Two Great Falls brothers have been sentenced to federal prison for their roles in distributing methamphetamine and taking stolen vehicles to Spokane, Wash., as part of a drug trafficking operation.

The U.S. attorney's office says 47-year-old Daniel Wakeford was sentenced to 10 years in prison while 48-year-old Michael Wakeford was sentenced to 10 years and four months. They were sentenced by U.S. District Judge Sam Haddon on May 9.

Prosecutors said police were investigating a group suspected of bringing meth from Spokane, Wash., in April 2010. By that summer, officers also learned the group was transporting stolen vehicles from Great Falls to Spokane as part of the trafficking operation. The Wakefords were charged with stealing four motorcycles in August 2010 as well as bringing drugs back to Great Falls.
