Ingham County Sheriff's deputies say Ricky is wearing a gray shirt and red pajama pants.
His parents discovered he was missing Saturday morning, when they opened his bedroom door. They found the window open and the bed pushed up against it.
Search teams have been out in Williamston, combing the corn fields, the banks of the Red Cedar River, and even diving in nearby ponds.
Deputies say they would like to speak to Casey Gann. She's his biological mother. She is not a suspect, but Ingham County Sheriff's deputies say they would like to contact her.
