An 83-year-old Golden man was behind the wheel when his Saturn SUV crossed a double yellow line on Colorado 93 and crashed head-on into a Jefferson County sheriff’s motorcycle deputy, according to the State Patrol.

The deputy, whom the sheriff’s office has not identified, died in the accident Sunday, said Trooper Josh Lewis.

The accident happened shortly after 10 a.m. near West 64th Parkway, Lewis said.

The deputy was entering a sweeping curve on his Harley-Davidson patrol motorcycle when the Saturn Vue tried to pass a southbound vehicle and hit the bike in the northbound lane.

“The deputy was thrown from the Harley-Davidson. Although he was wearing his helmet and eye protection, he sustained fatal injuries and was pronounced dead at the scene,” a news release said.

Kenneth Hosch, 83, the SUV driver, was transported to St. Anthony Central Hospital with minor injuries, Lewis said.

Neither drugs nor alcohol appear to have been involved, Lewis said. “Charges are pending.”

“Identification of our deputy will not be made until tomorrow, as we are still in notification stage,” Sheriff’s spokesman Mark Techmeyer said.

The Arvada Police Department, Lakewood Police Department, and Jefferson County district attorney are assisting with the investigation.

The roadway remains closed with no estimated reopening time.
