The victim of a fatal 5 Freeway crash in Castaic has been identified, officials said.

Sergio Martinez, 35, of Grand Junction, Colorado, died at the scene of a 5 Freeway crash, according to Sarah Ardalani a spokesperson with the Los Angeles County Medical Examiner-Coroner’s Office.

Around 5:40 a.m. Wednesday, firefighters received reports of a traffic collision involving fire and victims trapped on the northbound 5 Freeway south of Parker Road, said Michael Pittman, dispatch supervisor with the Los Angeles County Fire Department.

“When we got on scene, they confirmed a small pick-up truck was under the semi and was fully involved,” Pittman said.

The semi also caught fire as a result of the crash, according to officials.

Due to the driver suffering from major burns, it is unclear if officials will be able to say if drugs or alcohol played a role in the crash, said Officer Josh Greengard, spokesperson for the California Highway Patrol Newhall Office.

Firefighters were able to have both vehicle fires extinguished by 5:58 a.m., according to officials.

Officials with the California Highway Patrol were at the scene to investigate the crash.

“The pickup truck was lodged under the truck-tractor combination and burst into flames,” Greengard said. “The pickup truck had a solo driver, who sustained fatal injuries.”

The cause of the crash is still being investigated, according to officials.
