Paul Walker's death may have been caused by a car malfunction, according to reports.
The 40-year-old actor lost his life on Saturday when the red 2005 Porsche Carrera GT he was a passenger in hit a utility pole and burst into flames in Santa Clarita, California.
While authorities are still trying to work out what triggered the accident, TMZ reports the sports car suffered a mechanical failure and a possible steering fluid leak.
The website writes that "sources connected to Always Evolving - the shop co-owned by Walker and the Porsche driver Roger Rodas [who also died] - tell TMZ they saw evidence of a fluid burst and subsequent fluid trail before the skid marks at the accident scene."
The sources also made evident the absence of skids leading up to where the crash took place, with marks only noticeable before the point of impact. They claim if Roger had lost control of the vehicle there would be visible signs on the road from swerving rather than in a straight line, suggesting he didn't have control of the steering.
TMZ continued to look into how the fire spread to the front of the car with such speed. Always Evolving insiders pointed out how bizarre it was the flames didn't start from where the engine was fitted in the car.
The car, which cost $500,000, was reportedly not modified as it was rarely driven - therefore sources believe the malfunction came from the factory.
Following Paul's death, stars have been in mourning at the loss of the Fast & Furious actor. His co-star in the action franchise, Vin Diesel, led the tributes, posting a photo of himself and Paul on his Instagram account.
"Brother I will miss you very much. I am absolutely speechless. Heaven has gained a new Angel. Rest in Peace (sic)," he captioned the picture.
