CONTRA COSTA COUNTY, Calif. -- One person was killed and three others were injured in a head-on crash Wednesday afternoon on Vasco Road, about a mile-and-a-half from Byron.

The crash, which also involved a third vehicle, happened around 2 p.m., according to Contra Costa County Fire Protection District Spokesperson Steve Hill.

The road south of Camino Diablo was still shut down in both directions just after 3 p.m. Hill said at least two helicopters and multiple ambulances were necessary to transport victims.


The initial report said a van collided head-on with a pickup truck. A public information officer with Con Fire originally told ABC7 News 10 people were injured, but that has since been corrected.

Two people had to be extricated from the vehicles; one at 2:30 p.m. and the other at 2:47 p.m.

The victims were transported to John Muir Medical Center in Walnut Creek, including a 31-year-old man and a 40-year-old.

Hill said it's likely the road will remain closed into the evening commute.
