Kid Rock's assistant was killed in an ATV accident overnight at a suburban Nashville property belonging to the singer.
The Tennessean reports 30-year-old Michael Sacha was found lying face down on the side of a driveway of Rock's White Creek house early Monday morning.
Nashville Fire Department spokesman Brian Haas told The Tennessean that Sacha was deceased by the time the department arrived.
"He was a member of our family and one of the greatest young men I have ever had the pleasure to not only work with, but also to become friends with," Rock wrote in a message posted to his website. "I know I speak for us all in sharing my deepest condolences to his family. I can not imagine how they must feel. Myself, the band, our family, friends and co-workers are devastated over this loss."
A news release from the Metro Nashville Police Department says the accident happened when Sacha drove two people down the driveway to meet an Uber driver at midnight.
Sacha crashed while riding the ATV back to the residence. Rock, whose real name is Robert Ritchie, and a friend found Sacha on an embankment late Monday morning and called for help.
The police department tweeted Monday evening that Sacha's death has been classified as accidental.
