Ex-USPS Worker Pleads Guilty to Stealing 133 Credit Cards, Treasury Checks

Mary Ann Magdamit, a former U.S. Postal Service letter carrier in Torrance, California, pleaded guilty to conspiracy to commit bank fraud after stealing checks, credit cards, and personal identifying information from the mail over a three-year period. She used the stolen cards to fund a lavish lifestyle, including luxury purchases and international trips to Turks and Caicos and Aruba, and sold some of the stolen cards to accomplices who cashed checks with counterfeit identity documents. Law enforcement seized 133 stolen credit and debit cards, 16 U.S. Treasury checks, a loaded ghost gun, and luxury goods from her apartment during a December 2024 raid. Despite the raid, Magdamit continued to use stolen cards until her arrest in July 2025 and has agreed to forfeit luxury items like a Rolex watch. Her sentencing hearing is scheduled for October 27, and she faces up to 30 years in federal prison. The case was investigated by the U.S. Postal Service Office of Inspector General, the U.S. Postal Inspection Service, and the Treasury Inspector General of Tax Administration.
