Lawrence Mouzone, 24, was murdered in Philadelphia on August 3, 2011. His death came during an especially violent month for the city, when more than 50 people were reported killed in August 2011, and it was one of many homicides that contributed to heightened fear and grief across affected neighborhoods.

No arrests have been announced and the case remains unsolved. Mouzone’s death is described as part of a broader pattern of violence in the city at that time, and his family continues to live with the unresolved loss.

If anyone knew Lawrence, saw something related to his death on or around August 3, 2011, or has information that could help investigators, please come forward.
