Kid Rock is "beyond devastated" after finding his personal assistant's body on his property. According to reports, 30-year-old Michael Sacha was killed in an apparent ATV accident early Monday (April 25).

Nashville's Tennessean newspaper reports that Sacha was ferrying guests who had attended a cookout at Kid Rock's estate in Whites Creek, Tenn. — a Nashville suburb — to an Uber at the driveway of the property around 12AM on Monday when he was last seen alive. Investigators say he apparently lost control of the vehicle and wrecked while returning to the house. Kid Rock (real name Robert Ritchie) and another friend found Sacha on an embankment late Monday morning and called for help.

Brian Haas, who works as a public information officer with the Nashville Fire Department, tells the Tennessean they responded to a call on Monday morning and found a man lying face down at the side of the property's driveway. He was dead when members of the fire department arrived.

Kid Rock expressed his sorrow at his young friend's tragic passing in a statement on his website.

"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," he says. "I know I speak for us all in sharing my deepest condolences to his family. I cannot imagine how they must feel. Myself, the band, our family, friends and co-workers are devastated over this loss."

The singer was scheduled to return to his home state of Michigan on Monday, "but I am going to stay here with Mike until I can bring him home to his family."

"We've already been contacted by the press asking if it was me who was in the accident, so I want to stop any rumors before they spread," Kid Rock adds. "I’m asking everyone to please respect our and his families' privacy in this difficult time. RIP Mike. We will never forget you, my friend."

Kid Rock is scheduled to headline at the Taste of Country Music Festival, WE Fest and Country on the River this summer, and will also join Jason Aldean at his sold-out show at Fenway Park in Boston in September.
