Quincy Long Jr. was 14 when he was fatally shot on July 1, 2022, in Upper Darby, Pennsylvania. Quincy, an honor roll student at Beverly Hills Middle School, was in the basement of a home on Ruskin Lane with a group of friends making music videos when one of the children produced a firearm. The gun was passed around for photos, and it discharged; Quincy was struck in the chest and died.

Police identified 16-year-old Jermaine Young of Upper Darby as the person holding the gun when it fired. Young initially fled the scene and later surrendered to authorities. He was charged with third-degree murder and other offenses and was arraigned and placed in a juvenile facility.

Family and friends held a vigil to remember Quincy, and local officials including members of the Upper Darby Council attended, calling for justice and urging people to put down guns. Anyone who was present that day or has information about the shooting is asked to come forward.
