BOISE – If ever a case justified the death penalty, Joseph Duncan’s kidnapping, torture and murder of a 9-year-old Coeur d’Alene boy is the one, federal prosecutors argued Wednesday. A jury of nine men and three women agreed. Duncan committed the crimes after hunting for victims across the region in 2005 and targeting the Groenes, murdering three family members in order to kidnap and molest the family’s two youngest children. One, 8-year-old Shasta, survived.
