Paul McKernan, 27, was fatally shot on August 15, 2014, outside a Chinese restaurant in the Overbrook section of Philadelphia after an argument turned violent. He worked as an electrician and was pronounced dead at the Hospital of the University of Pennsylvania after suffering a gunshot wound to the throat. Surveillance footage captured his final moments, though the shooter is not visible on the tape. Police have been reviewing nearby camera footage and asked anyone with information to come forward.

McKernan’s case is complicated by earlier legal history: he was convicted in 1998 of first-degree murder for the killing of his roommate Mark Gibson with a baseball bat, a conviction that produced a mandatory life sentence without parole. Reports say a federal appeals court overturned that conviction in 2017, citing concerns about the trial judge’s impartiality and remanded the case for retrial; whether the retrial would proceed was under review. If anyone knew McKernan, saw activity around the restaurant that night, or has information about the shooting, please share what is known with investigators.
