Former USPS Worker Busted for Stealing Credit Cards from the Mail, Living Luxury Lifestyle

A former United States Postal Service (USPS) worker pleaded guilty for stealing from customers on her Los Angeles-area mail route, in a three-year scheme.

The suspect, Mary Ann Magdamit, allegedly stole credit and debit cards and checks from the mail, and used the funds to travel overseas and buy luxury goods. She also boasted of the luxury lifestyle on Instagram posting pictures of travel, cash, and goods. 

The 31-year-old Magdamit, who worked in the post office in Torrance, California, pleaded guilty to one count of conspiracy to commit bank fraud. She was arrested on July 1, not long after she posted images of the stolen cash on Instagram while working at the Torrance Main Post Office.

According to prosecutors, the scheme ran from at least 2022 until July 2025. The suspect stole the cards, activated them, bought items with them, and sometimes sold stolen cards to co-conspirators. The suspect also arranged to have co-conspirators cash stolen checks, usually using counterfeit identity documents in the name of the check’s payee. 

When law enforcement searched Magdamit’s apartment in December 2024, they found 133 stolen credit and debit cards, 16 U.S. Department of Treasury checks, a “ghost gun,” and a trove of luxury goods. She also took trips to the Turks and Caicos and Aruba. 

Magdamit was fired by USPS after the December 2024 search. 

As part of her plea deal, Magdamit agreed to forfeit some of those luxury goods including a Rolex watch. Sentencing is on October 27, and she faces a maximum of 30 years behind bars. 

The U.S. Postal Service Office of Inspector General, the U.S. Postal Inspection Service, and the Treasury Inspector General of Tax Administration investigated the case.
