BOISE – Jurors frowned, pursed their lips, some reddened visibly and one gasped out loud as U.S. Attorney Tom Moss detailed the horrific tale of Joseph Duncan’s crimes, intricately planned in advance, culminating in the sexual torture and murder of a 9-year-old boy and an attempt to burn beyond recognition every piece of his body. Federal prosecutors will call 90 witnesses over the coming weeks to show why Duncan should die for his 2005 crimes. Those witnesses, however, won’t include Duncan’s only surviving victim, 11-year-old Shasta Groene. Instead, Duncan and prosecutors filed an agreement with the court late Wednesday waiving Duncan’s right to cross-examine the girl and allowing two videotaped and four audiotaped interviews she gave to law enforcement officers after her rescue to serve as her testimony.
