolated location, defendant reached over the seat and attempted to strangle Winchell with the belt. The belt broke, and then he began to beat her head repeatedly with the hammer. Winchell’s cries for help from driver Ortega indicated that she was taken by surprise, and was previously unaware of any plan to harm her. Defendant argues that there was insufficient evidence of his concealment from victim Winchell; indeed, the record is clear that Winchell was aware that defendant was seated behind her during the ride. Defendant argues that the foregoing lying-in-wait instructions improperly permitted the jury to predicate a lying-in-wait finding upon a mere concealment of defendant’s purpose, rather than actual concealment of his person. Contrary to defendant’s position, however, the cases have indicated that physical concealment from, or an actual ambush of, the victim is not a necessary element of the offense of lying-in-wait murder. (People v. Sutic (1953) 41 Cal.2d 483, 492 [261 P.2d 241] [concealment in ambush unnecessary]; People v. Tuthill (1947) 31 Cal.2d 92, 100-101 [187 P.2d 16] [victim aware of defendant’s physical presence prior to attack]; People v. Byrd (1954) 42 Cal.2d 200, 208-209 [266 P.2d 505] [defendant waited for four hours in front of his former wife’s home, entered it, conversed with her, and shot her]; People v. Sassounian (1986) 182 Cal.App.3d 361, 407 [226 Cal.Rptr. 880] [concealment of defendant’s purpose is sufficient]; People v. Hyde (1985) 166 Cal.App.3d 463, 475-476 [212 Cal.Rptr. 440] [concealment of identity, defendant being disguised as policeman]; Domino v. Superior Court (1982) 129 Cal.App.3d 1000, 1007 [181 Cal.Rptr. 486] [secret design to take victim by surprise]; People v. Ward (1972) 27 Cal.App.3d 218, 230 [103 Cal.Rptr. 671] [same].) As stated in Ward, the concealment element “may manifest itself by either an ambush or by the creation of a situation where the victim is taken unawares even though he sees his murderer.” (27 Cal.App.3d at p. 230, italics added.) Thus, in Sassounian, supra, 182 Cal.App.3d 361, also involving the validity of a lying-in-wait special-circumstance finding, defendant was first observed waiting on a street corner a few minutes before the shooting, then was seen standing by the passenger side of the victim’s car while the shooting was occurring, and then seen running away with an accomplice while stuffing a gun into his pants. On appeal, the court rejected his argument that instructions on a lying-in-wait special circumstance were inappropriate because there was no evidence of any concealment prior to the shooting. As the Sassounian court explained, “concealment, in the sense that the defendant uses the term, is not required in order to justify and support a ‘lying-in-wait’ special circumstance. The concealment which is required, is that which puts the defendant in a position of advantage, from which the factfinder can infer that lying-in-wait was part of the defendant’s plan to take the victim by surprise. [Citation.] It is sufficient that a defendant’s true intent and purpose were concealed by his actions or conduct. It is not required that he be literally concealed from view before he attacks the victim. [Citations.]” (182 Cal.App.3d at pp. 406-407.) We conclude that the jury in the present case was properly instructed on the concealment element of the lying-in-wait special circumstance, and that the evidence was sufficient to support a finding of lying-in-wait murder, based on defendant’s watchful waiting, from a position of advantage in the backseat, while the car was driven to a more isolated area, and his sudden surprise attack, from behind and without warning, on victim Winchell. (See also People v. Ruiz (1988) 44 Cal.3d 589, 615 [244 Cal.Rptr. 200, 749 P.2d 854] [defendant, a family member, waited until his victims were asleep before killing them].) Defendant relies primarily on two cases which assertedly conflict with the foregoing authorities. In People v. Merkouris (1956) 46 Cal.2d 540, 559-560 [297 P.2d 999], we concluded that lying-in-wait instructions should not have been given under the circumstances in that case. There, the defendant on several prior occasions had been seen sitting in a car parked near the crime scene, but significantly he was not so observed on the day of the murder a few days later. We cited Sutic, supra, 41 Cal.2d 483, and Tuthill, supra, 31 Cal.2d 92, with apparent approval but distinguished those cases on the ground that in Merkouris, “The killings were not accomplished through defendant’s watchful waiting in his car; there was no attempt at either concealment or secrecy; and the killings did not follow