Fabian Johnson, 18, was found dead in Tacony Creek Park in Philadelphia in the fall of 2010 after a group of children discovered his body on a Saturday afternoon. A resident of the Feltonville neighborhood who lived on Rorer Street, Johnson had been shot in the back of the head in what police described as an execution-style killing.

At the time his body was identified, investigators were awaiting autopsy results to establish the approximate time of death. Police initially made no arrests and the shooting was listed among the city’s homicides for 2010. There have been no public announcements of suspects or arrests since and the case remains unresolved.
