Opinion KENNARD, J. Defendant Nathan Verdugo was convicted of the first degree murders of Yolanda Navarro and Richard Rodriguez. (Pen. Code, §§ 187, 189.) The jury also found true the multiple-murder special-circumstance allegation, as well as allegations that defendant personally used a firearm, i.e., a shotgun, in each crime. (§§ 190.2, subd. (a)(3), 12022.5, former subd. (a).) At the penalty phase, it returned a death verdict, and the trial court entered a judgment of death. This appeal is automatic. (Cal. Const., art. VI, § 11, subd. (a); Pen. Code, § 1239, subd. (b).) We affirm the judgment. I. Factual Background A. Guilt Phase 1. Prosecution evidence a. Events on October 22 and 23, 1994 On October 22, 1994, defendant went to a Halloween party at the home of Hector Casas in the Glassell Park neighborhood of Los Angeles. The party was well attended, and guests included Lisa Ruvalcaba, Raymond Muro, Paul Escoto, defendant’s friend Michael (Mike) Arevalo, and victims Rodriguez and Navarro. Defendant wore wire-rimmed glasses and drove a black Honda CRX, which had tinted windows and a loud exhaust system. At one point Lisa Ruvalcaba—who resembled victim Yolanda Navarro— attacked Michael Arevalo, hitting him in the face with a beer bottle. Arevalo, who was bleeding and enraged, yelled, “Fucking bitch.” He had to be restrained from retaliating by a group of approximately seven people. Someone in the group yelled, “Shoot the bitch.” Arevalo was taken to the hospital, where he received over 50 stitches. After the attack, defendant left the party and ran to his car. Raymond Muro followed. Defendant opened his trunk and showed Muro a pump-action shotgun with a pistol grip. Defendant told Muro he was going to “get that girl” or “get those people.” Muro responded, “just calm down, . . . there is no need for that.” Defendant then put the shotgun away, and he and Muro ' returned to the party. Rodriguez and Navarro left the party in Rodriguez’s burgundy Honda Civic. Another car, resembling defendant’s black Honda CRX, pulled out and followed them. About 2:00 a.m., Alex Quintana of the Los Angeles Fire Department heard voices and someone running outside the window of the fire station at Huntington Drive and Monterey Road. Firefighter Donald Jones heard an argument. Quintana then heard what sounded like a shotgun blast. About 10 seconds later he heard a second shotgun blast, and three to five seconds after that a third blast. Quintana then heard a woman “begging for her life.” She said: “No, no, please don’t do it. Please, please, don’t.” Quintana heard another shotgun blast. He looked out of the window and saw a man “standing over the girl holding a shotgun” six to 12 inches from the woman’s head. The woman was facedown, lying on her side on the sidewalk. The man inserted another round into the chamber of the shotgun, which Quintana identified by sound as a “pump action.” The man then shot the woman in the head. Firefighter Jones saw the gunman, who he said looked like defendant, run to a car with a louvered rear window. Firefighter Quintana saw a black Honda with tinted windows and a loud exhaust system “come out from around the fence and head north.” The firefighters left the station. They found two bodies: the woman whose death Quintana had witnessed (later identified as Navarro) and a man (later identified as Rodriguez). Rodriguez’s car was parked, but it was still running, with its lights on. It had sustained collision damage. About a car’s length behind this vehicle, firefighter Jones found a pair of wire-rimmed eyeglasses on the ground. The lenses in these glasses matched a prescription defendant had received about a year earlier. Also found in the area were five 12-gauge Fiocchi shotgun shells. There were skid marks behind the vehicle, and the distance between the skid marks matched the wheelbase on defendant’s Honda CRX. The marks had been made by a front-wheel-drive car such as defendant’s. The firefighters blocked the streets with their fire engines. As they did so, Jonathan Rodríguez arrived at the scene and told firefighters that he thought the deceased woman on the sidewalk was his sister. Firefighter Quintana questioned his identification because part of the woman’s face was missing. Jonathan called his mother from the fire station and asked her to page his sister. A pager lying next to the woman began vibrating. The autopsies showed that Navarro and Rodriguez died from gunshot wounds to the head, inflicted by a weapon held two to four feet away. Navarro suffered a single gunshot wound. Rodriguez suffered a gunshot wound to the head and three gunshot wounds to his foot and leg; the latter were consistent with being shot while attempting to run away. Toxicology analysis of Rodriguez’s blood did not show the presence of alcohol or drugs. Michael Arevalo was discharged from the hospital between 2:20 and 2:40 a.m. on October 23. He was taken back to Hector Casas’s house. Arevalo, Arevalo’s father, Arevalo’s father’s girlfriend, and Raymond Muro then drove to Muro’s house, which was located directly in front of Arevalo’s father’s house. As they pulled into the carport, Muro saw defendant. Muro heard defendant tell Arevalo that “the situation had been handled,” and Arevalo and defendant embraced. Defendant spent the night at Muro’s house. In the morning, defendant, Arevalo, and Muro went out to breakfast. Defendant was wearing sunglasses that were different from the wire-rimmed glasses he had worn to the party the night before. While they were at the restaurant, Arevalo’s mother arrived and spoke with Arevalo privately, telling him about the double homicide. When Arevalo returned to the table, he relayed this information to defendant and Muro. b. Defendant’s statements Donna Tucker, who was married to defendant’s brother Michael, had known defendant since he was three years old. In the summer or fall of 1993, defendant told Tucker that he and Arevalo were like brothers and that they would do anything for one another. On October 23, 1994, in the morning of the murders, defendant called Tucker, who lived about a quarter of a mile from the murder scene. Defendant excitedly asked Tucker: “Did you hear the shots in the neighborhood? My friend Mikey told me that there were shots fired in your neighborhood.” Sometime between October 23 and November 2, Tucker asked defendant to help move items out of storage to her house. Defendant refused, saying he could not “come into the area” because “[i]t was too dangerous.” Tucker testified that on November 2, 1994, defendant was working with Tucker and his brother Michael Verdugo at a construction site in Van Nuys. Tucker let defendant use the phone to return a page from his brother Paul. Paul told defendant that the police wanted to speak with him about a fight at a party. Defendant then called the police. During this telephone conversation, Tucker heard defendant say that he had left the party early and had not seen a fight. He said that he was calling from Las Vegas, where he was working on a construction site, and that he could not give his address or telephone number. Detective Andrew Teague of the Los Angeles Police Department testified about the same telephone conversation. He said that he received a call from defendant, who said he was living in Las Vegas and working for “TG&E Construction Company.” Defendant sounded nervous during the conversation and refused to give Teague his address or telephone number. After defendant