Hanson’s organization, ODOG operated in the United States, Central and South America, and Australia from 2012 to 2016. It sold a wide variety of drugs, including cocaine, heroin and methamphetamine in wholesale and retail quantities. It also ran a “vast illegal gambling network focused on high-stakes wagers placed on sporting events."
When he pleaded guilty, Fairfield admitted he aided ODOG by laundering money, creating a shell company to hide the group’s proceeds, and training ODOG money runners how to hide the enterprise’s activities from law enforcement and banks. Fairfield admitted ODOG used at least 26 bank accounts to launder more than $8.3 million in gambling proceeds from January 2011 to October 2015
He once used an alias and fake identification when he personally transferred proceeds from Hanson’s Australian drug trafficking to the U.S. The accountant also worked with the ringleader to track debt collection from bookies and gamblers who owed ODOG hundreds of thousands of dollars from illegal bookmaking.
Fairfield's firm, Fairfield Hughes CPAs, still bills itself as serving clients internationally. The firms website also notes "A major focus of our firm is providing service to military families and ex special forces working overseas on US Government contracts."
