This is Hidden Killers with Tony Bruske. Here now, Tony Bruske.

Donna Aitleson, there's a lot to break down. And today we got Robin Drake retired FBI special agent,

former chief of the counterintelligence behavioral analysis program with us to do just that.

And there's been so many things in this trial. This has been a trial that's totally

That behavior isn't a little bit suspicious.

It seems a little calculated.

So we're going to dig into this right now.

Robin, let's start with all this.

and immediately makes a controlled almost business-like call not to law enforcement

but to the very family member that is

implied to be part in this mini cabal of taking out the ex-son-in-law.

Yeah, so when we're looking at human behavior, what we're always doing is we're looking at, and as I've said
