Several months sooner than expected, a Berrien County businessman is now in prison Thursday morning.

John Bertuca of St. Joseph is at a minimum security prison in Oxford, Wisconsin.

Bertuca owned several businesses, including Bertuca Bonding and Insurance.

 Bertuca is serving time for filing false tax returns and agreed to testify in a $52 million ponzi scheme trial set for April.

He was scheduled to serve his sentence after that trial.

Because of the government shutdown, we are unable to find out why he started serving his sentence now.
