The exact cause of Paul Walker’s tragic death has been determined, with TMZ obtaining a copy of the “Fast & Furious” star’s death certificate on Monday.

The document states that the Hollywood hunk, who was 40 when he met his untimely demise, passed away from "combined effects of traumatic and thermal injuries.” In essence, the star didn’t die from the impact of the car accident alone; he also burned to death from the fire that engulfed the car his friend Roger Rodas was driving.

On Rodas’ autopsy report, which was release earlier this month, the Los Angeles County Coroner said the 38-year-old driver died from "multiple traumatic injuries," but didn’t list burning as one of the reasons for his death. The 2005 Porsche Carrera GT crashed into a three trees and a lamppost on Nov. 30 just after the men left an event for Walker's charity Reach Out Worldwide.

Both men were pronounced dead at the scene and their deaths were described as “rapid” by the death certificate.

The scene of the accident, which occurred in Santa Clarita, is still being investigated. It was rumored the exotic car wasn’t working properly and that Walker decided to hop in the vehicle for a quick ride with his friend, who was behind the wheel, to figure out what was wrong.

Detective Jeff Maag told The Hollywood Reporter it could take months to figure out what happened to the vehicle to make it malfunction. Though many speculated there was something wrong with the car, Maag said that wasn’t the case. "To the extent that we can, we need to rule out mechanical failure. But the car is a mess," he said. The detective added the car was traveling at 45 mph, ruling out speeding as a cause of the crash.
