PORTLAND, Ore. -- May 25 is recognized each year as National Missing Children’s Day. This year, the FBI’s Portland division shared three long-term investigations involving Oregon kids on their Twitter page.

One of those cases is the disappearance of Kyron Horman. Horman was 7 years old and last seen at Skyline Elementary School in Portland on June 4, 2010. He has never been found but investigators say the case is active and ongoing.

A KGW investigation in 2017 revealed that the Multnomah County Sheriff's Office was coordinating ground searches and detectives were analyzing new computer evidence. A grand jury continues to hear evidence in Kyron's disappearance and has met multiple times.
