In the early hours of June 4, 2001, Gregory Guy Collins, a 31-year-old correctional officer from Vienna, Maryland, was found shot to death in his gray Toyota pickup after failing to return home from his shift at Eastern Correctional Institution. A state trooper located the truck in a wooded area off Indiantown Road where it appeared to have left the roadway; Collins was unresponsive with a single gunshot wound to the back of the head and the truck had four bullet holes.

Collins was a three-year veteran of the Division of Correction, a member of the Maryland National Guard and a U.S. Marine Corps veteran. He was married and the father of a five-month-old daughter when he was reported missing by his wife. The killing became a long-running cold case that left his family without answers for many years.

Is there anyone who remembers seeing Collins or his pickup in the Indiantown Road area on June 4, 2001, or who has information that could shed light on that night?
