Los Angeles: Investigators sought to determine the cause of a fiery crash that killed "Fast & Furious" star Paul Walker while the actor's fans erected a makeshift memorial Sunday near where the Porsche he was riding in smashed into a light pole and tree.
The Los Angeles County Sheriff's Department said speed was a factor in Saturday's one-car crash, though it will take time to determine how fast the car was going.
Because Walker is so closely associated with the underground culture of street racing portrayed in the popular "Fast & Furious" film franchise, the fatal accident had an eerie quality — a tragic end for a Hollywood hero of speed.
