Authorities on Saturday are looking for a big-rig driver who fled after fatally striking a tow truck operator who was changing a disabled vehicle's tire on the 5 Freeway near Castaic.
California Highway Patrol responded to the scene on the southbound 5 Freeway, about 3 miles north of Templin Highway, at around 8:15 p.m. Friday, Officer Patrick Kimball said.
Erwin Mendoza Geremillo, 47, of Castaic was assisting a motorist when a truck, which had two trailers carrying rocks, hit him, according to the Los Angeles County Department of Medical Examiner-Coroner and the CHP. Paramedics pronounced him dead at the scene of the crash.
CHP described the big rig as possibly black and red or black and white with Arizona license plates.
The incident shut down two lanes on the freeway, which reopened just after midnight.
