A news report blaming Paul Walker's fatal car accident on excess speed alone has been reported as false.
According to TMZ, multiple law enforcement sources have said the claims made in a news story by The Associated Press are incorrect.
AP earlier reported that investigators have already concluded there was no evidence of the Porsche Carrera GT driven by Walker's friend Roger Rodas, having mechanical problems at the time of the crash.
The AP news report suggested that Rodas was simply driving too fast and also claimed that the investigation ruled out debris in the road as a possible cause for the car losing control.
TMZ however reports that according to law enforcement sources "the investigation is ongoing and no determinations have been made regarding the cause."
The L.A. County Sheriff's Dept. has summoned Porsche engineers from Germany to examine what remains of the engine, brakes and tyres of the vehicle, in an effort to determine the cause of the accident.
Earlier this week, the actor's family refuted claims that speed was a factor in the accident, and stated their belief that plastic road markers may have been responsible for the crash that killed Walker. Stunt experts said the vehicle may have hit the markers, called Bott's Dots, and careered out of control.
Walker died following the crash on November 30, when the vehicle careered into a tree and caught fire.
The Fast and Furious star died from the combined effect of severe burns and injuries resulting from the crushing initial impact of the high-speed car crash, an autopsy revealed.
According to authorities, Walker was still alive when the car burst into flames, while Rodas was killed on impact.
Walker was laid to rest on Saturday (14 December) at Forest Lawn Memorial Park, in a private funeral service with close friends and family attending.
