BURLINGTON — A Connecticut man, who is charged with defrauding the office of the Vermont State Treasurer out of nearly $475,000, had his federal court hearing postponed on Thursday when he tested positive for drugs. Cirt F. Lindsay, 43, of Bridgeport, Connecticut, was due to plead guilty in U.S. District Court to conspiracy to commit mail fraud by stealing the money from the Unclaimed Property Division for the Vermont State Treasurer’s Office, federal court records show.
