A Rockford man will spend 30 years in jail for the murder of his girlfriend.
The Winnebago County State's Attorney says 40-year-old Kurt Knutson pleaded guilty to first degree murder in April.
In October 2012 Knutson told police three or four unknown people beat his girlfriend to death at a park. Later police learned it was Knutson who was responsible for Samantha Therriault's death. Autopsies showed she died from blunt force trauma and strangulation.
Knutson will spend 30 years in jail and then be on supervised release.
