The Jefferson City man accused of gunning down his girlfriend and her estranged husband may have used an illegal sub-machine gun to kill the pair in 2009.
David Hosier is on trial on capital murder charges in Cole County this week. A Highway Patrol investigator says a World War II-era gun found in Hosier’s car was most likely used to kill Angela and Rodney Gilpin at a West Main apartment.
Hosier was caught hours after the killings in Oklahoma, with over a dozen loaded guns in his car. Hosier and Angela Gilpin had an affair but she was reconciling with her husband.
