PHILADELPHIA (CBS) - A deadly hit-and-run in Kensington has police baffled.

No evidence was left at the scene, just the body. Police didn’t know he had been struck by a car until they got a call from the medical examiner’s office.

A small piece of police caution tape remains on the ground near American Street and Lehigh Avenue in Kensington. It’s where police say paramedics found the 4th person this year to die from a hit-and-run accident. At about 5 a.m. on Saturday, someone called 911 to report a man on the side of the road.

“He had two broken femurs and a shoulder,” said Capt. John Wilczynski with the Philadelphia Police Accident Investigation Division

Three hours after being transported to the hospital, the victim was pronounced dead. The medical examiner’s report confirmed the victim died from injuries he sustained from being hit by a car.

Police say the Rite Aid and Wendy’s across the street don’t have any surveillance video. There were no signs of skid marks on the road, and no physical evidence left behind.

“Unfortunately we don’t have any leads at this time,” said Capt. Wilczynski. “We’re hoping somebody at 5 o’clock in the morning maybe saw it.”

If you have any information at all, police want to hear from you. You can call their accident investigation division at (215) 685-3180.
