UPDATE (5:40 p.m.): Police report that the woman has a brain injury and is in “very critical” condition. She is 23 years old, according to CBS Philly. Police are still searching for the car that hit the woman and fled.

Earlier: Police are looking for witnesses to a hit-and-run accident that left a woman face down and unconscious in the middle of 48th Street between Pine and Osage early Sunday morning.

A neighbor who lives near the scene says that she woke early this morning, around 2:30 a.m., to people screaming outside her window and saw a woman lying in the middle of the street. The neighbor said the woman looked unresponsive and it looked like she had head trauma.

“It looked like she either had on flats or no shoes at all and only a cell phone (no purse, etc.),” the neighbor wrote by e-mail this morning.

“I heard a very loud and constantly pacing man saying that he just found her like that and almost drove over her,” she wrote. “He stayed until the last cop left the scene.”

Police tweeted that the woman was in critical condition and that they are looking for witnesses. If you saw something call 686-TIPS or write tips@phillypolice.com.
