A Wasilla man has pleaded guilty to distributing carfentanil, a powerful synthetic opioid, which led to the death of a 16-year-old girl and the near fatal overdose of another adult. The individual, Sean Mobley, 45, also admitted guilt to being a felon in possession of firearms in connection with a separate federal indictment.
According to court documents, on November 14, 2024, Mobley supplied an individual with what he believed was fentanyl powder but was actually carfentanil. Carfentanil is an opioid used by veterinarians that is significantly more potent than fentanyl. Mobley and the individual drove to a residence in Wasilla where the substance was sold for $100 to an adult victim who later overdosed and suffered serious bodily injury.
After this transaction, Mobley went to a gas station where he picked up a 16-year-old girl. He then took her to an isolated location where they intended to use drugs together. The minor used some of the substance and immediately lost consciousness from an overdose. Believing she had died, Mobley left her body in a remote area before fleeing.
Mobley was later found on January 28, 2025, in possession of a shotgun while operating a vehicle. With three prior felony convictions from 2002 and 2003, his possession of the firearm constituted another federal offense.
On June 10, a federal grand jury indicted Mobley for distribution resulting in death and serious bodily injury. A separate indictment returned on July 17 charged him with being both a felon and an unlawful drug user or addict in possession of a firearm.
Mobley's sentencing is scheduled for January 22, 2026. He faces at least 20 years in prison—potentially up to life—for distributing drugs resulting in death or serious injury. For the firearm charge alone he could receive up to 15 years in prison. Sentencing will be determined by a federal district court judge based on U.S. Sentencing Guidelines as well as other legal considerations.
U.S. Attorney Michael J. Heyman for the District of Alaska stated: “The DEA Anchorage District Office and the Alaska State Troopers investigated the case.” Special Agent David F. Reames of the DEA Seattle Field Division and Colonel Maurice Hughes of Alaska State Troopers joined Heyman in making this announcement.
Prosecution is being handled by Assistant U.S. Attorneys Tom Bradley and Alana Weber with support from the State of Alaska Department of Law’s Office of Special Prosecutions.
