Marvin Edward McClain was 23 when he was shot and killed on the evening of Sunday, November 29, 2015. Officers found him on the 200 block of Denison Street in Baltimore with multiple gunshot wounds; emergency medical personnel could not save him.

His death came during a year of sharply rising violence in the city, one of more than 340 homicides in 2015. Investigators faced limited leads and a lack of cooperative witnesses, and no arrests or publicly identified suspects have been announced. The case remains open but has grown cold without new information.

If anyone knew Marvin, saw activity on Denison Street that night, or has information that could help the investigation, please come forward.
