[man] The thing inside of me is like..

the appetite, it's like a wolf that's...

feeling...

...the hunger.

[foreboding music playing]

[TV reporter] Authorities say residents at this duplex on North 22nd Street

contacted police after finding burned clothing,

sneakers, and human remains inside a garbage can.

The burnt material matches what John Swain had been wearing

when he was last seen.

Another resident returned home from vacation

to find bloodstains on her rug.

[Alexander] Crowe communicates a great deal by his body language.

We have an individual being interrogated

by two detectives who's cool as a cucumber.

So that gives us a good window in terms of just

how devoid of emotion he is and how unworried he is.

[Dr. Bryanna] It seems clear that Dawnie is not only afraid of him,

but she doesn't trust him with his daughter, and he's hit her sister.

This is a very aggressive, violent, versatile criminal

who's just doesn't obey the law

and doesn't think the rules apply to him.

[eerie music playing]

They seemingly go out and meet this young boy,

18-year-old John Swain.

They lure him back to their house, bashing his head in

and Clark doesn't sound scared or upset.

He tells it like he's explaining how he went to the grocery store,

which is not what a normal person would do.

On paper, Clark looks a lot cleaner, right?

He's very careful in presenting himself as the unwitting witness

to Crowe's demonic plan.

Maybe Clark is just a little bit better at hiding and dissimulating

his real intentions and his real acts than Crowe is.

[Alexander] You might not remember what you had for breakfast, right?

But you're gonna remember cutting up a body.

And the fact that he refers to this

human being, recently deceased, as 'It'

is further proof of the objectification of the victim.

And that's very consistent with the way a psychopath thinks.

[news reporter] A new development in the case of 18-year-old John Swain.

Bismarck police say they got a tip that Swain was buried in the backyard

of this Montana home where Theo Crowe lives with his mother.

Clark tells us, "I'm going to fully cooperate."

Crowe says, "I'm here to give a confession."

Both are vying for control of the interaction with the detectives.

[Alexander] They want to get ahead.

They want to push their narrative.

So that they can control the outcome.

And that's very psychopathic.

I think that the way they went about selecting their victim

is illustrative of some pretty significant

psychopathic or antisocial tendencies.

They identify a younger individual of smaller stature.

Purposefully choosing somebody who's isolated.

It really feels like they view John

as almost a pawn in a game that they're playing.

[mysterious music playing]

[thudding]

There's not a whole lot of research about whether psychopaths

essentially draw each other, but it makes sense.

Imagine if you can find somebody who's like you,

who wants to go and do these horrible things

and doesn't really feel bad about it.

If anything, egging each other on and showing each other.

This is totally okay to be this way.

[Alexander] He catches himself in the end again,

he feels compelled to say that it was hard emotionally.

I think he had to add that just because

he heard himself speak, and it sounded horrible.

At the end of the day, even when psychopaths

may not know what they are,

or they may not recognize it entirely in another person.

They still know not to trust each other

because this guy will do the exact same thing to me

that I'd be thinking about doing to him.

When people think of psychopaths,

they think they have absolutely no emotion, and that's actually not true.

Here we see Crowe all of a sudden feeling upset

because he feels very bad for himself.

[Dr. Bryanna] He feels not at all bad for what they did to John Swaine.

[man behind camera] 15:59 hours.

Removing the tarp and bagging it up.

I think both Crowe and Clark had violent and homicidal fantasies

that they brought out in each other and that that partnership

allowed them to express desires

that they had not had the outlet for in the past.

The debate is constantly, which is the worst psychopath.

The factor 2 type psychopath, which is more antisocial.

They're typically are violent and aggressive.

Or the factor 1 psychopath

who tends to maybe blend in more with society,

tends to be more manipulative, charming, cunning.

Which causes more damage? Which is worse?

I would say the factor 1,

the type that is more akin to Clark.

So I always find the chameleon to be a little more dangerous.

[reporter] Clark is sentenced to life in prison

for his role in the murder of a South Dakota teenager.

20-year-old Joshua Clark was convicted in July

for his role in the killing of 18-year-old John Swain.

His co-conspirator, 26-year-old Theo Crowe also received life.

Though justice was served, Swain's parents, Pat and David,

say the brutality of the crime still haunts them.

Because it was senseless.

[Pat] It was so horrible.

It was just a total disregard of human life

because there was no reason, none at all.
