A northwest Iowa man has pleaded guilty on drug charges and may spend the rest of his life in a federal prison. Thirty-year-old Michael Donald Stevens of Royal has admitted he and others made meth in the home where his three children lived. According to court documents, Stevens admits over 50 grams of meth was made in his Clay County home over a three-year period.

This isn’t his first brush with the law. Stevens had a previous meth-related conviction, in Sac County in 2002. He was convicted of delivery of a controlled substance in Buena Vista County in 2003 and again, in early 2005, he was convicted on meth-making charges in Ida County. Stevens faces a sentence of at least 20 years in federal prison, but the judge could sentence him to life behind bars.
