A Los Angeles woman who flaunted luxury goods and wads of cash on social media has been sentenced to federal prison for stealing credit cards and cashing other people’s checks to fund her lavish lifestyle.

On Monday, Mary Ann Magdamit, 31, of Carson, admitted to conspiring to commit bank fraud while working as a U.S. Postal Service worker in Torrance.

From 2022 until July 2025, she stole mail containing checks, debit and credit cards, and personal identifying information, and then activated the stolen cards to make luxury purchases and take international trips to tropical locales.

She also sold some of the stolen cards to co-conspirators, and arranged for others to cash stolen checks using counterfeit identity documents, the U.S. Department of Justice said.

During a search of her apartment in December 2024, investigators found more than 130 stolen credit and debit cards, 16 U.S. Treasury checks, and a loaded unserialized Glock-style “ghost gun” with an extended magazine.

Federal agents also discovered luxury goods that were purchased with stolen cards, as well as evidence of her trips to Aruba and Turks and Caicos.

Despite the search of her home, Magdamit continued to use the stolen credit cards for her own purchases, the DOJ says. She was arrested on July 1, and an additional search of her apartment later that day yielded more stolen credit cards.

Magdamit remains in federal custody, and has agreed to forfeit a Rolex watch and other luxury goods after pleading guilty to her charges.

She is due in court on Oct. 27, and could face up to 30 years in federal prison.
