I'm Lester Holt, tonight on Deadline.

A young mother vanishes and disturbing secrets come to light.

She was free-spirited.

She just loved life.

What were the chances she would ever walk away from that family?

There weren't any chances.

Liz would have never left her children.

The missing persons unit did not see any signs of foul play.

I was like, look, you know, I know I'm just a friend.

I just feel that something's wrong.

I very, very, very much believed that my friend was in danger.

Did you get the impression that you were on a list of possible?

Definitely.

Her husband, he was under suspicion basically immediately.

There were searches of his home.

The husband was cooperative.

The boyfriend was not.

He got a warrant for his home, his phone, his computer.

This was a very complicated case.

Elizabeth mattered.

She needed to get justice.

I had gotten a call saying, you'll never believe this.
