If I have knowledge that an Army Veteran was bilked out $ thousands & a Navy Officer was also a victim of theft by the same people what next?

The lawyer hired to settle the estate recommended I sign a compromise and allow the thieves to pay back $200, 000. I believe that the lawyer has the best interest of my godfather in mind, I signed. The other parities must come up with $200, 000 to settle their side of the agreement. A relative is selling the things she stole on eBay. Should I try to buy some of the items and help them raise the $200,000 so I can collect my inheritance? I never expected a penny so I was quite surprised at the amount left.
