Authorities investigating the death of John Elway's longtime friend and agent Jeff Sperbeck have not found any criminal activity involved in the accident, the Riverside County (Calif.) sheriff's department said Friday.
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.
