A former U.S. Postal Service carrier who worked in Southern California has been sentenced to five years and three months in federal prison for stealing and selling debit and credit cards and mailing checks.
Mary Ann Magdamit, 31, of Carson City, pleaded guilty on Aug. 11 to one count of conspiracy to commit bank fraud, which she committed while working at the Torrance Main Post Office from at least 2022 to July 2025, according to the U.S. Department of Justice.
Magdamit, who has been in federal custody since July 1, stole mail containing checks, personal information and debit and credit cards she had activated online and used for purchases, officials said. Investigators learned that Magdamit sold some of the stolen cards to her associates and used the money to travel internationally and purchase luxury goods.
According to the Justice Department, “She also arranged for co-conspirators to cash stolen checks, often with people’s forged identification using the name of the payee on the check.”
A search of Magdamit’s apartment in December 2024 uncovered 133 stolen credit and debit cards, 16 U.S. Treasury checks, and a loaded, unserialized Glock clone pistol with an extended 27-round magazine, often referred to as a “ghost gun.”

“She also used the stolen card on international travel to the Turks and Caicos Islands and Aruba,” the Justice Department said. In an Instagram post, Magdamit was seen showing off stacks of $100 bills.
Magdamit was arrested on July 1 after agents learned she continued to use the victim’s credit cards to make purchases, which were discovered during a second search of her apartment that day.
She was sentenced by U.S. District Judge John F. Walter and ordered to pay $660,200 in restitution. Magdamit is also required to forfeit a Rolex watch and other luxury goods, according to the Justice Department.
