The next day, she's home alone.

She's taunted at home by someone dressed in black banging on her door.

You know, that is rattling.

In two days of this now, had to have been wearing her down.

The next day...

I went in there to wake her up, which is usually very easy to wake her up, and said her name, didn't hear anything, bumped her leg, didn't hear anything, and then went to her face and realized and checked for a pulse and couldn't find anything.

I don't remember a whole lot from that moment.

I mean, I know I called 911.

Emma's mother makes maybe one of the most heartbreaking 911 calls that I've ever heard.

and you hear in real time this mother's sort of

visceral response to realizing that, like, maybe she's not gonna be okay.

The call came out as a suicide.

It was about 30 minutes before shift was over.

Officer Nikki Buhls is sent to the crime scene.

She's now the lead forensic tech on the case.

When I first got there, I started my photographs on the outside of the residence.

I walked in, photographed the interior of the residence, photographed the bedroom.

It's a classic teen girl's bedroom.

A little messy, clothes and makeup all over, pictures and cheer trophies on the wall.

Except... There was a hole in the wall.
