DUBLIN, Va. (AP) _ More than 100 officers are participating in a search for a 5-year-old boy who disappeared from his home in Dublin. Pulaski County Sheriff Jim Davis says Noah Terry Thomas’ mother discovered he was missing on Sunday morning. Davis said Monday at a news conference that there’s no evidence of foul play. He says no one in the area reported seeing anything suspicious. Teams of officers conducted a ground and air grid search on Monday of a 1-mile area surrounding the family’s Dublin home. Bloodhounds also are being used and investigators are canvassing the neighborhood. Davis says the boy’s family is cooperating in the investigation.
