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.

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.
