BILLINGS, Mont. — A judge has sentenced a Washington state man to almost 13 years in federal prison after authorities said he trafficked at least 60 pounds of methamphetamine into Montana.

U.S. District Judge Susan Watters sentenced 41-year-old Juan Ramon Delgadillo-Meza of Ephrata, Washington in federal court in Billings on Wednesday.

Delgadillo-Meza was arrested in 2015 when he was pulled over by a Montana trooper and a search revealed a large amount of meth in his vehicle.

Authorities said the defendant, a citizen of Mexico, led a trafficking ring that brought two pounds of the drug into Billings from Washington every two weeks beginning in 2014.

Three co-defendants who acted as Montana-based distributors for Delgadillo-Meza were previously sentenced. They received prison terms ranging from two to almost 13 years.
