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 Mr. Deibler 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.
