DURANGO, Colo. (AP) -- A Mexican national has been sentenced to 10 years in prison for running a multistate methamphetamine operation out of southwest Colorado.

Sergio Molinares Macias was sentenced Thursday by District Judge Jeffrey Wilson in Durango.

Prosecutors said Macias' La Plata County operation distributed methamphetamine in Arizona, Colorado, Utah, Oregon, New Mexico and Idaho. Undercover police working with the U.S. Drug Enforcement Administration bought a half-pound of methamphetamine from the ring before arresting the 23-year-old Macias.

Macias had pleaded guilty Sept. 24 to felony distribution of methamphetamine.
