Child killer back in court for competency hearing

 BOISE, Idaho (AP) -- Convicted murderer Joseph Duncan is back in a federal
court in Idaho.
   Duncan was sentenced to death in 2008 after pleading guilty to kidnapping and
 torturing two northern Idaho children before killing one of them in western Montana.
   He is expected to return to U.S. District Court in Boise Tuesday for the first
 of several days of testimony to determine if he was mentally competent when he
 waived his right to appeal his sentence. Duncan's former attorneys argue he wasn’t
 mentally competent to waive the appeal and are fighting his sentence on his
behalf.
   Duncan has been convicted of five different murders in Idaho, Montana and
California. But this competency hearing focuses only on the crimes he committed
against young Dylan Groene and his 8-year-old sister, Shasta, in 2005.
