Marvin Pierson was 15 when he was shot and killed at Ralph Dills Park, 6300 San Julian Street in Paramount, California, on July 15, 2007 at about 5:30 p.m. He was pronounced dead at the scene. Family members and community groups held a vigil after the killing.

Investigators concluded Marvin was a victim of gun violence. There were no immediate arrests or suspects, and the investigation faced challenges from a lack of witnesses and concrete evidence. Over the years the case has seen little progress and the person or persons responsible have not been apprehended.

Who remembers being at or near Ralph Dills Park that evening or has information that could help bring those responsible to justice?
