Police: Argument between motorist, pedestrian escalates to shooting on busy Center City street

Authorities say an argument between a pedestrian and two people inside a car escalated to gunfire Wednesday night on a busy Center City street.

Officers from the Philadelphia Police Department were called to the area of 20th and Sansom street around 7 p.m. for reports of a shooting. 

Police found a 41-year-old man suffering from a gunshot wound to the torso. Police drove the victim to Jefferson University Hospital where he underwent surgery. 

Captain John Walker told reporters that investigators believe the victim was intoxicated and possibly homeless when he got in an argument with a slow-moving car on the street.

Investigators say the pedestrian began punching into the vehicle when someone inside the car fired one shot, striking the man in the abdomen. 

Authorities did not immediately have a detailed description of the vehicle.

Walker called the incident "isolated" and speculated that the shooter may have a gun permit.

Philadelphia police sources confirm a person identified himself as the shooter to police and is talking with police. There is no word on whether charges will be filed.
