(Portland, OR)  --  Search efforts are continuing in the nearly decade-old case of a missing Portland boy.  Crews searched an area in the West Hills near Northwest Springville Road and Skyline Boulevard yesterday for any signs of Kyron Horman.  Horman was seven-years-old when he disappeared after his stepmother dropped him off at a science fair in 2010.  The Multnomah County Sheriff's Office initiated a search in the West Hills area earlier this month.
