It’s been 13 years since seven-year-old Kyron Horman vanished, shortly after showing off his science project at his school in northwest Portland, Oregon.

His case captured the attention of people around the globe, resulting in a documentary and even a book by a New York Times best-selling author. But Kyron remains missing and his mother is still hoping to bring him home.

On June 4, 2010, Kyron left for school with his stepmother, Terri Horman, looking forward to showing off his second-grade science project on tree frogs.

The pair took Kyron’s father, Kaine Horman’s, truck to Skyline School that day. Terri didn’t normally drive the car but said she’d need it to bring Kyron’s science project back home.
