William Chaffin, known to family as Lil Will, was a 14-year-old Black boy from McKeesport, Pennsylvania, who was shot dead inside a house on Ridge Street the afternoon of April 25, 2017. The shooting occurred shortly after 2:30 p.m.; emergency responders found him on the first floor with a gunshot wound to the chest and he was pronounced dead at the scene. The Allegheny County Medical Examiner ruled the death a homicide.

Investigators from McKeesport police and the county homicide unit questioned a 19-year-old who had been in the house with William; early reports said everyone involved had been identified. William’s mother and grandmother publicly disputed that account and sought fuller answers about where the gun came from and who had control of it.

The case was referred to the Allegheny County District Attorney’s Office for charging review and, as reported at the time, no charges had been filed.
