The person killed when a bus carrying country star Josh Turner’s crew plunged 80 feet off a California embankment has been identified as the singer’s longtime sound engineer.

David Turner, 64, of Bruce, Miss. — who was unrelated to the singer — was killed when the bus suddenly veered off Highway 46 near Shandon late Wednesday, hurtling about 20 feet off the road before plunging down an embankment, Mississippi newspaper the Daily Journal confirmed, citing authorities and loved ones.

“It was with a heavy heart I learned that the one death reported in the California tour bus accident late last night, and on the national news today, was that of Oxford’s David Turner,” local folk historian John Cofield posted to Facebook, along with two photos of David — one with friends and one by himself, broadly smiling. “My thoughts and prayers are with his wife Jamie, daughter Ada and family. RIP David.”

Josh Turner and his band were on a different bus and not involved in the crash.

David Turner worked with sound, lighting and stage set-up on the singer’s tour crew, a family friend told the Journal.

David Turner was part of the singer’s crew for nearly 14 years — and previously worked for artists including Patty Loveless, Tammy Wynette, Bailie and the Boys and Eddie Rabbitt, according to TasteofCountry.com.

A total of seven other occupants of the bus were injured — two of them classified as major, fire officials said.

Drugs and alcohol have already been ruled out as a possible cause for the crash, with the California Highway Patrol looking to possible mechanical problems with the bus.

In the wake of the crash, the country star has postponed the rest of his September tour dates, Universal Music Group Nashville told the San Luis Obispo Tribune in a statement.

“Josh Turner and his road family have suffered a devastating loss,” the statement said. “Please keep the crew, band and Josh in your thoughts and prayers.”
