(Undated) — A Hutchinson woman has pleaded guilty to obstructing an investigation in connection with the August 2014 murder of an Annandale man. 33-year-old Gwen Butcher was accused of aiding Robert Nuttall in the death of Christopher Rossing. Investigators believe Butcher helped load Rossing into her vehicle after he fought with Nuttall in Howard Lake. Butcher then drove both men out to her home southwest of Hutchinson. That was the last time Rossing was seen alive. Nuttall pleaded guilty to murder in November and was sentenced to 20 years in prison. Butcher’s sentencing is set for January 28th.
