For starters, the charges you're referencing appear to have been little more than an IRS witch hunt. Maybe he voted Republican?  

A joint investigation involving the IRS-CID and the United States Postal Inspection Service (USPIS), revealed that from at least 1990 through July 2006, SONNY VLEISIDES, James Ray Houston, Dennis Emmett, William Cloud, Henry Walther, Scott Henry Walther, and others committed a massive international lottery scam using the following company names: Shamrock Agency, German Swiss Group, World Expert Fund, Mutual Medical Insurance Co, Old Amsterdam Trust Co, Euro American Fax Co, European Union Commission, EU American Payment Co, Global Search Network, North American Foreign Payments Services, Wor'dwide Verification Service, and others. VLEISIDES ran the scheme along with Houston and Emmett. VLEISIDES, Houston and Emmett, who were all located in Costa Rica, worked with mailing houses which, at the direction of VLEISIDES, Houston, and Emmett, sent out tens of thousands of mailings to victims in the United States, many of whom were elderly. The mailings contained false statements, half truths, and omissions, and induced the victims to participate in various international lotteries, falsely stating that if the victims participated, they were guaranteed to win or had a very good chance to win. The mailings directed the victims to send their money to Ireland, at d the Netherlands, among other locations, where William Cloud had set up addresses with commercial mail receiving agencies and individuals to forward the money, eventually, back to the United States. After receipt at the commercial mail receiving agencies, the victims' money was sent to Henry Walther, who, along with his son Scott Henry Walther, deposited the money into various bank accounts and then distributed it as directed by VLEISIDES, Houston, and Emmett. Some of the money was spent on furthering the criminal activity. Some of the money was paid out to victims in small-dollar checks that the co-schemers misrepresented to be lottery winnings. The rest of the money was paid out to the co-schemers and others for their own use. VLEISIDES and the other defendants did not buy any lottery tickets, and the vast majority of the victims lost the money they sent. The total loss from the scheme is in excess of $19 million.

An analysis was done on approximately twenty of the bank accounts established in the United States at the direction of VLEISIDES and his co-schemers. The analysis revealed, in summary, that the victims' money was first deposited into accounts established by the co-schemers at numerous banks in accounts with names that sound like official lotteries: SHAMROCK AGENCY, WORLD EXPERT, OLD AMSTERDAM, GERMAN SWISS, and EUC. (Hereinafter, accounts at this first layer will be referred to as "Deposit Accounts.") The co-schemers obtained over $19 million from tens of thousands of victims and deposited them into these accounts. After the co-schemers deposited the victims' money into the Deposit Accounts, they transferred the money to the next layer of accounts, hereinafter referred to as "Payment Accounts." These accounts were in names that included NORTH AMERICAN PAYMENT and EU PAYMENT SERVICE. From the Payment Accounts, the co-schemers wrote checks represented as winnings and sent them back to the victims. The amount of the alleged "winnings" was far less than the amount the victims sent in - for the over $19 million going into the accounts from victims, only approximately 20% was sent back to victims in the form of "winning" checks. The co-schemers transferred some of the money from the Deposit Accounts and Payment Accounts to the next layer of accounts, which will hereinafter be referred to as "Syphon Accounts." The co-schemers wrote checks (or used wire transfers) from the Lottery Accounts and the Payment Accounts to the Syphon Accounts, which were in names that included WESTERN INTERNET, BUTTERFIELD, CARNEGIE and HENRY WALTHER ATTORNEY WIRE ACCOUNT. Money from the Syphon Accounts was used to continue the scheme by paying scheme expenses, as well as to provide benefits to the co-schemers. The co-schemers also took money at each layer in the form of checks to cash, checks to themselves, or checks to the payment of personal or scheme expenses.
