PHILADELPHIA (CBS) - A SEPTA worker has died after being shot several times while on his way to work early Thursday morning.

The shooting happened at about 5:30 a.m. at 71st Street and Elmwood Avenue in Southwest Philadelphia.

Investigators say 52-year-old Aaron Hayes was heading to work at the Elmwood and Island Station when he was shot three times, including once in the head, neck and arm.

Hayes was rushed to the Hospital of the University of Pennsylvania where he succumbed to his injuries.

Authorities say they believe Hayes was targeted; the shooting suspect was a white male and the getaway car, a black and gray Mitsubishi, was driven by a white female.

So far, no one is in custody and police have not determined a motive. Police are analyzing surveillance footage from cameras at nearby establishments.

Earlier Thursday afternoon, Captain James Clark of the Philadelphia Police Department said Hayes was on life support and was not expected to survive his injuries.

Anyone with information is urged to contact police. Homicide detectives are investigating.
