WILLIAMS – Coconino County Sheriff’s deputies and detectives are investigating a one vehicle roll over collision that occurred on Monday, July 21, 2014 at about 5:25 pm on Drake road in close proximity to the Bar Heart Ranch headquarters. There were two vehicle occupants; the driver and a front seat passenger.

At this point in the investigation deputies believe the vehicle was traveling at a high rate of speed as it crested the hill just to the east of the Bar Heart Ranch. It is believed the driver began to lose control as the vehicle reached the bottom of the hill and slid across both lanes of traffic. The vehicle hit a large rock on the shoulder of the road and eventually rolled over once completely and then flipped end over end one time completely. Deputies believe 32-year old Rocky Deibler of Williams was ejected at the beginning of the roll and came to rest approximately 20 feet from where he left the vehicle resulting in severe head trauma.

Mr. Deibler was flown to the Flagstaff Medical Center by Native Air medical transport where he was subsequently pronounced deceased. The second vehicle occupant was taken to the Yavapai Regional Medical Center by Lifeline Medical transport where he was treated for non-life-threatening injuries.

Deputies are investigating the possibility that impairment from the consumption of alcohol or other substances may have played a role in this collision. Investigators are attempting to determine which of the two occupants was driving at the time of the collision. No enforcement action has been take at this time.

The deceased victim was taken to the office of the Coconino County Medical Examiner for further examination and investigation.

Arizona Department of Public Safety Officers assisted with this investigation. Additional agencies that responded and assisted with patient care, the collision investigation, or scene management include the Yavapai County Sheriff’s Office, Chino Fire Department, and the Ash Fork Fire Department.
