A man who went from teenage millionaire to convicted con artist to professional fraud fighter and pastor was convicted Wednesday of cheating his San Diego church congregation out of some $3 million.

Barry Minkow pleaded guilty to embezzling funds from the San Diego Community Bible Church, a U.S. attorney’s statement said. He was already serving a five-year sentence for a securities fraud conviction in Florida and could get five additional years when he is sentenced for the new conviction April 7.
