MAN: There's this thing inside of me, it's like...
the appetite.
It's like a wolf that's...
filling...the hunger.

MORGAN: He's gonna start with just flat-out denial,
which isn't believable.
Just because someone psychopathic does not
mean they're intelligent about how to lie well.
RAGHAVAN: But he adds different things that he hopes will make
him seem vulnerable and authentic,
such as, "I know this doesn't sound right,
but it's actually the truth."
But there's blood everywhere.
So it's a careless, impulsive murder with
no forethought and no thinking about what would happen.
Being choked is a sign of extreme danger.
It was happening after they broke up.
He feels she doesn't have any right to break up
the relationship, and he chokes her,
because he feels that she's betraying him.
He feels entitled, because he owns her.
The word mostly, it's a very telling term, which means
there's a story there -- she goes, "It's mostly tame,"
which means it's not always tame.
Here's some excerpts from her diary.
Blair writes, "Sean makes me so mad since he moved in.
"He can be such a jerk sometimes.
"He needs to change his damn attitude,
stop snapping at me for stuff he did."
To the police,
she's minimizing how tempestuous
the relationship was in the household.
He's snapping at her, and we know that he choked her.
This blaming other people or externalizing responsibility is
one of the signs that we see in psychopathy.
Alex has had very clear
characteristics of autism spectrum disorder.
You can see it in his language.
He's very pedantic. He's very exact.
Alex has a limited
understanding of friendships and empathy,
and he thinks Sean is his best friend for thousands of years.
And the way that these two
come together is a recipe for disaster.
Sean's psychopathic traits are going to make him very quick to
exploit the weaknesses in other people
and figure out how he can use them to his own advantage.
[Smoot sighs heavily]
MORGAN: His identity is fused with Sean Turkot.
Psychologically and emotionally,
it sounds like he accepted the idea
that seeing Eddie alive was killing Sean.
So helping him get rid of Eddie would help Sean live.
RAGHAVAN: He seems so completely under the spell of Turkot,
and he has internalized Turkot's self pity
in a "blame the world" narrative,
which is a very psychopathic and [indistinct] narrative.
It really feels like a cult leader
and a cult follower type of relationship.
And so there's a, element of brainwashing, loyalty,
devotion, and willingness to commit crime for him.
MORGAN: He is now framing things differently.
He doesn't have aggression towards Eddie.
I didn't hate him.
I actually liked him. He's my friend.
I felt sorry for him.
Psychopathic people, they will
try and shift blame to someone else.
So he's shifting it to his ex,
and he's lying,
but he's really trying now to manipulate the circumstances
so that he can come out and look good.
MORGAN: A little over a week before Eddie was murdered,
Sean sent a message to a friend on social media.
"She loves hurting me, and so does Eddie.
"I would love to take him out in the woods
and hunt him like the pig he is."
And then he writes, "I simply want to kidnap him and kill him
at Rock State Park,
take him out to Allegheny Forest, and dump his cold, dead
corpse in the roaring waters so the sharks can eat him.
It isn't just a vague thought of killing him.
He's actually now articulating a plan for committing murder.
He's describing the location of where
the body is, in fact, found,
so it's not smart, but he's not even ashamed of
his feelings.
These are signs that we see in psychopathy.
MORGAN: When Sean Turkot's making these comments,
we're really learning more about him,
because we know that he attributes blame
to other people.
He attributes emotional states to other people.
Um, and so it's possible that
he himself experiences a death wish.
Um, but he'll say anything right now to keep diverting
the police officers' attention to somebody else in order to
still appear like he's the victim in the story right now.
He had recruited a friend who would do anything for him
and manipulated him to
help him get it done and then is willing to throw him
under the bus,
which lets you see the lack of empathy,
the lack of a genuine bond.
There's no regard even for Alex's feelings.
He'll ditch his friend right away.
Psychopaths really, uh, want to use people as chess pieces
in -- in the game of life.
That -- that's how they see other people.
If they can't get around them, they need to move them
out of the way, with force.
I'm not buying that emotion that he just had there,
when he says he's the only friend I've ever had.
He has kind of a crack in his voice, but he's really crafty
in that he's probably able to hold it under this facade of
being a good guy.
I think he's explaining in a very honest way,
even if it's immature, why he feels he needs to protect Blair.
The way he idealizes and devalues, particularly Blair,
but also, interestingly, Eddie, are very much part of how
he splits into good and bad.
She's horrible and manipulative,
so the boyfriend needs to go -- other times, she doesn't stand
up for herself like my mother, and so I need to do it for her.
We don't know the full story, and we only know
what Sean Turkot says,
but this kind of splitting, meaning idolizing and then
devaluing the person based on
your emotional turmoil is almost always
because of abuse.
The story that he tells only emphasizes his nobility.
He couldn't possibly have been a decent father.
He's violent man who is financially unstable.
But the abuse he suffered doesn't
justify the terrible way he treats women
or the fact that he murdered his girlfriend's boyfriend.
