And police are testing remains that might be Dylan's.
But much of what happened to the children in the seven weeks since they were abducted from their home has been a mystery.
Security camera videotape showed Shasta Groene and her alleged kidnapper at the store Friday evening in Kellogg, about 40 road miles east of Coeur d'Alene. Shasta seems to look into the faces of other customers but no one identifies the girl who's been missing for nearly seven weeks.
"It's a little sad to see her actually walk around and look at people and then people not recognize her," Kootenai sheriff's captain Ben Wollifinger told CBS News.
In the surveillance video, Shasta asks no one for help. But child trauma expert Dr. Lenore Terr says her body language is a painful scream. Her arms are held tight to her chest, her eyes fearful.
"They're been terrified by this person, they've been probably physically hurt by this person; they may have witnesses horrible things happening to others at the hands of this person,'' Terr said.
Court papers released publicly on Tuesday night said Shasta told authorities her captor repeatedly molested her and her 9-year-old brother. Although it is not CBS News policy to name victims of sexual assault, the Idaho children's names were widely disseminated before the new allegations.
Cameron Conoco owner Ted Beamis told The Associated Press that the girl's alleged abductor, Joseph Edward Duncan III, "acted like he didn't have a care in the world.
"He was walking around. You could see him kind of watching her. One time in the store she's wandering up and down the aisles, and he kind of loses track of her, and you can see him looking around in a panic."
