Great Falls man sentenced to 12 years in prison for trafficking over 50 pounds of meth

GREAT FALLS - A Great Falls man who had 30 pounds of meth hidden in his home and was pulled over with another 25 pounds of meth in his car was sentenced today to 12 years in prison, followed by five years of supervised release, Acting U.S. Attorney Mark Steger Smith said.

Cody Allen Davidson, 39, pleaded guilty in April 2026 to one count of conspiracy to possess with intent to distribute methamphetamine.

Chief U.S. District Judge Brian M. Morris presided.

The government alleged in court documents that Davidson and his partner, Diane Walters, had been trafficking methamphetamine and that searches of Davidson's home and car turned up bundles of meth, cash, and firearms.

The case began in May 2025 when a source notified the DEA that Davidson had recently received a resupply of methamphetamine that was stored at his Great Falls residence. Using that information, law enforcement obtained a warrant and searched Davidson's home. He was there when officers arrived and agreed to show them "everything," opening up a gun safe that held roughly 30 pounds of meth, four guns and $21,479 in cash. Davidson told authorities the cash was from selling about 7 pounds of meth and that he'd been trafficking it for the last six to eight months.

Two months later, on July 10, 2025, Davidson's car was spotted traveling north of Las Vegas. Law enforcement suspected he was on a drug resupply run and put out an alert for the vehicle. The next day, law enforcement in Idaho Falls, Idaho, spotted the car and pulled it over - Walters was driving and Davidson was the passenger. Hidden in the car, officers found roughly 25 pounds of meth.

Assistant U.S. Attorney Jeff Starnes prosecuted the case. The DEA and Great Falls Police Department conducted the investigation.