completed the telephone conversation, he told Tucker that on his way to Magic Mountain he “killed two guys.” He said the homicides occurred after he left a party. Gang members chased his car and crashed into him at Huntington Drive and Monterey Road. Then a man with tattoos from “head to toe” shot at him. Defendant said he shot the man because it “was him or me.” He said there was “a girl” with the man, and he “shot her because she saw everything.” Defendant said that the police would be after him and that he was going to flee. On November 9 or 10, 1994, Tucker and defendant met so she could return some equipment from the November 2 construction job. Defendant told Tucker that he could not go to her neighborhood, so they met in a Bank of America parking lot in South Pasadena. At this meeting, defendant said that the police and the Federal Bureau of Investigation were after him, and he kept looking around. Tucker showed defendant a newspaper story about the murders. She asked him, “Is this the one you were talking about?” Defendant read the article and replied, “Yeah, that’s the one,” but he added, “that’s not the way it happened.” He then gave a description of the killings that was similar to the one he had given on November 2 and said about the killings that “he got a rush off of that, that it felt really good.” During this conversation, defendant was smiling and seemed excited. Defendant said that his brother Paul helped him get rid of his bloody clothes and the shotgun. At some point before defendant was arrested, Tucker showed him a different newspaper article about the murders and asked him if he had committed them. Defendant said he had. Tucker asked him whether he was sorry, and he said he was not. Defendant said that the firefighters “in the upper floors saw him, that his fingerprints were on the shotgun shells, [and that] they had his eyeglasses.” He also said that, contrary to what the newspaper article said, there was no traffic at the time of the murders. Defendant told Tucker that he had been in Mexico, but was forced to return when a local newspaper “show[ed] him with a beard.” Defendant then wrote a letter to his sister Pauline, which Tucker agreed to send. Defendant, who was shaking, wrote that he was sorry for what he had done, that things did not look good for him, and that he would wait to see her. Tucker subsequently received another letter that defendant had written to Pauline, postmarked April 14, 1995. In the letter, defendant said: “The [p]olice have shotgun sh[e]lls that have my prints on them and a pair of glass[es] that I have on in the photo.” He also enclosed a copy of a newspaper article about the murders. A relative of defendant’s, Juan Carlos Enciso, made a tape-recorded statement to police on December 15, 1994. This statement was played for the jury. Enciso told police that defendant had told him during the first week of November 1994 that he had recently “bl[o]w[n] away” two people. Defendant claimed there had been a chase on the freeway, that the people chasing him were shooting at him, and that he had to kill them or be killed. In addition, Detective Teague and Detective Charles Markel of the Los Angeles Police Department testified about an untaped interview with Enciso. Enciso said that defendant had told him that his Honda CRX had “crashed” during the shooting incident and that it needed to be repaired. At the time of his arrest, defendant was carrying a letter he had written to his sister Pauline, telling her to “[b]um all paper from me.” c. Other evidence linking defendant to the murders In November or December 1994, defendant, defendant’s uncle Daniel Cuevas, and defendant’s brother Paul Verdugo took defendant’s Honda CRX to a shop to be painted yellow. After the painting was completed, the shop called Cuevas four or five times, and he in turn contacted defendant’s brother Paul, but the car was never picked up. On April 15, 1995, police located and impounded the vehicle. The murder weapon was not introduced at trial, but the prosecution introduced evidence that on September 19, 1990, defendant purchased two Mossberg 12-gauge shotguns from a Big 5 Sporting Goods store. On April 16, 1992, he reported them stolen to the police. On January 17, 1993, police recovered one of the shotguns, which had a pump action, and on January 28, 1993, they released it to defendant. Defendant was arrested on April 27, 1995. He was found hiding in a secret compartment behind the linen closet in his father’s home. 2. Defense evidence Defendant testified that he was bom on September 5, 1972, and had no criminal record. He completed the 10th grade in high school. He denied murdering Navarro and Rodriguez and claimed that Raymond Muro and Paul Escoto had committed the murders. Defendant testified that in February 1994 he was stabbed, and his Honda CRX was damaged. After this incident, he began carrying a shotgun in his car. Defendant admitted that Arevalo was a good friend but, contrary to the prosecutor’s assertion, defendant denied Arevalo was as “close as being a brother” or that defendant “would do anything for him.” Although defendant had known Arevalo as a child, they had become friends less than a year before defendant was stabbed. Defendant testified that he and Arevalo attended the Halloween party on the night of the murders, at which Arevalo was hit with a bottle. Defendant was in the kitchen at the time, and Arevalo was outside. Defendant did not see Arevalo after he was hit, and defendant left the party because he did not want to get involved. He found the driver’s door to his car open and noticed that his shotgun and a jacket were missing. Also missing was a key to his vehicle, which he said he had hidden under the fender. A pair of defendant’s eyeglasses, similar to the ones he had worn that night, were in the missing jacket. Defendant testified that he had shown the hidden car key to several individuals, including Arevalo, Muro, and Escoto. Defendant stated that he returned to the party after discovering his car open and the items missing. Defendant believed that Arevalo had taken the shotgun, because Arevalo knew about the hidden key and had taken defendant’s shotgun out of the car on another occasion. In addition, he heard Arevalo shout at the party: “Fuck you, bitch. You’re going to get it.” Defendant could not locate Arevalo at the party and went to Arevalo’s father’s house looking for him. On cross-examination, defendant said that Arevalo arrived at the house shortly after defendant, accompanied by his father, his father’s girlfriend, and Muro. He said that Muro was “jittery.” Defendant spent the night at Muro’s house. He said that Muro acted nervous, could not sleep, and drank heavily. Defendant testified that later the same morning, defendant, Arevalo, and Muro went out to breakfast. Arevalo’s mother arrived, and Arevalo left the restaurant to speak with her. Defendant told Muro that he believed Arevalo had taken defendant’s shotgun, and Muro said: “No. Me and Paul did.” Muro also said he and Escoto “took care of things.” Defendant asked Muro what he meant, and Muro, who had been in the United States Marine Corps said that “his training paid off.” Defendant then said: “I don’t care what you did. I just want my gun back.” Defendant testified that he did not report the shotgun theft to law enforcement officials because he was concerned about the risk to his family. He lied to Detective Teague about being in Las Vegas, because