on the heels of the watchful waiting.” (46 Cal.2d at p. 560.) Thus, although there was a period of watchful waiting in Merkouris, it occurred several days prior to the murders. Merkouris is thus distinguishable, for in the present case defendant’s watchful waiting occurred contemporaneously with the assault, and indeed was part of the “means” through which that assault could be accomplished. (See Tuthill, supra, 31 Cal.3d at p. 101.) Next, defendant cites Richards v. Superior Court (1983) 146 Cal.App.3d 306, 314-316 [194 Cal.Rptr. 120], to support his position that some period of physical concealment is required to sustain a lying-in-wait finding. There, the victim was stabbed to death and robbed after being lured to a garage by the defendants on the pretext that they needed to recover some of their tools. Because there was no indication as to precisely how the murder occurred, and thus no evidence that the defendants “approached the victim from physical concealment after ‘watchful waiting,’ ” the Richards court dismissed the lying-in-wait special-circumstance allegation. (Pp. 314-316.) Significantly, Richards rejected the argument that the element of concealment could be satisfied merely by taking the victim “unawares” from behind; the court observed that such a rule “would require that we equate concealment with surprise . . . .” (P. 315.) Richards is factually distinguishable, given the absence of any period of watchful waiting on the defendants’ part. They simply lured their victim to a garage and killed him. Nonetheless, the court’s insistence on some period of actual physical concealment stands in conflict with the cases, previously cited, which indicate that, if a period of watchful waiting is shown which immediately precedes the assault, a concealment of purpose, coupled with a surprise attack from a position of advantage, will satisfy the concealment element in lying-in-wait murder. We thus disapprove Richards to the extent it would require an actual physical concealment as an element of lying in wait. 2. Constitutional Considerations— Defendant suggests that our interpretation of the lying-in-wait statute as not requiring an actual physical concealment runs afoul of constitutional principles barring the arbitrary selection of certain murders as justifying the death penalty. In defendant’s view, such an interpretation would provide no meaningful basis for distinguishing capital and noncapital cases, and would thereby allow the arbitrary or irrational imposition of the death penalty. (See, e.g., People v. Rodriguez (1986) 42 Cal.3d 730, 778 [230 Cal.Rptr. 667, 726 P.2d 113]; People v. Davenport (1985) 41 Cal.3d 247, 265-266 [221 Cal.Rptr. 794, 710 P.2d 861].) Defendant assumes that, unless a physical concealment requirement is imposed, a lying-in-wait finding could be routinely made “in the case of any intentional murder in which the defendant decides to attack his victim, but waits and watches—without notifying his victim of his intent to attack— before inflicting the fatal injuries.” In defendant’s view, physical concealment adds an element of plotting “far in excess of the level of forethought required for premeditation and deliberation,” and additionally suggests “a particularly repugnant form of sneaking cowardice.” (See Richards v. Superior Court, supra, 146 Cal.App.3d 306, 314, fn. 5 [observing that in earlier times, special scorn was reserved for those whose attack after lying in wait deprived the surprised victim of the opportunity for reflection and contrition].) We reject defendant’s constitutional challenge to our interpretation of the lying-in-wait special-circumstance statute. First of all, we do not mean to suggest that a mere concealment of purpose is sufficient to establish lying in wait—many “routine” murders are accomplished by such means, and the constitutional considerations raised by defendant might well prevent treating the commission of such murders as a special circumstance justifying the death penalty. But we believe that an intentional murder, committed under circumstances which include (1) a concealment of purpose, (2) a substantial period of watching and waiting for an opportune time to act, and (3) immediately thereafter, a surprise attack on an unsuspecting victim from a position of advantage, presents a factual matrix sufficiently distinct from “ordinary” premeditated murder to justify treating it as a special circumstance. The question whether a lying-in-wait murder has occurred is often a difficult one which must be made on a case-by-case basis, scrutinizing all of the surrounding circumstances. But contrary to defendant’s argument, we conclude that an intentional murder undertaken by lying in wait in the foregoing manner is properly among the kinds of aggravated killing which justify society’s most severe penalty. 