First, I am not a lawyer.
I wonder if racketeering fits the bill --

The element of 'racketeering activity' is extremely broad. The statute includes kidnapping, gambling, arson, robbery, bribery, extortion, or a list of many other criminal statutes. The more common statutes include fraud, obstruction of law enforcement, forgery, and trafficking statutes.

At the very least (if convicted) these guys committed fraud. Servis made and probably already banked over $1 million for his trainer's share of the Saudi race alone.

Not sure if they were indicted for racketeering but it seems a solid fit. Conspiracy as well. Both felonies.
