California authorities say the death of Jeff Sperbeck in a golf cart accident appears to be a horrific accident.

Sperbeck died on Wednesday after sustaining a traumatic head injury from falling out of a golf cart that Elway was driving at The Madison Club in La Quinta, Calif., during the Stagecoach music festival. He was taken to a local hospital and put on life support and ultimately died from his injuries.

Reality TV star Johnny Bananas was on the golf cart with John Elway and Jeff Sperbeck at the time of the incident, according to TMZ. Bananas, whose real name is Johnny Devenanzio, was standing on the back of the golf cart with Sperbeck, TMZ reports. John Elway and his wife were in the front seat.
