California authorities have concluded the investigation into the fatal golf cart incident that resulted in the death of Jeff Sperbeck -- the longtime friend, business partner and former agent of Denver Broncos Hall of Fame quarterback John Elway.

Riverside County Sheriff Chad Bianco confirmed that nothing criminal was found in an investigation into the incident that led to the death of Jeff Sperbeck.

John Elway will not be charged in the April incident in which his longtime business partner fell off a golf cart driven by the Hall of Fame quarterback and later died, a Denver television station reported.
