The driver blamed for causing a fiery crash last Friday on Highway 154 that killed a woman and two young children remains in critical condition, according to the California Highway Patrol.
Officers are asking anyone who witnessed the crash west of Cold Spring Bridge or has any information that may help investigators to call CHP's Santa Barbara office at (805) 967-1234.
The crash happened at about 4:45 p.m. when CHP says a Chevy Camaro driven by John Roderick Dungan, 28, of Santa Barbara, drifted into the opposite lane, crashing head-on into a Chevy Volt heading eastbound on the highway.
The driver of a GMC Yukon traveling behind the Volt tried to swerve out of the way but the two vehicles collided, causing both to catch fire.
The flames spread to nearby vegetation and burned about two acres, according to the Santa Barbara County Fire Department.
The driver of the Volt, identified as is Rebecca Vanessa Goss Bley , 34, of Solvang, and the two children in her vehicle all died at the scene.
The two people in the GMC were unhurt.
The driver of the Camaro was life-flighted to Santa Barbara Cottage Hospital and remained in critical condition as of Monday afternoon, according to CHP.
The cause of the crash, which closed a portion of Highway 154 for hours, remains under investigation.
More than 1,000 people have signed a change.org petition calling for the installment of speed monitors on Highway 154.
Organizers of the petition say they hope the monitors would decrease crashes.
