Walker died on Saturday afternoon, Ame Van Iden told the Associated Press.

A statement on the actor's Facebook page said he was a passenger in a friend's car, and that Walker was in the area to attend a charity event for his organization Reach Out Worldwide.

"We... are stunned and saddened beyond belief by this news," the statement said.

The Los Angeles County Sheriff's department said that deputies found a car engulfed in flames when they responded to a report of a collision in the community of Valencia. Two people who were found in the car were pronounced dead at the scene.

The Santa Clarita Signal reports a red Porsche crashed into a light pole and tree and burst into flames.

Walker was working on "Fast & Furious 7" at the time of his death. He also starred in the suspense drama, "Hours," which is set for release this month.
