Search on for Boy Last Seen at Oregon School

PORTLAND, Ore. -- The search continues for a 7-year-old boy last seen walking towards his classroom at a Portland, Ore., school Friday morning.

The Multnomah County Sheriff's Office searched overnight for second-grader Kyron Horman in the area around Skyline Elementary School in northwest Portland.

Several agencies, including the Federal Bureau of Investigation, have joined the search.

Sheriff's spokeswoman Lt. Mary Lindstrand says the boy's stepmother reported last seeing him walk down the hallway towards his classroom at 8:45 a.m. Friday. School staff didn't see him after that time and report that he didn't make it to class.

Police were called Friday afternoon when the boy didn't come home from school on the bus.
