From NBI Studios, this is Truth Injustice, a crowdsourced investigation in real time.

I'm Bob Brown.

We've reached the point in our investigation where it's time to bring in the big guns.

This case is absolutely perplexing.

It's like nothing I've ever seen before.

On one hand, we have behaviors that indicate a clear attempt at concealing the crime scene

all at the same time we see other behaviors that undo the concealment.

Last week, I delivered my profile.

Since my belief that Vicki was the intended target, and John was expected collateral damage,

I believe that Becky interrupted the killers and was killed while attempting to flee.

I see a level of criminal sophistication that led to the case going unsolved for 10 years

and ultimately resulted in a circumstantial case against Robert and Christian.

Over the next few weeks, you're going to hear a different perspective.

I brought in one of the world's best and most well-known criminal profilers to weigh

it on the case.

Our conversation went on for over three hours and will be split up into three episodes.

This is season 12, episode 9.

Jim Clemente, part 1.

Texas Ranger James Holland is a legendary interrogator.

They call him the serial killer whisperer.

You can't hide those indications.

And that's why yesterday I knew that you did it.
