The man accused in the death of a Farley native changed his plea on Thursday.
Twenty-two-year-old Helmon Betwell pleaded guilty to first degree murder. He was sentenced to life in prison with the possibility of parole after entering the new plea.
Police say Betwell attacked and sexually assaulted 66-year old Nancy Krapfl of Dubuque as she was taking an early morning walk in Dubuque on September 1, 2015.
The change in his plea came right before his trial was set to start in Davenport next week.
