Police were searching Saturday for drivers involved in three fatal hit-and-run accidents that left two men and a woman dead in Philadelphia and South Jersey.

The first fatality happened about 4:45 a.m. Friday in Cherry Hill, where a man was walking across Route 38 in a marked crosswalk near Chestnut Street when a car hit him in the right eastbound lane, police said. Police did not immediately identify the victim.

The second accident occurred just before 7:30 p.m. Friday in Blackwood, Gloucester Township, authorities said. There a woman was struck while walking on the 2000 block of College Drive, off Blackwood Clementon Road, police said. By the time officers arrived, they said, the driver had fled and the woman was unconscious.

She was pronounced dead at the scene. Authorities have not released her name pending family notification.

Police interviewed witnesses and viewed surveillance footage from the area, they said, and eventually located what they believe to be the vehicle involved in a nearby neighborhood.

In the third fatality, a man in his mid-30s was struck by a dark green Pontiac minivan with heavily tinted windows at 2:46 p.m. Saturday on the 700 block of West Berks Street in North Philadelphia. Medics transported him to Temple University Hospital, where he was pronounced dead at 3:19 p.m., police said. The victim’s identity was not released.

The van was last seen driving east on Berks, police said.
