LA police reviewing the death of the Fast & Furious star in a car crash have ruled out theories another vehicle was involved

Police in Los Angeles have rebutted a so-called "second car" theory in the tragic death of Fast & Furious star Paul Walker, according to The Wrap.

Walker, 40, died on Saturday afternoon when the limited-edition Porsche he was travelling in crashed and burst into flames in Valencia, Santa Clarita. Some US reports have suggested authorities received a tip on Sunday suggesting Walker and driver Roger Rodas were drag racing against another vehicle. But the Los Angeles Sheriff's department said yesterday that there was no evidence a second car was involved and authorities were focusing on the speed of the Porsche prior to the crash. An autopsy is expected today.

Walker's sister angrily denied there was any suggestion of drag racing and said the family had been left devastated by "lies" in an interview with the Mail Online. Ashlie Walker, 37, said: "They were absolutely not racing, that's a complete lie. It hurts us when we hear these lies and it makes our grief worse and more painful. These are irresponsible allegations and people are trying to make out speed and racing was the reason for his death when it was just a terrible accident."

A police spokesman told The Wrap the investigation would involve officials writing a traffic report, photographing the scene, measuring skid marks and the location of debris, examining on-board car computer data which might indicate speed and looking for evidence of paint transfer which might suggest a collision with other objects or cars.

Walker's family issued a statement yesterday thanking fans and friends for an "outpouring of love and goodwill" in the wake of the actor's death and asking for donations to be made to his charity Reach Out Worldwide.

"It's comforting for them to know that the son, brother, and father they love so much is equally adored, respected, and appreciated by so many," the statement read. "Paul founded the organisation with the genuine desire to help others, and it's important to his family to keep his memory alive through ROWW."
