(Portland, OR) -- It doesn't appear there are any new breakthroughs in the case of a child who went missing in Portland seven years ago. Law enforcement officials conducted a search yesterday for clues in the disappearance of Kyron Horman. Horman disappeared June 4th of 2010 and although the largest search and rescue operation in Oregon was conducted, tips continue to come in from all across the nation. The search closed Northwest Springville Road from 8:00 a.m to 5:00 p.m between Northwest Skyline Boulevard and Northwest 128th Avenue. No arrests have been made in the case.
