Adrian Parlette, 23, was found dead at his home on Pauline Avenue in Columbus, Ohio, on June 5, 2003. He had suffered a fatal gunshot wound and the Columbus Police Department classified the case as a homicide.

The Ohio Attorney General’s Office and the Columbus Police Department have asked the public for information, and the Ohio Bureau of Criminal Investigation lists the killing among unsolved homicides it is trying to publicize. Authorities say there have been no significant leads that resulted in an arrest or conviction.

Anyone with information about what happened to Adrian is asked to contact local law enforcement or submit a tip through the Ohio Attorney General’s cold case website.
