Three Miami-Dade Residents Sentenced For Fraud Scheme

Wifredo A. Ferrer, United States Attorney for the Southern District of Florida, and Paula Reid, Special Agent in Charge, United States Secret Service (USSS), Miami Field Office, announce today’s sentencing of defendants Mario R. Triana Martinez, 24, of Miami, Emilio Mederos, 24, of Miami, and Francisco Cartaya, 25, of Hialeah, for charges relating to their participation in a scheme to defraud T-Mobile and Wal-Mart by fraudulently obtaining cellular telephones through the unauthorized use of account information of valid T-Mobile customers.

At today’s hearing, U.S. District Judge Donald L. Graham sentenced Mario R. Triana Martinez to 41 months in prison, to be followed by three years of supervised release. Emilio Mederos was sentenced to 33 months in prison, to be followed by three years supervised release. Francisco Cartaya was sentenced to six months in prison, to be followed by one year of supervised release. Triana Martinez, Mederos and Cartaya were also ordered to pay restitution in the amount of $232,803.88. All of the defendants pled guilty on October 8, 2013 to conspiracy to commit wire fraud.

According to court documents, between May 2010 and July 31, 2011, Triana Martinez, Mederos, Cartaya, co-defendant Yandy Rosell Trujillo and others, participated in a scheme to defraud T-Mobile and Wal-Mart by fraudulently obtaining cellular telephones using the personal identification information, such as account numbers and social security numbers, of valid T-Mobile customers, and then re-selling the cellular telephones at a profit. As part of the fraud, Triana Martinez and Mederos, who had unauthorized access to valid T-Mobile customer account information, called T-Mobile, and impersonating a T-Mobile dealer over the telephone, caused the name on a valid T-Mobile account to be changed to match the name of one of the co-conspirators. Once the name on the T-Mobile account was changed, Triana Martinez, Mederos, Cartaya and Rosell Trujillo visited Wal-Mart locations in eleven different states, including locations in the Southern District of Florida; provided the account number or social security number of the valid T-Mobile customer; and proceeded to purchase cellular telephones, such as BlackBerrys or HTCs, at a deeply discounted rate reserved for qualified T-Mobile customers. Triana Martinez and Mederos thereafter sold the fraudulently-obtained cellular telephones at a profit. This fraudulent scheme resulted in losses to T-Mobile and Wal-Mart in excess of $200,000.00.

Defendant Yandy Rosell Trujillo, 28, of Hialeah, pled guilty to conspiracy to commit wire fraud on October 16, 2013, and is scheduled to be sentenced on January 9, 2014.

Mr. Ferrer commended the investigative efforts of the Secret Service. The case was prosecuted by Assistant U.S. Attorney Elisa Castrolugo.
