MEMORANDUM OPINION BY

CHIEF JUDGE MARLA GRAFF DECKER

Keon Jamir Palmer appeals his convictions for first-degree murder and use of a firearm in the commission of murder in violation of Code §§ 18.2-32 and -53.1. He contends that the trial court erred by excluding a social-media video of the victim engaged in a fight with a third party and by ruling that the evidence was sufficient to prove he acted with premeditation. We hold that Palmer waived his challenge to the admissibility of the video. We also conclude that the evidence proved premeditation. As a result, the challenged convictions are affirmed.

BACKGROUND2

On February 21, 2024, Keon Jamir Palmer shot and killed Makayvia Cabell. At the trial that followed, the jury rejected his claim of self-defense and convicted him of first-degree murder and the related use of a firearm.

The evidence at trial established that Palmer and Cabell had a romantic relationship while the two were living in the Lynchburg home of Palmer’s mother during the first half of 2023. Also living in the home was Palmer’s younger brother Mekhi.

Palmer and Cabell’s relationship deteriorated into “chaos” and “arguments.” In July 2023, Palmer moved to Charlottesville to live with his father. Cabell also moved out of Palmer’s mother’s home.

In February 2024, Palmer returned to his mother’s home. On February 20, the day before the murder, he invited Cabell to visit, and she stayed overnight. The next morning, the two argued. While Palmer was in his mother’s bedroom and Cabell remained in the living room, the two engaged in a lengthy exchange of Instagram messages during which Palmer both said he would commit suicide and also threatened to kill Cabell. Shortly before 10:00 a.m., he messaged her and asked her to have sex with him “one last time.” He also said she could “have th[e S]mit[h & Wesson pistol] back when [he was] gone.” Cabell messaged him to “[c]hill out.” During additional exchanges, Palmer told her multiple times to leave the house.

2 The appellate court “review[s] the evidence in the ‘light most favorable’ to the Commonwealth, the prevailing party in the trial court.” Commonwealth v. Barney, 302 Va. 84, 96 (2023) (quoting Commonwealth v. Hudson, 265 Va. 505, 514 (2003)). Considering the evidence in this light requires the reviewing court “to ‘discard the evidence of the accused in conflict with that of the Commonwealth, and regard as true all the credible evidence favorable to the Commonwealth and all fair inferences to be drawn []from [that evidence].’” Tomlin v. Commonwealth, 302 Va. 356, 361 (2023) (quoting Commonwealth v. Perkins, 295 Va. 323, 324 (2018) (per curiam)).

Palmer eventually messaged Cabell that she should leave before he used a knife to kill her. She replied that he “ke[pt] getting [her t]here and kicking [her] out.” Palmer called her a “[b]itch” and said he had been “looking out for [her]” because she had “no[]where [to] sleep.” Cabell messaged him to leave her alone, saying her social worker would find lodging for her soon. Palmer replied that he would keep “popping” pills until she left.

About 10:15 a.m., Palmer entered the living room, and Cabell videoed their exchange with her phone. Palmer gave her some cash, produced a Smith & Wesson pistol, and tossed it toward Cabell where she sat on the couch. He told her to take the pistol “because [he] d[id]n’t need it [any]more” and to “get out.” He then went back into the bedroom. Cabell could be heard in the video commenting that Palmer had “picked [the pistol] up like he was about to shoot [her].”

In additional Instagram messages, Palmer “begg[ed]” Cabell to leave, saying, “You got your li[tt]l[e] gun,” and offering her more money “to get . . . out.” He then changed the focus of his messaging, saying, “[I]ma shoot you cause you got a gun and you[’re] in my house.” Palmer continued that he did not want her there because she was a “threat.” He added that he did not “trust [her],” was “scared,” and “fear[ed] for [his] life.” He followed up with, “Get out,” and, “I’m not try[ing to] put my hands on you.” Cabell messaged back, “You need help.” In response, Palmer said he would “be fine.”

Shortly thereafter, Palmer returned to the living room, and he and Cabell resumed arguing. Palmer again told her to leave. He threw Cabell’s purse and other personal items out of the house. According to Mekhi and Palmer, as Palmer grabbed Cabell’s belongings, she “pulled” the pistol, stood up, pulled the slide back, and pointed it “[d]irectly at” Palmer. The two men added that Cabell said she “ha[d] nowhere to go” and was not leaving. She then sat back

down, put the pistol down, and picked up her phone and a flashlight-style taser. She held these items in her hand while the gun remained beside her on the couch.

Palmer reacted by pulling down the retractable attic stairs, climbing up to the attic, and getting a larger gun, an AR-style rifle, before returning to the ground floor. He “paced back and forth” in the living room with the rifle and then carried it into the adjoining kitchen. Cabell was still sitting on the couch, facing away from the kitchen and toward the front door.

According to Mekhi, a little less than a minute after Palmer retrieved the rifle, Palmer’s “gun [went] off,” firing “[m]ultiple” shots. The shots, which came from the kitchen, hit Cabell, causing her to fall off the couch. As Palmer ran out the back door, Mekhi “screamed . . . why would he do that.”

Mekhi called 911. Cabell was transported by ambulance to the hospital, where she was pronounced dead.

After the shooting, Palmer fled and called a friend in a panic, looking for a car. He also asked people on social media if they could give him a ride.

Law enforcement officers investigating the shooting found five cartridge cases from an AR-style rifle on the kitchen floor, indicating the rifle was fired from “the front area of the kitchen,” fairly close to where Cabell was sitting. Palmer’s fingerprints were found on the Smith & Wesson pistol, but Cabell’s prints were not identified on that weapon. Social media photos from before the shooting showed Palmer holding what was believed to be the rifle with which he shot Cabell.

Cabell’s autopsy reflected that she sustained seven gunshot wounds and that several wounds to her torso caused her death. Additional evidence showed the trajectory of the bullet holes into her body and the couch. A video and various photographs of the crime scene were admitted into evidence, showing the proximity of the kitchen to the couch. This evidence,

combined with Mekhi’s testimony that Cabell was facing the front door when shot, proved that Palmer fired at least some of the shots at Cabell from behind, into her right shoulder and outside left thigh.

Palmer testified in his own behalf, contending that he shot Cabell in defense of himself and his brother, immediately after she said, “I’ve got something for you,” and “started reaching” for the pistol. He made conflicting statements about his own possession of the gun that morning, however, admitting he possessed it only when confronted with Cabell’s video of him giving the gun to her thirty minutes before the 911 call. According to Palmer, it belonged to her and he thought she was refusing to leave “because she wanted [it] back.”
