- There was no smoking gun in this case.
It really came down to the interview.
We knew we had to get at least an admission.
And of course, best case scenario a confession.
(ominous music)
- We felt we knew Karl well enough
that somebody needed to listen to Karl run his mouth
and we decided John was gonna be the guy
that Karl would align with.
He would bond with him.
(door opens)
(groans)
- As it turned out it wasn't hard getting Karl to talk
but he quickly turns the conversation to himself.
Oh my back now is hurting.
Or he'll just kind of switch the topic.
So you try everything you can think of
and hope something sticks.
And hope you get some kind of revelation from the person.
(suspenseful music)
- He deflects a lot.
You'll hit him up with something
and then he'll just kind of switch the topic.
(ominous music)
- He was inappropriate, the way he talks about some stuff
and I'm not as expert at some people by no means.
But the one thing that I think is a constant
with someone that's sociopathic is that they're really good
at mimicking emotions, but they don't really feel them.

- And the house and I've been talking to realtors.
(ominous music)
- Time is our ally.
It may last 40 hours.
It may last two days.
Until he stops us, we're not stopping.
We are never quitting.
- All of a sudden it seemed like, yeah,
he started to become emotional.
So I kind of stepped up the physical contact,
putting the hand on the shoulder,
soothing the tone of voice, encouraging him, let it out.
(Karl crying)
(Karl groaning)
(suspenseful music)
- I think we actually saw
some of the real person there for a few moments, anyway.
He kind of went back into deflection mode after that.
I think he had pretty much decided
that's all he was gonna give us.
(ominous music)
Alright.
- At that point, it becomes a little personal.
And I want to let him know what I truly think of him.
There is never gonna be justice
but we had to bring some type of closure to the family
who had been tormented for so many years and so many times
by this evil monster.
- He showed no emotion at all.
Investigator Crowley and I walked him over
to the jail to be booked in
and he actually wanted to shake our hands
and he said, You guys did a good job.
