More on this incident

Alysha Ann Dahl, 33, of Casper, Wyoming, was to 151 months in federal prison followed by five years of supervised release for possession with intent to distribute methamphetamine, according to press release , issued Aug. 14, 2026, by the U.S. Attorney's Office for the District of Wyoming. U.S. District Court Judge Scott W. Skavdahl imposed the sentence Aug. 11, 2026, in Casper, the release states. According to the same release and the federal court documents it cites, law enforcement officers intercepted and arrested Dahl on Nov. 10, 2025, near Casper. A search of the vehicle she was traveling in yielded 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, which the office said operated across Wyoming and Colorado. A federal complaint was filed on Jan. 23, and she was taken into federal custody on Jan. 28. Dahl waived indictment and pleaded guilty on May 19 to an information. In support of her plea, the release states, Dahl admitted that on or about Oct. 17, 2025, she knowingly and intentionally possessed 500 grams or more of a mixture containing methamphetamine within the District of Wyoming and intended to distribute it to others. The Wyoming Department of Investigation, the Drug Enforcement Administration, and Homeland Security Investigations investigated the case, with assistance from multiple state and local agencies, and Assistant U.S. Attorney Z. Seth Griswold prosecuted it. In the Aug. 14, 2026, announcement, 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."

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 β€” 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 β€” accident and court records, official registries, weather observations, agency statements β€” 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 β€” a suspect is not named until an agency names them on the record, victims until families or officials release them β€” 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.
