Two people were killed in a crash involving two vehicles and a bicycle in Malibu on Friday, according to the Los Angeles County Fire Department.
The collision occurred shortly after noon on the southbound Pacific Coast Highway at Trancas Canyon Road, said County Fire Inspector Gustavo Medina.
He confirmed two people were pronounced dead at the scene. A third person suffered minor injuries and a fourth was being airlifted to a hospital, according to Medina.
Investigators learned that a gray Mercury minivan was driving westbound along the highway at a high speed when it attempted to pass another vehicle, the Los Angeles County Sheriff's Department said in a news release.
While doing that, the driver of the minivan lost control and went over the center divider — slamming head-on into a red Dodge Ram truck, the department said.
Authorities later said the people killed were the drivers of the van and truck while a bicyclist riding nearby sustained minor injuries from flying debris at the scene and was taken to a hospital in an ambulance.
A passenger in the truck was airlifted in stable condition, sheriff's deputies said.
No other information about the victims has been released.
Sky5 video over the scene showed two vehicles -- a white minivan and a red pickup truck -- with extensive front-end damage, indicating a likely head-on crash. Debris was strewn about the roadway, and a tire lay on the middle of the highway.
White sheets covered the front of both vehicles.
Firefighters appeared to be working to get one of the victims out of the truck, according to the aerial footage.
The southbound PCH and one northbound lane of the highway have been closed until further notice, said Los Angeles County Sheriff's Sgt. Gonzalez.
The highway runs east to west in the portion where the collision occurred, and Gonzalez initially described the eastbound lanes as the ones that were fully closed.
Traffic was at a crawl in the area as of 1:30 p.m., the video showed.
