A 32-year-old Kent, Washington man was arraigned on May 11 in U.S. District Court in Seattle after being indicted on seven counts related to child sexual abuse material, attempted enticement of a minor, possession of controlled substances with intent to distribute, and unlawful possession of firearms. Mordien Kan Thach pleaded not guilty to all charges. The trial is set for July 6 before U.S. District Judge Tana Lin.
First Assistant U.S. Attorney Neil Floyd said, “This case is part of Iron Pursuit, a one-month, nationwide enforcement surge to find child victims of sex abuse and arrest child sex predators. In April 2026, more than 200 child victims were located and over 350 child sexual abuse offenders were arrested. In this Western Washington case, four victims were identified, and the investigation remains ongoing. If you abuse children, we will find you.”
According to records filed in the case, law enforcement began investigating Thach after a young teen contacted the FBI in Wisconsin about an adult who had sent and requested sexually explicit images online in August 2025. A search warrant executed at Thach’s residence in January 2026 led authorities to seize dealer quantities of cocaine and ketamine as well as several firearms—two reported stolen—and electronic devices containing images produced by Thach involving young teens from Western Washington and North Dakota.
Thach remains detained at the Federal Detention Center at SeaTac while awaiting trial. The indictment includes allegations only; he is presumed innocent unless proven guilty beyond a reasonable doubt.
Production of child pornography carries a mandatory minimum sentence of fifteen years up to thirty years; attempted enticement has a minimum ten-year sentence up to life; possession of child pornography may result in up to twenty years; drug distribution up to twenty years; unlawful firearm possession up to fifteen years.
The FBI is investigating the case as part of Operation Iron Pursuit. The Department partners with organizations such as the National Center for Missing and Exploited Children (NCMEC), which operates tip lines for reporting suspected exploitation through its hotline or website missingkids.orgLinks.
The public is urged by authorities to report suspected exploitation through the FBI's tipline or local field offices.
The U.S. Attorney for the Western District of Washington enforces federal criminal laws alongside law enforcement agencies, provides legal counsel for federal matters including civil rights protection, leads federal drug court programs with more than 150 staff members across offices in Seattle and Tacoma serving Western Washington communities such as Seattle and Tacoma according to the official website.
