A Mason City man has pleaded guilty in a "smurfing" case.

Twenty-nine-year-old Adam James Rollins of Mason City was accused of smurfing — working with a crew who went from store to store in Iowa and Minnesota to buy large quantities of medications. The medications contained pseudoephedrine which is a main ingredient for methamphetamine.

Prosecutors say Rollins gave the pills to other meth-makers and sometimes used the pills to make meth himself. He’s pleaded guilty to one count of conspiring to manufacture methamphetamine.

Rollins could be sentenced to as little as 10 years in a federal prison, or the judge could sentence him to serve the rest of his life behind bars.
