Police on Monday identified the man whose body had been dragged Thursday onto a Holmesburg sidewalk and who was left for dead as Brian Jones, 40, of Bucks County.

Jones, of the 200 block of Stanford Road in Fairless Hills, had been shot in his left rear shoulder, police said. Medics who were called to the scene following a report of an unconscious man on the sidewalk, performed CPR and tried to save him, but couldn't. The victim was pronounced dead at the scene at 6:45 p.m. Thursday.

Police said surveillance video showed two men and a woman dragging the victim out of a building that houses a dental office and apartments, and leaving the man's body on the sidewalk.

No arrests have been made in this homicide, but police said Monday that the investigation has revealed that the motive behind the shooting was an argument.
