The actor, 40, died Saturday afternoon when a car he was in crashed and exploded in Santa Clarita, Calif. The driver also was killed.
“When they arrived, deputies found the vehicle engulfed in flames,” the police said in a statement. “The Los Angeles County Fire Department responded, extinguished the fire and subsequently located two victims inside the vehicle. The victims were pronounced dead at the scene.”
“This is an ongoing investigation,” Deputy Heischuber of the Santa Clarita Valley Sheriff’s Station tells PEOPLE. “A solo car crash occurred about 3:30 p.m. in the city of Santa Clarita, on the outskirts of Valencia. A 911 call came in from a bystander.”
A Tweet from Walker’s verified account later read: “It’s with a heavy heart that we must confirm Paul Walker passed away today in a tragic car accident.”
At the time of his death, the actor had been “attending a charity event for his organization Reach Out Worldwide,” according to a post on his official Facebook page. “He was a passenger in a friend’s car, in which both lost their lives. We appreciate your patience as we too are stunned and saddened beyond belief by this news. Thank you for keeping his family and friends in your prayers during this very difficult time. We will do our best to keep you apprised on where to send condolences.”
