A 26-year-old Pennsylvania man was sentenced Wednesday to just over three years in federal prison after he pleaded guilty to cashing more than $2.2 million in fraudulent U.S. Treasury checks.

Albelk Reyes Serrata, also known as “Alberto Reyes,” of Philadelphia, pleaded guilty May 28 to conspiring to steal fraudulent checks from the U.S. Treasury between 2012 and 2013, U.S. Attorney Walk Green said Wednesday in a news release. He obtained more than 350 checks and had them cashed by another person.

In addition to prison time, Serrata was ordered to pay $2.2 million in restitution and to forfeit $220,000 as proceeds from his criminal conduct.

Serrata’s case is part of a broader investigation of Baton Rouge check-cashing businesses that are believed to have cashed millions of dollars from fraudulent U.S. Treasury checks, the release says.

Anyelina Reyes, 36, of Baton Rouge, who is awaiting her sentence, pleaded guilty to using her Florida Boulevard business, “A&R Elite Team,” to help Serrata by cashing about 370 checks he sent her using her business account. Reyes pled guilty Nov. 20.

Carlos L. Linares, 55, of Baton Rouge, is accused of cashing more than 250 U.S. Treasury checks through his business, “Latinos Supermarket,” also on Florida Boulevard, but he has pleaded not guilty.

The Internal Revenue Service continues to investigate this matter.
