Their focus has shifted to finding a nine-year-old boy who has been missing for six weeks.
Idaho authorities hope to gain information from the boy's eight-year-old sister. Shasta Groene (GROH'-nee) was recovered from registered sex offender Joseph Duncan Saturday. She's said to be "resting comfortably" at a hospital.
Kootenai County Sheriff's Captain Ben Wolfinger says her brother Dylan is presumed dead, but officials want to find him "one way or another."
Wolfinger says investigators have talked with the girl, but it's a "slow process" getting information from her, because she's been through so much.
Authorities found the children's mother, brother and the mother's boyfriend beaten to death in a house in mid-May.
