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.

Once the detective got there, we were asked to leave the residence.

They were up in tape around our house and walking around outside.

So obviously, it had turned into a crime scene at that point.

But we still had no idea what had happened to her.

What had happened?

Emma Walker was killed by a gunshot wound to the head from somebody shooting into the house from outside.

Those two bullets fired through the walls of her bedroom, one striking Emma behind her left ear, the second into the pillow by her head.

You know, to hit a target that you can't see, you would have had to know exactly where Emma's head was going to be.

That realization, I think, is a stunning and chilling one.

You talked to her parents.
