I'm Lester Holt, tonight on Deadline.

The first thing that really got my attention

is wishing one messing, Blood Mountain.

You know, you have to be aware of your surroundings

all the time because just never know.

It's starting with a frightening horror flick from the 80s.

The Crimson movie is we're going to take some women

into the woods and then puff.

They're going to be hunted down.

Decades later, it was happening for real.

A strange vanishing in the forest.

We began to get disturbing news.

Your heart just broke.

Then another.

The tire looked like it had been purposely flattened.

If someone has her, she's afraid.

Do we have a killer running around loose in the National Forest?

Could this old movie hold the key to these new cases?

This film where he's setting women out in the woods.

Do you think that's the template for what he does?

That's what's so chilling.

If anybody could survive, it was Meredith.
