Two passengers have died after a truck rolled down a Butte County canyon, but two Chico men survived that crash Wednesday afternoon on Concow Road. The CHP says all four people in the truck were not wearing seat belts and were ejected. 19 year old Charles Taylor and Samuel Montgomery were able to hike to the top of the canyon and flag down help. They were flown to Enloe Hospital with moderate to major injuries. The CHP has identified the two passengers killed in the crash as 24 year old Tyler Matlock and 39 year old Kara Hanson. Officers say the cause of the accident appears to be distracted driving.
