Carson Woman and Former U.S. Postal Service Employee Pleads Guilty to Stealing Checks and Credit Cards from the Mail

United States Attorney's Office Central District of California

LOS ANGELES – A South Bay woman who formerly worked as a letter carrier for the United States Postal Service in Torrance pleaded guilty today to stealing checks and debit and credit cards from the mail then selling them to her accomplices for three years, using the illicitly obtained funds to take international trips and buy luxury goods, and then flaunting the cash on Instagram.

Mary Ann Magdamit, 31, of Carson, pleaded guilty to one count of conspiracy to commit bank fraud. 

Magdamit, who has been in federal custody since July 1, is a former letter carrier at the Torrance Main Post Office.

According to her plea agreement and court documents previously filed in this case, from at least 2022 until July 2025, Magdamit stole mail containing checks, personal identifying information (PII), and debit and credit cards. She then activated the stolen bank-issued cards online, used the cards to make purchases, and sold some stolen cards to her co-conspirators.

She also arranged to have her co-conspirators cash the stolen checks, usually by people using counterfeit identity documents in the name of the check’s payee. Federally insured banks and credit unions were victimized in this scheme.

Law enforcement searched Magdamit’s apartment in December 2024, and seized 133 stolen credit and debit cards,16 U.S. Department of Treasury checks, and a loaded, un-serialized Glock-clone, with an extended 27-round magazine, commonly referred to as a “ghost gun.” Agents also discovered luxury goods purchased with cards she stole from the mail. She also used stolen cards on international trips she took to Turks and Caicos and Aruba.
