A Lincoln man has been sentenced to more than 15 years in prison for helping distribute more than three pounds of methamphetamine.

U.S. Attorney Deborah Gilg says 29-year-old Kenneth Caldwell was sentenced Tuesday to 15 years and 8 months in federal prison.

Authorities say Caldwell helped distribute the drug in the Lincoln area between January 2010 and September, 2012.

Caldwell was also ordered to serve five years on supervised release after he gets out of prison.
