Feb. 20, 2011— -- Kyron Horman's mother said today she has begun to put new pressure on the missing Oregon boy's stepmother with a clear message: She will not stop until Terri Horman is "brought to justice."
Desiree Young spoke with "Good Morning America" today from Roseburg, Ore., the town 200 miles from where Kyron was last seen and the new home of Kyron's stepmother, Terri Horman.
Kyron Horman disappeared the morning of June 4, after participating in an early morning science fair at his suburban Portland elementary school. Police said he was last seen walking down a hall at the school with his stepmother.
"Kyron's story is not one of a child that wandered away from his school or was abducted by a stranger," Young said Saturday at a news conference in Roseburg. "It was somebody who was brought into our family. ... There is one person that knows where he is: Terri Horman, where is Kyron?"
On "Good Morning America" today, Young said she has gone to Roseburg to distribute flyers urging people in the small town to keep asking that question of Terri Horman, the last person known to see Kyron.
"I believe that it was important to raise awareness in Roseburg, [where] people are not aware of who I am, who Kyron is, let alone Terri, who lives here," Young said.
"It was concerning, because we have knowledge that she's handing out Halloween candy to children, she's going into bars, and enjoying the holidays with her family -- all while Kyron is not here. We thought it was time to step it up a notch," she said.
Young also said investigators presented her with new evidence that she said raises questions about Terri Horman's character.
"[The evidence] indicated that not only could Terri be capable of this, but it was clear that she hated Kyron, and blamed everything on Kyron -- and had expressed that on various occasions to friends and people that she knew," she said this morning.
Phone calls to Terri Horman and her attorney from ABC affiliate KATU-TV in Portland about Young's efforts and her new claims were not returned Saturday.
Young indicated that the people of Roseburg have been very supportive of her efforts to create awareness of the investigation and the search for her 8-year-old son, thanking them on air. But her direct statement to the boy's stepmother stayed on point.
"To Terri I have a different message -- I will be here each and every day to remind you of what you've done, remind you of Kyron, and make sure that you are brought to justice," she said firmly.
Bruce McCain, the former captain of Multnomah County Sheriff's Department, which spearheaded the search for the boy, told "GMA" it is a sad sign of the difficulty of the case that Young felt she had to escalate her efforts to find out what happened to her son.
"This is by far the most dramatic step she's taken," McCain said. "But the fact that a biological mother now has to take matters into her own hands again is a reflection on the status of the investigation.
"There is no bloody foot prints, no torn 'CSI' shirt, no broken eyeglasses -- so this investigation really has had a severe lack of physical evidence from the very beginning," he added.
Police are expected to make an announcement in the case later this week, but Young indicated it will most likely be a plea for more help in the case and money for the Kyron Horman Task Force.
Kyron's father, along with Young and the police, have all pointed fingers at Horman, but she has not been charged or even named a person of interest.
She was previously the target of strong words from Young during an interview with "Good Morning America" in late August.
"You will go to jail, and whoever has been helping you, if they don't talk, they will go to jail," Young said. "I really believe that you want to do the right thing here and bring Kyron home."
Kaine Horman has since filed for divorce, after being told that Terri Horman had allegedly tried to hire someone to kill him. Police have indicated that there are discrepancies in Terri Horman's account of what happened on the morning of June 4.
Terri Horman has remained steadfastly silent through most of the investigation, only releasing brief statements through her attorney that she did not have anything to do with Kyron's disappearance.
Terri Horman's lawyer, Stephen Houze, has said that his client had received death threats and that the media frenzy surrounding the case had morphed into a "witch hunt."
Kaine Horman and Young have said they believe DeDe Spicher, a friend of Terri Horman, aided her in the disappearance of Kyron.
In July police doubled a reward to $50,000 for information that leads them to finding Kyron. They had previously received 3,500 leads and thousands of tips, according to Capt. Monty Reiser.
