Miley Cyrus Bus Driver Died of Cardiac Arrest

More information has been released regarding the accident involving Miley Cyrus’ tour bus. As Hollyscoop reported earlier, the driver of the bus, 53-year-old William Douglas, was killed in the crash. And now TMZ has gotten a hold of the 911 tape.

In the first call, the caller tells the dispatcher the bus driver is still alive, but "losing color."

Officials are currently investigating whether or not the driver died before the crash occurred ... which would help explain how the bus drifted off the road and then crashed.

In the second call, which sounds like it's being made by a different person, the caller says the driver was suffering cardiac arrest.

Police say there were no obvious signs that alcohol played a factor in the crash, and believe Douglas may have had health-related issues. The matter is still under investigation.

Miley herself has issued a statement regarding Douglas’ death. She wrote on her website, "We are deeply saddened by the loss of Bill 'Uncle Bill' Douglas. Members of our tour are like members of our family. Our thoughts and prayers go out to his family in the midst of this tragedy. He will truly be missed."
