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.

It appeared to be a bullet hole.

At that point, I knew that it probably was not a suicide.

Lead detective Alan Merritt arrives next.

Big hole?

No, it's just a small bullet hole, about the size of a ballpoint ink pen.

But there's no gun inside Emma's bedroom.

Instead, there's a strange discovery on the outside of the house.

And on the far side of the walker's fence, another piece of evidence.

A second shell casing.

So another hole right there.
