COURT OF APPEAL, FOURTH APPELLATE DISTRICT

STATE OF CALIFORNIA

THE PEOPLE, D082910

Plaintiff and Respondent,

v. (Super. Ct. No. SCE394555)

CHRISTIAN GOMEZ LOPEZ,

Defendant and Appellant.

APPEAL from a judgment of the Superior Court of San Diego County, Patricia K. Cookson, Judge. Affirmed. Valerie G. Wass, under appointment by the Court of Appeal, for Defendant and Appellant. Rob Bonta, Attorney General, Lance E. Winters, Chief Assistant Attorney General, Charles C. Ragland, Assistant Attorney General, A. Natasha Cortina and Kelley Johnson, Deputy Attorneys General, for Plaintiff and Respondent. One afternoon in May 2016, a group of teenagers were hanging out in front of an apartment complex in Spring Valley. Christian Gomez Lopez, a known gang member, and another man drove up to the group. Lopez got out of the car and confronted the teens about their gang membership. Moments later, Lopez attacked one of the teenagers, 17-year-old Jeffrey Quirino, with a knife, slicing his neck and killing him. Lopez and the other man fled the scene, and the crime went unsolved for several years. In 2019, Lopez was in custody for an unrelated crime. The detective investigating the unsolved killing organized a Perkins operation using a confidential informant and undercover police officer to attempt to obtain

information about Lopez’s role in the homicide.1 The operation was successful and, during conversations with the confidential informant, Lopez confessed to killing Quirino. Lopez was charged with and convicted of second degree murder. Lopez also pleaded guilty to charges of assault with a deadly weapon and making and possessing weapons in a penal institution. The trial court sentenced Lopez to an indeterminate prison term of 15 years to life plus one year, plus a determinate prison term of 15 years and 8 months. On appeal from the judgment of conviction, Lopez makes several arguments. He asserts the trial court erred by denying his request to suppress statements he made during the Perkins operation. Lopez also argues the court abused its discretion by denying his motion for the disclosure of the personnel records of two San Diego County Sheriff’s deputies involved in his case. Lopez additionally asks this court to conduct an independent review of two in camera proceedings held by the trial court to determine whether to allow the disclosure of the identity of the confidential informant and undercover police officer involved in the Perkins operation,

1 Illinois v. Perkins (1990) 496 U.S. 292 (Perkins). 2 and a third confidential informant who identified the man driving Lopez at the time of the murder. Finally, Lopez argues the trial court abused its discretion by imposing the mid-term sentence on the assault with a deadly weapon conviction and by failing to strike a prior strike conviction and a serious prior felony enhancement. As we shall explain, we reject Lopez’s appellate contentions. We have also conducted an independent review of the in camera proceedings and conclude the court properly rejected Lopez’s request for disclosure of the identities of the confidential informants and undercover agent. Accordingly, the judgment of conviction is affirmed. BACKGROUND A. Factual Background On the afternoon of May 23, 2016, 17-year old Quirino was hanging out after school with four friends ranging in age from 15 to 17 years old. The five teenagers were in front of an apartment complex on the corner of Delrose Avenue and Elkelton Boulevard in Spring Valley. Quirino and his friends hung out there regularly after school. Quirino’s friends testified at trial that

neither they nor Quirino were gang members.2 Quirino was sitting in his Camaro, which was parked in front of the complex, and his friends were standing around the car. A gray SUV drove up and stopped near the group of teenagers. A man, later identified as Lopez, got out of the passenger side of the SUV, walked toward the group, and asked them where they were from. Some of Quirino’s friends responded that they

2 The trial court read three stipulations to the jury concerning the group’s criminal history: Quirino had a true finding in a juvenile matter in 2015 for felony resisting arrest, a companion had a true finding in 2015 for throwing a substance at a vehicle, and another companion had a true finding in 2010 for felony battery. 3 did not “bang.” Quirino stood up, walked toward Lopez, and said something like “we don’t bang but my brother’s from Lomita.” Lopez responded, “Fuck Lomita” and stabbed Quirino in the neck with a knife. The cut severed Quirino’s carotid artery, and blood began spurting from his neck. About the same time, the driver of the gray SUV got out and came around the vehicle, towards Lopez. The two men then ran back to the SUV and drove away. Neighbors called 911. Meanwhile, Christopher E. was driving his sedan on Elkelton Boulevard. His girlfriend, Jasmin Z., and her sister, Crystal R., were in the car. They saw a commotion as they neared the apartment complex. When Christopher stopped at the stop sign at the corner of Delrose and Elkelton, Crystal saw two people enter a parked gray SUV and drive off. Moments later, she observed a group of people on Delrose standing around a man who was leaning against a car and bleeding from his neck. Crystal asked the group if they needed help. Someone helped Quirino into the back seat of the sedan, and he collapsed onto Crystal, who was sitting in the back passenger seat. Blood was gushing out of a large wound on the left side of Quirino’s neck. Crystal took off her shirt, wadded it up, and applied it to the wound. Christopher sped toward the hospital. Quirino lost consciousness on the way, and his breathing became shallower. When they arrived at the hospital, Quirino was taken in on a gurney and Crystal, Jasmin and Christopher waited outside to speak with police. By this time, several San Diego County Sheriff’s deputies arrived at the apartment complex and began speaking with Quirino’s friends and other witnesses. Based on evidence the witnesses provided, the deputies alerted law enforcement to be on lookout for the suspects.

4 Quirino died from the stab wound to his neck, which was two- to two- and-a-half inches deep. The knife severed his carotid artery and cut his jugular vein. Two days after the stabbing, Crystal provided law enforcement with a description of the gray SUV and its occupants. She also helped create a composite sketch of the driver, which law enforcement included in a bulletin issued to the public. In July 2016, officers located a Hyundai Santa Fe that matched images of the SUV captured on surveillance cameras near the stabbing. The Sante Fe was registered to Juan Carlos Arguelles. Officers impounded the vehicle and processed it for fingerprints. Arguelles resembled the composite sketch of the driver Crystal helped prepare and his social media posts suggested he was a member of the Logan Heights Gang. Sheriff’s deputies interviewed Arguelles but released him later that day. In 2017, investigators determined three fingerprints lifted from the Santa Fe’s front passenger window matched Lopez’s fingerprints. Then the investigation stalled. In 2019, a new detective, Jacob Wilson, took over the investigation after the former detective retired. Based on his review of the evidence that had been collected, Wilson believed Arguelles was the driver of the SUV during the stabbing.
