The United States Attorney’s Office (USAO) revealed details about the case in a press release on Monday. 31-year-old Mary Ann Magdamit, from Carson, pleaded guilty to one count of conspiracy to commit bank fraud. The former letter carrier for Torrance Main Post Office had reportedly stolen cards in the mail over a three-year period.
The press release claims that Magdamit committed the crimes from at least 2022 until she was arrested in July 2025. She reportedly stole mail containing checks and personal details alongside the cards. Magdamit then activated the cards online and purchased items with them. She also sold some of them to her accomplices.
The former postal worker allegedly told her co-conspirators to cash stolen checks using counterfeit IDs. “Federally insured banks and credit unions were victimized in this scheme,” The USAO explains.
Police Found An ‘Unserialized’ Gun At The Former Postal Worker’s Home
Authorities searched Magdamit’s home in December last year and found 133 stolen cards. They also found 6 U.S. Department of Treasury checks and an unserialized Glock-clone. The press release notes that the gun was loaded and had a 27-round extended magazine. The USAO explains that weapons without serial numbers are often called “ghost guns.”
Agents arrested Magdamit on July 1 after learning she continued to use stolen money. Officers made a second sweep of her property that day and found even more evidence. The press release reveals that the former postal worker showed off her luxury lifestyle on social media, including images of her expensive items and holidays. She also showed off stacks of $100 bills. The USAO reveals that Magdamit has “agreed to forfeit a Rolex watch and other luxury goods.”
Magdamit has a sentencing hearing on October 27 with United States District Judge John F. Walter. At that time, she will face a statutory maximum sentence of 30 years in prison.
