Seana Fisher, 54, was one of three family members found dead inside a home on Willow Street in Big Horn, Wyoming, after deputies responded to an urgent call on the evening of March 29, 2020. Investigators say a man contacted a relative and claimed he had killed someone; when officers arrived they discovered an adult male and two adult females dead at the scene. Authorities identified relative Dana Beartusk of Big Horn as the suspect; he fled north and was arrested in Montana later that night.

Three firearms tied to Beartusk, including a .40-caliber Glock described as the murder weapon, were recovered near a roadway by Kirby, Montana. Beartusk later changed his plea in February 2021, admitting guilt to three amended counts of second-degree murder and telling the judge he had been intoxicated and did not remember disposing of the guns. In April 2021 Judge John Fenn imposed three consecutive terms of 45 years to life.

Did anyone in the Sheridan or Big Horn area know Seana Fisher or the other victims and have information to share?