he did not want to get involved regarding the events that had taken place at the Halloween party. He said that his family had to move after he was stabbed, implying that he lied because he did not want to go through a similar situation again. Defendant said that he was afraid Arevalo and his friends would hurt defendant and his family. Defendant testified that he fled when he learned he was a suspect in the murders. He changed his appearance, used aliases, and stayed in motels. He said that he lost the wire-rimmed glasses he had worn to the Halloween party. Defendant admitted that he lied to police during an interview after his arrest. He testified: “I’m a liar, a storyteller, but I’m not no killer.” Defendant also testified that he never got along with Donna Tucker. He said that he never spoke with Tucker and that she had lied when she testified about conversations between herself and defendant after the murders. Defendant discussed defense exhibit B, which was a pair of eyeglasses. He said that they resembled, but were not, the pair of eyeglasses that he wore to the Halloween party. Defendant explained that he asked someone to purchase the exhibit B eyeglasses while he was in jail and then falsely informed his attorney that they were the glasses he had worn to the party. He said he lied about the eyeglasses because others had lied. Defendant said: “I panicked, felt like I was being framed, no one was going to believe me, that I lost the glasses, so I had those purchased.” Mary Alice Baldwin, defendant’s sister, testified that defendant was bom in Pasadena. Their mother died in 1982, when defendant was a boy, and Baldwin, who was 15 years older than defendant, assumed a maternal role in his life. Baldwin testified that defendant had a learning disability that affected his comprehension of English and his ability to spell. Baldwin further testified that defendant told her around Thanksgiving 1994 that “Ray” and “Paul” had committed the murders after taking defendant’s shotgun. They had also threatened to kill defendant, and defendant feared they would kill his family. Baldwin further testified that defendant’s Honda CRX did not have louvers on the back window. The defense also presented expert testimony describing the effect to a human head when it receives a shotgun wound at close range. 3. Prosecution rebuttal evidence Mary Alice Baldwin, defendant’s sister, testified about statements defendant had made to her, which she had earlier related to detectives. Defendant had told her of a time when he was driving home on the Long Beach Freeway and “they were shooting at me.” Defendant had told her that he tried to get away. Detective Markel testified about a telephone conversation he had with Baldwin on May 23, 1995, in which she described the statements defendant had made to her. Baldwin told Markel that she had seen defendant about a month earlier. At that time, defendant told her about a time when he was going home on the Long Beach Freeway and certain individuals shot at him and it was either “him or me.” Detective Teague testified that louvers could be applied to the rear window of a car, either by drilling holes into the metal of the vehicle or by using double-sided adhesive. The latter method allowed the louvers to be easily removed, and the glue also could be removed with a solvent. B. Penalty Phase 1. Prosecution evidence Relatives of the victims testified about the effect the murders had on their lives. The jury heard testimony from Rodriguez’s mother, two cousins, and his aunt and uncle, and also from Navarro’s mother, sister, and brother. 2. Defense evidence William Wright testified that he and defendant had been friends for about 23 years. He met defendant when defendant was between five and seven years old, at which time Wright was 17 or 18 years old. As a child, defendant was quiet, very respectful, and industrious. He was also extremely close to his family. Wright had never seen defendant bully anyone or known him to be violent. Wright did not know any of the details of defendant’s crimes. He offered his opinion that prosecution witness Donna Tucker was not a credible person. He also testified that, if defendant were allowed to live, he would be productive in prison. Michael Verdugo, defendant’s brother, testified that he was 12 to 13 years older than defendant. He and defendant were close, as was defendant to other family members. Michael stated that defendant worked for him on construction sites. Defendant followed directions well and was good with his hands. Michael also said that defendant avoided criminal street gangs. Mary Alice Baldwin, defendant’s sister, testified that she was 23 and defendant was seven when their mother died. After his mother’s death, defendant became quieter and grew closer to Mary Alice. She testified that defendant had difficulty understanding his schoolwork and, in particular, learning to spell. She also stated that defendant was always very helpful, loving, and friendly. She did not believe he was guilty of the murders. II. Discussion A. Guilt Phase Issues 1. Denial of Keenan counsel Defendant, who was represented by retained counsel, contends that the trial court erred under state law by refusing to appoint Keenan counsel and that the error violated his rights under the Fifth, Sixth, Eighth, and Fourteenth Amendments to the federal Constitution, and article I, sections 7 and 15 through 17, of the California Constitution. (See Keenan v. Superior Court (1982) 31 Cal.3d 424, 430 [180 Cal.Rptr. 489, 640 P.2d 108] (Keenan) [trial court has discretion under statutes governing appointment of counsel to appoint a second attorney to assist in the defense of a capital case].) We disagree. Defendant was represented by retained counsel George Hernandez. Before trial, he filed a confidential application for Robert Beswick to be appointed as second counsel under section 987, subdivision (d). The trial court denied the motion for second counsel, stating (1) that “[t]here is nothing presented to this Court that would indicate the agreement between defendant and counsel was for anything less than full representation of the defendant during all proceedings,” and (2) that Hernandez’s declaration was “insufficient” in that “[t]here appear to be neither specific facts nor complexity of issues that require such appointment.” Section 987, subdivision (d), provides in relevant part: “In a capital case, the court may appoint an additional attorney as a cocounsel upon a written request of the first attorney appointed. The request shall be supported by an affidavit of the first attorney setting forth in detail the reasons why a second attorney should be appointed.” Even assuming without deciding that section 987, subdivision (d), authorized the trial court here to appoint second counsel, the trial court did not abuse its discretion in finding Defense Counsel Hernandez’s declaration insufficient to justify such an appointment. “ ‘The initial burden ... is on the defendant to present a specific factual showing as to why the appointment of a second attorney is necessary to his defense against the capital charges.’ (People v. Lucky (1988) 45 Cal.3d 259, 279 [247 Cal.Rptr. 1, 753 P.2d 1052].) An ‘abstract assertion’ regarding the burden on defense counsel ‘cannot be used as a substitute for a showing of genuine need.’ (Id. at p. 280; People v. Jackson (1980) 28 Cal.3d 264, 287 [168 Cal.Rptr. 603, 618 P.2d 149] [no abuse of discretion in denying application for second counsel when counsel merely relied on the circumstances surrounding the case].)” (People v. Staten (2000) 24 Cal.4th 434, 447 [101 Cal.Rptr.2d 213, 11 P.3d 968] (Staten).) In addition, “ ‘[t]he appointment of a second counsel in a capital case is not an absolute right protected by either the state or the federal Constitution.’ ” (People v. Lancaster (2007) 41 Cal.4th 50, 71 [58 Cal.Rptr.3d 608, 158 P.3d 157].) We review the trial court’s decision denying a request to appoint second counsel for abuse of discretion. (People v. Roldan (2005) 35 Cal.4th 646, 688 [27 Cal.Rptr.3d 360, 110 P.3d 289] (Roldan).) Here, in his declaration, Hernandez stated that the “facts and issues involved in this case are sufficiently complex to necessitate the appointment of second counsel,” that counsel anticipated “many lengthy pre-trial motions, hearings and writs,” that investigation of the guilt phase would cover “an extensive period extending both before and after the date of the crime,” that the penalty issues were “highly involved and complex” and that investigation into these issues should “be commenced without delay.” Hernandez also specifically requested the appointment of Robert Beswick, whose “defense talents complement my skills, ... his strengths offset my weaknesses, and ... his perceptions of evidence and tactics are sufficiently divergent from my own to provide both a broader and more objective viewpoint from which to make defense decisions and to formulate trial strategy.” Counsel’s declaration did not, however, provide any specific information justifying appointment of second counsel. Thus, unlike in Keenan, on which defendant relies, counsel did not state that he needed to interview more than 100 witnesses, that the case involved complicated scientific and psychiatric testimony, that trial would occur soon after counsel was appointed, or that other criminal cases were pending against defendant and that the prosecution intended to rely on evidence related to those cases here. (See Keenan, supra, 31 Cal.3d at pp. 432-434.) Rather, counsel’s declaration is comparable to those we have found inadequate in other cases. (See, e.g., Staten, supra, 24 Cal.4th at p. 447 [the defendant’s application consisted of “little more than a bare assertion that second counsel was necessary” and “presented no specific, compelling reasons”].) Nor does our review of the record substantiate defendant’s assertion that the case “was extremely complex.” Defendant further contends that he was prejudiced by the denial of his application for appointment of second counsel, because “the instant case was trial counsel’s first capital trial” and counsel “lacked the ability to properly object or to conform his conduct to that expected of capital counsel, as evidenced by the innumerable reprimands and sanctions imposed by the trial court.” To the extent defendant is arguing that the inexperience of retained counsel in trying capital cases is a sufficient reason for appointment of second counsel, this argument was not presented to the trial court, and hence cannot be raised on appeal. (Roldan, supra, 35 Cal.4th at p. 688, fn. 13.) 2. Alleged failure to disclose Brady and section 1054.1 material Defendant contends that the prosecution engaged in prejudicial misconduct by failing to disclose material it was required to provide to the defense under Brady v. Maryland (1963) 373 U.S. 83 [10 L.Ed.2d 215, 83 S.Ct. 1194] (Brady) and section 1054.1. Defendant asserts a violation of his rights under the Fifth, Sixth, Eighth, and Fourteenth Amendments to the federal Constitution, article I, sections 7 and 15 through 17, of the California Constitution, and state statutory rights. We disagree. “Pursuant to Brady, supra, 373 U.S. 83, the prosecution must disclose material exculpatory evidence whether the defendant makes a specific request (id. at p. 87 . . .), a general request, or none at all . . . .” (In re Brown (1998) 17 Cal.4th 873, 879 [72 Cal.Rptr.2d 698, 952 P.2d 715].) “For Brady purposes, evidence is favorable if it helps the defense or hurts the prosecution, as by impeaching a prosecution witness. [Citations.] Evidence is material if there is a reasonable probability its disclosure would have altered the trial result. [Citation.] Materiality includes consideration of the effect of the nondisclosure on defense investigations and trial strategies. [Citations.] Because a constitutional violation occurs only if the suppressed evidence was material by these standards, a finding that Brady was not satisfied is reversible without need for further harmless-error review. [Citation.]” (People v. Zambrano (2007) 41 Cal.4th 1082, 1132-1133 [63 Cal.Rptr.3d 297, 163 P.3d 4] (Zambrano); see also Cone v. Bell (2009) 556 U.S._, - [173 L.Ed.2d 701, 129 S.Ct. 1769, 1782-1783].) Section 1054.1 (the reciprocal-discovery statute) “independently requires the prosecution to disclose to the defense . . . certain categories of evidence ‘in the possession of the prosecuting attorney or [known by] the prosecuting attorney ... to be in the possession of the investigating agencies.’ ” (Zambrano, supra, 41 Cal.4th at p. 1133.) Evidence subject to disclosure includes “[statements of all defendants” (§ 1054.1, subd. (b)), “[a]ll relevant real evidence seized or obtained as a part of the investigation of the offenses charged” {id., subd. (c)), any “[Relevant written or recorded statements of witnesses or reports of the statements of witnesses whom the prosecutor intends to call at the trial, including any reports or statements of experts” {id., subd. (f)), and “[a]ny exculpatory evidence” (id., subd. (e)). “Absent good cause, such evidence must be disclosed at least 30 days before trial, or immediately if discovered or obtained within 30 days of trial. (§ 1054.7.)” (Zambrano, at p. 1133.) Upon a showing both that the defense complied with the informal discovery procedures provided by the statute, and that the prosecutor has not complied with section 1054.1, a trial court “may make any order necessary to enforce the provisions” of the statute, “including, but not limited to, immediate disclosure, . . . continuance of the matter, or any other lawful order.” (§ 1054.5, subd. (b).) The court may also “advise the jury of any failure or refusal to disclose and of any untimely disclosure.” (Ibid.) A violation of section 1054.1 is subject to the harmless-error standard set forth in People v. Watson (1956) 46 Cal.2d 818, 836 [299 P.2d 243]. (Zambrano, supra, 41 Cal.4th at p. 1135, fn. 13.) a. Prosecutor’s notes regarding Raymond Muro interview (1) Factual background Raymond Muro testified that after the Halloween party, he went home with Arevalo, Arevalo’s father, and Arevalo’s father’s girlfriend. As they pulled into a carport by Muro’s house, Muro saw defendant. Arevalo and defendant had a conversation. Without objection, Muro testified that defendant told Arevalo that “the situation had been handled” and that Arevalo and defendant embraced. After a recess, defense counsel informed the court that he had spoken to the prosecutor about Muro’s testimony, asking if defendant’s statement “the situation had been handled” was in a written report. The prosecutor told the court that his interview with Muro had taken place a few months earlier and that he had told defense counsel about the statement at that time, either in court or in a telephone conversation. The prosecutor said, “I told him that the only thing different