Transcript for Susan Powell's parents awarded $32 million for death of grandsons: Part 11
All please rise. Please be seated. Court is reconvened. Has the jury reached a verdict, ma'am? It pleases the court, we have. Was the state of Washington negligent? Answer, yes. What do you find plaintiff Charles Powell's total amount of damages? $57,500,000. Braden Powell's total amount of damages? $57,500,000. For eight years, the cox family has been trying to find justice, and it took us a long time, and we took a long hiatus with the pandemic. Today justice has been meted out. What I intend to do is use the award to try and help other people in th so that we can save more children. Jury members told ABC news they didn't believe any one individual at child protective services was responsible for what happened. They blame a systematic failure for the tragedy. It just came down to this -- you cannot have reunification, you know, as your goal at the expense of child safety. And, you know, lawsuits change things, brown vs. Board of education, roe V. Wade. I mean, that's how things change. So "20/20" reached out to several agencies in both states, and they declined to comment, or referred us to other departments. In the end, we were unable to get an answer to our questions. Could the actions of these agencies, or their inactions, have contributed to the murders of Braden and Charlie Powell? It should've never have got to the point where you had Josh getting his kids into that house and blowing it up. I think that it is just one of those cases that we'll always kind of have a place in Utah's consciousness. And I think a big part of that is we still don't know what happened. We still don't know where Susan Powell is. Does everyone believe that he harmed his wife? The answer is yes, that's what everyone believes, but what you believe and what you can prove are two different things. Josh's actions are definitely an admission of guilt. She's going to divorce him if he can't have her, nobody will. So he kidnaps Susan, and most likely murders her and disposes of her body. Where? Nobody knows. The last that she was seen and heard from was her friend yavonna was there at the house. And Josh, who never cooked, made pancakes for dinner. People think he poisoned her, of course, because he made them separate, she felt sick and sleepy. Yavonna saw that, and then she's never heard from again. I know there are 10,000 abandoned mines in Utah. That's a lot of places where you can dump a body. There are so many theories, I don't know which one it is, but I guarantee you, Susan cox Powell did not leave that home willingly at midnight to go camping. This was a family that was not known to the West Valley City, Utah, police department. They had never been called to the house. But in other ways, Josh was just a classic abuser. He was controlling. My heart absolutely breaks for chuck and Judy cox. I mean, think about what this couple has gone through. They lost their daughter. Both of their grand babies were hohorrifically butched, and the only three people that could shed any light on this are dead. Her story will continue to on and inspire others to move in the right direction, to move towards good relationships and get out of bad situations, abusive situations.
