In addition, I would call the FSD at PHX, demand the tape be pulled, and let him know you have sent him and the OIG an e-mail to that effect.
THIS!
You are going to get all sorts of suggestions, but this one - please, please, please call and email right now and make your request for the video.
I am so, so sorry for what TSA/DHS has inflicted on your family, and a theft to top it all off. I sincerely hope you can obtain the tapes.
