PORTLAND -- The mother and father of missing Portland seven-year-old Kyron Horman are once again pleading for help to find him, and answered questions from reporters Friday morning.
Desiree Young said she had "a feeling" Kyron was "stashed" somewhere, reiterating the theory she outlined to People magazine earlier in the week.
"Eight weeks is a hard marker to hit," she said in reference to his disappearance from Skyline Elementary on June 4. "My theory is that Kyron's alive and someone's holding him. We don't know how many, we don't know who," she said. "We don't have any evidence to show that he's not (alive.) That's a big deal."
Kaine Horman said they felt investigators were going down all the right avenues, despite no suspects or persons of interest having yet been named.
But attention has focused on Kyron's step-mom, Terri Moulton-Horman. She was the last person to report seeing Kyron after dropping him off. Detectives had not interviewed her since she retained high profile criminal defense attorney Stephen Houze in July.
"If an arrest happens, they're going to have their ducks in a row," Desiree said in regards to the investigation.
The couple pleaded with anyone who knows Terri, her friends or Kyron to come forward.
"If you have any information, even if it's insignificant, please bring it forward," Kaine said.
In court documents, the boy's father Kaine Horman stated police had provided him with "probable cause" to believe that Terri was involved in Kyron's disappearance, plotted to have Kaine killed, and was having a sexual affair.
Kaine said he pleaded with Terri daily to give investigators any information that could help before taking out a restraining order.
"Surprisingly cold," was her reaction, Desiree said. The two said they believed there was no question as to Terri being involved.
Desiree told People Magazine this week she thinks someone is holding him alive. Desiree and Kaine Horman made several appearances this past week from the sheriff's news conference to a Dateline NBC special.

The reward for information that leads to missing Portland seven-year-old Kyron Horman was doubled Tuesday from $25,000 to $50,000 by an anonymous donor.
Kaine said he was not aware Terrie had any links to people involved in any possible criminal activity.
Multnomah County Chief Deputy Tim Moore and Captain Monte Reiser appeared with Desiree, father Kaine and step-father Tony Young and delivered prepared statements Tuesday. No questions from reporters were allowed.

"We believe that Kyron’s disappearance involves criminal behavior because we have (the) parents that have been deprived of their son for 53 days," Moore said.
Investigators said they'd made "significant progress" in the investigation, and reaffirmed their belief that Kyron's disappearance involved "criminal behavior." Investigators said 11,000 man-hours had already been put into the case and 3,500 tips had been received since the boy disappeared, in what has become the largest search effort in Oregon's history.
Speaking for the family, Desiree Young said they remained confident in law enforcements' efforts to bring Kyron home and to bring to justice to whomever was involved in his disappearance.
The two said since there was such a large gap in time before anyone knew he was missing, he could be anywhere in the world, and that's why they are continuing to talk to national media.
"Every stone that needs to be unturned, I don't care what state it's in, we've got to look," he said.
"We love you Kyron, never give up hope," a choked up Desiree Young said from the Multnomah County Sheriff's office at a briefing on Tuesday. "We are all coming to get you to bring you home."
At Tuesday's press conference, Moore reiterated that authorities believe Kyron's disappearance involved criminal behavior, and that they were not aware of any similar case in the Northwest.
Last week, police searched the homes of three friends of Terri's to look for evidence. One of those friends was identified by Kyron's parents as DeDe Spicher. Reliable sources said police think Spicher has information about Terri's whereabouts on the day Kyron disappeared. More: Who is DeDe Spicher?
A statement from Kaine and Kyron's mother Desiree Young also said Spicher is not cooperating with the investigation, but she appeared before a grand jury after a subpoena Monday and her attorney said she would continue to cooperate. More: Spicher appears before grand jury
Earlier this month Kaine had Terri evicted from the family's NW Portland home and he returned to the home with Kiara.
