Police are trying to identify a woman who died after witnesses said she was struck by three cars on North Broad Street early Friday.
Just before 5 a.m., the woman - who was topless - walked into traffic near Belfield Avenue, police said.
Witnesses told police that one car hit the woman with such force that she was thrown in the air, then two other vehicles hit her.
Capt. John Wilczynski of the Accident Investigation Division said Friday afternoon that investigators were unsure how many cars struck the woman, who appeared to be in her mid-40s, or why she was partially clothed.
