Liu’s official responsibilities were limited to information-technology support, so they did not have access to modify any government computer. Port Director Theodore Cummings made the restriction abundantly clear to Liu in a written order: “Please do not move any computers or computer parts.” However, criminals rarely listen.
Hidden surveillance cameras captured Liu opening government computers and swapping hardware during the midnight shift. The perpetrator would take the systems to a training room to commit the crime. One camera recording showed Liu using a screwdriver to scrape thermal paste off a processor and installing a replacement chip in one system. Meanwhile, another recording caught Liu removing a memory module from a system and storing it in their desk drawer.
According to the affidavit, investigators found that thirty-nine computers had their processors replaced, six machines with memory modules swapped, and eight had hard drive changes. The original systems used Raptor Lake Refresh chips but were later discovered to have older hardware, sometimes downgraded to Pentium chips. Beyond the processor swap, other computers had less memory and storage capacity than their original configurations.
Instead of trying to sell the stolen hardware on the open second-hand market, Liu used a less conspicuous approach: Newegg’s Trade-In program. According to investigators, Liu sent 13 emails between a personal account and an official CBP email address containing shipping labels and trade-in receipts for processor models matching the missing components from the government computers.

The Newegg trade-in offers varied between $200 and $210 per processor. According to the transaction records from the U.S. retailer, Liu traded in Core i7 Raptor Lake Refresh chips 16 times over 14 months, from May 2025 to July 2026. Investigators also found three $200 credits from Newegg in Liu's American Express records.
During an interview, Liu confessed to replacing hardware in the government computers with lower-performing parts bought on Amazon and Newegg. They also acknowledged submitting the government-owned parts to Newegg's Trade-In program. At first, Liu claimed their actions were motivated by a desire to improve the computers' performance and how long computer repairs took. However, they later admitted that the changes resulted in degraded performance.
