Lester Holt

You see people mentioning this murder on social media.

Allison had already told you about it.

So you're reading about it, and then she's told you her story.

How are things adding up to you?

What James saw contradicted what Allison had been telling him about her relationship with Delbert.

She's telling you that she only got involved with him after his wife died.

Kate's background in criminology drove her to build a timeline.

I ended up going back and looking up the dates of her marriage.

And with it being within 90 days of his wife dying, you know, she had a hand in it.

You believe that?

Firmly.

It was quite a leap from con artist to potential killer.

Investigators back in Texas could never prove it.

But for Kate and James, what happened next made their suspicions hard to ignore.

She surprises you with a big ask.

James Turrentine believed Allison Salinas was a con artist, and he wondered if his high school ex was more involved in that murder down in Texas than she let on.

Did you confront her with that at all?

Why not?

James has Allison texted and called him relentlessly for months.

A lot of the discussion was about her husband, Patrick.
