Marquis J. Cerda, 31, was killed in Baton Rouge on July 24, 2009. The Baton Rouge Police Department’s Homicide Division processed the scene and interviewed witnesses, but the case went cold for years with no publicly known suspect and no arrest announced for a long period. The prolonged lack of leads and arrests left Cerda’s family without answers as the investigation remained open.

If anyone has information about Marquis Cerda, his activities in Baton Rouge in July 2009, or the events surrounding that day, please share what is known with investigators.
