Unsolved: Kyron Horman

So we're going to head 16 miles northwest of Portland, Oregon in 2010, near the towns of Fulkenberg and Burlington.

It's driving distance to Portland, but it's still a very rural area.

You've got mountains on one side, farms, marshlands, thousands of acres of forest on the other.

It sounds like this very beautiful, peaceful place.

But in 2010, that peace was shattered pretty much for good when a seven-year-old boy named Kyron Horman went missing.

So seven-year-old Kyron Horman woke up on the morning of June 4th, 2010,

excited about his second grade science fair project, which was all about the life cycle of red-eyed tree

frogs.

It was very adorable.

That day was also Parents' Day, where everyone was invited to school to see these kids' projects.

So Kyron's father, Kane, has to miss it because he has work that day.

But before he left that morning around 745, he told Kyron how proud he was of him and that his wife, which is Kyron's stepmom named Terry, was going to be there instead.

So around 8 a.m., Terry strapped their 19-month-old daughter, Kiara, into her car seat and Kyron hops in the backseat with her.

Terry then drove Kane's white Ford F-250 pickup truck instead of her usual red Mustang because she said that she thought it was going to be easier to transport Kyron's project in that car.

And they arrived at Skyline K-8 school before 8.15 a.m., And the place was in complete chaos, as you can maybe imagine.

It was packed with over 400 visitors.

You have all the kids, you have all their parents, grandparents, siblings.

They're all there to see these kids' projects.

Kyron dropped off his backpack and he hung up his jacket in his classroom before he went and showed his project to everyone.

Then Terry, Kiara and Kyron wandered through various classrooms, checking on the other kids projects that brought them in.

And they arrived at Kyron's class where Terry snaps this photo of Kyron standing proudly next to his diorama.

He has this huge gap tooth grin.

He has his little glasses on and he's wearing his crime scene investigation shirt because he was obsessed with CSI and being a detective.

And around 845 in the morning, Terry says goodbye to Kyron.

She says that the two of them went up different stairwells and she watched as Kyron walked down the hallway towards his classroom.
