A Wasilla man has pleaded guilty to distributing carfentanil, a synthetic opioid, which led to the death of a 16-year-old girl and the near-fatal overdose of an adult. Sean Mobley, 45, also admitted guilt to being a felon in possession of firearms under a separate indictment.
Court records show that on November 14, 2024, Mobley agreed to provide an individual with 0.25 grams of what he believed was fentanyl powder for distribution. The substance turned out to be carfentanil, an opioid used by veterinarians and significantly more potent than fentanyl.
Mobley and the individual traveled to a residence in Wasilla where the substance was sold for $100 to an adult victim. The victim overdosed shortly after using the drug and suffered serious bodily injury.
After this incident, Mobley went to a local gas station, dropped off the individual who had assisted him, and picked up a 16-year-old girl. He took her to a remote location with the intention of using drugs together. He provided her with some of the substance, leading her to overdose and lose consciousness immediately. Believing she had died, Mobley left her body in a remote area before fleeing.
On January 28, 2025, Mobley was found with a shotgun inside his vehicle while operating it. With three prior felony convictions from 2002 and 2003, he is prohibited from possessing firearms.
A federal grand jury indicted Mobley on June 10 for distribution resulting in death and serious bodily injury. Another indictment followed on July 17 for being both a felon in possession of a firearm 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 imprisonment—potentially up to life—for distributing drugs resulting in death or serious injury, as well as up to 15 years for illegally possessing firearms. The final sentence will be determined by a federal district court judge based on U.S. Sentencing Guidelines and statutory factors.
The announcement was made by U.S. Attorney Michael J. Heyman of the District of Alaska; Special Agent in Charge David F. Reames of the DEA Seattle Field Division; and Alaska State Trooper Colonel Maurice Hughes.
The case was investigated by the DEA Anchorage District Office along with Alaska State Troopers. Assistant U.S. Attorneys Tom Bradley and Alana Weber are prosecuting with support from the State of Alaska Department of Law’s Office of Special Prosecutions.
