(CBS) PORTLAND, Ore. - The mother of Kyron Horman, a missing Oregon boy who vanished in 2010 at the age of 7, said during a news conference Sunday that a recent search for her son was "successful" after multiple items were found, CBS affiliate KOIN reports.
"If he was here, he would say thank you very much," Desiree Young said of her son.
She said information gathered during the weekend volunteer-led search would be turned over to law enforcement.
The search, which took place in Portland and retraced an area searched shortly after Kyron's disappearance, was led by the volunteer group Kryon Horman's World Soldiers and two non-profit search organizations. The search was also reportedly aided by 10 search dog teams.
Young said multiple items recovered in the efforts have been turned over to the Multnomah County Sheriff's Office, which she praised for its continuing efforts in the case, KOIN reports.
Young has refrained from naming exactly what was found, citing the "continuing investigation."
But, she said, "We will find him."
Kyron was 7-years-old when he vanished from Skyline School on June 4, 2010. His disappearance prompted the largest search in Oregon's history, but he was never found.
No suspects have been named in the case, but the investigation centered on the boy's stepmother, Terri Horman.
"I refuse, refuse to let Terri win," Young said Sunday.
According to KOIN, Terri Horman was one of the last people known to have seen Kyron alive. Authorities have stressed she has not been charged with a crime related to the boy's disappearance.
Following the news conference Sunday, Lt. Steve Alexander with the Multnomah County Sheriff's Office confirmed some items recovered in the search had been turned over to the sheriff's office. He said the sheriff's office does not know whether the items are significant to the case and cannot officially call the items evidence at this time, the station reports.
