IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA

FIRST APPELLATE DISTRICT

DIVISION TWO

THE PEOPLE, Plaintiff and Respondent, A169821 v. SHAUN PATRICK McMAHON, (Humboldt County Super. Ct. No. CR2101956) Defendant and Appellant.

A jury found defendant Shaun Patrick McMahon guilty of first degree murder and found he personally and intentionally discharged a firearm in committing the murder. On appeal, defendant contends the trial court erred, first, in admitting the preliminary hearing testimony of two witnesses after determining they were unavailable and, second, in refusing to instruct the jury on imperfect self-defense. Defendant also argues the court abused its discretion in declining to strike the firearm enhancement. We affirm. FACTUAL AND PROCEDURAL BACKGROUND Defendant and Benjamin Scott Thomas were friends, but in the weeks before the killing, defendant said he was not friends with Thomas anymore and was going to kill him. On the afternoon of June 23, 2021, defendant said if he saw Thomas, he was “gonna shoot” him. Thomas then appeared, and

1 defendant shot him. Thomas died from blood loss caused by a gunshot wound to his left thigh. The Humboldt County District Attorney charged defendant with murder (Pen. Code,1 § 187) and alleged defendant personally and intentionally discharged a firearm in the commission of the murder, causing great bodily injury and death (§ 12022.53, subd. (d)). A jury trial began in October 2023. The Prosecution’s Case The prosecution’s position was that defendant committed first degree murder under two theories: (1) lying in wait and (2) willful, deliberate, and premeditated murder. Evidence was presented of the following. Background Charles Garth owns a property in Trinidad, California, known as “Yee Haw” and a separate 320-acre property on Bald Hills Mountain Road (Bald Hills property) near Orick where marijuana is cultivated. In 2017 or early 2018, defendant, with his wife and her son, moved to the Yee Haw community. At some point, defendant told Garth he was not getting along with his wife and asked to stay at the Bald Hills property, and Garth allowed defendant to stay in a cabin on the property.2 Garth also permitted other people to stay at the Bald Hills property, generally in tents or trailers located within a few minutes’ walk from the cabin.3 About a week before the

2 Further references to the “cabin” are to this structure, that is, the

cabin on the Bald Hills property where defendant was staying in June 2021. 3 It is not disputed that Emmanuel Moya, Andrea Vasquez, Abel

Rodriguez, and Alejandra Sanchez were staying at the Bald Hills property in

2 shooting, Thomas told Garth “he wasn’t gonna go up there [to the Bald Hills property] anymore” because he was having a conflict with defendant. Heather Furchess met defendant and Thomas when she moved to Yee Haw. Defendant and Thomas both lived at Yee Haw at that time, and Furchess observed them daily for about a year. Defendant and Thomas were very good friends, but their relationship changed, and she had seen defendant being verbally aggressive with Thomas.4 Furchess testified that about two or three weeks before the shooting, she heard defendant say that “he could not trust [Thomas] anymore,” “[t]hat he was feeling betrayed,” “[t]hat [Thomas] was not his friend anymore and that he was going to get back at him,” and that “[h]e was going to kill him.” Emilia Bugarin-Faro also stayed on Garth’s property. About a week before the shooting, she was talking with Thomas and Andrea Vasquez when defendant approached and pushed Thomas on the shoulder. Bugarin-Faro testified Thomas “didn’t want confrontation [sic] with him” and “took off running.” Then defendant “came with a rooster who had—like his head was kind of bleeding,” and “threw the rooster right next to” Bugarin-Faro, and she was “somewhat frightened.”5

June 2021. Vasquez described the Bald Hills property as “like a hippie community” and “really peaceful.” 4 Asked whether the verbal aggression between defendant and Thomas

was “one-way or both ways between them,” Furchess responded it was “one- way” with defendant as the aggressor. 5 Vasquez testified she talked to defendant after he threw the rooster.

She did not remember the conversation well but recalled that defendant was “mad.” According to Vasquez, defendant and his wife had broken up, and Thomas gave defendant advice, “like, you know, ‘You should just move on,’ ” but defendant “didn’t like that,” “[l]ike [Thomas] was giving the wrong advice for him.”

3 The Shooting On June 23, 2021, Bugarin-Faro was at the Bald Hills property near the cabin. She saw Thomas and Kevin Brown arrive at the property in Brown’s vehicle and defendant sitting outside the cabin. Bugarin-Faro saw defendant “rise up from his seat and grab the firearm” and say something to Thomas. Defendant pointed the firearm at Thomas, and Thomas said something to defendant. Bugarino-Faro did not speak English and did not understand, but what Thomas said “wasn’t like a nice phrase.” Thomas “raised his hands” and “went towards” defendant. Thomas had nothing in his hands and had no bag or backpack. Bugarin-Faro turned around and ran to get help from her friends, Emmanuel Moya and Andrea Vasquez, who were nearby.6 Then she heard a gunshot. Kevin Brown worked with Thomas on the Bald Hills property. (Brown described his work as “[d]igging holes” for growing marijuana.) Brown had seen Thomas working with defendant on the property in the past. Thomas and defendant appeared to be friends (they were “always like drinking and smoking, talking”), but Brown also observed that defendant was “always upset and saying Thomas is dictating to him, and Thomas is being like a sheriff, and he shoot sheriff [sic].” Brown never saw Thomas do anything aggressive toward defendant. On the afternoon of June 23, 2021, Brown drove with Thomas from Trinidad to the Bald Hills property to do some work. The drive took about one-and-a-half to two hours. When they arrived, Thomas got out of Brown’s

minute to minute-and-a-half’s walk from where she observed defendant, Thomas, and Brown.

4 truck and opened a gate. Brown drove in and parked next to the cabin, which was not far from the gate,7 while Thomas followed on foot. Defendant was sitting outside the cabin. He said to Brown, “ ‘Oh, if I see that fuckin’ Thomas on the mountain, I have one bullet, and I’m gonna shoot that fucker.’ ” Defendant said he was going to shoot Thomas “ ‘because he talks bad about me and talks bad about everybody.’ ” Then Thomas appeared. Defendant seemed “aggravated”; he pointed at Thomas and said, “ ‘Motherfucker, I’m gonna shoot you because you talk bad about me, and you talk bad about everybody.’ ” Brown testified defendant “was trying to go back to the cabin like he was gonna go get something.” Brown “ ‘d[id]n’t want to be part of this’ ” and started to unload soil from his truck. He heard arguing, and Thomas said, “ ‘Go for it, bro, go for it.’ ” Brown “heard the explosion” of a gunshot. Defendant walked into the cabin “with the gun”; this was the first time Brown saw a firearm. After the gunshot, Thomas, who was standing about 10 feet from the cabin, checked himself (he “lift[ed] his shirt up” and “pulled his pants down a little”), and Brown saw blood. Thomas then ran inside the cabin. Brown heard a commotion and went in the cabin.
