Then around 9.30 to 10 p.m., Draper and Adamczyk claim that they are leaving to go see a movie at a local theater.

Before leaving, Draper secretly, that's what he does.

He secretly unlocks the basement door so that they can reenter later without being noticed.

So while they're in the house, they get a layout of the house, right?

Because she gives them a tour.

And then he secretly unlocks the basement door so that they can come back later.

Then around 9.50 p.m., while away from the house, Draper records a chilling video.

So this video, it's unreal to me.

They're her friend, right?

They recorded her earlier in the day at school.

It actually shows a video of them recording her.

Yeah, like in the hallways.

Like in the hallway getting into her school locker.

And they're like, hey, Cassie.

And they're like joking around with her and stuff.

Then after they leave the house where she's house sitting, they record a video.

Investigators later find that he had been recording footage for a couple of days, taking videos of Cassie at school and showing that he and Adam Chick writing out their plans and describing what they were going to do.

One of the most well-known lines is...

This is from what they were recording of themselves.

The time is nine 50.
