FARGO — Ten years ago today, Joseph Edward Duncan III's heinous spree of killing and raping had almost come to an end. At 2 a.m. on July 2, 2005, Duncan — who had lived in Fargo for the previous five years — was spotted with 8-year-old Shasta Groene at a Denny's restaurant in Coeur d'Alene, Idaho. A waitress recognized Duncan as the man wanted for weeks for killing Shasta's family and kidnapping her and her brother. Duncan's dark side hadn't been as easy to recognize during his time in Fargo, despite the former North Dakota State University student being the subject of the city's first-ever sex-offender notification meeting.
