A Las Vegas mom who decapitated the father of her children and threw his head in the trash claimed she "only wanted to hurt him" so she could be with her kids. On Wednesday, Devyn Michaels, 46, pleaded guilty to second-degree murder in connection with the beheading of her ex, 46-year-old Johnathon Willette at the Henderson, Nevada home he shared with his mother, in August 2023, according to KLAS-TV.
