Christopher Jones was 23 when he was fatally shot on July 13, 2011, on the 1900 block of West Cumberland Street in Philadelphia. His death was one of many homicides that year, a reflection of the city’s struggle with gun violence.

The case remains unresolved and authorities have urged anyone with information to come forward. Few other details are available about the shooting or possible suspects.

If anyone knew Christopher, was in that neighborhood that evening, or has information about the incident, please share what you know with investigators.
