A former Fairfield attorney who defrauded clients of more than $950,000 was sentenced in federal court Monday to three years in prison with three years of supervised release.

According to documents provided by the U.S. attorney for Connecticut, 53-year-old John O'Brien admitted to defrauding clients between April 2011 and June 2014 by using funds from one client to pay off debts owed to others. In one instance, O'Brien used $31,000 in client funds to pay his son's tuition to a private high school, according to court documents.

O'Brien, who resigned from the Connecticut bar in June 2015, pleaded guilty to one count of wire fraud in December.
