Dewayne Johnson was 29 when he was shot and killed in Philadelphia on July 20, 2009. His death came during a violent summer for the city, a year in which a large share of murder victims were between 18 and 34 and firearm-related killings were widespread.

No suspects have been publicly identified and no arrests have been announced, and the case has since gone cold.

Did anyone in the Philadelphia community at that time know Dewayne, his routine, or have information that could help reopen leads in this unsolved homicide?
