CHARLESTON, W.Va. -- A former J.P. Morgan Chase Bank executive in Charleston was sentenced Wednesday to three years in federal prison for embezzlement. Mark Alan McCoy, 46, of Charleston, pleaded guilty in March to embezzling more than $500,000 from the bank. He was the vice president of private client banking services from September 2008 through June 2012, according to a news release from U.S. Attorney Booth Goodwin. Between November 2009 and April 2012, the release states, McCoy stole money from nine personal and corporate clients bank accounts. He created cashier's checks or would use the proceeds from the original cashier's checks to create additional unauthorized checks, the release states. In October 2011, McCoy created a cashier's check from a client's account for $22,000 and purchased a 1968 Chevrolet Camaro. In January 2011, he created a cashier's check from a client's corporate account for $59,000 and made the check payable to Moses automotive dealership. He then purchased a Cadillac Escalade, according to the release. U.S. District Judge Irene Berger ordered McCoy to pay back $447,784 - the amount the bank was not able to recover. The U.S. Secret Service conducted the investigation.
