PORTLAND, Ore. -- The mother of a Portland boy who disappeared four years ago says the search for her son will extend to a new area this weekend.
Desiree Young said the search could aid authorities in the investigation during an interview Friday morning on KATU News.
"We have some information that this area can be key in the investigation, so we're going to try and help law enforcement," Young said. "Sometimes it's just us ruling out areas. It depends. And other times it's where we're searching an area that's key to the investigation."
Kyron Horman vanished from Skyline Elementary School on June 4, 2010, after his stepmother, Terri Horman, brought him there early that day to attend a science fair. The 7-year-old boy never made it to his regular class. He was reported missing later that afternoon when he didn't return home on the school bus.
A massive search came up empty, and no arrests have been made. Investigators have long focused on Terri Horman, although they have not named her as a suspect.
