Southern California Man Pleads Guilty to Fentanyl and Methamphetamine Distribution Conspiracy

Devlin Hosner, 36, of Indio, pleaded guilty today to conspiring to distribute fentanyl and methamphetamine, U.S. Attorney Eric Grant announced.

According to court documents, between 2020 and 2022, Hosner and his co-conspirator Holly Adams, 35, of Palm Desert, operated vendor accounts on the dark web marketplaces known as ToRReZ and Dark0de. Hosner and Adams generated hundreds of thousands of dollars selling counterfeit oxycodone pills pressed with fentanyl, after which they laundered the proceeds using cryptocurrency mixers, wallets, and other online tools.

In September 2021, law enforcement officers executed a search warrant at an address where Hosner and Adams resided. After the officers announced their presence, Hosner attempted to impede their entry while Adams destroyed pills by pouring them into a chemical solution. Adams and Hosner were arrested and subsequently released by state authorities and resumed selling fentanyl on the dark web a few months later while they were unknowingly under investigation by federal law enforcement agents.

In March 2022, federal agents executed a search warrant at a hotel room in Riverside County where Hosner and Adams were temporarily residing. Officers seized nearly a kilogram of fentanyl-pressed oxycodone pills and 60 grams of methamphetamine from this hotel room. Hosner and Adams were arrested on federal charges.

This case is the product of an investigation by the Northern California Illicit Digital Economy (NCIDE) Task Force, a previously existing task force that included agents from the Internal Revenue Service - Criminal Investigation, Homeland Security Investigations, the Federal Bureau of Investigation, the United States Postal Inspection Service, the United States Postal Service Office of Inspector General, and the Drug Enforcement Administration. The NCIDE Task Force was a federal task force focused on targeting all forms of illicit dark web and cryptocurrency activity in the Eastern District of California and beyond. Assistant U.S. Attorney Sam Stefanki is prosecuting the case.

Adams previously pleaded guilty to conspiring to distribute fentanyl and to launder the resulting proceeds.  In June 2025, the district court sentenced her to serve 12 years in prison.

Hosner is scheduled to be sentenced by Senior U.S. District Judge John A. Mendez on March 24, 2026. Hosner faces a mandatory minimum statutory penalty of 10 years in prison and a maximum statutory penalty of life in prison, as well as a $1 million fine. The actual sentence, however, will be determined at the discretion of the court after consideration of any applicable statutory factors and the federal Sentencing Guidelines, which take into account a number of variables.