that I recall from the interview was this new statement.” The prosecutor added that “the only notes taken of the interview were notes that I took myself that I have combined with questions that I have been asking the witness in court.” The trial court ordered the prosecutor to give defense counsel a copy of these notes, after redacting any attorney work product. The prosecutor agreed to do so. Defense counsel suggested that the court had a “couple of remedies” for the discovery violation, one of which was to strike the statement. The court said it did not see any harm to defendant from failure to disclose the notes, because the prosecutor had told defense counsel the substance of the statement. Defense counsel said: “[H]e may have, your honor. ... I don’t know if he has anything in his notes where he told me that.” The court found no discovery violation, but the court offered to recess until the following afternoon, so that defense counsel would have additional time to prepare for cross-examination. Trial counsel responded, “Short of the court striking the testimony, I would appreciate that very much, your honor.” (2) Analysis We first conclude that there was no Brady violation. As defendant acknowledges, the statement by defendant that “the situation had been handled” was “exceedingly damaging” to his case. Hence, it was not favorable to the defense and did not fall within the scope of Brady, supra, 373 U.S. at page 87. In addition, Muro testified to the statement. “[E]vidence that is presented at trial is not considered suppressed, regardless of whether or not it had previously been disclosed during discovery.” (People v. Morrison (2004) 34 Cal.4th 698, 715 [21 Cal.Rptr.3d 682, 101 P.3d 568] (Morrison).) Nor does defendant demonstrate prejudice from the prosecutor’s violation of section 1054.1. (See Thompson v. Superior Court (1997) 53 Cal.App.4th 480, 485-486, 488 [61 Cal.Rptr.2d 785] [written notes of an interview with an intended trial witness, other than attorney work product, are discoverable as “statements” within the meaning of §§ 1054.1, subd. (f), 1054.3, subd. (a)]; § 1054.7.) The trial court found that the prosecutor told defense counsel about the substance of the statement at the time that it was made. In addition, the trial court stopped the prosecutor’s direct examination of Muro and granted a continuance in the proceedings, thus giving defense counsel additional time to prepare for cross-examination. This continuance appears to have been more than adequate to remedy the violation of the discovery statute, and defendant does not attempt to demonstrate otherwise. Defendant asserts that the “only appropriate sanction would have been to strike the statement,” because “[b]y allowing the statement to remain, the trial court perpetuated the great prejudice caused by the statement.” Without elaboration, defendant also asserts that he “could not properly or effectively prepare for cross-examination of witnesses,” that “his ability to impeach the witness[] was adversely impacted,” and that “[tjimely disclosure of the information would have enabled counsel to adjust his theory of the case to fit the facts.” Such generalized statements are insufficient to demonstrate prejudice. Defendant does not explain what counsel would have done differently if the notes had been disclosed sooner. b. Prosecutor’s notes regarding John Hernandez interview (1) Factual background John Hernandez testified that defendant visited his house in November or December of 1994. After defendant left, Hernandez was stopped on the street by the police and questioned. Hernandez also testified that, when he was interviewed by the prosecutor, the prosecutor took notes. At a sidebar conference, the prosecutor denied taking notes of the interview. The morning after Hernandez’s testimony, the prosecutor told defense counsel that he had in fact taken notes of the Hernandez interview. The notes referred to Hernandez’s arrests for felony driving while under the influence and assault on a police officer, his employer’s telephone number, and a comment by Hernandez that licensed professionals are liars. Hernandez had also told tfie prosecutor that he had been not only arrested for driving under the influence, but also convicted of that offense, but the prosecutor was not certain this additional information was in the notes. Defendant moved for a mistrial based on the prosecution’s previous representation that he had not taken notes of this interview. The court implicitly denied the motion, stating that the proper sanction was to allow defendant to call Hernandez back to testify further. Hernandez was not recalled. (2) Analysis First, we find no Brady violation. There was no reasonable probability that disclosure of the information in the notes “would have altered the trial result” (Zambrano, supra, 41 Cal.4th at p. 1132), and therefore the notes were not “material” for purposes of Brady disclosure. The testimony that defendant was at Hernandez’s house was apparently introduced by the prosecution to demonstrate that defendant had fled. Even assuming Hernandez could have been impeached with the information in the notes, there was overwhelming evidence, including defendant’s own statements, that he fled. Moreover, the information was disclosed at trial, and hence was not suppressed for Brady purposes. (Morrison, supra, 34 Cal.4th at p. 715.) Second, we reject defendant’s assertion that the proper sanction for the statutory discovery violation was a declaration of mistrial. Defendant fails to demonstrate why the opportunity to re-call Hernandez for further cross-examination did not cure any harm. c. Donna Tucker’s oral statement that she was threatened At a sidebar conference during the trial, the prosecutor represented that Detective Teague would testify that the Verdugo family had threatened Donna Tucker’s life. Defendant objected that Tucker’s oral statement to Teague should have been disclosed to the defense. The trial court ruled that oral statements not made by a defendant did not need to be disclosed. On hearsay grounds, the court barred Detective Teague from testifying about Tucker’s statement, but the court permitted Tucker to testify about any threats made against her. Nearly a week later, Tucker testified that Salvador Verdugo, defendant’s father, had threatened her, urging her to “keep quiet.” To the extent defendant contends that failure to disclose Tucker’s oral statement to Detective Teague violated Brady, it is not clear such evidence was favorable to the defense. The fact that defendant’s family threatened Tucker hardly proves defendant’s innocence. Defendant argues that the evidence went to Tucker’s credibility, which is true, but it tended to show that Tucker might have a reason to minimize defendant’s culpability, not a reason to exaggerate his culpability. It is hard to see how the defense could have used this evidence to its advantage. In any event, the statement was disclosed at trial, and hence was not suppressed for Brady purposes. (Morrison, supra, 34 Cal.4th at p. 715.) We need not decide whether oral statements that are neither made by a defendant nor exculpatory must be disclosed under section 1054.1, subdivision (f), because, even assuming a discovery violation, defendant fails to demonstrate prejudice. Tucker did not testify concerning any threat against her until nearly a week later. Therefore, defense counsel had ample time to prepare a cross-examination of Tucker