(CBS/AP) MOUNT PLEASANT, Mich. - A family spokesman says the body of a 4-year-old boy missing in mid-Michigan has been found, a week after his disappearance.
Kevin Chamberlain says Carnel Chamberlain's body was found Thursday, buried under a wood porch at the boy's home.
The boy disappeared on June 21 while in the care of his mother's boyfriend. He was a member of the Saginaw Chippewa Indian Tribe near Mount Pleasant and lived in a house on the reservation, 70 miles north of Lansing.
Searchers from local, state and federal agencies had checked woods, ponds and the tribe's wastewater treatment pools.
Earlier this week, the boy's mother, Jaimee, told local radio station WWJ Newsradio 950 she suspects her boyfriend was involved with Carnel's disappearance.
"I don't know, it just feels like he's hiding something because why wouldn't you just ... take the polygraph test to just help us out with the whole investigation that's going on?" the 21-year-old mother told CBS Detroit.
Officials earlier described the incident as "suspicious," but hadn't labeled anyone as a suspect as of Monday.
Officials say the mother's boyfriend has been "minimally cooperative," according to CBS Detroit.
