The Los Angeles County coroner's office released its report on Friday detailing the car crash that actor Paul Walker and his friend Roger Rodas died in, as well as the outcome of the autopsies performed on the two men.

According to a report from People, the coroner's office confirmed that speed was the cause of the fatal crash that took place on Nov. 30, 2013 and took the lives of Walker, 40, and Rodas, 38.

Friends of the two had suspected mechanical failure as the cause because Rodas was a skilled race car driver, but that was evidently not the case.

"For unknown reasons, the driver lost control of his vehicle, and the vehicle partially turned around," the report says. The car, which was traveling at around 100 miles per hour at the time of impact, then struck a tree and a light post, spun 180 degrees, struck another tree and burst into flames.

"It appeared that the vehicle almost split in half," according to the report.

In terms of injuries, Walker sustained multiple fractures throughout his body, including his jaw, collarbone, left upper arm, ribs and pelvis.

The report states that Walker's body was found in a "pugilistic stance" as if bracing for an impact. It also notes that there was "scant soot" in Walker's trachea, suggesting that the Fast and Furious actor took a few breaths after the impact, TMZ reports.

Fox News describes Rodas's injuries as "gruesome," with the coroner's report stating that he was horribly burned and suffered a head trauma so severe that it exposed his brain.

The report says that both of the men's bodies were so badly burned that Rodas had to be identified through dental records, while Walker could not be "positively identified visually."

According to the Los Angeles Times, the limited-production, 2005 Porsche Carrera GT that was carrying Walker and Rodas has a history of being difficult to control.

"The sports car is capable of reaching 100 miles per hour in under seven seconds. It was built without the stability management system that most Porsche models are equipped with," the Los Angeles Times reported.
