Authorities say Ronning was working at Camp Cayuga in Wayne County when she disappeared on July 27, 1991, while out on a walk. Her partially clad body was found the next day. An autopsy determined she was sexually assaulted and shot in the head.
Officials say Plishka lived near the scene at the time. He is charged with first-, second- and third-degree murder and attempted involuntary deviate sexual intercourse.
Plishka is being held in Accomack County Jail awaiting extradition proceedings. It was immediately clear if he had an attorney Friday.
