The search continues for a four-year-old boy who went missing from the reservation of the Saginaw Chippewa Tribe of Michigan.

Jaimee Chamberlain, 21, returned home from her job at the tribe's casino on Thursday night to learn that her son, Carnel Chamberlain, wasn't there. She had left him in the care of her boyfriend.

"I ran inside and looked around. I didn't know what to do," Jaimee told the Associated Press.

The tribe has organized searches throughout the reservation. But a press release deemed Carnel's as "suspicious."

The mother's boyfriend is reported to be talking with federal and tribal investigators about the disappearance. No arrests have been made, The Mt. Pleasant Morning Sun reported.
