Authorities are searching for a hit-and-run driver that fled a fatal crash involving multiple vehicles in Diamond Bar early Thursday morning.

The chain-reaction collision began about 12:20 a.m. when a two-vehicle crash was reported on the northbound 57 Freeway connector road to the eastbound 60 Freeway, California Highway Patrol Sgt. Louis Borunda said.

As authorities were in route, they were told one victim may have been ejected at the scene.

They arrived to find a 49-year-old Moreno Valley woman down in the roadway, officials said. She was pronounced dead at the scene.

Investigators believe the woman may have pulled over after the initial collision and was struck in a second crash.

As she was possibly exiting her vehicle, Borunda said, she may have been hit by a third vehicle.

“That vehicle is not on scene, so we’re looking at it as a hit-and-run,” Borunda said.

No other injuries were reported in the incident. The victim's identity was not released pending notification of family by coroner's officials.

The hit-and-run vehicle was described as a silver, 2011 or newer Chevrolet Cruze, CHP officials said.

Anyone with information was asked to contact authorities at 626-338-1164.

The northbound 57 Freeway was closed at Grand Avenue during the investigation.  All lanes have been reopened, video from the scene showed.
