COEUR D'ALENE, Idaho -- A convicted serial killer has returned to Idaho.
Joseph Duncan is in Ada Co. Jail awaiting a competency hearing.
A judge will decide if Duncan was competent when he gave up his right to appeal his death sentence.
Duncan got the death penalty for the 2008 kidnapping of Dylan and Shasta Groene from the Coeur d'Alene area. Police say he tortured them, and then killed Dylan.
Duncan is due in court Tuesday morning.
