At some point, I envision the dad stepping in and doing everything possible to make this right and protect his family from any future scorn. That's the only hope left, I believe, in recovering any funds.
If that's your only hope, you're fucked. Mom and Dad still have an active Chapter 13 bankruptcy case open, started in 2008, 08-41485 (ED TX), in Feb 2011 the trustee filed a motion to dismiss their bankruptcy because they were not current on their court-ordered payment plan. That was corrected, and it looks like they'll be making payments through July 2013.
Drop me a PM if you want copies of documents, they're public records.
