Summary based on 10 sources
Feli Ann Sjostrom was a 36-year-old White female from Gillette, Wyoming. Late on the morning of Friday, January 10, 2020, a relative discovered her and a man inside a Gillette residence, and police began working the scene to understand what had happened.

As investigators pieced together the moments that led to the deaths, Gillette Police said the evidence pointed to a domestic murder-suicide: police identified Richard Massman as the person who shot Sjostrom with a handgun and then turned the gun on himself. Authorities described the case as an apparent murder-suicide and publicly outlined their findings a few days later, after the initial response and early investigation.

Because Massman also died at the scene on January 10, there was no arrest, no suspect search, and no later criminal case moving through court. The investigation's conclusion effectively closed the question of who was responsible, leaving no trial, plea, or conviction to follow—only the finality of two deaths and the grief that followed in their wake.

In the days after the shooting, tributes and memorial posts described Sjostrom's life in the years leading up to her death—where she had lived, the family members she loved, and the community spaces where people planned to gather and remember her. A service was announced for the following week in Gillette, offering friends and family a chance to speak her name aloud in a room full of those who knew the shape of her life before it ended.
