Law enforcement will conduct a search Sunday near Northwest Skyline Boulevard related to the 2010 disappearance of Kyron Horman, but a Multnomah County sheriff's spokesman told The Oregonian that investigators have no new information on the disappearance of the boy.

The search is part of ongoing efforts, he said.

"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 was quoted as saying.

Northwest Springville Road is scheduled to be closed Sunday for the search, the newspaper reported.

Seven-year-old Kyron Horman went missing Friday, 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.
