Seven-year-old Kyron Richard Horman disappeared from Skyline Elementary School in Portland, Oregon, on the morning of June 4, 2010. A second-grade student, Kyron was last seen after attending the school’s science fair with his stepmother, Terri Horman. He wore a black T-shirt with CSI in green letters and a handprint graphic, black cargo pants, white socks and black Skechers sneakers with orange trim. He had brown hair, blue eyes, wore glasses, and had a V-shaped strawberry birthmark on his forehead.

Terri Horman said she last saw Kyron walking down the hall toward his classroom at about 8:45 a.m. The last known photograph of Kyron was taken at the science fair; he vanished within the hour. The alarm was raised when Kyron did not get off the school bus at the scheduled stop that afternoon.

Investigation later focused on Terri Horman, who reportedly failed two polygraph examinations. A landscaper told police Terri had offered him money to kill Kaine Horman months before Kyron vanished; Kaine then filed for divorce and a restraining order. Kyron’s mother, Desiree Young, filed a civil suit against Terri in 2012 alleging responsibility for the disappearance, but the suit was dropped. No charges have been filed and Kyron’s whereabouts remain unknown. A $50,000 reward for information remains on offer and investigators continue to review the case files.
