COURT OF APPEAL, FOURTH APPELLATE DISTRICT

DIVISION ONE

STATE OF CALIFORNIA

THE PEOPLE, D085005

Plaintiff and Respondent,

v. (Super. Ct. No. SCD291807)

JAMAR COOK, Jr.,

Defendant and Appellant.

APPEAL from a judgment of the Superior Court of San Diego County, Steven E. Stone, Judge. Affirmed. Arthur Martin, under appointment by the Court of Appeal, for Defendant and Appellant. Rob Bonta, Attorney General, Charles C. Ragland, Chief Assistant Attorney General, Arlene A. Sevidal, Assistant Attorney General, Collette C. Cavalier, and Tami Falkenstein Hennick, Deputy Attorneys General, for Plaintiff and Respondent. I INTRODUCTION Jamar Cook, Jr. appeals a judgment of conviction after a jury found him guilty of first degree murder, five counts of attempted murder, and other crimes arising out of a gang-motivated drive-by shooting. He contends the trial court erred by admitting into evidence certain recorded statements he made to a covert law enforcement agent during an undercover jailcell operation. He asserts the statements were inadmissible because law enforcement procured the statements from him after he had invoked his right to remain silent and his right to counsel, thus violating his rights under the Fifth and Fourteenth Amendments to the United States Constitution. Alternatively, he claims his substantive due process rights were violated because law enforcement targeted his vulnerability as a young adult during the undercover operation. We need not decide whether the statements at issue were admissible because, assuming the trial court erred by admitting the statements, the People have established beyond a reasonable doubt that the admitted statements did not influence the verdict. Because the admission of the statements was harmless error, at most, we affirm the judgment. II BACKGROUND On June 13, 2024, the San Diego County District Attorney filed an amended information charging Cook with the murder of Dorian Franklin

(Pen. Code, § 187, subd. (a); count 1),1 five counts of attempted murder (§§ 664, 187, subd. (a); counts 2–6), shooting at an occupied building (§ 246; count 7), and two counts of carrying a loaded firearm that was not registered

1 Further undesignated statutory references are to the Penal Code. 2 to Cook (§ 25850, subd. (a); counts 9–10).2 Counts 1 through 7 arose out of a gang-motivated drive-by shooting, while counts 9 and 10 arose out of an unrelated incident. As to count 1, the amended information alleged a special circumstance for shooting from a vehicle (§ 190.2, subd. (a)(21)), gun-use enhancements (§ 12022.53, subds. (d) and (e)(1)), a gang enhancement (§ 186.22, subd. (b)(5)), and an on-bail enhancement (§ 12022.1, subd. (b)). As to counts 2 through 6, it alleged premeditation and deliberation (§ 189), gun-use enhancements (§ 12022.53, subds. (c), (d), (e)(1)), gang enhancements (§ 186.22, subd. (b)(5)), and on-bail enhancements (§ 12022.1, subd. (b)). As to count 7, it alleged a gun-use enhancement (§ 12022, subd. (a)(1)), a gang enhancement (§ 186.22, subd. (b)(4)), and an on-bail enhancement (§ 12022.1, subd. (b)). The amended information also alleged four aggravating factors. (Cal. Rules of Court, rule 4.421(a)(3), (a)(5), (a)(8), (b)(1).) At the request of the defense, the court bifurcated trial on the gang enhancement allegations, the on-bail enhancement allegations, the aggravating factors, and counts 9 and 10. After a trial, the jury found Cook guilty of counts 1 through 7. The jury also returned true findings on the special-circumstance and gun-use allegations for those counts. The trial court granted the prosecution’s motion to dismiss counts 9 and 10, the gang enhancements for counts 1 through 7, and the on-bail enhancements for counts 1 through 7. In a bifurcated bench trial, Cook admitted the aggravating factors.

2 The amended information also charged counts 1 through 7, as well as count 8 (possession of a firearm by a felon), against Cook’s codefendant, Elijah Smith. Smith entered into a plea agreement before trial and pleaded guilty to one count of first degree murder with gun-use and gang enhancements. 3 The court sentenced Cook to state prison for life without the possibility of parole (LWOP), plus 50 years to life, plus five terms of life with parole, plus 84 years, which it calculated as follows: (1) LWOP on count 1, plus 25 years to life for the related gun-use enhancement; (2) life with the possibility of parole on count 2, plus 25 years to life for the related gun-use enhancement; (3) four terms of life with the possibility of parole on counts 3 through 6, plus 20 years for each related gun enhancement; and (4) the low term of three years on count 7, plus one year for the related gun-use enhancement. A. Prosecution Case Mike’s Market is a liquor store in the Mountain View neighborhood of San Diego. As of 2021, it was well known as a place where members of the 5- 9 Brims criminal street gang congregated. Mike’s Market is a few blocks east of territory claimed by West Coast Crips, a rival criminal street gang. On September 20, 2021, at 3:37 p.m., a drive-by shooting occurred while 17 people were gathered in the Mike’s Market parking lot to watch a fistfight. Surveillance video from Mike’s Market showed a white Honda Civic with spoked wheels, a damaged bumper, and a damaged driver-side mirror as it drove by the market in a westbound direction. The front passenger window and rear passenger window were both rolled down. A person in the front passenger seat wore a red cloth over the lower half of his face, and extended a handgun wrapped in a blue cloth out of the front passenger window. At least 10 shots were fired from the car into the parking lot, though the exact number of shots fired is indecipherable from the surveillance video. One person in the parking lot, Franklin, was struck by a bullet in the upper left back and died later that day. A second person, V.W., suffered non-fatal gunshot wounds to his right forearm and right thigh. Two additional bullets struck a nearby home.

4 Crime scene investigators later recovered six 9-millimeter shell casings and a bullet fragment from the parking lot. A bullet was also recovered from Franklin’s body. The markings on the shell casings were consistent with being fired from the same gun, which was never found. According to a ballistics analysis, the bullet recovered from Franklin’s body was most likely fired by a Smith & Wesson or an FN Herstal gun. The markings on the bullet were inconsistent with being fired from a Beretta gun. At 4:15 p.m., about 40 minutes after the shooting, a police sergeant familiar with the description of the Honda Civic saw the car parked in the parking lot of a 7-Eleven store located a 20-minute drive from Mike’s Market. Three young men stood by the car. They were later identified as Smith, a 24- year-old member of the Linda Vista Crips gang; Cook, an 18-year-old member of West Coast Crips, and J.M., a 15-year-old member of West Coast Crips. Surveillance video from the 7-Eleven showed the Honda Civic pulling into the parking lot at 4:12 p.m., 35 minutes after the shooting. The occupants exited the car, entered the store to buy merchandise, and returned to the car. Smith exited the car from the driver seat, Cook exited from the front passenger seat, and J.M. exited from the backseat. After the sergeant identified the suspect car, the young men got back into the car in the same seats they previously occupied and drove into a nearby alley.
