When I sent the results to Angie, she noticed that the orchid cell mark lab received the evidence for DNA testing

five months after the birth.

From NBI Studios, this is Truth Injustice, a crowdsourced investigation in real time. I'm Bob Ruff.

As all of you know, this case, the double homicide of Agnes and Lloyd Courtney, was brought to us by Alison Clayton of the Innocence Project of Texas.

The case was brought to Alison originally by a DNA analyst that had been reviewing it.

Dr. Angie Ambers was originally approached by Agnes's niece, Leanne Dofinot, a former judge, who asked her to take a look at the case materials.

It didn't take long before Dr. Ambers became convinced that something was not right with Debra Parenter's conviction.

Dr. Ambers agreed to jump on the phone with me this week to share her concerns.

I'll be honest, I was a little surprised during the conversation that you're about to hear that despite her expertise in DNA,

it wasn't necessarily the blood evidence that caught her attention.

Our chat did not go in the direction that I expected, but it was interesting nonetheless, and it led to a very interesting analysis towards the end.

Here's my conversation with DNA experts, Dr. Angie Ambers.

I'm joined on the phone today by Miss Angie Ambers. Angie is a DNA specialist and she is actually a big part of the reason

why we are investigating the murders of Agnes and Lloyd Courtney.

You heard Alison mention Angie briefly in episode one where she talked about how a DNA expert that she knows brought the case to her and wanted her to review it.

I reached out to Angie to it, she was gracious enough to get on the phone with us and explain why she thinks that this case needs a second look.

Angie, first of all, thanks for joining me.

My pleasure.

Before we get into the case, can you first lay out your background, your education?

You just before we hit record told me that you worked for a forensic scientist that pretty much all of our listeners will certainly know who he is,

but I'll let you explain how you have worked in the field, what your education is and where you're working now.

Sure, so I actually spent 20 years working in the Dallas, the Dallas Fort Worth area, which is how I became acquainted with this case and I can go into a little bit more details specifically about that later, but I'm a forensic geneticist, I'm a forensic DNA analyst, and I've spent my entire career focusing on highly challenged remains,
