There's something uniquely American about a state fair.

The smell of funnel cakes in the air, the sound of rives rattling overhead.

It's nostalgia and noise all at once, a place built for excess, freedom, and the illusion that nothing bad could happen there.

In September of 1981, the Oklahoma State Fair was in full swing.

Lights stretched across the fairgrounds, midway games stacked high with oversized stuffed animals,

and the sounds of the fair drifted through the night air while families moved through the crowd and teenagers roamed in groups.

It just felt safe.

The kind of place where parents handed their kids a little cash, told them to be smart, and trusted that they'd be home later.

It was a typical Friday night when two teenage girls walked into the fairgrounds together. Shortly after they

arrive, a man approaches them and offers them a job, unloading stuffed animals from a truck.

There are already two boys helping him, so nothing feels unusual about it. Nothing about it

feels dangerous. Plus, it's quick money and easy work. So the girls say yes. They even called home to

tell their families they'd been offered work at the fair, helping to unload the stuffed animals.

They're supposed to call back later to arrange a ride home, but they never do. Their names are Charlotte

Kinsey and Cinda Palette.

They're both 13 years old.

And whatever happened after they left that fair, they have never been seen again.

I'm Sarah Reed, and this is sequestered season four.

The year is 1981.

We're in Oklahoma City, Oklahoma, and this is the disappearance of Charlotte Kinsey and Sinda Palette.

Before the fair, before their phone calls, before anyone knew something was wrong, there were just two girls, Sinda Leanne Pallett and Charlotte June Kinsey, both 13 years old, both from Oklahoma City, both born in 1986, and both at that age where childhood starts to loosen its grip.

When parents begin trusting you a little more, and the world starts to feel bigger.