on this point. Defendant does not state specifically what counsel would have done differently if Tucker’s oral statement had been disclosed sooner. d. Prosecutor’s notes regarding Donna Tucker’s statements Firefighter Donald Jones testified that he saw the killer run to a car that had louvers on the rear window. When defendant’s Honda CRX was recovered by police in April 1995, it did not have louvers. Donna Tucker testified that defendant had past experience doing minor bodywork on cars and that before the double homicide his Honda CRX had louvers on the rear window. At a sidebar conference, defense counsel stated that the prosecution had not met its disclosure obligations with respect to Tucker’s statements. That morning, the prosecutor had given defense counsel notes of an interview conducted with Tucker about a week earlier. The notes included the phrase “louvers on windows.” The trial court found the discovery violation “trivial,” although “unprofessional.” It denied defendant’s motion for a mistrial, but invited defense counsel to file a motion for a continuance. It further observed that it would allow Tucker to be re-called for further cross-examination regarding the louvers if defendant’s investigation uncovered additional evidence. Defendant concedes the evidence was not favorable to the defense. Therefore, he cannot establish a Brady violation. There was, however, a violation of the reciprocal-discovery statute, under which the prosecutor was required to immediately disclose his notes regarding Tucker’s statement. (§§ 1054.1, subd. (f), 1054.7.) Nevertheless, no prejudice is apparent. The trial court permitted defendant to move for a continuance and, if necessary, to re-call Tucker for further cross-examination. Defendant does not explain why these remedies were inadequate. e. Disclosure of Donna Tucker’s relocation After trial, the prosecutor disclosed that his office had assisted Donna Tucker in relocating to a new home, including paying some of Tucker’s rent. In a new trial motion, defendant unsuccessfully argued that the prosecutor’s posttrial disclosure of this assistance violated Brady. He renews that contention here. In January 1996, before trial began, Kevin McCormick, the former prosecutor on the case, sought and received an ex parte order for relocation expenses for Donna Tucker not to exceed $1,318. In a declaration in support of the motion, McCormick stated that “Abe Verdugo, the defendants] uncle told Ms. [Tucker], prior to the defendant being arrested, that he knew someone was ‘snitching’ and he would take care of it when he found out who it was.” The declaration also stated that Abe Verdugo began carrying a handgun shortly after defendant was profiled on a television program for wanted criminals. Tucker testified at the preliminary hearing, which was attended by Abe Verdugo and other members of the Verdugo family. McCormick’s declaration further stated: “[D]efendant maintains [an] alliance with a local criminal street gang. Ms. [Tucker] is fearful of the associates of the defendant who know not only her, but also her family and friends.” The declaration continued: “Donna [Tucker] has sought to move out of town under an assumed name but has had difficulty due to financial restraints, local job responsibilities and the reluctance of apartment managers to permit relocation under a name other than her own. Ms. [Tucker] remains fearful of being seriously injured by associates of the defendant or his relatives as a result of coming forward with critical information in this case.” At the hearing on defendant’s new trial motion, McCormick confirmed that Tucker had told him she was fearful that defendant would have her killed if she did not move to a new location. No Brady error is apparent. Defendant contends the information was favorable to the defense to the extent it could have been used to undermine Tucker’s credibility (by demonstrating the benefits she was receiving for her cooperation with the prosecution). Whether the information, as a whole, was favorable to defendant is far from clear. But even assuming some of the information (such as the financial assistance Tucker received), in isolation, could be considered favorable to defendant, there is no “reasonable probability its disclosure would have altered the trial result.” (Zambrano, supra, 41 Cal.4th at p. 1132.) If the defense had attempted to present this evidence at trial in an effort to undermine Tucker’s credibility, the prosecution would have been entitled to present evidence explaining the reasons for Tucker’s relocation, which were that a member of the Verdugo family had threatened her, that she was fearful that defendant would have her killed unless she moved, and that defendant had ties to a criminal street gang. This rebuttal evidence would have effectively countered the defense assertion that Tucker was benefiting from her cooperation with the prosecution. In fact, Tucker’s willingness to testify against defendant despite justifiable concerns about her safety arguably would have enhanced her credibility. For the same reason, defendant fails to demonstrate prejudice from violation of the reciprocal-discovery statute. f. Disclosure of Detective Teague’s oral statement as to the direction the shooter was facing (1) Factual background On cross-examination of Detective Teague at trial, defense counsel asked what direction the assailant was facing when he shot Navarro. Teague replied, “I believe that the shooter was standing near the curb facing the fire station.” Counsel then asked if Teague had ever written a report that included that opinion. Teague replied, “I don’t believe I ever used those exact terms, no, sir.” Nevertheless, Teague believed that he had orally informed the district attorney of his opinion in December 1994. Later, outside the presence of the jury, defense counsel asserted that before Teague’s testimony, “everything that we had before us” indicated “that the shooter was facing away from” the firefighters. He further asserted that the prosecutor’s failure to disclose Teague’s oral statement violated section 1054.1, and he sought a mistrial based on prosecutorial misconduct. The trial court found no discovery violation, but said that, “assuming there is some violation here,” he would allow the defense to re-call Teague for further cross-examination on the issue. The court also observed that the defense would have three to four days, including a weekend, to consult with an expert before the prosecution completed its case-in-chief. The court said: “[I]f there is really a problem here, . . . then I’ll let you revisit it.” (2) Analysis We find no Brady violation. Defendant does not explain how Teague’s opinion about the direction the shooter was facing was favorable to the defense. (Zambrano, supra, 41 Cal.4th at p. 1132.) Moreover, Teague’s opinion was disclosed at trial, and hence was not suppressed for Brady purposes. (Morrison, supra, 34 Cal.4th at p. 715.) Nor was there prejudice from any reciprocal-discovery statute violation. Defendant does not explain why the trial court’s remedy of allowing the defense to re-call Teague for further cross-examination was inadequate. g. Disclosure of notes recording the measurement of Paul Escoto’s car (1) Factual background The defense contended that Paul Escoto, who had a car similar in certain respects to defendant’s car, could have been the shooter. On June 6, 1997, Detective Teague testified that he believed marks on