 A Red Wing man is confessing to killing his infant son. Hunter McCutcheon agreed yesterday to plead guilty to second-degree murder in connection to the baby's death in May of last year. The plea deal calls for first-degree murder and other lesser charges to be dropped and for McCutcheon to receive a 40-year prison term. An X-ray of the baby's chest showed broken ribs and a broken collarbone. McCutcheon later admitted to hurting the infant.
