USPS Letter Carrier Pleads Guilty to Stealing
Mary Ann Magdamit, 31, a former U.S. Postal Service letter carrier from Carson, California, has pleaded guilty to federal charges related to a three-year scheme in which she stole checks, credit cards, and personal identifying information from the mail. She then used these stolen items to make unauthorized purchases, sell them to accomplices, and fund a lavish lifestyle, including international travel and luxury goods.
Details of the Scheme
Magdamit worked as a letter carrier at the Torrance Main Post Office. Between 2022 and 2025, she intercepted mail containing checks, debit and credit cards, and personal identifying information. She activated the stolen cards online, used them to make purchases, and sold some of the cards to co-conspirators. These accomplices used counterfeit identity documents to cash the stolen checks, defrauding federally insured banks and credit unions. In December 2024, law enforcement executed a search warrant at Magdamit’s residence and discovered 133 stolen credit and debit cards, 16 U.S. Department of Treasury checks, and a loaded, un-serialized Glock-style firearm, commonly referred to as a “ghost gun.” Investigators also found luxury items purchased with the stolen funds, including a Rolex watch and other high-end goods. Additionally, Magdamit used the stolen cards to finance international trips to Turks and Caicos and Aruba.
Social Media Revelations
Magdamit openly flaunted her illicit gains on social media platforms, posting images of luxury purchases, vacations, and stacks of cash. These posts drew public attention and contributed to the investigation into her activities.
Legal Proceedings and Sentencing
Magdamit was arrested on July 1, 2025, after continuing to use the stolen credit cards. She remains in federal custody and faces a sentencing hearing scheduled for October 27, 2025. The charge of conspiracy to commit bank fraud carries a maximum sentence of 30 years in federal prison. This case highlights the vulnerabilities within the postal system and the severe consequences of abusing positions of trust for personal gain.
