There may be some answers surrounding the crash that took actor Paul Walker and driving pal Roger Rodas' lives on Saturday, Nov. 30. 

CNN reports that drag racing may have caused the deadly crash, and that a second vehicle may have been involved. Los Angeles County Sheriff Sgt. Richard Cohen told the news agency that investigators received a phone tip suggesting another car was at the scene. 

Rodas and The Fast and the Furious star -- 40 years old at the time of his death -- were riding in a red 2005 Porsche Carrera GT, and Rodas is believed to have been driving at the time. 

"Naturally, from an investigative standpoint, we need to find out if that is one of the issues," Sgt. Cohen said. 

Investigators are also looking into the possibility that another car -- drag racing or not -- veered in front of the Porsche, causing it to hit the light post. 

Tire skid marks near the crash site appear to be in the shape of doughnut spins and are being investigated at this time. 

Walker is survived by his 15-year-old daughter Meadow, his parents, Paul and Cheryl, his two brothers, Cody and Caleb, and his sister, Ashley.
