BOISE (AP) — A federal indictment is shedding light on what happened at a remote Montana campsite in 2005 where convicted killer and child molester Joseph Edward Duncan III allegedly videotaped his abuse of two kidnapped children.

The indictment handed up Thursday charges Duncan with 10 felonies, including kidnapping and sexual exploitation of Dylan Groene, 9, resulting in the boy's death. Dylan's sister Shasta, 8, was recovered alive. In a separate case, Duncan also was charged Thursday in California with kidnapping and killing a boy.

A federal judge here Friday entered a plea of not guilty for Duncan, 43, at a hearing in U.S. District Court. Federal prosecutors say they'll ask for the death penalty.
