Philadelphia district attorney Seth Williams tells Fox 29 police are still investigating the killing of a man who said ex-NFL star Marvin Harrison tried to kill him in 2008, as well as that original 2008 shooting. Williams told Fox 29 that police are actively investigating an April 2008 shooting that allegedly involved Harrison and the late Dwight Dixon. Dixon died in September 2009 after he was shot in July 2009 several blocks away from a sports bar owned by Harrison in Philadelphia. "We are continuing to investigate all angles and all open investigations and leads regarding a shooting that happened in April 2008 between Mr. Dixon and Mr. Harrison, and employees of Mr. Harrison, and others,” Williams said.