the street at the murder scene were acceleration marks created by a front-wheel-drive vehicle. Defendant’s Honda CRX was a front-wheel-drive vehicle, but Teague could not recall if he had ever examined Escoto’s car to determine whether it also was a front-wheel-drive vehicle. On June 10, 1997, Detective Markel testified that the acceleration marks on the street at the murder scene measured four feet nine inches apart, matching the wheelbase of the front wheels on defendant’s car. Detective Teague testified that on June 7 he examined Escoto’s car and determined that it was a rear-wheel-drive vehicle with a wheelbase of four feet six inches. At a sidebar conference, the defense argued that the prosecution had failed to disclose Teague’s notes recording the measurements of Escoto’s car. The prosecutor said that he had received Teague’s notes that morning and had left a copy of the notes on defense counsel’s table in the courtroom “right when we walked in.” Defense counsel was unaware the notes were there. The court stated that it did not know how the prosecutor could have produced the notes to the defense any sooner than he had, but the court further stated that defendant would be permitted to defer cross-examination of Teague on this issue. Defendant moved for a mistrial, which the trial court denied. (2) Analysis No Brady error occurred, because Teague’s measurements of Escoto’s car were not favorable to the defense and were disclosed at trial. (Zambrano, supra, 41 Cal.4th at p. 1132; Morrison, supra, 34 Cal.4th at p. 715.) Nor was there any violation of the reciprocal-discovery statute. The prosecutor produced the notes to the defense the same morning that he received them, which satisfies the statutory requirement of immediate disclosure of materials that become known during trial. (§ 1054.7; see People v. DePriest (2007) 42 Cal.4th 1, 37-38 [63 Cal.Rptr.3d 896, 163 P.3d 896] [disclosure of evidence the morning after its discovery was timely under § 1054.7].) Although defendant claims he was “taken by surprise and . . . unable to effectively counter this new evidence,” the prosecution had no duty to obtain the evidence sooner than it did. (Cf. In re Littlefield (1993) 5 Cal.4th 122, 135 [19 Cal.Rptr.2d 248, 851 P.2d 42].) h. Disclosure of Detective Walton’s opinion (1) Factual background On May 30, 1997, Los Angeles Police Detective Charles Walton (who had been involved in the investigation of defendant’s case) was sitting on a bench in the hallway outside the courtroom. He was greeted by Defense Attorney George Hernandez, with whom he was acquainted. Hernandez asked Walton about paint transfer on the victim’s car and said: “[I]t looks white so it would seem that it came from a white car.” Walton replied that counsel’s assessment “was possible, but that it could have come from any color car or it could have just been the wax or lacquer transfer from the outer coating, protective coating, of a vehicle or any number of colors which may have changed color due to heat and friction of the vehicles rubbing together during the traffic collision.” On June 2, 1997, the court held a hearing outside the presence of the jury to determine whether any discovery violation had occurred in connection with Walton’s opinion about paint transfer. Detective Walton testified to the circumstances of his May 30 encounter with defense counsel recounted above. Walton also testified that as part of the investigation of the case, he had examined and made certain measurements of Rodriguez’s burgundy Honda Civic and defendant’s Honda CRX. He noticed a “whitish color” mark on Rodriguez’s Civic and mentioned it to Detective Markel. Markel said: “Don’t worry about any paint transfer. We’re not interested in that [because] the other car [was] painted after the . . . alleged accident.” Walton testified that he wrote a report summarizing his findings, but the report did not include any conclusions regarding the white mark. Walton also testified that he was “not a paint expert.” He agreed with defense counsel that the white mark he saw could have been a paint transfer, but he also agreed with the court that he was not sure. The trial court found no discovery violation, because Walton was not qualified to be a paint expert. (2) Analysis Defendant contends that if Detective Walton’s opinion regarding the white mark on Rodriguez’s Civic had been disclosed in a timely manner, defendant might have been able to locate an expert who would have testified that the mark was white paint from a white car. This testimony would have undermined the prosecution’s assertion that there was a collision between defendant’s car and the victim’s car shortly before the murders. We disagree. Before Walton’s discussion with defense counsel, the only statement Walton made about the white mark (orally or in writing) was his comment to Detective Markel that the mark existed. Defense counsel knew, however, long before his hallway conversation with Walton that the mark existed. In his opening statement, defense counsel mentioned the mark and argued that this mark was evidence that defendant’s car, which was black at the time of the murder, was not at the murder scene. Nothing prevented defense counsel from retaining an expert to support this argument. Walton’s later statement to defense counsel that the white mark might have come from a car of any color did not prevent defense counsel from continuing to argue the opposite. Walton was neither an expert regarding paint transfer, nor did he testify before the jury regarding the source of the mark. And, in any case, the prosecution cannot be faulted for failing to disclose Walton’s nonexpert opinion about the white mark, because there is no evidence that the prosecution knew Walton’s opinion. “ ‘Although the prosecution may not withhold favorable and material evidence from the defense, neither does it have the duty to conduct the defendant’s investigation for him.’ ” (Zambrano, supra, 41 Cal.4th at p. 1134.) Accordingly, we conclude there was no Brady or reciprocal-discovery statute violation. i. Disclosure of expert opinion regarding alleged collision between defendant’s and victim’s vehicles In addition to testifying outside the presence of the jury, Detective Walton also testified before the jury as an expert on accident reconstruction. He stated that he had inspected both defendant’s Honda CRX and Rodriguez’s Honda Civic. As relevant here, he concluded that bodywork had been performed on the CRX. Defendant moved for a mistrial, contending that the prosecutor failed to disclose Walton’s opinion, and therefore his testimony caught the defense by surprise. On the night before Walton’s testimony the prosecutor discussed certain photographs of defendant’s car—which had years earlier been provided to the defense—with Walton, and the next morning the prosecutor did not disclose Walton’s opinion regarding the photographs to the defense. On that limited basis, the trial court found a discovery violation, but it implicitly denied defendant’s mistrial motion. Instead, it offered to allow the defense to defer cross-examination of Walton so that the defense could consult an expert. Defendant states that “Walton’s opinions bolstered the prosecution’s claim that [defendant’s] CRX was probably the vehicle with which the victim’s red car collided.” (Italics added.) Because defendant concedes that Walton’s opinion was not favorable to the defense, there was no violation of Brady. (Zambrano, supra, 41 Cal.4th at p. 1132.) In addition, the evidence was disclosed at trial, and hence was not suppressed for Brady purposes. (Morrison, supra, 34 Cal.4th at p. 715.) With regard to the reciprocal-discovery statute, the violation did not prejudice defendant. Defendant makes no attempt to demonstrate, as he must, why the trial court’s remedy of deferring cross-examination of Walton was inadequate. j. Cumulative prejudice Defendant contends that even if a single failure to disclose evidence does not warrant reversal, the “cumulative prejudice resulting from the prosecution’s consistent course of withholding material evidence certainly does.” We have concluded that the individual discovery violations were harmless or that any harm could have been fully cured by the remedy the trial court offered. We are troubled by the number of statutory discovery violations that occurred here but, because the harm in each case was nonexistent or could have been fully avoided, we see no possibility of cumulative prejudice. 