IMO...contact the IRS. They're really good at auditing and figuring out where the money went. They might be able to bring the SEC back in (Eddie has already lied to them resulting in his ARTS being revoked). Maybe they'll want to make an example of him.
Also, I have a feeling Eddie could be a relatively low level player in these scams. Maybe they can figure out who his bosses are.
When he was arrested for felony theft a couple years ago Eddie told the magistrate he was a "Ukrainian citizen" (he was apparently born in the old Soviet Union). The Dallas magistrate was compelled by the Vienna Convention on Consular Relations to notify the Ukrainian Embassy in Washington DC saying "one of your citizens has been arrested on a criminal offense."
The Russian mafia is known to have its' hooks deep into US penny stock scams. Here's an example tied to one of Eddie's former partners Roxanna Green-Weber (EMXC, MPIX, HWAL). Dangerous business for sure
