Autopsies began on Paul Walker and Roger Rodas’ bodies Tuesday, but they were so badly charred that the coroner could still not positively identify the “Fast & Furious” star and the race car driver after their tragic and sudden death in a fiery crash on Saturday.

"We have not positively identified them yet, but the investigators will do X-rays and check to see if the damage actually matches the preliminary findings," Los Angeles County Coroner spokesman Ed Winter told the New York Daily News.

"We'll check to see if we can tell whether they died of blunt force trauma or smoke inhalation or thermal burns," he said. "We probably can do toxicology tests as well. That would be part of the full autopsy."

It was earlier reported that dental records would be needed to identify the remains, and on Tuesday afternoon coroner officials said a forensic odontologist was called.

Walker, 40, and Rodas, 38, met a grim parallel to his movie franchise when a 2005 Porsche Carrera GT driven by Rodas hit into a tree and then flames engulfed the exotic sports car in Santa Clarita, Calif. It’s been rumored the men were drag racing and although authorities said speed was a factor in the accident, witnesses reported the car was traveling alone and not part of a street race.

"If I had to guess, I'd say (Roger) put his foot into it just to feel the power a little bit, and the car did something unnatural," the race team source said. "It was a nervous, twitchy car, and I really believe Roger's last thought was: 'What just happened?'"

Walker leaves behind a daughter, Meadow Rain, 15. The star had already began work on “The Fast and the Furious 7” when he passed away.

A son, 8, daughter and wife survive Rodas.
