On Sunday, March 29, 2020, Mochdaveyano “Blackhawk” Fisher was found dead inside a home in Big Horn, a small community near Sheridan, Wyoming. He was a 25-year-old Native American man. Deputies were sent to the residence after authorities received word that the homeowner, Dana Beartusk, had contacted a family member and said he had killed someone.
When an officer arrived at the single-wide trailer on Willow Street, the scene inside quickly unfolded into something far worse: three relatives were dead—Fisher, Seana Fisher, and Angelina Beartusk.
Investigators later described how the victims were discovered in different parts of the trailer—one slumped at a table and two others on the floor and on a bed—each with an apparent gunshot wound to the head. Court documents referenced in reporting said a neighbor recalled hearing gunshots around 7:45 p.m. that evening, and prosecutors told the court the wounds were consistent with execution-style shootings. While the first responding officer worked to secure the residence, deputies began searching for Beartusk, who had already left the area.
As the night stretched on, the account that emerged was of a suspect moving away from the violence almost in real time. Reporting described Beartusk calling his brother to confess and then fleeing in a vehicle, with information relayed to law enforcement suggesting he traveled through Sheridan before heading north toward Montana. He was arrested that same night in Montana, and investigators later noted items and observations from the arrest, including a red T-shirt and signs of blood spatter, as well as a single. 40-caliber bullet found in his vehicle.
The case moved swiftly into the courts. Beartusk was initially charged with three counts of first-degree murder, held in the Sheridan County detention center on a $750,000 cash-only bond, and a trial date was later set before the case took a decisive turn. In May 2020, three firearms believed to belong to him were reported found along a roadway near Kirby, Montana, and authorities described one as the murder weapon, a. 40-caliber Glock pistol.
In February 2021, Beartusk pleaded guilty to three amended counts of second-degree murder as part of a plea agreement, telling the judge he had been intoxicated at the time of the killings. In April 2021, a judge sentenced him to three consecutive prison terms of 45 years to life—effectively a life sentence stacked three times over—closing the criminal case with a conviction and punishment, even as it left behind the irrevocable absence of Fisher and the two women killed alongside him.
