An elderly woman was killed when the car she was driving hit a semi-truck head-on in Prescott Thursday afternoon. Prescott Fire crews were called to Iron Springs Road near the Alto Pit recreational area at around 4 p.m. When the first crews arrived, they started working on 81-year-old Nancy Fleming of Fort Worth, Texas immediately. The car was heavily damaged, while the semi-truck was off the road nearby. Another crew arrived and tried to remove parts of the car to get Flemming out. She suffered what fire officials are calling “multiple-systems trauma” and was pronounced dead at the scene. The truck driver suffered only minor injuries and refused treatment. Witnesses tell investigators the car hit a guardrail then veered into oncoming traffic, where it hit the truck.
