Side/window Air Bag problems of the 2008 Ford F-250

My daughter and her fiance were involved in a wreck. His 2008 Ford F-250 super duty truck flipped end over end. They were very badly injured. The driver air bag nor the passenger side air bag deployed. His neck was broken by the steering wheel or dash and she received injuries to her face and had to get stitches, along with other injuries. We saw a Ford f-150 a few days later with damage to the front end and passenger side and the air bags deployed. I want to know if this is a defect in his pickup and what can we do.
