My husband serves as an expert witness conducting forensic accounting services and reporting findings on cases involving real estate and financial services and I would LOVE to help him were his firm were to be hired to dig into the financial matters of FORE Group as I'm sure it would be fascinating exploration. I also have a professional accounting and auditing background although I've been long retired, so I often serve as a sounding board for him in the work he does and I love the chase of figuring things out and discovering the ends to which some people will go.
IMO, it at least appears there was plenty of intermingling of personal and business expenses and assets. There also appear to be examples of providing rent-free housing and other services or assets to friends or relatives. It also appears there may have been below-market related-party financings (some of which may have been undocumented) and I wonder if those loans were disclosed to banks when applying for additional financing and/or to insurance underwriters when applying for construction bonds. So, IMO possible fraud on financing applications and underpaid taxes at the very least. (FD claims that JFD's late advances were a gift, but how many of us here assume that he reported that gift?) Given the fraud involved in the bail bonding process at the end, I wouldn't be a bit surprised to discover that construction bonds might also have had issues. Given that FD was Greek, both he and MT maintained strong international relationships with friends, family, and other associates, and traveled internationally with some frequency - and in light of likely dishonest reporting domestically - I wouldn't be a bit surprised to find more there.
However, unless the state seriously entertains a challenge to FD's estate on the part of FD's Greek relatives, to what end would a forensic accounting investigation be worth the cost and effort? FD is gone and the company is no longer operating. MT and KW are already charged with significant crimes. Chasing down the international movement of money or other assets in particular would likely be very difficult, although if I were custodian of those properties currently believed to be in the estate I would definitely want to research current status of title and pronto.
