A former U.S. Postal Service employee from Carson has admitted to her role in a mail theft scheme that spanned over three years. Mary Ann Magdamit, 31, entered a guilty plea to one count of conspiracy to commit bank fraud stemming from her theft of checks and credit cards from mail she was entrusted to deliver.

Magdamit's criminal activity included activating stolen bank cards, making unauthorized purchases, selling some to accomplices, and cashing stolen checks with the aid of co-conspirators bearing fake IDs, according to details from the plea agreement and other court documents cited in a press release by the U.S. Attorney's Office. A raid on her apartment in December 2024 turned up a trove of evidence, including a cache of 133 stolen credit and debit cards, 16 checks from the U.S. Department of Treasury, and even a loaded "ghost gun", the thefts funding a lifestyle of luxury goods and exotic travel, some of it flaunted on social media platforms like Instagram.

After her initial arrest on July 1, subsequent to the discovery that Magdamit continued her fraudulent purchases, investigators seized more stolen financial paraphernalia upon searching her apartment again. A statement from the U.S. Attorney's Office details the forfeitures that Magdamit agreed to, including a Rolex watch and other luxury items obtained through her ill-gotten gains. An October 27 sentencing hearing awaits her, where she may face up to 30 years in federal prison.

Investigations leading to Magdamit's plea were conducted by The U.S. Postal Service Office of Inspector General, the U.S. Postal Inspection Service, and the Treasury Inspector General for Tax Administration, the coordinated effort underscoring the commitment to protecting the sanctity of mail and the integrity of the financial system. Assistant United States Attorney Andrew Brown of the Major Frauds Section will be leading the prosecution as the case moves to its final phase, with the public being kept informed via updates from Public Information Officer Ciaran McEvoy.
