Update: Saturday 11:30 a.m.

A Multnomah County sheriff's spokesman said investigators have no new information on the disappearance of Kyron Horman. The search is part of ongoing efforts.

"This is a case very near and dear to our hearts and any chance we can get out with search and rescue teams, we do that," Sgt. Brandon White said.

Law enforcement on Sunday will conduct a search near Northwest Skyline Boulevard related to the 2010 disappearance of Kyron Horman, a Multnomah County sheriff's spokesman confirmed late Friday afternoon.

The spokesman said Northwest Springville Road is scheduled to be closed Sunday for the search. He said he did not know of any new information or evidence that prompted the search, which is "ongoing," he said.

The 7-year-old Horman disappeared on June 4, 2010, from Skyline Elementary School in Northwest Portland. Investigators conducted the largest search and rescue operation ever in the state, but they found no sign of him.

No arrests were made in the case.

Springville will be closed from 8 a.m. to 5 p.m. between Northwest Skyline Boulevard and Northwest 128th Avenue, Multnomah County officials said in a news release.

The area is about five miles from Skyline Elementary School.
