ST. CLOUD, Minn. (AP) — A man has been convicted of killing his grandparents at a home he shared with them in central Minnesota.

Thirty-three-year-old Gregory Allen Scheel pleaded guilty in Stearns County District Court to two counts of first-degree murder Thursday.

KNSI reports Scheel cried when he admitted to assaulting and murdering 93-year-old Willie Scheel and 80-year-old Gloria Scheel on March 21st at their Paynesville home.

Scheel put a plastic bag over his grandfather's head and a ligature was used to tie the bag around his neck. He died from asphyxiation. Scheel then wrapped an extension cord around his grandmother's neck and strangled her. He drove the bodies to Kandiyohi County where he lit the car on fire.

Scheel will be sentenced on October 4th.
