A former Torrance USPS letter carrier admitted to stealing checks and cards from the mail, using the funds for luxury travel and purchases she flaunted on Instagram. She faces up to 30 years in prison.
LOS ANGELES — A South Bay woman who formerly worked as a letter carrier for the United States Postal Service (USPS) in Torrance has pleaded guilty to stealing checks and debit and credit cards from the mail over a three-year period, then selling them to accomplices, using the illicit proceeds for luxury travel and purchases, and flaunting the cash on Instagram.
Mary Ann Magdamit, 31, of Carson, entered her plea on Monday, August 11, to one count of conspiracy to commit bank fraud. She has been in federal custody since July 1 and previously worked at the Torrance Main Post Office.
Details of the scheme
According to her plea agreement and court documents, from at least 2022 until July 2025, Magdamit stole mail containing checks, personal identifying information (PII), and debit and credit cards. She activated stolen bank-issued cards online, used them for personal purchases, and sold some cards to her co-conspirators.
Prosecutors said Magdamit also arranged for her associates to cash stolen checks, typically using counterfeit identity documents in the name of the payee. The scheme caused losses to federally insured banks and credit unions.
Search and seizure
In December 2024, federal agents searched Magdamit’s apartment and seized 133 stolen credit and debit cards, 16 U.S. Department of the Treasury checks, and a loaded, unserialized Glock-clone with a 27-round extended magazine — commonly referred to as a “ghost gun.” Investigators also found luxury goods purchased with stolen cards.
Authorities said Magdamit used stolen funds to take international trips, including to Turks and Caicos and Aruba. She documented the lavish spending on Instagram, posting images of luxury purchases, vacations, and stacks of hundred-dollar bills.
Agents arrested Magdamit on July 1 after discovering she continued to make purchases using victims’ credit cards. A second search of her apartment that day uncovered additional stolen cards. She has agreed to forfeit a Rolex watch and other luxury items.
Sentencing and prosecution
United States District Judge John F. Walter has scheduled Magdamit’s sentencing for October 27. She faces a statutory maximum sentence of 30 years in federal prison.
The case was investigated by the U.S. Postal Service Office of Inspector General, the U.S. Postal Inspection Service, and the Treasury Inspector General for Tax Administration. Assistant United States Attorney Andrew Brown of the Major Frauds Section is prosecuting.
