Authorities in California will continue an investigation into a reported golf cart incident involving Denver Broncos icon John Elway. They confirm that all witnesses have been interviewed and there is currently no evidence suggesting any wrongdoing.

According to TMZ, the event occurred on April 26 at The Madison Club in La Quinta, California, with John Elway at the wheel of a golf cart when Jeffrey Sperbeck, his long-time agent and companion, aged 62, fell out and injured his head.

The two were leaving a Stagecoach after-party, the outlet reported.

A representative from Cal Fire informed Fox News Digital that Sperbeck suffered “serious injuries” and was taken to a hospital. Initially listed in critical condition, he passed away on April 30.

In a statement released after Sperbeck’s death, Elway said he was “devastated,” according to ESPN.

“I am absolutely devastated and heartbroken by the passing of my close friend, business partner and agent Jeff Sperbeck,” Elway said. “There are no words to truly express the profound sadness I feel with the sudden loss of someone who has meant so much to me.”

Sperbeck’s family also released a statement.

“We are deeply saddened to share the passing of our beloved Jeff Sperbeck. He was a wonderful father, husband, brother, son and friend to many and will be profoundly missed by all,” the Sperbeck family said. “We are grieving this unimaginable loss as a family alongside our dearest friends the Elway’s and the many other clients Jeff called friends.”
