On Valentine’s Day in the winter of 1989, 28-year-old Detective Alexander Finlayson Mavity of the Billings Police Department was killed while on duty. A department veteran of eight years, Mavity was escorting a man identified as Ronnie Duworth—arrested on a parole violation after a domestic disturbance—into the rear of the station when Duworth fled and a pursuit led into a nearby alley.

A physical struggle occurred in the alley during which Duworth gained control of Mavity’s service weapon. Shots were fired; Detective Mavity was fatally wounded and Duworth was also shot and killed in the confrontation. Mavity is remembered as a son, brother, husband and father to a young daughter. The Mavity Law Enforcement Memorial was dedicated in May 1992 in front of the Billings Police Department.

Did anyone in Billings at the time witness the alley confrontation or have memories of Detective Mavity that could add to his story?
