Final Defendants Plead Guilty in $65 Million Multinational Fraud Ring Targeting Thousands of Seniors

SAN DIEGO – The last of 25 defendants in a $65 million fraud scheme that preyed on thousands of elderly victims in San Diego and beyond admitted their crimes on Friday, marking a significant step toward accountability in the sprawling international case that was bolstered by YouTube scambaiters.

The 25 defendants – mostly Chinese nationals – were arrested in August 2025 after a nationwide, weeklong takedown in California, New York, Texas and Michigan. Three charged defendants remain fugitives.

Haotian Zhang and Zetian Zhang pleaded guilty in federal court on Friday. Haotian Zhang, a Chinese national, was remanded into custody by U.S. District Judge Todd W. Robinson following his guilty plea. Over the past few months, eight other defendants charged as part of the investigation—Guangli Lin, Cheng Li, Weining Su, aka “Ning Ma,” Hongsen Cao, Xinyu Shao, Renchao Chen, Dexiao Lin, Zhiyi Zhang—have also pleaded guilty in federal court for their roles in the same fraud and money laundering scheme, and two defendants—Huajian Chen and Jianhao Gao—recently pleaded guilty to operating an unlicensed money transmission business.

Videos by YouTubers from Scammer Payback and Trilogy Media helped law enforcement identify multiple defendants and uncover the structure of the fraud conspiracy. Indeed, in their respective plea agreements, defendants Zhiyi Zhang and Huajian Chen, shown below, admitted to being in YouTube videos in which they were confronted about their involvement in the charged criminal activity.

Operating since at least 2019 and rooted in Southern California, the criminal network—primarily composed of Chinese nationals, many in the U.S. illegally—worked closely with India-based scam call centers. Fraudsters who took the calls posed as technical support agents, government officials, or bank employees, according to court records. Once a victim had been defrauded, victims were instructed to withdraw bulk cash, to conceal the cash in packages, and to send cash-laden packages via express mail carriers to names and addresses provided by the conspirators. The recipient names were fictitious names corresponding with fake IDs. The recipient addresses were for the short-term rental locations. In their respective plea agreements, defendants admitted that to facilitate receipt of victim packages, members of the conspiracy booked short-term rentals in a hub-and-spoke pattern: a hub would be booked for approximately one week; spoke locations would be booked nearby for shorter stays. After some time, members of the conspiracy would relocate to a new location and continue the pattern.

In August 2025, federal agents coordinated a sweeping nationwide takedown of the investigation, including arrests in Southern California, Texas, Michigan and New York. The investigation started in December 2020 after an elderly victim contacted an express mail carrier after being defrauded into sending bulk cash in the mail. That led to the discovery of 11 total packages, containing approximately $135,000 in cash. Each of the packages was addressed to a fake name and a short-term rental in the San Diego area. The investigation also led to the discovery of several YouTube videos posted in 2020 and 2021 that helped identify other members of the conspiracy. YouTuber Pierogi from “Scammer Payback”— which is known for exposing scammers—documented his interaction with the India-based scam call centers. In a series of videos, Pierogi from Scammer Payback teamed up with two other YouTubers from “Trilogy Media” to publish videos on their respective YouTube channels.

In coordinated sting operations, Scammer Payback and Trilogy Media baited fraudsters, confronted them on camera, and published those videos to their respective YouTube channels. Videos posted in 2020 and 2021 helped law enforcement identify Zhiyi Zhang, Dudu Chen and Huajian Chen. The videos also helped shed light on how the conspiracy operated and led to the identification of high-level members of the organization. After defrauding victims, members of the conspiracy also laundered the proceeds of the fraud scheme. Specifically, members of the conspiracy set up the operation to conceal the fact that the cash-laden packages were obtained through fraud. Members of the conspiracy also used the proceeds of the fraud scheme to pay other members of the conspiracy and to compensate them for travel expenses used to further the fraud scheme. Sentencing hearings for each of the defendants are scheduled before U.S. District Judge Todd W. Robinson as set forth below.
