MINNEAPOLIS — An Eden Prairie man has been sentenced to 61 years in prison for killing with parents with a screwdriver.

Nathan Lehman, 38,was sentenced Monday after earlier pleading guilty to two counts of second-degree murder. He was charged in the deaths of Robert and Debra Lehman of Eden Prairie last May.

Prosecutors say Lehman has a history of mental illness and methamphetamine addiction and wasn’t following orders of his mental health caseworkers.
