(Portland, OR) -- The Multnomah County Sheriff's Office is renewing its search for a boy who disappeared more than a decade ago. The sheriff's office has released a new age-progressed photo of what Kyron Horman might look like today. The office released the photo over the weekend on the 12th anniversary of Horman's disappearance from Skyline School in 2010. Horman was dropped off at school by his step-mother, Terri Moulton, before he went missing. Detectives have not identified a suspect in the case. Horman's mother, Desiree Young urged people to continue searching for her son. A 50-thousand-dollar reward remains for anyone with information that leads to his location.
