On a spring morning in 1996, a young woman named Angie Dodge doesn't show up to work.

Hours later, police rushed to her apartment and discover a bloody crime scene.

It was an absolutely savage murder.

It was probably the worst case I've ever seen.

Angie was just 18 years old.

News of her brutal killing quickly spreads around Idaho

Falls. That was our friend. Somebody took her away from us. We're getting this because he's still out there

whoever it is. As detectives try to figure out who's responsible for Angie's violent death, they zero in on a suspect.

I don't know what the hell you guys want.

You'd think we'd be wasting our time and wasting your time if we didn't think you're involved, here?

But do they have the right man?

It's a puzzle that spirals into a decades-long nightmare.

I mean, you have a child that's murder.

Life just gets shattered.

A puzzle that isn't solved until Angie's mother

helps put the pieces together.

Twenty-three years I've been trying to put this puzzle together,

and the center's missing.

This is a case that turns friends into enemies and back again.

It took away 20 years of my life.

I've always been told the truth will come out.

You can't hide the truth.
