The parents of missing Oregon boy Kyron Horman appeared on "The Oprah Winfrey Show" on Thursday, saying they are convinced Kyron is still alive, and he is being held captive somewhere.
Kaine Horman and Desiree Young said they are also convinced of something else -- that Kyron's stepmother and Horman's estranged wife Terri is involved in his disappearance.
"Ever since Kyron went missing, there has been so many things that we've found out and added up and all of it -- red flags," Young said.
The first red flag was when Horman said his wife told him she had failed a polygraph test, and she kept changing her story about what happened that morning after she dropped Kyron off at school.
"She would change her story daily, if not more than that," Horman said. " I mean, every time you talked to her, it was a little bit different."
The interview comes a day after the Multnomah County Sheriff's Office announced it was shifting its strategy. With costs topping $1 million, the investigation will now be a taskforce of 8 to 10 detectives, compared with as many as 25 officers.
Multnomah County Sheriff Dan Staton said the changing strategy does not mean police are giving up or this is now a cold case.
"I don't want the family to believe we are changing this investigation in any way, shape or form ... I think all the investigators involved believe there is going to be an outcome in this," Staton said.
Staton also echoed what the parents said on "Oprah," that so far he has seen no evidence that indicated that Kyron is not alive. He said there had been "significant movements" in the 15-week investigation.
When asked if people would be shocked to find out what they know, Staton took a long silence.
"I know I'm taking a long pause on that, I have to think through that answer. I think there are things that come out of this investigation that will surprise you, that you'll think about later on when it's over. We have a knowledge of things we don't want to know about ... of things we wish we didn't know," he added.
