Michael Standing Elk was a 42-year-old Native American man from the Wind River Reservation near Riverton, Wyoming, known to family and friends as a big-hearted presence who loved driving around, listening to music, teasing his siblings, and spending time with his large extended family. He was born in Riverton and grew up on the reservation, later earning a heavy equipment certification through Job Corps and working for local tribal programs, including road work, utilities, and security at the
Wind River Hotel and Casino. His home life was rooted in the Northern Arapaho community, and he was closely connected to his mother, stepmother, daughter, siblings, grandparents, and many nieces, nephews, and cousins who regarded him as both relative and friend.
By 2023, Standing Elk was the landlord of a residence on Rendezvous Road in the St. Stephens/Arapahoe area of the Wind River Indian Reservation, just outside Riverton. Earlier that year, he had evicted a tenant, 58-year-old Burdick Nelson Seminole Sr., after allegations that Seminole was using drugs at the house and bringing young females there to get them high. Once Seminole was gone, Standing Elk began renting the home to other tenants, and the house became crowded, with multiple adults and several children living inside and others staying in vehicles parked on the property. What should have been a fresh start for the landlord and his new tenants instead became a slow build of resentment; Seminole believed Standing Elk was “talking smack” about him and, according to his later statements to investigators, felt that his former landlord was threatening his daughter.
The conflict erupted on the morning of August 8, 2023. Around 8 a.m., Seminole returned to the Rendezvous Road residence and went straight into the bedroom where Standing Elk was asleep beside his partner. He turned on the light and began slapping Standing Elk in the head, taunting him with words to the effect of “talk s— now,” waking not only the victim but also others in the crowded home. As the argument escalated, Standing Elk tossed his phone to his partner and told her to call 911 while he maneuvered himself into his wheelchair and rolled down the hall after Seminole. In the living room, in front of multiple witnesses, Seminole began pistol-whipping him, striking his face with a handgun. Witnesses later told investigators that both men had access to guns and that at one point Standing Elk tried to fire a weapon, but it jammed. One recalled him giving up, saying something like, “OK, I'm done, you win, Burdick,” just seconds before Seminole opened fire. A shot to the chest left him slumped over in his wheelchair, mortally wounded, while another tenant stepped from a bedroom doorway, fired at Seminole, and then retreated as gunfire rang through the house.
Seminole fled the residence, wounded by the return fire, and drove himself to Wind River Family and Community Health Care, known locally as Wind River Cares, seeking treatment. There, he spoke with investigators, admitting he had gone back to confront his former landlord because he was tired of him “talking smack” and claimed that he believed his daughter was being threatened. He described a confused, “blacked out” memory of the shooting, saying he remembered retrieving a. 45-caliber pistol and then “shooting back” but not fully recalling each shot. Agents found a black Springfield XDS pistol in the front passenger seat of his vehicle, loaded with a round in the chamber, and one officer overheard him say, “I shouldn't have picked up that gun.” Back at the house on Rendezvous Road, authorities found Standing Elk unresponsive, with gunshot wounds to his chest; a Bureau of Indian Affairs agent and medical personnel confirmed there was no pulse. The Fremont County coroner's office later ruled that he had died from multiple gunshot wounds and classified the death as homicide, noting various forms of Delta-9 THC in his system. In the weeks that followed, federal agencies including the FBI and BIA were criticized locally for their silence, even as word spread that an Arapahoe resident had been killed in a shooting on the Wind River Reservation.
The investigation quickly focused on Seminole as the sole suspect. Because the shooting occurred on reservation land and both men were tribal community members, federal authorities took jurisdiction. Prosecutors charged Seminole in U.S. District Court with first-degree murder, using, carrying, brandishing and discharging a firearm during a crime of violence, and causing death with a firearm during a crime of violence. Each firearm count carried the potential for lengthy additional prison time on top of the life sentence possible for first-degree murder. Court filings described a volatile mix of resentment over the April eviction, alleged drug use, and the crowded, fragile living arrangement that had developed in the months before the shooting, painting a picture of a landlord-tenant relationship that had curdled into hostility long before that August morning.
Through 2024, the case moved steadily toward trial. Seminole initially signaled that he would rely on an insanity defense, prompting orders for mental health and competency evaluations. A federal judge later found him competent to proceed, and by the time the jury was empaneled he had abandoned the insanity plea and maintained a not-guilty stance. During a four-day trial in Casper in November 2024, jurors heard from multiple eyewitnesses inside the home, investigators who collected physical evidence and recorded Seminole's statements, and experts who testified about the cause of death. The prosecution framed the killing as an act of deliberate violence by a resentful former tenant who returned to confront and ultimately shoot his disabled landlord; the defense emphasized Seminole's claim that he believed he was under threat and that his memory of the shooting was foggy. When deliberations ended, the jury found Seminole guilty of first-degree murder, discharging a firearm during a crime of violence, and causing death with a firearm during a crime of violence. His sentencing hearing was first set for February 6, 2025, then rescheduled to February 27, 2025, after his attorney requested more time to gather letters and materials in mitigation. As he awaits sentencing and the formal pronouncement of a likely life term, the case stands as a resolved homicide in which the man who killed Michael Standing Elk has been convicted in federal court, even as family and community continue to live with the loss of the landlord, relative, and friend who never left his wheelchair that August morning.
