Justice served in bulk meth attempt: Casper resident sentenced to more than 12 years

CASPER, Wyo. - A Casper woman will serve more than 12 years in federal prison for her role as a distributor in a multi-county drug trafficking ring, federal officials said.

Alysha Ann Dahl, 33, of Casper, was sentenced to 151 months in federal prison, followed by five years of supervised release, for possession with intent to distribute methamphetamine. U.S. District Court Judge Scott W. Skavdahl imposed the sentence Aug. 11 in Casper.

According to federal court documents, the Wyoming Department of Criminal Investigation (DCI), with assistance from the Drug Enforcement Administration (DEA), Homeland Security Investigations (HSI) and multiple state and local agencies, investigated a drug trafficking organization operating in Wyoming and Colorado.

Law enforcement intercepted and arrested Dahl Nov. 10, 2025, near Casper. After a search of the vehicle she was traveling in, investigators found scales, syringes and nearly half a pound, or about 205 grams, of methamphetamine. Agents determined Dahl distributed more than 11 pounds of methamphetamine during the conspiracy.

A federal complaint was filed Jan. 23, and she was taken into federal custody Jan. 28. Dahl waived indictment and pleaded guilty to information May 19. Dahl provided a factual basis in support of her guilty plea in which she admitted that on or about October 17, 2025, she was within the District of Wyoming when she knowingly and intentionally possessed 500 grams or more of a mixture containing methamphetamine. She knew the substance was methamphetamine, and she intended to unlawfully distribute it to others. DCI, DEA and HIS investigated the crime and Assistant U.S. Attorney Z. Seth Griswold prosecuted the case.

U.S. Attorney Darin Smith said, "This operation proves that we will not let illegal drugs tear apart our communities. By working closely with local and state police, we are taking dealers off the streets and protecting Wyoming families. Our combined forces will continue to track down and punish anyone who brings these dangers into our neighborhoods."
