Devlin Hosner, a 36-year-old resident of Indio, California, pleaded guilty to conspiring to distribute fentanyl and methamphetamine, according to an announcement from U.S. Attorney Eric Grant.
Court documents indicate that between 2020 and 2022, Hosner and Holly Adams, 35, of Palm Desert, managed vendor accounts on the dark web marketplaces ToRReZ and Dark0de. The pair sold counterfeit oxycodone pills containing fentanyl and laundered the proceeds using cryptocurrency-related tools.
In September 2021, law enforcement executed a search warrant at the residence shared by Hosner and Adams. Authorities reported that Hosner tried to block their entry while Adams attempted to destroy evidence by dissolving pills in a chemical solution. Both were arrested but released by state authorities. After their release, they resumed selling fentanyl on the dark web without knowing they were under federal investigation.
Federal agents later executed another search warrant in March 2022 at a hotel room in Riverside County where the two were staying temporarily. Officers seized nearly one kilogram of fentanyl-laced oxycodone pills and 60 grams of methamphetamine from the room. Both individuals were then arrested on federal charges.
The investigation was led by the Northern California Illicit Digital Economy (NCIDE) Task Force. This task force included members from several federal agencies such as the Internal Revenue Service – Criminal Investigation, Homeland Security Investigations, Federal Bureau of Investigation, United States Postal Inspection Service, United States Postal Service Office of Inspector General, and Drug Enforcement Administration. The NCIDE Task Force targeted illicit activities involving the dark web and cryptocurrency in the Eastern District of California and beyond.
Assistant U.S. Attorney Sam Stefanki is prosecuting this case.
Adams previously pleaded guilty to conspiracy to distribute fentanyl and money laundering related to these activities. In June 2025, she was sentenced to serve 12 years in prison.
Hosner is scheduled for sentencing before Senior U.S. District Judge John A. Mendez on March 24, 2026. He faces a mandatory minimum sentence of ten years in prison with a maximum possible penalty of life imprisonment and up to a $1 million fine. The final sentence will be determined by the court after considering statutory factors and federal Sentencing Guidelines.
