He also made 13 criminal violations regarding union record keeping, between October 2009 and and June 2011, the U.S. Attorney's office said.Investigators found that Vincent made false entries on credit card receipts, passing them off as business expenses at Louisville restaurants, according to the news release.If convicted, Vincent faces up to 23 years in prison.An officer at Teamsters Local 783 was not immediately available for comment Tuesday afternoon.Local 783's website notes that the International Brotherhood of Teamsters put the local union under trusteeship in April 2012.
