The world was a very different place, as was Idaho Falls.

What did it feel like to walk out of prison a free man in 2017?

And so he made up for lost time, got a factory job inspecting potato sacks.

And he got married, which made him both a husband and stepfather to a couple of kids.

Meanwhile, that very spring, the Idaho Falls police kept looking for the man who'd left DNA on the body of Angie Dodge in 1996.

The DNA technology company called Parabon Labs had made this sketch of what that man might look like based on genetic material left at the scene.

And then Parabon made an offer to the new man in charge of the murder investigation, Captain Bill Squires.

Parabon said, hey, you know, by the way, we've got some hours that we have available to commit to this.

Would you be interested in doing that?

And it was easy for me to say, yes, absolutely.

Let's let's do this cooperatively and see where it goes.

No matter the cost, full steam ahead.

And with that kind of priority, Parabon asked the head of its law enforcement unit to join in.

the world's most celebrated genetic genealogist, CeCe Moore, a pioneer in the field, who closed hundreds of cold cases like Angie's.

But this case?

There was a problem.

In fact, when your services were first requested...

Didn't you turn it down?

But then, guess who?

Carol Dodge, Angie's mom, intervened again, begging Cece to get involved and sending her the crime scene photos, which changed everything.
