A Benton man pled guilty Wednesday in federal court to defrauding his former employer, Southern Illinois Healthcare.

Court records show that a federal grand jury in January returned an indictment on 48-year-old Cary E. Mosley charging him with wire fraud and mail fraud.

From Dec. 1, 2006 through July 13, 2013, Mosley was the manager of SIH’s radiation oncology department and held a second job with Q.E.D. Medical Physics, Inc., a contractor based in Lebanon, Tennessee, that provides support services for radiation oncology departments operated by small hospitals.

As part of his guilty plea, Mosley admitted that Q.E.D. paid him for work he allegedly performed at SIH and that he made entries in Q.E.D.’s electronic timekeeping system which falsely claimed he had performed work at SIH that he had not actually performed. He admitted to claiming compensation from Q.E.D. for work he performed as part of his normal employment duties with SIH that were falsely inflated. The indictment alleges that Mosley was paid over $500,000 by Q.E.D. for work he performed at SIH.

Mosley hid his fraud scheme by altering documents that were sent to SIH’s accounts payable department in support of the Q.E.D. invoices. Each month, Q.E.D. sent to SIH and “Hours and Details” sheet, which identified the Q.E.D. employees who had worked at SIH, the work they had performed, the number of hours they had worked and the dates they had worked.

During the initial portion of his scheme, Mosley altered the “Hours and Details” sheets by removing his name and inserting the names of other Q.E.D. employees. During the latter portion of his scheme, Mosley simply discarded the “Hours and Details” sheets before the Q.E.D. invoices were sent to SIH’s accounts payable department.

Mosley pled guilty to one count of wire fraud and one count of mail fraud. Both charges carry maximum sentences of up to 20 years in prison, up to three years of supervised release and fines of up to $250,000. In addition, Mosley could be ordered to pay full restitution to SIH.

Mosley’s sentencing is currently scheduled for Sept. 25 at 9:30 a.m. at the federal courthouse in Benton.