3. No Cognizable Interruption— Defendant next contends that the evidence was insufficient to show that the murder was committed while defendant was lying in wait (§ 190.2, subd. (a)(15)), that is, that the murder occurred without any “cognizable interruption” following the period of lying in wait. (See Domino v. Superior Court, supra, 129 Cal.App.3d at p. 1011.) Indeed, defendant suggests that only a “pure ambush” situation would satisfy the Domino rule. The point lacks merit. Section 189 provides that a murder “perpetrated by means of’ lying in wait is first degree murder. Section 190.2, subdivision (a)(15), however, describes the lying-in-wait special circumstance as the commission of an intentional murder “while lying in wait.” (Italics added.) Domino held that the use of the word “while” in the latter provision indicated that a closer temporal proximity was required than needed to prove mere lying-in-wait murder. As Domino stated, “the killing must take place during the period of concealment and watchful waiting or the lethal acts must begin at and flow continuously from the moment the concealment and watchful waiting ends. If a cognizable interruption separates the period of lying in wait from the period during which the killing takes place, the circumstances calling for the ultimate penalty do not exist.” (129 Cal.App.3d at p. 1011, italics added.) We need not consider the validity of Domino’s restrictive interpretation of the special circumstance provision (cf. People v. Guzman (1988) 45 Cal.3d 915, 949-952 [248 Cal.Rptr. 467, 755 P.2d 917]), because the evidence in this case clearly would support a finding that defendant’s lethal acts flowed continuously from the moment he commenced his surprise attack. Defendant, after watching and waiting until the car and its occupants reached the outskirts of town, suddenly and without prior warning attacked his victim from behind with the intent to kill her. Although victim Winchell evidently survived defendant’s initial attempt to strangle and beat her to death, no “cognizable interruption” occurred between the period of watchful waiting and the commencement of the murderous and continuous assault which ultimately caused her death. Defendant speculates that Winchell may have already been aware of his and Ortega’s murderous plans, and accordingly she was not taken by surprise. But her screams for assistance from Ortega would support a finding that she was indeed surprised by, and unprepared for, the attack. We conclude that the lying-in-wait special-circumstance finding should be sustained. 4. No Corpus Delicti— Defendant next argues that because the evidence of lying in wait was derived primarily from his own extrajudicial statements, the prosecution failed to establish the corpus delicti of the lying-in-wait special circumstance. We have recently rejected the argument that nonfelony-based special circumstances must be supported by independent proof of the corpus delicti (People v. Howard (1988) 44 Cal.3d 375, 415 [243 Cal.Rptr. 842, 749 P.2d 279]; see Newberry v. Superior Court (1985) 167 Cal.App.3d 238 [213 Cal.Rptr. 129], 241; People v. McDermand (1984) 162 Cal.App.3d 770, 798 [211 Cal.Rptr. 773] [no corpus delicti required for lying-in-wait special circumstance]), and we see no reason to reconsider our holding here. B. Torture Murder As previously indicated, the jury was instructed on three theories of first degree murder, namely, premeditation, lying in wait and torture. The jury returned a verdict of first degree murder, expressly finding that the killing was premeditated, and that the victim was “aware of extreme physical pain inflicted” by defendant, a finding from which we can infer a finding of torture murder. Additionally, the jury found true the torture-murder special-circumstance allegation. Although we need not directly confront defendant’s challenges to the jury’s torture-murder finding (because the conviction of first degree murder can be sustained on a premeditated-murder basis), a brief examination of the issues is necessary as background to our discussion of the validity of the torture-murder special-circumstance finding. 