He declined to go into detail about the investigation, but reiterated statements from his office that Kyron's disappearance is an isolated incident. Staton said the search has cost Multnomah County about $300,000. Kaine Hormon also moved out Monday and took the couple's 19-month-old child with him. Local and state police, along with the FBI, conducted an exhaustive search for Horman and launched a criminal investigation but have not uncovered any significant information regarding the childs whereabouts. The reason for the restraining order wasn't revealed. A new age progression image of Kyron was released by the National Center for Missing & Exploited Children to show what Kyron would look like at age 14. Kyron Richard Horman is an American boy who disappeared from Skyline Elementary School in Portland, Oregon, on June 4, 2010, after attending a science fair. Kyron's biological father, Kaine Horman, filed for divorce from Terri Horman on Monday, citing 'irreconcilable differences,' and a judge granted his request barring Terri Horman from contact with her children and access to firearms. Investigators haven't named her as a suspect or a person of interest in his disappearance but, points out CBS News Correspondent John Blackstone, 'All the attention (in the probe) has been focused on the former school teacher.' Police have given her two lie detector tests. Terri Horman is the last person known to have seen the second-grader before he vanished June 4. 'She has been cooperative throughout this entire process.'

'To date, there has been no indication that she has been uncooperative,' Staton said.

Staton said he believes Terri Horman is working with investigators. 'We implore (stepmother) Terri Horman to fully cooperate with the investigators to bring Kyron home,' Young said at a news conference at which Terri Horman wasn't present.
