The vehicle rolled and killed the occupant because the roof caved in. The shoulder portion of the seat belt did not hold the occupant (only the lap portion) and the occupant was partially ejected out of the rear of the cab. The vehicle was inspected and purchased by State Farm insurance since the vehicle was totaled. The 2000's Ford F-150s have roofs that are too weak to support the weight of the vehicle, thereby putting the occupants in danger of injury or death. This is well documented. There were no warnings.
