Parents of Oregon boy tell Oprah that stepmom involved in son's disappearance

PORTLAND, Ore. - The parents of Kyron Horman have gone on Oprah Winfrey's show to repeat their belief the boy's stepmother was involved in his disappearance three months ago.

Kaine Horman and Desiree Young were on the popular daytime talk show Thursday. They have done a series of interviews and appearances to keep their son’s case in front of the public.

Investigators say Terri Horman was the last person known to have seen the second-grader at his school in Portland. Police have not identified any suspects and no charges have been filed.

Kaine Horman has filed for divorce from Terri Horman and has joined his former wife, Young, in questioning the stepmother’s behavior after the disappearance.

Stephen Houze, the attorney for Terri Horman, would not comment on the show.
