Video: Paul Walker: mourners gather at crash site to pay tribute to Fast & Furious star While the neighbourhood in which the Fast & Furious star died is known to attract street racers, accident investigators "have received eyewitness statements that the car involved was travelling alone at a high rate of speed," the Los Angeles County Sheriff's Department said in a written statement Monday. "No eyewitness has contacted the (department) to say there was a second vehicle," it said. Autopsy results could be released as early as Tuesday, said a spokesman for the Los Angeles County Coroner, as medical examiners wait for dental records to formally identify the bodies. "We're waiting for dental records," county coroner spokesman Edward Winter said. The bodies are unidentifiable. Sources: ITN/agencies
