A Sanpete County man is accused of killing his fiance and trying to stage her death as a car crash. Anthony Jeffery Christensen was charged with murder yesterday in the death of 34-year-old Kammy Mae Edmunds on March 31st. Investigators believe he made up a story about her crashing a car after a night of drinking, and her dying from her injuries when she came home. They say damage of the car found in a creek bed was not consistent with the death of a person.
