OPINION FILED 10/15/25

DEVANEY, Justice and JENSEN, Chief Justice [¶1.] Justice DeVaney delivers the opinion of the Court on Issue One. Chief Justice Jensen delivers the opinion of the Court on Issue Two. [¶2.] DEVANEY, Justice, writing for the Court on Issue One. [¶3.] Dion Bordeaux was convicted by a Pennington County jury of first- degree murder in violation of SDCL 22-16-4(1) for shooting his girlfriend. He was sentenced to life imprisonment without the possibility of parole. At trial, the circuit court allowed other act evidence stemming from a prior aggravated assault Bordeaux committed against a different victim to be presented to the jury. Bordeaux appeals, contending the circuit court abused its discretion in admitting this evidence. He further claims he was prejudiced by the admission and seeks a reversal and remand for a new trial.

Factual and Procedural Background [¶4.] In the early morning hours of January 1, 2020, Jeanette Jumping Eagle died from a single gunshot wound to her forehead. Jeanette had spent the preceding New Year’s Eve with her boyfriend, Bordeaux, his brother, Giovanni Bordeaux, and some of her family members and friends in a hotel room she had rented at the Microtel Inn in Rapid City, South Dakota. While others came and left the hotel room throughout the evening, only Bordeaux and Giovanni were in the room at the time of Jeanette’s death. [¶5.] According to Giovanni’s trial testimony, Bordeaux and Jeanette had been arguing throughout the night, and it appeared to Giovanni that the couple was on the verge of a break-up. He testified that the two were acting “childish” and

calling each other names, which made him feel uncomfortable. Giovanni had made arrangements with his coworkers to pick him up at the hotel after their shifts ended. While waiting in the hotel room for them to arrive, Giovanni went into the bathroom. As he was urinating, he heard a loud bang. He then finished, zipped up his pants, and opened the bathroom door. When he did so, he smelled gunpowder and observed Bordeaux standing “next to the wall.” Giovanni described Bordeaux as “freaking out” and when he asked him what had happened, Bordeaux responded, “I don’t know, I don’t know, I don’t know.” [¶6.] Giovanni testified he caught a glimpse of Jeanette on the couch bleeding from her head, but his view was obstructed by Bordeaux, who was standing a foot or two in front of her. He could not see what, if anything, Bordeaux was doing with his hands at that time, but he did recall Bordeaux thereafter going into the bathroom. He did not remember seeing a firearm on or near Jeanette. He explained that the two of them were panicking, and after Bordeaux came out of the bathroom, he told Giovanni “to run, to leave the room.” They then left the hotel room together and Giovanni recalled Bordeaux stating that he was going to call the police. Giovanni said that they left the hotel and began walking and running down Lacrosse Street toward several retail businesses. Giovanni testified that Bordeaux kept repeating “I’m sorry” and also stated, “I fucked up.” [¶7.] They eventually split up, and Bordeaux stopped near the Runnings store and called 911. While breathing hard and crying, Bordeaux told the 911 dispatcher that his girlfriend “just shot herself.” After the dispatcher asked him to repeat himself, he stated: “I broke up with her and said I’m leaving and she shot

herself. She had a gun.” The dispatcher asked how he knew she shot herself if he was leaving, and Bordeaux responded, “I heard it, I was going out the door and heard a loud noise.” Bordeaux gave the hotel room number to the dispatcher and also explained his location on North Lacrosse Street. [¶8.] When law enforcement officers arrived at the hotel, they found Jeanette, deceased, sitting in a slumped position on the couch with a gunshot wound above her right eyebrow. There was a large pool of blood, mostly to her right side, on the right arm of the couch and the cushion underneath her. There was a 9- millimeter Ruger handgun on her lap and her right hand was lying over the bottom of the grip. Jeanette’s cell phone was underneath her right wrist, resting partially on the upper side of her right leg. A charging cord was attached to the phone and plugged into a charger, and part of the cord was wrapped around the little finger of Jeanette’s right hand. [¶9.] Meanwhile, other police officers found Bordeaux standing on Lacrosse Street near Runnings. Officer Matthew Husfeldt approached him, with his body camera activated, and asked him to explain what happened. Bordeaux told the officer that he and Jeanette got into a fight and he broke up with her. He explained that when he was walking out the door, he heard a loud bang that sounded like a gunshot, after which he and his brother took off running. Officer Husfeldt asked him if his girlfriend had a history of suicidal tendencies and Bordeaux told him that they had only been dating a few months. He stated that she said she would do this if he left her, but he did not think she would. He further explained that they were fighting because he told her to stop drinking. He told the officer that she gets

violent when drunk and claimed she was pushing him around that evening. According to Bordeaux, when he told Jeanette he was going to leave, she said, “Fuck you, leave me then.” Then, while he was by the bathroom door telling Giovanni they should go, he said he heard the loud noise and thought she had shot at him, so he told his brother, “Let’s go, let’s go.” Bordeaux explained that after they realized she was not chasing them, he told Giovanni to go home. He also told the officer that Jeanette always had a gun in her purse or her car. [¶10.] At numerous times during this discussion with Officer Husfeldt, Bordeaux would lie face down in the grass next to the sidewalk or would grab handfuls of grass, and he intermittently appeared to be crying. He asked the officer several times if Jeanette was okay. When Officer Husfeldt told him she was deceased, after a long pause he stated, “I didn’t think she’d do that.” He then asked for water, but before the officer brought him a bottle of water, Bordeaux walked over to a pile of snow and put a handful of snow in his mouth. [¶11.] Bordeaux agreed to travel with law enforcement to the police station for a formal interview. When requested, he gave Officer Husfeldt his phone. Prior to going to the police station, another officer asked him to submit to a preliminary breath test. Once at the station, police learned of an active arrest warrant for Bordeaux pertaining to an aggravated assault that occurred in September 2019 in Lincoln County and he was arrested on that charge.1 Bordeaux then requested a

1. This assault is the other act at issue in this appeal. According to testimony elicited at trial, Bordeaux pled guilty to this assault and was convicted.
