Drag racing may have been involved in the fiery crash that killed Fast and Furious actor Paul Walker on Saturday, an investigator said Monday.
Investigators got a phone call tip Sunday suggesting that another car was at the scene when the 2005 Porsche Carrera GT, driven by Walker's racing team partner, slammed into a light pole and burst into flames, Los Angeles County Sheriff's Sgt. Richard Cohen told CNN.
"Naturally, from an investigative standpoint, we need to find out if that is one of the issues," he said.
Even if drag racing was not involved, investigators are looking at the possibility that another car veered in front of the Porsche and caused the crash, Cohen said.
