THE PEOPLE, F088521 Plaintiff and Respondent, (Super. Ct. No. VCF409217) v.

MARVIN JOSEPH CHANG, OPINION Defendant and Appellant.

APPEAL from a judgment of the Superior Court of Tulare County. Nathan G. Leedy, Judge. Sylvia W. Beckham, under appointment by the Court of Appeal, for Defendant and Appellant. Rob Bonta, Attorney General, Lance E. Winters, Chief Assistant Attorney General, Kimberley A. Donohue, Assistant Attorney General, Amanda D. Cary, Lewis A. Martinez, and William K. Kim, Deputy Attorneys General, for Plaintiff and Respondent. -ooOoo- INTRODUCTION Defendant Marvin Joseph Chang was convicted in July 2024 of a litany of charges stemming from a police chase and gun battle with officers outside of Three Rivers. Defendant suffered from delusions that he was being pursued by CIA agents who intended to harm or kill him. The sole issue on appeal here is whether the trial court should have provided an instruction on imperfect self-defense during the guilt phase of the trial to permit defendant to argue that his belief in the necessity of self-defense was honest, if not reasonable. The court denied this instruction, citing People v. Elmore (2014) 59 Cal.4th 121 (Elmore). Elmore stands for the proposition that imperfect self- defense may not be invoked by one who is operating entirely under the influence of a delusion, without an “objective correlate.” (Id. at pp. 136–137.) We find the mere presence of a peace officer cannot be such an objective correlate. The objective correlate must at least conceivably relate to a reasonable need for self-defense. Imperfect self- defense is a species of mistake of fact, where a person may hold the actual, if unreasonable, belief that self-defense is necessary. A pure delusion is not a mistake of fact; rather, it is “perception of facts not grounded in reality.” (People v. Mejia-Lenares (2006) 135 Cal.App.4th 1437, 1453, fn. omitted (Mejia-Lenares).) Defendant’s belief that all peace officers were working on behalf of the CIA to kill him is clearly a delusion, not just a mistake of fact. FACTUAL AND PROCEDURAL BACKGROUND On February 19, 2021, E.M. was at a gas station in Three Rivers, searching for her purse while seated in her car. She heard a knock on the window and saw a gun pointed at her. A man asked for her purse, but having not turned off the car, she drove away instead of giving it to him. E.M. stopped her car approximately a block away and called 911. While waiting for assistance to arrive, she heard gunshots. Additionally, Megan T., who worked nearby, also heard gunshots around this time.

2. A 911 dispatch went out reporting that shots were fired at the gas station in Three Rivers and directing officers to be on the lookout for a white Prius, driven by a man dressed in gray. Officers Crass and Wallace heard the call and decided to respond, knowing that the only road out of Three Rivers would take someone past their current position. The officers, who worked for CalFire, were wearing peace officer uniforms, but were in a CalFire truck. They spotted defendant, wearing a gray sweatshirt, driving a white Prius westbound away from Three Rivers. The officers turned to follow defendant and engaged their lights and sirens to pull him over. Defendant displayed a firearm out of the window of the car while the officers were behind him. A short while later, defendant stopped suddenly on the highway, partially turning his car in the middle of the highway. He then opened the car door and immediately began firing at Officers Crass and Wallace. The officers had no opportunity to give defendant commands of any kind, because he started firing before they even left their vehicle. The officers returned fire. Defendant then sped away, and the officers resumed their pursuit of him. Other deputies joined in the pursuit, as defendant continued to fire shots out of the car’s window. The Prius and pursuing vehicles exceeded speeds of 95 miles per hour during the chase. Defendant ran several other vehicles, including a UPS truck, off the road while fleeing down the highway. Additional officers, including Officer Wilson of the California Highway Patrol, joined in the pursuit. Meanwhile, ahead of the convoy, another deputy was deploying spike strips across some of the lanes of traffic. As defendant reached that deputy, he veered to the other side of the freeway and turned onto another road while firing at the deputy from his car. As the various officers continued their pursuit on this other road, smoke began billowing out from the Prius, at which point defendant drove the car into an orchard and stopped. After the car came to a stop, defendant fled on foot. Most of the officers set up a perimeter around the orchard to prevent him from leaving.

3. Officer Wilson proceeded into the orchard to check the Prius and attempted to locate defendant, ultimately parking her vehicle behind defendant’s. After she climbed out of her vehicle, defendant began firing at Wilson from the trees, and she retreated behind her vehicle and returned fire. When Wilson went to reload her gun, the magazine did not seat correctly and fell out of the gun and onto the ground, at which point defendant ran towards her, continuing to shoot. Wilson attempted to move around the vehicle, but was shot in the shoulder, breaking her collarbone. After being shot, and while running away from defendant, Wilson slipped and fell to the ground, which allowed defendant to catch up with her. Wilson testified that, at that moment, she was “anticipating getting shot in the back of the head.” Defendant did not shoot Wilson again, but began striking her with a hard object, presumably the handgun he was holding. Another officer spotted defendant and Wilson fighting and fired several shots, which caused defendant to flee. Several remaining officers pursued defendant as he fled the scene where he had assaulted Officer Wilson. He was spotted by Officer Wallace, who shouted to alert the other officers as to defendant’s location. When defendant heard the shouting, he turned toward Wallace and, believing he might be fired upon next, Wallace shot defendant in the leg with a shotgun slug. Following this, defendant was handcuffed and arrested. Officers found a nine-millimeter firearm with an extended, 30-round magazine and a live round jammed in the chamber, lying next to defendant. Defendant was also wearing body armor under his sweatshirt. Additionally, when officers searched defendant’s car, they located an assault rifle with an extended, 50-round magazine, a machete, a pan with mushrooms in it, copious amounts of ammunition for both the rifle and the pistol, several extra magazines, and marijuana. The assault rifle was behind the driver’s seat, wrapped in a blanket. The mushrooms were hallucinogenic. Although defendant’s toxicology screen did not detect any psilocybin or THC—the active ingredients in hallucinogenic mushrooms and marijuana, respectively—the evidence

4. indicated the metabolites of psilocybin are very unstable and are removed from the body very quickly and, therefore, the test could not rule out the use of mushrooms. Defendant testified in his own defense. He stated he normally lived in Los Angeles with his mother. Although he had moved out some months prior, he returned to the house a few days before the incident to leave his mother a note1 and “grab some … camping gear and things to survive in the wilderness.” Defendant had decided to “live inside the national park,” because he was scared “[o]f the government and CIA trying to silence [him].” He said he first noticed “a white pickup truck following [him] on the 10 freeway by the Rosemead exit,” which he believed was the CIA. He also claimed a helicopter was following him through several different cities in Southern California.
