Muriel Chidsey was 85 when she died at home in Lander, Wyoming, on September 7, 2016. The Fremont County Coroner’s Office ruled her death a homicide after she and her husband, Charles Chidsey, were found inside their residence on September 8. Authorities determined Charles shot Muriel and then died of a self-inflicted gunshot wound, and the coroner concluded the deaths occurred about a day earlier.

Investigators said the evidence suggested the act had been planned in advance, framing the deaths as a deliberate homicide-suicide rather than an accident or impulsive act. Because the suspected shooter died at the scene, there were no arrests or prosecutions.
