Even though Kyron Horman has been missing for nearly two months, his biological mother is convinced he is still alive -- and that stepmother Terri Horman knows where he is.
"I believe that he’s stashed," Desiree Young told PEOPLE magazine on Tuesday. "I believe it's the investigation that's going to lead us."
She believes Terri planned the abduction for some reason. Terri has, according to Young, "the big answer."
Kyron's father Kaine agrees with his ex-wife's contentions about his estranged wife.
"I think it [was] arranged," adds Kaine. "We have no information that would lead us to believe that, but I think based on what Desiree and I know about [Terri], I think it's a plan. And I think she's still executing a plan."
He also predicts a happy ending to this saga. "Someone is going to spot him. We're going to get him," Kaine said, adding that he and Young have been stressed and frustrated because "it shouldn't have to take a while. It should be done by now."
