Feli Ann Sjostrom was 36 and from Gillette, Wyoming. Late on the morning of Friday, January 10, 2020, a relative found her and a man inside a Gillette home; police later concluded the scene was a domestic murder-suicide. Investigators said Richard Massman shot Sjostrom with a handgun and then turned the gun on himself, and both were found dead at the scene that day. Because Massman also died, there was no arrest and no criminal case to follow.

In the days after the deaths, tributes and memorial posts recalled where Sjostrom had lived, the family members she loved, and community gatherings planned to remember her. A service in Gillette was announced for the week after the shooting. If anyone knew Feli Ann Sjostrom or has information about her life in Gillette, please share what you remember.
