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

-1- #30443

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

-2- #30443

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

-3- #30443

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.
