A northern Minnesota couple is due in court this morning (FRI) for the murder and decapitation of a man. 35-year old Joseph Thoreson and 22-year old Kayleene Greniger, both of Grand Rapids, face murder charges after the body of 20-year old David Haiman of Hibbing was found beheaded in June. The woman says Haiman raped her. Prosecutors say Thoresen and Greniger then kidnapped, assaulted and killed Haiman.
