A Casper woman who federal investigators say distributed more than 11 pounds of methamphetamine through a drug network stretching across Wyoming and into Colorado will spend more than 12 years in federal prison.
Alysha Ann Dahl, 33, was sentenced Tuesday by U.S. District Court Judge Scott Skavdahl.
Dahl wasn't the only Casper distributor to receive a lengthy federal prison sentence.
Bryan James Hackleman, identified by federal prosecutors as a primary distributor in the organization, was sentenced July 28 to the same prison term: 151 months.
Investigators attributed more than 16 pounds of methamphetamine to Hackleman.
Together, that's more than 27 pounds of meth attributed to the two Casper distributors.
By The Pound
The investigation caught up with Dahl near Casper on Nov. 10, 2025.
When law enforcement intercepted the vehicle in which she was traveling, a search turned up scales, syringes and nearly half a pound of methamphetamine — about 205 grams.
Hackleman was arrested near Casper that same day. Federal prosecutors reported the same combination of evidence in announcing his sentence: Scales, syringes and roughly 205 grams of meth.
The roughly half-pound seized that day, however, represented only a fraction of what investigators ultimately attributed to the pair.
By the time the federal cases were resolved, the total was 27 pounds.
And Dahl's own guilty plea showed the November bust was only part of the picture.
She admitted that less than a month earlier, on Oct. 17, she had possessed at least 500 grams of a mixture containing methamphetamine in Wyoming with the intent to distribute.
That's more than twice the amount investigators reported seizing in November.
The federal case followed quickly. A criminal complaint was filed Jan. 23, Dahl was taken into federal custody Jan. 28, and on May 19 she waived her right to grand-jury indictment and pleaded guilty to possession with intent to distribute.
‘Boogeyman’
Dahl's history with methamphetamine and law enforcement stretches back years — and includes a bizarre fake kidnapping.
In May 2018, Dahl's father reported receiving threatening messages from her phone from a supposed kidnapper calling himself “Boogeyman,” who claimed Dahl owed $350 and demanded money for her release.
A Casper police sergeant noticed the amounts being demanded corresponded with what investigators identified as street prices for various quantities of methamphetamine. Police pinged Dahl's phone and found her unharmed at a friend's house, where investigators said she eventually admitted concocting the kidnapping to “hustle” her father for money. She was arrested on recommended blackmail and interference charges.
Three months later, Dahl was arrested again after police investigating a vehicle chase found methamphetamine in multiple containers in her backpack.
Dahl told police she'd been using methamphetamine since she was 11 years old, although she claimed she'd been clean for the previous month, noted a police affidavit.
Eight years later, federal investigators weren't measuring the methamphetamine attributed to Dahl in grams.
They were measuring it in pounds.
A Larger Ring
Dahl's sentencing comes as federal prosecutors continue announcing lengthy prison terms stemming from the months-long 2025 drug investigation.
On Monday, Skavdahl sentenced another Casper man, Gregory Keith McCoy, 56, to 11 years in federal prison, followed by five years of supervised release.
The U.S. Attorney's Office identified McCoy as one of seven people arrested in the Shrove et al. case stemming from the investigation.
McCoy's path into federal court began with a high-speed chase.
Law enforcement tried to stop him near Sinclair on Sept. 24, 2025, after a drug-detection dog was alerted to his vehicle and a passenger exited.
Prosecutors say McCoy took off.
What followed was a pursuit of more than 70 miles that reached speeds of up to 130 mph.
During and after the chase, authorities recovered more than 2 pounds of methamphetamine, along with 67.5 grams of heroin, 13.2 grams of fentanyl pills, less than a gram of LSD and about 50 grams of marijuana.
McCoy pleaded guilty May 19 — the same day Dahl entered her guilty plea.
More Than 27 Pounds
U.S. Attorney Darin Smith said Dahl's sentence shows what federal, state and local agencies can accomplish when they work together against drug trafficking.
“This operation proves that we will not let illegal drugs tear apart our communities,” Smith said. “By working closely with local and state police, we are taking dealers off the streets and protecting Wyoming families.”
DCI, DEA and Homeland Security Investigations investigated Dahl's case with assistance from state and local agencies.
Assistant U.S. Attorney Z. Seth Griswold prosecuted the case.
