Former Torrance letter carrier pleads guilty to stealing checks, debit and credit cards from mail

A Carson woman, who is a former U.S. Postal Service employee, is facing decades in prison after pleading guilty to bank fraud.

Mary Ann Magdamit, 31, who worked as a letter carrier at the Torrance Main Post Office, stole checks, debit and credit cards from the mail from at least 2022 through July 2025, according to a press release from the United States Department of Justice.

Magdamit pleaded guilty Monday to one count of conspiracy to commit bank fraud. She's been in federal custody since July 1.

Federal prosecutors allege she would activate the stolen bank-issued cards online and use them to make purchases, and even sold some to her co-conspirators.

Magdamit is also accused of flaunting her loot on social media, even taking a photo with a thick stack of cash, before using it to pay for international trips and luxury goods.

After a search of her home in December of last year, authorities seized 133 stolen credit and debit cards, 16 U.S. Department of Treasury checks and a loaded "ghost gun."

Magdamit faces up to 30 years in federal prison.
