As speculation continues to mount over what will happen with Paul Walker's ongoing film projects after his Saturday afternoon car crash, CNN is now reporting that drag racing may have played a part in his and business partner Roger Rodas' untimely deaths.

The Los Angeles County Sheriff's Department released a statement on Sunday afternoon claiming that speed was a factor in the crash of the Porsche Carrera GT with Rodas behind the wheel, though specific details were still being investigated. The sheriff's department received a tip on Sunday that another car may have been on the scene of the accident, which has now led them to investigate whether Rodas and Walker were drag racing in the moments immediately prior to crashing head-on into a light pole.

Investigators are now looking into the possibility of any sort of racing being involved, as well as whether another car had somehow veered in front of Rodas' Porsche. They are also investigating multiple skid marks in the area that are indicative of 'doughnut spins,' though said marks may be old—Hercules Street in Santa Clarita where the accident took place is known for being a popular stretch for car racing, and has an inspired a police crackdown in the last few years. Officials say that it will take quite some time before it's evident just how fast the Porsche was travelling before it collided.

Meanwhile, as the cliche states, the show must go on, and those in production with Walker are doing just that. The Walker-produced independent drama Hours, starring Walker as a father whose child is born during Hurricane Katrina, will stick to its December 13th release date. Producer Peter Safran stuck his foot in his mouth when speaking to The Hollywood Reporter, stating "He really looked to this movie to show people that he is an actor. He was looking for something to showcase his acting skills, which he so rarely had the chance to do." The film will be released simultaneously in theaters and on demand.

Walker was also in production on Fast & Furious 7, which had taken a short Thanksgiving break, but was in the middle of ongoing filming in Atlanta. Walker and co-stars Tyrese Gibson, Vin Diesel and Dwayne Johnson were all set to return to shooting today. Universal and director James Wan will now have to figure out how to best deal with Walker's role as police officer turned car thief Brian O'Conner, as Walker had not completed his scenes of principal photography. Though the bulk of the film was already shot, Walker and the crew were set to film a few scenes in Abu Dhabi in the new year, once they wrapped up in Atlanta. The film was already shooting on an expedited schedule in order to make a July 11, 2014 release date.
