Senior Airman Tristen Carlson, 21, was shot and killed in the early hours of February 2, 2020, at an off-base apartment in Great Falls, Montana. Police responded to a 911 call about 2:27 a.m. from a woman at an apartment complex on 14th Avenue South; Carlson was found with a gunshot wound to the head and was pronounced dead at the scene. The caller and the apartment’s resident, Christopher Contardo, were both present and the caller had attempted CPR.

Investigators identified 26-year-old former airman Christopher Domonic Contardo as the person who fired the weapon. Defense statements said both men had been drinking and were handling a 9mm handgun when it discharged while Contardo had the firearm. Contardo was arrested and charged with negligent homicide. In April 2021 he pleaded guilty; the mediation-based plea recommended 150 days in a prerelease center followed by six years of probation, and required Contardo to buy a $100 savings bond for Carlson’s daughter on each anniversary of his death during probation.

Does anyone have information about Carlson’s time at Malmstrom or the party that night that could help clarify what happened?
