I recall going thru this when these guys were arrested and we couldn't find that for them. There was a lot of that in our area a few years back, companies set up on paper and registered w/Sec.State, but not an actual business. They appeared as Entities in fraud cases, but the connections went too high for anything to be done by the IRS or FBI.
But for getting exposed there were a whole maggots nest of players who lost their positions.
