Previously on anatomy of murder.

There was just things that didn't make any sense.

It's like she just damaged off the face of the earth.

Kelsey, we just want you home.

Call us if you can't, and we won't quit looking.

We know she knows something.

I just never expected what she told us to come out of her mouth. I'm Scott Weinberger, investigative journalist and former deputy sheriff.

I'm Aniseika Nikolazia, former New York City homicide prosecutor and host of

investigation discoveries true conviction. And this is anatomy of Mern.

A quick reminder, this is our second episode in a two-part series. If you haven't yet, go back and listen to part one.

Kelsey Bereth was a 29-year-old mother and pilot who had moved to Colorado to be with her fiance

Patrick Frasy. On November 22ndnd of 2018 she had returned to her condo with

groceries and plans to cook a Thanksgiving dinner for Patrick and their young

daughter. But no one had seen or heard from her since.

Trace amounts of blood in Kelsey's condo had investigators fearing the worst.

It really didn't make any sense for her to disappear like that short of foul play.

A big break in the case came when investigators used Patrick's phone records to track down an Idaho nurse named Crystal Lee who made a shocking

confession. She not only knows where Kelsey is, she knows who killed her.

I think everybody's jaws drop.

When she tells us that, yes, Patrick killed Kelsey,

not only that he killed her, how he killed her, what he did was her remains afterwards,

and that he had tried to get Crystal to kill Kelsey on three other occasions.