3. Evidentiary issues a. Exclusion of evidence regarding allegations that detectives had fabricated evidence in a different case Defendant contends that the trial court prejudicially erred by excluding evidence that detectives involved in his case had been accused of fabricating evidence in a different case. These detectives were exonerated, but defendant asserts that this evidence would have established the motivation for his own fabrication of evidence. Defendant claims violation of his rights under the Fifth, Sixth, Eighth, and Fourteenth Amendments to the federal Constitution, and article I, sections 7, 15 through 17, and 28, of the California Constitution. We disagree. About nine months before trial, the prosecutor informed the trial court and defensé counsel that, in a different case, Detectives Teague and Markel had been exonerated of charges that they had fabricated evidence. At trial in this case, defense counsel sought permission to present evidence regarding the investigation of Detectives Teague and Markel. Counsel asserted that this evidence would substantiate defendant’s explanation for why he had arranged from jail to have a pair of eyeglasses purchased that matched the eyeglasses he wore to the Halloween party. Defendant claimed that he did so because he believed Detectives Teague and Markel were falsely accusing him, and he wanted to refute their false accusations with false evidence of his own. Defense counsel implied that such a motivation would negate any argument that defendant arranged the purchase of the eyeglasses because of a consciousness of guilt. The trial court pointed out that, as of that time, the evidence related to the purchase of the eyeglasses demonstrated only that defendant’s brother and father had fabricated evidence; no evidence tied defendant to their activity. The court said it would instruct the jury that the evidence regarding the purchase of the eyeglasses could not be considered against defendant, and could only be used for purposes of considering the credibility of Salvador and Paul Verdugo. The court excluded the evidence regarding the investigation of Detectives Teague and Markel, finding the probative value of that evidence substantially outweighed by the consumption of time and the distraction of exploring a collateral issue. (Evid. Code, § 352.) No abuse of discretion appears. (People v. Farley (2009) 46 Cal.4th 1053, 1129 [96 Cal.Rptr.3d 191, 210 P.3d 361] (Farley).) Even assuming that the evidence of the allegations against Detectives Teague and Markel was relevant, the trial court reasonably excluded it under Evidence Code section 352. This is especially so considering that the detectives had been exonerated of fabricating evidence by the time defendant’s trial began and the prosecution would then have been entitled to bring that point to the attention of the jury. The result would have been a lengthy evidentiary detour into a matter that was only marginally relevant and might well have confused the jury. Defendant later testified that he lied to his attorney about the eyeglasses his brother and father had obtained (claiming they were the same eyeglasses he had worn to the Halloween party) to counter the lies of Donna Tucker and Detective Teague. Defendant said: “I panicked, felt like I was being framed, no one was going to believe me, that I lost the glasses, so I had those purchased.” Thus, the jury heard defendant’s explanation for why he arranged for the purchase of the glasses; the additional evidence that Detectives Teague and Markel had been accused of, and exonerated of, fabricating evidence in an unrelated case would have done little to substantiate this explanation. b. Exclusion of evidence of Donna Tucker’s need for psychiatric care Defendant contends the trial court erred when it precluded defendant from presenting evidence that Donna Tucker had received psychiatric care. We disagree. (1) Factual background As noted, Donna Tucker, who was married to defendant’s brother Michael Verdugo, testified for the prosecution. Between the time of the murders and the time of trial, Tucker and Michael divorced. The defense case included an effort to discredit Tucker. On direct examination, defendant’s sister, Mary Alice Baldwin, testified that she had known Tucker since 1973. Defense counsel asked, “Did you ever think that Donna was not mentally stable?” The trial court sustained the prosecutor’s relevance objection. Defense counsel then inquired, “Well, from your observations, did you ever see anything about her that you thought was unusual?” The trial court again sustained the prosecutor’s relevance objection. At a sidebar conference, defense counsel asserted that Tucker had been admitted to a psychiatric hospital approximately three months earlier. Counsel said he had learned this information the night before from Michael Verdugo, who said he was “paying the psychiatric bills and hospital bills as part of the divorce settlement.” The prosecutor told the court that he had no knowledge regarding these assertions. The trial court observed that receipt of psychiatric care “does not necessarily reflect on” credibility and that counseling is common for individuals who are going through a divorce. Defense counsel sought permission to question Baldwin as to whether Tucker had had any previous episodes of unusual laughing and crying, noting that Tucker had laughed and cried during her testimony. The court found the evidence would require a collateral inquiry into the circumstances under which Tucker had previously laughed and cried. It also found the evidence irrelevant, because Baldwin was not an expert on mental health and not qualified to give an opinion as to whether the laughing and crying was an expression of normal emotion or a sign of mental illness. The court noted that Tucker’s hospital bills “could be some kind of outpatient counseling for the stress of the divorce” and concluded: “[A]s you present it to me right now, it’s too vague and general. You’re going to have to get specific with a witness that’s qualified. That’s all I’m telling you.” (2) Analysis “[T]he mental illness or emotional instability of a witness can be relevant on the issue of credibility ... if such illness affects the witness’s ability to perceive, recall or describe the events in question.” (People v. Gurule (2002) 28 Cal.4th 557, 591-592 [123 Cal.Rptr.2d 345, 51 P.3d 224].) Here, however, there was no evidence Baldwin was
