BOISE – Three hundred fifty people will gather in Boise's convention center on Monday to start an extraordinary process: deciding whether Joseph Duncan should die for what he did to two North Idaho children. Available legal records suggest no one's received the death penalty in federal court for a crime committed in Idaho since the 1920s. But Duncan's case is rare in its heinousness and shock value. The convicted killer and child molester attacked a North Idaho family at their home in 2005, killed three family members in order to kidnap two young children, molested both youngsters and held them captive for weeks. Only one child, then-8-year-old Shasta Groene, survived.
