A Wasilla man has been sentenced to 30 years in federal prison for distributing carfentanil, a potent opioid, which led to the fatal overdose of a minor and the near-fatal overdose of an adult. Sean Mobley, 45, will also serve lifetime court-mandated supervision after his release.
Court documents show that on November 14, 2024, Mobley agreed to supply fentanyl powder to another individual for distribution. The two drove to a residence in Wasilla where the intermediary sold the powder to an adult victim for $100. The adult used the substance and overdosed but was revived with Naloxone. Authorities later determined that the substance was actually carfentanil, which is used by veterinarians and is significantly more potent than fentanyl.
After this incident, Mobley went to a gas station where he picked up a 16-year-old girl. He took her to an isolated location with the intention of using drugs together and provided her with some of the same substance. She overdosed and died within minutes. Mobley then disposed of her body in a remote area before fleeing.
Mobley was later found in possession of a shotgun on January 28, 2025. At that time, he was prohibited from having firearms due to three prior felony convictions.
On June 10, a federal grand jury indicted Mobley on charges related to drug distribution resulting in death and serious bodily injury. A second indictment followed on July 17 for firearm possession as a felon and as an unlawful drug user. On October 9, Mobley pleaded guilty to two counts of distribution resulting in death or bodily injury and one count of possessing a firearm as a felon.
The court ordered Mobley to serve 30 years for the distribution charges and two years concurrently for the firearm charge.
“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 U.S. 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—if you endanger Alaskans, the consequences will be severe.”
“Mr. Mobley showed complete disregard for human life when he provided the deadly dose of carfentanil to the 16-year-old victim,” said Robert A. Saccone, Special Agent in Charge, DEA Seattle Field Division. “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. DEA was proud to work with our partners at the Alaska State Troopers and the U.S. Attorney’s Office for the District of Alaska to seek justice for the young victim in this case. 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.”
“This significant sentence reflects the danger and seriousness of distributing illicit drugs like carfentanil,” said Alaska State Troopers Colonel Maurice Hughes.“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 investigation involved both federal Drug Enforcement Administration agents from Anchorage and Alaska State Troopers.
Prosecution was handled by Assistant U.S. Attorneys Tom Bradley and Alana Weber with support from Alaska’s Department of Law Office of Special Prosecutions.
This case falls under Operation Take Back America—a national initiative led by the Department of Justice focused on combating illegal immigration, dismantling criminal organizations involved in drug trafficking or violent crime, and protecting communities across America.
