A San Antonio man has pleaded guilty to mail fraud in a case related to the conviction of a former University Medical Center vice president.

Rodolfo Reyes Mata, also known as Rudy Mata, pleaded guilty to one count of mail fraud and aiding and abetting.

Mata submitted 15 fraudulent invoices to UMC for ATAM Technology Solutions, causing the hospital to pay nearly $55,000 to the fraudulent company.

Former UMC Vice President Greg Bruce pleaded guilty in June to a similar offense.

Bruce admitted that he conspired with Mata to submit fraudulent invoices for ATAM Technology Solutions and B.R. Media Monitoring, a fake company devised by Bruce, causing UMC to pay nearly $682,000 on invoices to these fraudulent companies.

The fraudulent activity ran from June 2007 through December 12, 2011.

The funds were used, in part, to pay Mata’s personal living expenses, educational expenses, and travel and entertainment expenses.

Overall, UMC identified approximately $735,000 that was embezzled.

Both Mata and Bruce face up to 20 years in federal prison, a $250,000 fine, and restitution.
