Harley "Hunter" Reimes was a private detective that grew too attached to his case. He investigated the rape and murder of a young woman and knew he had found his man, but he lacked the evidence to nail him. When he heard that his suspect had commited another rape he took the law into his own hands and put a stop to him, the smoking barrel way. Unfortunately for Reimes there was plenty of evidence around to convict him to 10 years in prison.

A private detective won't have a great time in a prison together with the convicts he helped put there, so applying to the Gangstas was his desperate chance of getting out.
