A former United States Postal Service (USPS) employee has pleaded guilty to accepting bribes in connection with USPS service contracts, according to an announcement from Ryan Raybould, U.S. Attorney for the Northern District of Texas.
Zechariah Yi, 52, of Aurora, Colorado, entered his plea on Tuesday to one count of receiving a bribe by a public official. Yi was indicted in March 2025 for accepting payments related to the awarding of USPS service contracts to certain trucking companies.
Court documents state that while working as a Senior Network Operations Analyst at USPS, Yi solicited and received about $1.5 million in kickbacks from owners and associates of three trucking companies. In exchange, he agreed to help these companies secure USPS service contracts. The total value of the contracts awarded was approximately $15 million.
Yi is scheduled for sentencing on March 26, 2026, and faces up to fifteen years in federal prison.
This case marks the fourth guilty plea connected to this bribery scheme. Previously, another USPS employee named Tai Rho and two trucking company owners—Wan Jin Yoon and Hong Jin Yoon—pleaded guilty to conspiracy to commit honest services wire fraud. Each faces up to five years in federal prison and will be sentenced in early 2026.
The investigation was conducted by the FBI Dallas Field Office and the United States Postal Service - Office of the Inspector General. Assistant U.S. Attorneys Marty Basu and Joshua Detzky are prosecuting the case.
