The hunt continues for a driver who fatally shot a Philadelphia man several times during a road-rage episode in Cheltenham on Monday night, authorities said Friday.

Investigators have determined that the shooter drove a black or dark-colored sedan and fled after shooting Rithina Torn, 29, of Olney, multiple times around 9:30 at Dewey Road and Front Street. Police say Torn got out of his car, walked to the shooter's car, and was shot.

Authorities said they also were seeking two other motorists who drove through the intersection immediately after the shooting.

On Friday, the Montgomery County District Attorney's Office released two short, grainy surveillance footage clips that show the shooter's car driving through the dark with its high-beam lights on. Authorities did not specify the car's possible make or model.

Before the shooting, authorities said that the shooter drove west from Cheltenham Avenue onto Bellmawr Avenue and Dewey.

Torn died of his injuries at Einstein Medical Center.

Authorities ask that anyone with information about the shooting call Cheltenham police at 215-885-1600 or the Montgomery County Detective Bureau at 610-278-3368.
