Police are asking the public for tips about Sky's disappearance and are offering a reward up to $1,000 for helpful information.
"We have been challenged to try to find evidence and facts to support Julia's story," Johnson said. "We want to believe Julia, we want to help her find her missing child, and we want her cooperation to do that. And at this point, the information she has given us has been problematic and has created more questions than answers."
Sky is half Indian and half Caucasian, with brown eyes and dark buzz-cut hair. He was last seen wearing a dark green hooded sweatshirt with blue and gray striped Carter's pants.
Anyone who sees a child matching this description is asked to call 911 immediately.
