I was very impressed with the sincerity and genuine nature of the wife's plea in the newsclip I watched. This sounds like a good man, and it's just extremely suspicious that he vanished in to thin air just before a court hearing regarding his daughter. RED FLAG ANYONE?!? Was Tony getting custody of the daughter and was the mother of the child going to have to pay child support? That, of course, would make her a suspect in my books right there. If she hasn't been polygraphed, she should be. If the police aren't able to help, then go to the D.A.'s office. I believe the D.A.'s office will help you. They are generally wonderful people. If for whatever reason you still aren't getting the help you need, then you should persistently contact the Attorney Generals office.
In addition, a lawyer would help you navigate through all of this. If you can't afford an attorney (see if one will take it pro bono..."for free"). If not, contact the Dean of law at your local university and see if they will take this on as a class project. I would try and find a film student who will memorialize this and put it all over YouTube as well.
Finally, see if you can't find a local Private Investigator who wants to get some media visibility and have them take this on for free. And finally, finally, see if you can get a journalism student to write this all up and go pitch it to all the newspapers/media/etc.
Get busy, or find some sharp college seniors to help you out. Don't give up, I think you already know what happened....now you just need to prove that. MY OPINION ONLY.
God Bless You.
