San Diego police are investigating a hit-and-run collision involving a pedestrian struck by two vehicles near Alvarado Hospital.
A woman suffered life-threatening injuries while walking on Alvarado Road, east of College Avenue and south of Interstate 8 shortly after 9 p.m. Wednesday.
The victim, described by San Diego police as 44 years old, was first struck by an 2010 Nissan Frontier, according to San Diego police Officer John Buttle.
That driver stopped after the crash.
The woman had been walking down the middle of the street and was dressed in all black, so it was unclear if she had stepped into the pickup truck's path or its driver didn't see her in the roadway, according to the officer.
The impact of the crash threw the woman into the westbound lane, where evidence suggested she had been hit while on the ground by a second vehicle that did not stop, Buttle said. A description was not immediately available.
The victim was taken to a hospital, according to the officer.
