On the night of Sunday, July 3, 2016, 16-year-old Asir Brown was fatally shot while attending a backyard barbecue at his aunt’s home on the 1800 block of South 31st Street in Philadelphia. A dark-colored car pulled into the alley behind the house and at least one person in the back seat opened fire on the teenagers gathered in the yard; investigators later determined 19 shots were fired from two different firearms. Asir was struck once in the back and was taken to Children’s Hospital of Philadelphia, where he died the following morning.

Police treated the incident as a homicide and searched for two gunmen. Detectives said the shooting may have stemmed from a dispute between teenagers from different parts of the city, possibly over a girl. A reward was offered for information leading to an arrest and conviction, but no arrests have been made and the case remains unsolved.

If anyone was at that barbecue or has information about the dark-colored car, the shooters, or the dispute mentioned by detectives, please come forward.
