Did you hear that?

I'm trying to call the other roommates.

They're not answering.

You've got somebody who had been drinking, was in and out of slumber, and somebody walks through in the middle of the night and still wonders in her own mind, did she see it or did she dream it?

She makes a mad dash for Bethany's room and decides to run downstairs and spend the rest of the night with Bethany.

As night turns into day, everything in Moscow is still quiet.

But investigators say that Brian Koberger is awake.

He's active.

That includes spending more than an hour and a half on the phone with his mom and posing for a selfie, giving a thumbs up.

Police say just after 9 a.m., Coburger is on the move and he's headed back to 1122 King Road.

He's not seeing anything on the news.

I think he certainly would expect this is going to be everywhere immediately.

So I think that his curiosity has absolutely gotten to him.

And so he goes back to the area.

But for all of his training, for all of his things that he studied, crime scene and serial killers, PhD program for criminology, he made an absolutely critical mistake in that house that night.

I woke up in the morning, just kind of like chill Sunday.

Emily and Hunter came and were hanging out in my bed with me.

And then Dylan called Emily and asked us all to come over.

I could overhear what was going on.

She sounded freaked out.
