On June 29, 2016, 13-year-old Christopher Chris Mackey was killed in Germantown, Philadelphia, after a group of friends found a loaded revolver inside an abandoned house on East Walnut Lane. Believing the gun was jammed, a 15-year-old friend pulled the trigger; the weapon discharged and a single bullet struck Chris in the face, causing a fatal injury. The teens also found stolen jewelry in the vacant home.

Two teenagers were taken into custody after the shooting. The 15-year-old who fired the weapon was charged with involuntary manslaughter; a second teen present faced lesser charges. Authorities described the shooting as a tragic accident.

Family and friends held an emotional vigil, remembering Chris as a kind young man and calling for an end to gun violence and for gun owners to secure their weapons. If anyone knew Chris or has information about how the gun ended up in that vacant house, please share what you know.
