LOS ANGELES
A former Torrance letter carrier pleaded guilty to stealing checks and bank cards from the mail for three years, then using and selling them to fund luxury shopping sprees and international trips, officials announced Monday.
Mary Ann Magdamit, 31, of Carson, admitted to conspiracy to commit bank fraud.
Between 2022 and July 2025, officials stated that she stole mail containing checks, personal information, and debit and credit card details. She activated stolen cards for purchases, sold others to accomplices, and arranged for stolen checks to be cashed with fake IDs. Victims included federally insured banks and credit unions.
A December 2024 search of her apartment yielded 133 stolen credit cards, 16 Treasury checks, a “ghost gun” equipped with a 27-round magazine, and luxury goods purchased with stolen funds. She also used stolen cards to travel to Turks and Caicos and Aruba, later posting her trips, Rolex, and stacks of cash on Instagram.
Magdamit was arrested on July 1 while still using victims’ cards. A second search that day uncovered more stolen cards. She remains in custody and faces up to 30 years in federal prison when sentenced on October 27.
The case was investigated by the USPS Office of Inspector General, USPS Inspection Service, and Treasury Inspector General for Tax Administration.
