LOS ANGELES (AP) — "Fast & Furious" star Paul Walker was killed by impact and fire in a crash that occurred while he was a passenger in a Porsche driven by his friend, according to an autopsy released Wednesday
Walker died Saturday when the high-performance car smashed into a light pole and tree, then exploded in flames.
The 2005 Porsche Carrera GT was driven by Roger Rodas, who was killed by the impact alone, according to the autopsy released by the Los Angeles County coroner's office.
Results of toxicology testing will take another six to eight weeks.
Sheriff's investigators were still trying to determine what caused Rodas to careen out of control. They have said speed was a factor in the crash about 30 miles northwest of downtown Los Angeles.
Meanwhile, Universal Pictures has shut down production "for a period of time" on "Fast & Furious 7."
The studio announced Wednesday it would "assess all options available to move forward with the franchise."
The film was on break for the Thanksgiving holiday when Walker died. Shooting had been planned to resume Monday in Atlanta.
While much of "Fast & Furious 7" has been filmed, it is far from complete.
Universal is scheduled to release the film in July.
Walker starred in all but one of the six "Fast & Furious" blockbuster films that glorified fast cars and dangerous driving.
