A Wasilla man has pleaded guilty to distributing carfentanil, leading to the death of a 16-year-old girl and the near fatal overdose of another adult. Sean Mobley, 45, admitted in court to supplying what he believed was fentanyl powder but turned out to be carfentanil, a substance significantly more potent than fentanyl and used by veterinarians.
According to court documents, on November 14, 2024, Mobley provided an individual with .25 grams of the drug for distribution. The individual sold it to an adult victim for $100 at a Wasilla residence. After using the substance, the adult overdosed and suffered serious bodily injury.
Mobley then drove to a gas station where he dropped off the first individual and picked up a 16-year-old girl. He took her to an isolated location where both intended to use drugs together. Mobley gave her some of the powder; she immediately overdosed and lost consciousness. Believing she was dead, Mobley disposed of her body in a remote area before fleeing.
In addition to these charges, on January 28, 2025, Mobley was found with a shotgun in his vehicle despite having three prior felony convictions from 2002 and 2003. This led to a separate federal indictment for being a felon in possession of a firearm.
Federal grand juries returned indictments against Mobley in June and July on charges related to drug distribution resulting in death or serious bodily injury and firearms possession by a felon and unlawful drug user.
Mobley’s sentencing is set for January 22, 2026. He faces a mandatory minimum of 20 years in prison for distribution resulting in death or serious bodily injury and up to life imprisonment; he also faces up to 15 years for the firearm possession charge. Sentencing will be determined by a federal district court judge after reviewing guidelines and statutory factors.
U.S. Attorney Michael J. Heyman for the District of Alaska announced the plea alongside DEA Seattle Field Division Special Agent in Charge David F. Reames and Alaska State Trooper Colonel Maurice Hughes.
The case was investigated by the DEA Anchorage District Office and Alaska State Troopers. Assistant U.S. Attorneys Tom Bradley and Alana Weber are prosecuting with support from Alaska’s Department of Law Office of Special Prosecutions.
