According to the U.S. Attorney's Office for the District of Wyoming, 33-year-old Casper resident Alysha Ann Dahl was on Aug. 11, 2026, 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 in Casper. Federal officials said Dahl served as a distributor in a multi-county drug trafficking ring. Federal court documents cited by the office state that the Wyoming Department of Investigation (DCI), assisted by 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 on 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, according to the office. Agents determined that Dahl distributed more than 11 pounds of methamphetamine during the conspiracy. A federal complaint was filed Jan. 23, and Dahl was taken into federal custody Jan. 28, the office said. She waived indictment and pleaded guilty to an information May 19. In the factual basis supporting her guilty plea, Dahl admitted that on or about Oct. 17, 2025, she was within the District of Wyoming when she knowingly and intentionally possessed 500 grams or more of a mixture containing methamphetamine, that she knew the substance was methamphetamine, and that she intended to unlawfully distribute it to others. DCI, DEA and HSI investigated the case, which was prosecuted by Assistant U.S. Attorney Z. Seth Griswold. 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."

How we work

This site models an investigative reporter rather than a wire desk. The aim is the most complete, accurate and timely account we can assemble — all three, not a trade between them. Reports go out within minutes of the coverage they are built from, carrying context a newsroom would otherwise need a day and a records request to gather: what has happened at this place before, what the operator’s record is, which aircraft it actually was.

Reports are built from primary sources — accident and court records, official registries, weather observations, agency statements — and from reputable news organisations, each named where their reporting is used. Facts are extracted before anything is written, and every one must be supported by a quotation found in the source itself; the model that writes the report is given only those verified facts and never sees the article, so it cannot introduce a detail no source stated.

Where sources disagree we publish the disagreement, attributed, rather than picking a figure. Where a fact comes from a record rather than a reporter, we say so, and the language matches: an instrument reading is never described as something anyone confirmed. Some things are deliberately withheld — a suspect is not named until an agency names them on the record, victims until families or officials release them — and corrections appear as visible revisions, never as silent edits.

None of that makes a report true. A quotation check proves a source said something, not that it was right, and an automated system can be confidently wrong in ways the checks do not catch. If something here is wrong, the feedback above is how it gets found. The full methodology, including what we refuse to publish.
