A Paynesville man has pleaded guilty to two counts of first-degree murder in the death of his grandparents. Stearns County prosecutors say 34-year-old Gregory Scheel will receive consecutive life sentences and could be eligible for parole in 60 years. Investigators say 93-year-old Willie Scheel was suffocated with a plastic bag put over his head and 80-year-old Gloria Scheel was strangled with an electrical cord. The grandparents’ bodies were found March 22nd inside their partly-charred vehicle on a rural road in Kandiyohi County.
