Kyron Richard Horman (born September 9, 2002) is an American boy who disappeared from Skyline Elementary School in Portland, Oregon, on June 4, 2010, after attending a science fair.

[3] On June 4, 2010, Kyron was taken to Skyline Elementary School by his stepmother Terri Horman (Moulton),[5] who then stayed with him while he attended a science fair.

Terri's statements to the police indicate that, after leaving the school at 8:45 a.m., she ran errands at two different Fred Meyer grocery stores until about 10:10 a.m.[8] Between then and 11:39 a.m., she stated that she was driving her daughter around town in an attempt to use the motion of the vehicle to soothe the toddler's earache.

Terri said that she then went to a local gym and exercised until about 12:40 p.m. By 1:21 p.m., she had arrived home and posted photos of Kyron at the science fair on Facebook.

[12] In late June 2010, in the midst of the search, Kaine was reportedly told by investigators that Terri had offered their landscaper, Rodolfo Sanchez, "a lot of money" to kill her husband.

[13] Investigators convinced Sanchez to confront Terri while wearing an audio surveillance device, but they were unable to obtain any evidence and could not make an arrest.

[18] In August 2010, it was announced that law enforcement were searching for an individual allegedly seen by two witnesses sitting inside Terri's truck outside Skyline Elementary the day of the disappearance.

"[20] According to law enforcement, Spicher was "extremely cooperative" and allowed a search of her property and car, as well as enduring three hours of questioning from detectives.

"[23] In early August 2010, Young, Kaine and the Skyline Elementary School principal were subpoenaed and testified during the grand jury hearing.

[26] By November 29, 2010, search efforts in Kyron's case had cost an estimated $1.4 million, according to county commissioners, and yielded 4,257 tips.

[26] In May 2017, it was reported by Portland station KGW that a secret grand jury panel continued to hear evidence in Kyron's disappearance, and had convened on multiple occasions.

"[34] She denied having any involvement in Kyron's disappearance, and also stated her belief that he was kidnapped, adding: "There was a man in a white pickup truck, Ford, parked on Highway 30 at the 7-Eleven, which is not near the school.

[35] "Vanished from School," season 2, episode 2, of the television show Real Life Nightmare on Discovery ID explores the case.
