A man driving one of Miley Cyrus’ tour buses was killed last night, after the bus drifted off the road and flipped over on I-85 south about 45 miles outside of Richmond, Virginia. According to officials, the roads were wet with rain last night, but the road conditions have not been singled out as the cause of the accident.

10 people were on board the bus at the time of the crash. The bus driver was killed and the other 9 people suffered minor injuries. Miley was on another bus in the 4-vehicle caravan, and was not involved in the accident.

Update: The 911 calls from the tour bus indicate that the bus driver, William Douglas, was suffering from a heart attack shortly before the bus drifted off the road.
