Authorities worked Saturday to determine why a man ran into traffic and was struck and killed by a vehicle on the eastbound Pomona (60) Freeway near the Orange (57) Freeway interchange in Diamond Bar.
California Highway Patrol officers were called at 9:30 p.m. Friday and responded to the scene along with Los Angeles County firefighters and located the victim, who was pronounced dead at 9:50 p.m., according to CHP Officer Patrick Kimball.
A preliminary investigation determined a vehicle was either involved in an crash or became disabled in the No. 1 lane of the freeway and the man exited the vehicle and began running in traffic, then was struck, Kimball said.
The driver who struck the man stayed at the scene and cooperated with the investigation.
The name of the victim was not available.
