Law enforcement sources tell us ... they want a full analysis of the Carrera GT, including brakes, engine and body. They also want the experts to help determine speed at the time of impact. Our sources say they're also interested in the tires, and at least one is available for analysis because it was not completely destroyed in the fire.
