The U.S. District Court in Portland, Maine sentenced a 62-year-old man to prison for running a multimillion-dollar gambling operation.

According to the Portland Press Herald, Stephen Mardigan had run the operation from 2003 until April 2017, when federal investigators confiscated $850,000 in cash and jewelry from him and three others.

Last May, he plead guilty to the charges of running the gambling business, money laundering, and misdeclaring information in his used car company’s income tax return.

Mardigan had supposedly faced 20 years in prison for the money laundering charge alone, but Chief Judge Jon Levy said that federal guidelines and mitigating factors reduced this considerably. The federal prosecutor wanted Mardigan to serve 21 months, while the defense requested merely probation.
