MOUNT PLEASANT, Mich. (AP) -- Searchers looking for a 4-year-old boy in mid-Michigan have turned the effort to a densely wooded area on an Indian reservation.
Spokeswoman Marcella Hadden of the Saginaw Chippewa Indian Tribe says volunteers and police from the region were looking for Carnell Chamberlain in woods near a medical clinic Saturday.
The FBI has joined the investigation in Mount Pleasant, 70 miles north of Lansing. Hadden says a man who knows Carnell has been approached by authorities but isn't cooperating. He's not in custody.
Carnell, a member of the tribe, was reported missing Thursday night. The tribe says his disappearance is "suspicious."
