Kyron Horman was 7 years old when he was last seen at Northwest Portland’s Skyline Elementary School, on June 4, 2010. The boy’s disappearance prompted what authorities described as the largest search-and-rescue operation in Oregon history, but there have been no arrests made. The Horman case will be covered in a segment on Wednesday’s “In Pursuit With John Walsh,” an Investigation Discovery series that tries to find missing children and fugitives.

As The Oregonian/OregonLive has reported, according to police, “Kyron disappeared from school sometime on June 4, 2010, after his stepmother, Terri Moulton Horman, brought him early to Skyline Elementary School so he could take part in a science fair. He never made it to his second-grade class and was later reported missing when he didn’t return home.”

Since Kyron’s disappearance, his mother, Desiree Young, has made appearances in an effort, as she has said, to try and “help people understand what her family has endured,” and to “help others in similar situations make life livable for relatives and others.”

Walsh’s son, Callahan Walsh, who also works to help find missing children and combat child exploitation, is also involved in the Investigation Discovery series.
