The sports car in which Paul Walker died, crashed as a result of mechanical failure. It was said that it is very possibly a steering fluid leak, according to sources closely tied to the auto shop where the vehicle was stored and maintained. Sources connected to Always Evolving — the shop co-owned by Walker and the Porsche driver Roger Rodas, tell TMZ they saw evidence of a fluid burst and subsequent fluid trail before the skid marks at the accident scene. The AE sources claim there is an absence of skid marks until just before the point of impact. They say if Roger had lost control the skid marks would show swerving, but instead the marks were in a straight line. They feel this cements the theory the driver didn’t have steering control. Another thing that was so suspect is that the fire spreading so quickly in the front of the car. The sources say flames would be expected in the rear where the engine is … but fire in the front reinforces their theory of a fluid leak of some sort. TMZ claims the $500,000 Carrera GT was NOT modified and was driven rarely so they believe any failure must be a factory defect. As one source said, “Roger was a world class driver” — and while he might have been speeding, as cops have said, the notion he just lost control just can’t be it.