1 .Intent to Inflict Extreme Pain—In this case, the evidence indicated that victim Winchell’s death was extremely prolonged and painful. Severe pain, however, accompanies most homicides and, accordingly, we have held that murder by torture requires a premeditated intent to inflict extreme and prolonged pain. (People v. Steger (1976) 16 Cal.3d 539, 546 [128 Cal.Rptr. 161, 546 P.2d 665, 83 A.L.R.3d 1206].) The jury was so instructed in this case. An intent to inflict pain may be inferred from the circumstances of the crime, the nature of the killing, and the condition of the victim’s body. (See Steger, supra, at p. 546; see also People v. Robertson (1982) 33 Cal.3d 21, 51 [188 Cal.Rptr. 77, 655 P.2d 279]; People v. Demond (1976) 59 Cal.App.3d 574, 583-584 [130 Cal.Rptr. 590].) Steger observed that cases reversing torture-murder convictions “have focused on the lack of evidence of calculation,” a factor indicating a killing “in hot anger.” (16 Cal.3d at p. 547.) Although the evidence in the present case was somewhat ambiguous concerning defendant’s intent in this regard, it seems clear that such evidence, including the premeditated and prolonged assault, the unusually forcible strangulation attempt, the numerous hammer and stab wounds, the rape, and defendant’s earlier statement that he intended to “hurt” and strangle a girl, was sufficient to sustain the jury’s implied finding of intent to inflict extreme pain. 2. Judgment N.O.V.— Having concluded the evidence was sufficient to support a torture-murder finding, we must next consider the effect of the trial court’s limited judgment n.o.v., which purported to vacate that finding for lack of sufficient evidence of intent to torture. The trial court originally granted a new trial on this issue, later vacating that ruling in favor of a judgment n.o.v. The People have filed a cross-appeal from the judgment n.o.v., arguing that the court lacked authority to enter it. The precise sequence of events leading to the People’s appeal is as follows: Prior to the commencement of the penalty phase, defendant moved for a new trial on various grounds, including insufficiency of the evidence to establish the intent element of torture murder. The trial court granted the new trial motion only as to the jury’s implied finding of torture murder, and the penalty phase commenced. (The court, denying a new trial as to the torture-murder special-circumstance finding, mistakenly assumed that an intent to cause extreme pain was not an element of the special circumstance.) The People later moved the court to set aside its new trial order, on the basis that double jeopardy principles would bar a retrial of any murder prosecution based on torture murder. Accordingly, the court vacated its new trial order and granted a judgment n.o.v. as to the jury’s implied torture-murder finding. Following entry of the death penalty judgment, the People filed a cross-appeal from the judgment n.o.v. We agree with the People that the trial court’s purported judgment n.o.v. must be set aside. (See People v. Morgan (1977) 75 Cal.App.3d 32, 39 [141 Cal.Rptr. 863] [no judgment n.o.v. available in criminal cases].) Although Morgan suggested that such a judgment might be treated as a new trial order, the court’s order herein does not fall within any of the statutory grounds for new trial. The only ground that might apply is that the “verdict or finding” was contrary to the law or evidence (§ 1181, subd. 6). As the People observe, however, there was no “verdict or finding” which was set aside, because the court upheld the first degree murder conviction. Although the jury’s verdict may well have contained an implied finding of torture murder, we have found no case indicating that a new trial order is appropriate to annul an implied finding, especially one affecting only one of several potential theories of first degree murder. Moreover, the fact remains that the trial court vacated its new trial order on the express ground of a concern over the “double jeopardy bar,” and accordingly it would be improper to treat the judgment n.o.v. as a new trial order for purposes of sustaining the court’s judgment. We conclude that (1) the jury’s implied finding of torture murder was adequately supported by the evidence, and (2) the court lacked the authority to set aside that finding in the manner attempted here. 3. The Torture-murder Special Circumstance— Defendant correctly observes that the trial court’s instructions regarding the torture-murder special circumstance were flawed because, unlike the torture-murder instructions themselves, they failed to explain that proof of an intent to inflict extreme pain was required to sustain such a finding. (See People v. Davenport, supra, 41 Cal.3d 247, 270-271; People v. Leach (1985) 41 Cal.3d 92, 109-110 [221 Cal.Rptr. 826, 710 P.2d 893].) Instead, the jury was told only that, to establish the special circumstance, the murder must be intentional, that it involved torture, and that “[t]o prove the infliction of tortu
