BUFFALO (AP) - A Hutchinson man has been sentenced to 20 years in prison in the death of a man whose fragmentary remains were found in a fire pit last fall.

Twenty-nine-year-old Robert Nuttall earlier pleaded guilty to felony unintentional murder in the death of Christopher Rossing just as his trial was about to begin in Wright County.

A criminal complaint says Nuttall beat the 25-year-old man unconscious during an argument over a woman in August 2014 after a night of drinking.

Sheriff's officials executed a search warrant at Nutall's Hutchinson farm in October and found bone fragments and teeth in a fire pit. Dental records later confirmed the remains belonged to Rossing.
