William Allen was 37 when he was killed in Detroit, Michigan on November 25, 2012. His death occurred near Roselawn Avenue during a year that saw more than 400 homicides in the city, part of a sharp rise in violent crime that strained local law enforcement.

Allen’s killing remains an open and unsolved homicide. The Detroit Police Department later formed a Cold Case Unit and worked with community groups to solicit tips, but investigators say a lack of evidence and limited witness cooperation have impeded progress. No arrests have been announced and no suspects have been publicly identified.

If anyone has information about William Allen’s death or remembers that area around Roselawn Avenue in late November 2012, please come forward and contact investigators.
