Oregon's Cold Case: Kyron Horman Vanishes After Science Fair

The baffling disappearance of 7-year-old Kyron Horman from Skyline Elementary School in Portland, Oregon, on June 4, 2010, continues to be one of the state's most perplexing mysteries. Kyron was last seen at a science fair, captured in a photo beaming next to his project. His mother, Desiree Young, who has relentlessly sought answers for 16 years, described her son as shy but funny. The case initially triggered Oregon's largest criminal and search operation.

Kyron's father, Kaine Horman, had custody at the time and recalled law enforcement's intense focus on the parents, including polygraph tests. His then-wife, Terri Horman, failed multiple polygraphs, fueling suspicion. Allegations later surfaced that Terri attempted to hire someone to kill Kaine, and Kyron's mother suspected Terri's involvement. A civil suit was filed by Kyron's mother to gather information, but it unraveled after a witness invoked the Fifth Amendment extensively.

Terri Horman has consistently maintained her innocence, attributing her failed polygraphs to sleep deprivation and hearing difficulties. She denied involvement in Kyron's disappearance and claims she was made a scapegoat. Despite never being officially named a suspect, public suspicion has lingered. As of May 2026, the Multnomah County Sheriff's Office is utilizing artificial intelligence to analyze digitized case files and explore new leads in the hope of bringing closure to Kyron's family.
