Sperbeck, who was Elway’s agent, suffered the fatal fall last Saturday at the Madison Club, a private country club in California. Immediately following the accident, Elway’s party called 911.

Investigators told the Denver Post “nothing” they have discovered leads them to believe the head injury Sperbeck suffered is a law enforcement issue.

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