Edward Robinson was 30 when he was found dead from a gunshot wound on December 29, 1990, at 1325 E. Livingston Avenue in Columbus, Ohio. The homicide remains unsolved and is listed in the Ohio Attorney General’s database of unsolved homicides. Initial investigation by the Columbus Police Department did not identify suspects and the case went cold.

Robinson’s death is one of roughly 150 unsolved cases among about 500 homicides in Columbus since 1980, a backlog investigators say is hampered by the passage of time, lost evidence, and fading witness memories. Authorities note that advances such as DNA testing have helped other cold cases and that the Columbus Police Department and the Ohio Bureau of Criminal Investigation continue to review old files in hopes of new leads.

Anyone with information about Edward Robinson or the night of December 29, 1990, is urged to contact law enforcement or submit an anonymous tip to help bring answers to his family and friends.
