The search is continuing for a 4-year-old mid-Michigan boy missing since Thursday night.
Saginaw Chippewa Indian Tribe spokeswoman Marcella Hadden says Sunday that police cadaver dogs have joined in the search near Mount Pleasant, about 70 miles north Lansing.
The boy is a member of the tribe and was reported missing by his family around 10 p.m. Thursday. Firefighters, police and volunteers have been searching on an around the Saginaw Chippewa Indian Tribe reservation where he last was seen. The FBI joined the search this weekend.
Two search and rescue teams and more than 100 volunteers were scouring a dense wooded area just off the reservation Sunday afternoon.
Hadden says the boyfriend of the boy's mother initially had not been cooperating with authorities, but was being "minimally cooperative" Sunday.
