While the neighbourhood where Fast & Furious star Paul Walker died in a fiery crash is known to attract street racers, law enforcement officials do not believe the Porsche he and a friend were riding in had been racing another car.
Accident investigators "have received eyewitness statements that the car involved was traveling alone at a high rate of speed," the Los Angeles County Sheriff's Department said in a written statement. "No eyewitness has contacted us to say there was a second vehicle."
Mr Walker and his friend and fellow fast-car enthusiast Roger Rodas died on Saturday when Mr Rodas' 2005 Porsche Carrera GT smashed into a light pole and tree, then exploded in flames. The posted limit was 72.4kmh.
The two had taken what was expected to be a brief drive away from a charity fundraiser and toy drive at Mr Rodas' custom car shop in the Southern California community of Valencia, about 48km north-west of Los Angeles.
Mr Walker's publicist said the action star was the passenger, reports The Straits Times.
