WEST NANTICOKE, Pa. (AP) — A prosecutor says a Pennsylvania Fish and Boat Commission waterways conservation officer was justified in shooting and killing a man after authorities said the man assaulted him.

Luzerne County District Attorney Stefanie Salavantis said the officer fended off multiple attacks along and in the Susquehanna River before shooting 37-year-old Sean Bohinski three times at close range.

Officials said the officer found the man burning insulation off copper wire that the officer believed was stolen. While being frisked, he struck the officer in the face and then attacked him repeatedly with a rock from the river.

Salavantis said the officer tried to defend himself using spray and a baton but was unable to reach the baton and was bleeding excessively, dizzy, and exhausted, so he drew his weapon and fired.
