LOS ANGELES – A former U.S. Postal Service letter carrier in Torrance, Mary Ann Magdamit, 31, of Carson, has pleaded guilty to one count of conspiracy to commit bank fraud after a years-long scheme that involved stealing checks and credit cards from the mail.
According to court documents, Magdamit stole mail containing checks, personal identifying information (PII), and debit and credit cards. She then activated the stolen bank-issued cards online, made purchases, and sold some stolen cards to her co-conspirators.
The scheme, which ran from at least 2022 until July 2025, targeted federally insured banks and credit unions. Magdamit arranged for her accomplices to cash the stolen checks using counterfeit identity documents, court records show.
Law enforcement conducted a search of Magdamit’s apartment in December 2024, where they seized 133 stolen credit and debit cards, 16 U.S. Department of Treasury checks, a loaded, un-serialized Glock-clone, and luxury goods purchased with the stolen funds. International trips to Turks and Caicos and Aruba were also discovered.
Magdamit was arrested on July 1 after authorities learned she continued to make purchases with victims’ credit cards. She remains in federal custody and faces a maximum sentence of 30 years in prison at her October 27 sentencing hearing.
The U.S. Postal Service Office of Inspector General, the U.S. Postal Inspection Service, and the Treasury Inspector General of Tax Administration investigated the case. Assistant United States Attorney Andrew Brown is prosecuting it.
