Federal prosecutors say a Houston firearms ring quietly moved about 170 guns and several thousand rounds of ammunition, and that at least some of that firepower was headed toward North Korea. According to an indictment, the operation allegedly relied on straw purchasers and even the purchase of a local gun store in order to steer specific weapons into the pipeline. Seven people are now charged, including several Chinese nationals and one U.S. citizen, and court records show at least one defendant has already appeared in federal court in Houston.
In a press release, the U.S. Attorney’s Office for the Southern District of Texas identified 39-year-old Shenghua Wen as the alleged ringleader and noted that his U.S. visa expired in 2013. The same release names the six other people charged: 24-year-old Sifu Zhao, 40-year-old Yiyang Wu, 27-year-old Mingtong Tan, 60-year-old Jin Yang, 36-year-old Max Mingze Li and 51-year-old Richard Arredondo. Prosecutors say a federal grand jury returned the indictment on October 8, 2025. U.S. Attorney’s Office, Southern District of Texas.
How Prosecutors Say the Ring Operated
According to prosecutors, Wen and his girlfriend did not just shop at a gun store, they bought one, then allegedly used it as home base for a straw-purchasing network. Investigators say Wen directed straw buyers to pick up specific pistols that were later resold within the group or routed through another Houston gun dealer for resale. Between 2023 and 2024, the group allegedly acquired about 170 firearms and several thousand rounds of ammunition, according to court records cited by Click2Houston.
Charges, Possible Penalties and the Investigation
Wen and Jin Yang are charged with conspiracy and with conspiracy to commit firearms trafficking. Prosecutors say those counts carry maximum prison terms of up to five years for conspiracy and up to 15 years for conspiracy to traffic firearms. Wen is also accused on seven separate counts of aiding and abetting false statements to a federally licensed firearms dealer.
The remaining defendants face charges that include conspiracy and making false statements to gun sellers. The indictment notes that each count carries a potential fine of up to 250,000 dollars. The Bureau of Alcohol, Tobacco, Firearms and Explosives led the investigation, with assistance from Homeland Security Investigations and the Houston Police Department, according to the U.S. Attorney’s Office. U.S. Attorney’s Office, Southern District of Texas.
Previous North Korea Case Adds Context
This Southern District of Texas indictment lands alongside a separate federal case that already resulted in prison time. Prosecutors with a different office, the U.S. Attorney’s Office in Los Angeles, previously announced that a Chinese national named Shenghua Wen pleaded guilty in June and was sentenced in August 2025. In that earlier case, they said Wen arranged shipments of firearms, ammunition and export-controlled technology to North Korea.
That Los Angeles release also stated that Wen purchased a firearms business in Houston in May 2023 and used purchases made in Texas as part of his export schemes. U.S. Attorney’s Office, Central District of California.
What Comes Next in the Houston Case
Prosecutors have emphasized that, for now, the indictment is simply an accusation. All seven defendants are presumed innocent while the case moves forward in federal court. Assistant U.S. Attorney John Ganz is listed as the prosecutor handling the matter, and additional court dates and filings were not immediately available, according to Click2Houston.
