A mother of four gone missing, then found murdered.

It's the Karen Swift story, the woman last seen alive at a Halloween party,

and was a second woman also in danger.

And all new 2020 starts right now.

It was a really big deal.

This beautiful, blonde-headed lady comes up missing after a Halloween party.

It was just supposed to be a fun night out.

Adults only.

What's the overall view of this young mom who suddenly goes missing?

People liked Karen. They like being around her.

Tonight, the shocking trial and the ex-wife

you'll only see on 2020.

This is a man I was married to that I shouldn't have been afraid of.

But what about his first wife?

My mom was going out more, which made me start to question why. When they found

Karen's vehicle, it had a badly damaged flat tire. It appears that this group was mainly inserted

into the tire. It was literally screwed into the tire. So this is where you found the smashed cell phones.

In this area here.

Not one, but two smashed phones.

I thought maybe somebody saw her walking and grabbed her.

She doesn't hold back.

I can see Karen going over there and letting him have it.
