A San Antonio man was sentenced Friday to 18 months in federal prison after he was convicted of mail fraud.

According to the U.S. Department of Justice, Rodolfo Reyes Mata, also known as Rudy Mata, 40, submitted 15 fraudulent invoices to University Medical Center (UMC) in Lubbock from November 2010 through September 2011, knowing that the submission of such invoices would cause UMC to pay the invoices by mailing checks to addresses listed.

Mata and Robert Gregory Bruce, the former Vice President of UMC, caused UMC to pay approximately $54,750 to ATAM Technology Solutions for goods and services that were not provided. Mata then used these funds for personal living expenses, educational expenses, and travel and entertainment expenses.

Bruce was sentenced last month to 51 months in federal prison and ordered to pay $737,492 in restitution to UMC. 

Mata pleaded guilty to mail fraud and aiding and abetting in July of 2012. He was additionally ordered to pay the $54,750 back in restitution. He is scheduled to begin serving his prison sentence on November 22 of this year.
