Case overview

Kyron Horman was last seen at Skyline Elementary School in Portland, Oregon, on the morning of June 4, 2010, after attending a science fair with his stepmother. The seven-year-old never made it to his classroom, and no confirmed sighting of him has emerged in the years since. The case remains open, with investigators focusing on the minutes between his last documented appearance and the moment he was reported missing.

The last confirmed movements

Kyron arrived at Skyline Elementary around 8:00 a.m. on June 4, 2010, accompanied by his stepmother, Terri Horman. The school was hosting a science fair, and Kyron had prepared a project on tree frogs. Witnesses saw him walking through the hallways with Terri, showing her his display. One photo, taken by Terri that morning, shows Kyron standing in front of his project, wearing a black T-shirt with the letters “CSI” in green.

Terri told investigators she left the school around 8:45 a.m., leaving Kyron near his classroom. She said she watched him walk down the hallway toward his second-grade classroom. That was the last confirmed sighting of him by anyone who has come forward.

When Kyron did not get off the school bus that afternoon, his parents assumed he had been marked absent and was with the other parent. By early evening, they realized no one had seen him since morning. The school confirmed Kyron had been marked absent from class. He was reported missing at 3:45 p.m.

The search and initial response

Law enforcement launched an immediate search of the school and surrounding area. Skyline Elementary sits in a rural, heavily wooded area of northwest Portland, near Forest Park. Search teams combed the grounds, nearby trails, and the surrounding forest. Volunteers, search dogs, and helicopters were deployed. No trace of Kyron was found.

Investigators reviewed security footage from the school, but Skyline Elementary had limited camera coverage, and no footage captured Kyron leaving the building. Detectives interviewed students, staff, and parents who had been at the science fair that morning. No one reported seeing Kyron leave the school or encountering anything unusual.

Within days, the Multnomah County Sheriff’s Office classified the case as a criminal investigation. The search expanded, but no physical evidence, clothing, or belongings linked to Kyron were recovered.

The timeline compression

The critical window investigators focused on was narrow. Kyron was last seen around 8:45 a.m. by Terri. His class began at 10:00 a.m., and his absence was noted then. That left just over an hour during which Kyron disappeared.

Terri Horman told investigators she left the school after dropping Kyron off and drove to two different grocery stores before going to the gym. Cell phone records and surveillance footage from some of those locations were analyzed. Investigators have not publicly stated whether those records align completely with her account.

Detectives issued subpoenas for phone records, searched properties, and interviewed Terri multiple times. In June 2010, law enforcement named her as the focus of the investigation, though she was never arrested or charged. Terri has maintained that she left Kyron at school and does not know what happened to him.

The family and the investigation

Kyron’s biological parents, Kaine Horman and Desiree Young, were living separately at the time of his disappearance. Kaine and Terri were married and living together with Kyron and their young daughter. In the weeks following Kyron’s disappearance, Kaine filed for divorce and obtained a restraining order against Terri. He moved out with their daughter. Terri moved out of the family home shortly after.

Kaine and Desiree have both publicly stated their belief that Terri knows what happened to Kyron. Terri has denied involvement and has not been charged with any crime related to the case. In 2012, Desiree and Kaine filed a civil lawsuit against Terri, alleging that she was responsible for Kyron’s disappearance. The lawsuit was later dismissed without a resolution.

Terri’s attorney has argued that law enforcement focused prematurely on her and failed to pursue other leads. No other person of interest has been publicly named.

Leads that went nowhere

Over the years, investigators received thousands of tips. Some led to searches of rural properties, bodies of water, and remote areas in Oregon and Washington. None produced evidence of Kyron.

In 2010, investigators searched Sauvie Island, a large rural area near Portland, multiple times. Divers searched ponds and waterways. Cadaver dogs were used. Nothing was found. Similar searches were conducted in other locations based on tips or investigative theories, all without result.

Detectives also examined whether someone other than Terri could have encountered Kyron at the school that morning. The science fair was open to the public, and the school had numerous visitors. Investigators interviewed attendees and reviewed sign-in logs, but no suspect emerged from those inquiries.

In 2016, the FBI became more actively involved in the case. A task force was formed, and investigators announced they were re-examining evidence using updated technology. No breakthroughs have been publicly announced.

The unresolved question

The case remains open with the Multnomah County Sheriff’s Office. Investigators have stated they continue to follow up on tips and re-examine evidence. Kyron’s parents have continued to advocate publicly for answers.

No arrests have been made. No charges have been filed. Terri Horman has not spoken publicly about the case in recent years. Kaine and Desiree have held annual events on the anniversary of Kyron’s disappearance, urging anyone with information to come forward.

In 2020, on the tenth anniversary of Kyron’s disappearance, law enforcement released a public statement reaffirming their commitment to the case and asking for continued tips. The reward for information leading to Kyron’s location stands at $50,000.

The question of what happened in that brief window of time has never been answered. Kyron Horman was seven years old when he disappeared. He would be in his early twenties today.
