Carrie, or the person, the imposter who was pretending to be Carrie, sent Dave about 15,000 email messages over a three-year span.

So I thought, there's got to be a way we can track down this digital activity.

Liz signed up for upwards of 20 or 30 fake addresses that say they're Carrie Farber, and there are different variations on Carrie's name or even her real email address.

Every impersonated message, every text message, there's always a connection back to an account that she has, to a device that she has, or to her house.

She was able to send messages pretending to be Carrie, and they would arrive while she was sitting on the couch next to Dave.

From Dave's point of view, Liz couldn't have sent it because she was sitting next to him the whole time.

It gave a perfect alibi to Liz.

It had a micro SD card in it.

It looked blank.

If you plugged it into your computer, it would look like there was nothing there.

But there was deleted information.

That SD card, it turns out it had been in Liz's phone.

And I wasn't sure what I was looking at first, but it turned out to be a human foot.

What we discovered is that Carrie Farver had that tattoo on her foot.

Liz Golier's charade was over.

Carrie Farver did not voluntarily disappear and drop off the face of the earth.

Very sadly, she was murdered.

It was important for us to clear Carrie's name because she was accused of stalking, she was accused of harassment, and she didn't do any of those things, and that's not who she was.
