Christopher Tapp

In one of those reports, Carol found a phrase which, the more she read it, sounded out of place in the DNA world.

It was about pubic hairs.

which, in addition to the semen, had been found in Angie's body.

It was written in this lab report that it's similar or same as the victim.

And I said to myself, it's either Angie's or it's not Angie's.

It can't be an either-or.

Then Carol remembered reading an article about an internationally known DNA expert who just so happened to live and work right in Idaho.

This is the expert, Dr. Greg Hampikian, a fruit fly geneticist from Boise State University.

But Dr. Hampikian's work is not all done in the classroom.

In fact, his own path changed years ago when he was asked to test some DNA and got an innocent man freed from a Georgia prison.

And just like that, the doctor found a new calling, founder and director of Idaho's Innocence Project.

Secrets can be kept, I guess.

But, you know, science reveals those secrets.

So Carroll called this Dr. Hampikian and discovered that his innocence project had just taken on the case of Christopher Tapp.

At which he might have been forgiven for hanging up the phone.

But she didn't.

Quite the reverse.

Her words to me, I'll never forget, were, I just want to know what happened to my daughter.

And, you know, it still brings the hair up on the back of my neck.

The curiosity of hers surprised you?
