Sean Franklin, 37, was found dead in his silver Pontiac Grand Prix in Chester’s Highland Gardens neighborhood on the evening of August 31, 2005. He had sustained a single gunshot wound to his back; the Delaware County Medical Examiner ruled his death a homicide. Franklin ran a commercial cleaning company and was an alumnus of Temple University.

Investigators concluded an argument occurred shortly before the shooting and that Franklin was shot as he attempted to drive away. The case remained unsolved for years. In February 2012 authorities arrested 26-year-old Ronier Kennedy of Chester and charged him with Franklin’s murder, along with related counts of aggravated assault and simple assault; Kennedy was also charged in an unrelated 2007 attempted murder.

Anyone who knew Franklin, saw him in Highland Gardens that night, or has information about the argument or the vehicle is asked to come forward.
