She was supposed to deliver the mail. Instead, federal prosecutors say she delivered herself a luxury life — at the expense of hundreds of unsuspecting Americans.
Mary Ann Magdamit, 31, a former letter carrier at the Torrance Main Post Office in Southern California, admitted Monday to an audacious three-year scheme: stealing mail containing checks, personal identifying information, and credit and debit cards, then using them to bankroll a high-end lifestyle of Rolex watches, champagne poolside, and tropical vacations.
Between 2022 and July 2025, authorities say Magdamit rifled through letters and packages meant for her customers, pocketing valuables and confidential financial details. She allegedly activated stolen credit cards online, using them for expensive purchases — and sometimes selling them to co-conspirators who helped cash stolen checks and forge counterfeit IDs in victims’ names.
Instagram as a Trophy Case
Rather than hide her alleged crimes, Magdamit flaunted the spoils.
On Instagram, she posted photos of herself lounging by resort pools in Turks and Caicos and Aruba, champagne in hand. In one image, wearing a Yankees cap, she grinned at the camera while holding a thick stack of $100 bills to her ear like a cellphone. In another, the cash spilled across her lap as she sat in her car.
The US Attorney’s Office for the Central District of California says these luxuries were all funded by the theft of other people’s mail.
A Cache of Stolen Goods — and a ‘Ghost Gun’
In December 2024, law enforcement raided Magdamit’s apartment. What they found stunned even seasoned investigators:
- 133 stolen credit and debit cards
- 16 US Treasury checks
- A “ghost gun” — an untraceable Glock clone with a 27-round extended magazine
Despite the bust, prosecutors say Magdamit stayed free — and kept spending. By July 2025, investigators discovered she was still making purchases with victims’ cards.
On July 1, federal agents arrested her again, seizing even more stolen credit cards from her home.
The Charges — and the Stakes
Magdamit now faces one count of conspiracy to commit bank fraud, a federal charge carrying a maximum sentence of 30 years in prison.
Authorities have not said whether any of her alleged accomplices have been arrested.
Her case comes just months after another former USPS worker, Hachikosela Muchimba, was convicted in Washington, DC, of stealing $1.6 million in checks to fund an equally extravagant lifestyle — including international travel, luxury hotels, and nights at gentlemen’s clubs.
Betraying a Federal Trust
Postal workers are among the most trusted public servants in the US, with strict federal laws protecting the sanctity of the mail. The allegations against Magdamit represent a stark betrayal of that trust — one made worse, prosecutors say, by her brazen public display of the wealth she allegedly stole.
“Every check, every card, every piece of mail she took was meant for someone counting on the US Postal Service to deliver it safely,” said one law enforcement official familiar with the case. “Instead, she turned the system into her personal ATM.”
Magdamit has not publicly commented on the charges, and no sentencing date has been set.
If convicted, her social media feed may one day swap sunny beaches and champagne for the steel bars and cinderblock walls of a federal prison.
