COLUMBUS, Ohio — A man who was shot dead last month as authorities attempted to serve him an indictment on federal gun charges has been identified as the killer of an 18-year-old Ohio woman in a case that had gone unsolved for 43 years, police announced Monday.

A police shootout led authorities in Ohio to solve a cold case murder from 1981. Swat police and U.S. Marshals swarmed a motel room near North Canton last month. The man inside died after investigators said he barricaded himself inside and started a gunfight while a warrant was being served on federal gun charges.
