A 50-year-old San Jose man has pleaded guilty to federal mail fraud charges after admitting he ran a sham billing operation that siphoned money from thousands of unsuspecting businesses and charities across the West Coast. Johnny Q. Nguyen rented a P.O. box in Olympia, Washington and used it to collect nearly $400,000 in fraudulent payments from victims who received phony government billing statements demanding registration and filing fees.

Why it matters

This case highlights the growing problem of sophisticated mail fraud schemes targeting small businesses and nonprofits, who can be vulnerable to official-looking demands for payment. It also raises concerns about the ability of scammers to evade authorities, as Nguyen attempted to flee the country while the case was pending.

The details

According to prosecutors, Nguyen spent the fall of 2024 sending out mass mailings on fake state government letterhead that looked like official notices. The letters claimed recipients owed registration and filing fees, and instructed them to make checks payable to an LLC Nguyen had formed called 'Business Entities' and mail the payments to his Olympia P.O. box. Investigators intercepted 1,711 pieces of mail containing nearly $395,295 in fraudulent payments before they could reach Nguyen's accounts.

  • In the fall of 2024, Nguyen began sending out the fraudulent mass mailings.
  • On June 24, 2025, while the case was pending, Nguyen attempted to board a flight from San Francisco to Taipei but was detained in Taipei and later returned to California.
  • On February 21, 2026, Nguyen pleaded guilty to federal mail fraud charges.
  • Nguyen is scheduled to be sentenced on May 22, 2026.
