PORTLAND, Ore. – Sunday's search in the West Hills yielded no new information for the investigation into the disappearance of Kyron Horman, the Multnomah County Sheriff's Office said.

Horman disappeared from Skyline School in Northwest Portland on June 4, 2010. Local police, the FBI and hundreds of volunteers scoured the wooded areas around Kyron’s home and his school, but he was never found. He was 7 years old at the time of his disappearance.

No arrests have been made in the case.

Multnomah County Sheriff's Office Lt. Chad Gaidos said there was nothing to update after Sunday's search.

"Yesterday's search yielded a number of items, but none appear to be related to the case," Gaidos said.

Northwest Springville Road was closed from 8 a.m. until 5 p.m. Sunday between Skyline Boulevard and Northwest 128th Avenue for the search.

Volunteers with the search and rescue team combed through thick brush Sunday along Northwest Springville Road.

"The terrain is going to be an issue four our search and team, hence the reason we had to close down the road,” said Multnomah County Sheriff's Office Sergeant Brandon White. “There’s no shoulder, it’s curvy, but also one side is fairly steep going down, so safety is number one for the search and rescue team. It’s a continued investigation. We will continue looking, and doing the best job that we can do."

White said the sheriff's office won't give up on the Horman case.

“The Kyron Horman case is near and dear to our hearts, and it is an open case. Yes, it’s seven years old but still we’re looking at it actively,” he said.

”Being a parent, it’s one of those things. A child has gone missing, and went missing in our neighborhood, and our area. We’re going to do everything we can. We are not going to give up. And we’re going to continue to actively search for Kyron until he’s found.”

Over the past few months, search and rescue crews have quietly conducted searches in connection with the Horman investigation.

“There have been recent searches as recently as March and April. There are going to be more searches in the near future,” Desiree Young, Horman’s mother, said in May.

After a lull in the case, Young feels the pace of the investigation into her son’s disappearance has picked up. New documents from investigators show they’re still actively working the case.

The sheriff’s office said the search is part of the ongoing investigation and no new evidence prompted the search. According to Gaidos, there are no times or dates scheduled for future searches.
