The incident happened around 7:30 a.m. in the 2500 Block of East Avenue I in Lancaster, according to Lancaster Station deputy Miguel T. Ruiz.
The woman was attempting to walk southbound from the north sidewalk to a bus stop on the south side of the roadway, when she was apparently hit by a vehicle that was exiting a trailer park turning left onto eastbound Avenue I, Ruiz stated.
The driver left the scene without stopping.
The elderly woman suffered serious head trauma and was transported to Antelope Valley Medical Center where she remains on life support.
Her name is being withheld pending next of kin notification.
The investigation is ongoing and no further suspect information can be released at this time, Ruiz said.
