A tour bus carrying lighting crew members of Miley Cyrus’ tour overturned this morning, killing the driver.

The bus - one of four traveling near Richmond, Virginia - for some reason went off the side of I-85 before hitting an embankment and falling on its side. The victim, who was pronounced dead on the scene, has not yet been identified. Of the 14 passengers on-board (including the driver), 9 others reportedly sustained relatively minor injuries.

The circumstances of the 8:15 a.m. accident are still being investigated. It’s not known whether rain may have played a role.

The 16-year-old singer, who is set for a Sunday concert in Greenboro, N.C., was not traveling with any part of that caravan. At this time, she is still scheduled to perform this weekend.
