Jan. 25, 2026 -A Wasilla man has been sentenced to 30 years in federal prison and will spend the remainder of his life under court-mandated supervision after his release for distributing carfentanil that led to the death of a 16-year-old girl and the near-fatal overdose of an adult.
Sean Mobley, 45, was sentenced following his guilty plea to two counts of distribution resulting in death or serious bodily injury and one count of being a felon in possession of a firearm.
According to court documents, the case began on Nov. 14, 2024, when Mobley agreed to supply an individual with what he believed was fentanyl powder for distribution to a third party. Mobley and the intermediary drove to a residence in Wasilla, where the intermediary sold the powder to an adult victim for $100.
Shortly after the transaction, the adult victim used the substance and overdosed. The victim was revived with naloxone. Law enforcement later determined the substance was not fentanyl, but carfentanil, which is a powerful synthetic opioid used by veterinarians that is approximately 100 times more potent than fentanyl.
After that overdose, Mobley drove to a local gas station, dropped off the intermediary, and picked up a 16-year-old girl. He then drove her to an isolated location (an ATV trail) with the intention of using drugs together. Mobley provided the minor with the substance containing carfentanil.
The teenager used the drug, overdosed, and died within minutes.
Instead of seeking medical help, Mobley dumped her body in a remote area along the trail and fled.
Following the overdoses, Mobley was later found in possession of a shotgun on Jan. 28, 2025. Already a felon, he was prohibited from possessing a firearm under federal law due to three prior convictions.
A federal grand jury returned an indictment on June 10 charging Mobley with distribution resulting in death and serious bodily injury. A second indictment was returned on July 17 charging him with being a felon in possession of a firearm and being an unlawful drug user in possession of a firearm.
On Oct. 9, Mobley pleaded guilty to all charges.
During sentencing, the court ordered Mobley to serve three decades in prison on the distribution charges, with an additional two-year sentence for the firearm charge, to be served concurrently. He will remain under lifetime court-mandated supervision following his release from federal custody.
“Mr. Mobley acted callously and without remorse. He peddled whatever he could get his hands on to make a quick buck, including deadly drugs, with zero regard for human life,” said US Attorney Michael J. Heyman for the District of Alaska. “Let this be a warning— whether you lead an international drug trafficking organization or are a street-level dealer —I f you endanger Alaskans, the consequences will be severe.”
DEA Seattle Field Division Special Agent in Charge Robert A. Saccone said the case reflects the deadly consequences of synthetic opioid trafficking.
“Mr. Mobley showed complete disregard for human life when he provided the deadly dose of carfentanil to the 16-year-old victim,” Saccone said. “Not only did the teenage girl overdose in his vehicle, but instead of trying to get help, he disposed of her body in a remote area and fled. Mr. Mobley will spend the next 30 years paying for his complete disregard for human life. Let this sentence also send a message to other drug traffickers: you will be held accountable for peddling this poison.”
Alaska State Troopers Colonel Maurice Hughes called the sentence a warning about the danger of synthetic opioids.
“This significant sentence reflects the danger and seriousness of distributing illicit drugs like carfentanil,” Hughes said. “These drugs upend lives and devastate communities across our great state. Your Alaska State Troopers will continue to hold offenders accountable and keep dangerous narcotics out of Alaska.”
The case was investigated by the DEA Anchorage District Office and the Alaska State Troopers. It is being prosecuted by Assistant US Attorneys Tom Bradley and Alana Weber, with assistance from the State of Alaska Department of Law, Office of Special Prosecutions.
The prosecution falls under Operation Take Back America, a Department of Justice initiative.
