LOS ANGELES (AP) - An autopsy shows "Fast & Furious" star Paul Walker was killed in a car crash by the combined effects of the impact and subsequent fire.
Walker, a passenger in the car driven by his friend and financial adviser Roger Rodas, died Saturday when the 2005 Porsche Carrera GT smashed into a light pole and tree then exploded in flames.
The Los Angeles County coroner's office released the autopsy results Wednesday. The report also says Rodas was killed by the impact. Walker starred in all but one of the six "Fast & Furious" blockbuster films that glorified fast cars and dangerous driving.
Sheriff's investigators are still trying to determine exactly what caused Rodas to careen out of control. They have said speed was a factor.
Universal Pictures has shut down production "for a period of time" on "Fast & Furious 7" following the death of Walker.
The studio announced Wednesday that the film will shut down "for a period of time so we can assess all options available to move forward with the franchise."
The seventh installment of the street racings series had begun shooting in September. When Walker died in a fiery car crash Saturday, the film was on break for the Thanksgiving holiday.
Shooting had been planned to resume Monday in Atlanta, but production was put on hold following Walker's death.
While much of "Fast & Furious 7" has been filmed, it is far from complete.
Universal is scheduled to release the film in July.
