A vehicle slammed into a woman who was standing over a motorcyclist that was stuck under a pickup truck and died after a traffic collision she had just witnessed in Lancaster early Sunday morning, the Los Angeles Sheriff's Department said.
Four different vehicles were involved in the fatal pile-up in the area of 15th Street East and Avenue I, authorities said.
A red pickup truck ended up on top of a motorcycle after the two collided at around 1:30 a.m. A deputy heard the crash and ran over along with other good Samaritans and tried to help the motorcyclist, according to LASD.
Another vehicle then came through the intersection and slammed into the woman then crashed with two other vehicles, authorities said.
Police said the woman is in critical condition.
The motorcyclist, a Lancaster man in his mid-30s, was pronounced dead at the scene, Los Angeles County Department of Medical Examiner-Coroner Lt. Larry Dietz said. His identity was withheld Sunday pending notification of his family.
It is unclear whether drugs or alcohol were involved in the incident.
No further details were immediately available.
