A San Jose man has admitted he turned a rented Olympia P.O. box into the hub of a sham billing operation that siphoned money from unsuspecting companies across the West Coast, according to federal prosecutors. Johnny Q. Nguyen pleaded guilty Thursday to federal mail fraud after investigators said he mailed out phony government billing statements that persuaded thousands of businesses and charities to send checks to the Olympia address. Investigators intercepted 1,711 pieces of mail and nearly $395,295 in payments tied to the scheme, and Nguyen agreed to pay about $90,850 in restitution. Under his plea deal, prosecutors plan to ask for roughly a 33-month prison sentence when he is sentenced in May.
How the scam worked
According to the U.S. Attorney’s Office, prosecutors say Nguyen, 50, spent the fall of 2024 pumping out mass mailings on fake state-government letterhead that looked like official notices. The letters claimed recipients owed registration and filing fees, then instructed them to make checks payable to an LLC Nguyen had formed called “Business Entities” and mail the payments to a P.O. box he rented in Olympia. On paper, it looked like routine state paperwork; in reality, it routed straight into Nguyen’s operation, officials say.
Money seized and deposits
Court records and regional reporting show that Nguyen deposited about 350 checks from Washington victims totaling roughly $82,210 and cashed about 60 checks from California victims worth about $8,640. Investigators also seized another 1,711 pieces of mail containing checks and money orders valued at $395,295, according to the Tri-Cities Area Journal of Business. Those intercepted envelopes represent the bulk of nearly $400,000 that authorities say was headed for accounts tied to the scam before the plug was pulled.
Plea, flight and what is next
Nguyen entered his guilty plea Thursday in federal court, and under the plea agreement prosecutors will recommend a 33-month sentence. Chief U.S. District Judge David G. Estudillo is scheduled to sentence him on May 22, 2026, as reported by KOMO News. Prosecutors also say that while the case was pending Nguyen boarded a flight from San Francisco to Taipei on June 24, 2025, using a passport he had been ordered to surrender. He was detained in Taipei, then returned to California and later released on pretrial supervision.
Advice for businesses
The U.S. Attorney’s Office and the U.S. Postal Inspection Service are urging businesses and nonprofits to slow down when something that looks like government mail arrives with a demand for money. They advise verifying any supposed government bill by calling the agency using contact information posted on its official website and reporting suspicious mail or solicitations to law enforcement. State officials have previously warned that red flags such as non-.gov web addresses and incorrect return addresses are classic markers of a scam, and the secretary of state’s office publishes guidance on how to spot fraudulent solicitations, according to reporting.
Legal implications
Mail fraud and money-laundering counts each carry maximum penalties of up to 20 years in prison, although under Nguyen’s plea prosecutors will ask for a 33-month term. The final sentence is up to the judge, KOMO News reports. Victims who mailed payments to the Olympia P.O. box are eligible for restitution, and court records show Nguyen has agreed to reimburse about $90,850 to those victims.
