The crimes happened between 2009 and 2018.

DiPietro was a certified public accountant (CPA) when he and Karasarides operated the gambling businesses together.

They earned at least $7 million in profits, the DOJ stated.

Both men tried to hide their ownership by using nominee owners and “sham contracts,” prosecutors said.

Karasaides caused a tax loss to the IRS of $5.4 million while DiPietro created a tax loss of over $4 million to the IRS.
