Charlie and Braden Powell were attacked and killed by their father Josh Powell while he was under suspicion for their mother Susan Powell's disappearance. Police say when the two boys were brought to Powell's Pierce County home by a state caseworker for a supervised visit in February 2012, Powell locked out the caseworker, killed the boys with a hatchet and then killed himself in an explosive fire that destroyed the home. The wrongful death lawsuit was originally brought in 2012 by Susan Powell's parents, Judy and Chuck Cox of Puyallup, who allege that negligence by the state Department of Social and Health Services was a contributing factor that led to the deaths of their grandsons at the hands of their father.. The lawsuit was thrown out in 2015 but was revived earlier last year by the 9th Circuit Court of Appeals.
