The thing inside of me, it's like...
the appetite -- it's like a wolf that's...
feeling the hunger.
REPORTER: Police arrived at the Orlando apartment of 23-year-old
Ryan Doyle and found the body of his girlfriend,
25-year-old Lora Fischer, dead from multiple gunshot wounds.
Doyle was nowhere to be found.
Investigators located Doyle hours later
in an emergency room more than 500 miles away
in North Carolina with gunshot wounds to his shoulder.
At this point in the investigation,
they are aware that the suspect's girlfriend
has been found dead in his apartment,
and he has fled the scene of the crime.
Doyle doesn't do what the rest of us would do.
He doesn't call 911. He doesn't try and revive her.
He doesn't call for help or scream for help
with any of the neighbors.
He packs his stuff, and he leaves.
TUSSEY: He's difficult to engage with.
He might be intentionally trying to manipulate
the situation by being so flat
and not sharing any vulnerabilities
or information.
Individuals who are psychopaths tend
to have this very flat affect.
They don't respond to the typical emotions
like you or I might.
One of the markers of the psychopathic lifestyle is
not being able to hold a job,
not being able to have relationships,
being manipulative, and irresponsible.
Here, we have a little sort of taste of that.
It's not really clear if he's going to school,
but he's borrowing money, relying on his aunt.
He's drawing from someone else,
but he's not doing anything with it.
Doyle's telling us that he's been
clean and sober for eight months.
But what we know from
the record is that's not entirely accurate.
There's a history of drug use.
We also know based on neighbors' accounts that he was
on again, off again using alcohol.
And when you already have an individual who struggles
with impulsivity
and then you increase that impulsivity with drug
and alcohol abuse, you essentially have
a powder keg for some pretty negative behavior.
Someone with psychopathic traits may talk about
very violent, repulsive behavior as if they're going to
the store to buy a jug of milk, with really no outward
expression of their emotion.
Doyle wants this female detective specifically to
believe that he's the chivalrous
man who's trying to protect his old lady, and Darren
was aggressive, he was the perpetrator.
He's trying to get her to believe
he's this good guy who would protect women.
We know that that's just farther from the truth.
RAGHAVAN: He wakes up, and the woman that he has
claimed is his girlfriend is covered in blood
and he is not particularly
bothered by that.
He's more bothered by how he has suffered.
The indifference to the suffering of his girlfriend
feels very much like a marker of psychopathy.
TUSSEY: Doyle is really distancing himself
from his girlfriend, now referring to her
as "that girl," and he almost preemptively
provides a, "Don't worry, I'm not lying.
I'm telling you the truth."
I think that that's his attempt to hopefully stop her
from asking any other questions
or doubting him in any way.
As Doyle's aunt is being called in to the interrogation,
his body language changes.
He goes from being open and somewhat comfortable, relaxed,
laid back, to he's now pulled his body parts together.
He's crunched together almost in a somewhat fetal position.
He's not in control anymore.
Individuals who are psychopathic like to maintain
a sense of control when they're dealing
with the authorities.
Now it's gonna get uncomfortable,
because he has a mother figure
in the room, trying to be his moral compass.
He says to his aunt, "I don't remember shooting her."
This is quite a shift from the entire rest of the interview
where he's basically said,
"D came in, D shot her, and shot me by the way."
But now, unsolicited to his aunt,
he says, "I don't remember shooting her," almost
as if he's taking responsibility,
but he's saying he doesn't remember it.
RAGHAVAN: He has feelings for his aunt
and doesn't want to disappoint her.
She clearly is familiar with his rages, his drinking,
his episodes, his fights, and perhaps
Doyle thinks that she's gonna get,
you know, she's gonna bail him out of trouble.
And despite all the other things happening,
the lack of remorse, the shallowness, the glibness,
a part of him is more human when she's in the room.
And that part that's more human is not able to
lie in the complete way he can to a stranger.
SAHNI: He's now willing to say he committed the crime,
but the detective knows that he knows more details
than he's telling them.
Doyle doesn't want to say these things in front
of his aunt, because now the impression management has
switched to the aunt.
He doesn't want this one and only person who has protected
him his whole life, taken him in
every time he's failed and he's messed up,
to think less of him as a person.
SAHNI: He's saying, "If she had just left me alone,
this wouldn't have happened."
And that is squarely the kind of behavior that we see with
psychopathic individuals is this
inability to take responsibility for their own
violence and aggression and the harm they cause others.
And what we know about psychopathic individuals is
that they don't typically like to be challenged.
And that may have been what kicked off the violence.
Investigators were going through his phone.
They found hundreds of photographs and video
recordings of women in quite explicit sexual positions.
And what's so disturbing,
what's so upsetting are the women sort of saying, wait,
stop or don't appear to know that they're being recorded.
Doyle appears to be a sexual psychopath,
really dominant, aggressive, and enjoying hurting women.
Individuals with psychopathic traits have a difficult time
reining in their rage,
and pair that with their lack of remorse
and their callousness for hurting other people,
they lash out without really even thinking
about what it means for the other individual.
They also have this grandiose sense of
who they are and what they've accomplished.
How dare she question him and the way he wants
to spend time with his brother.
She should have known better, in his perception.
He is a messy and disorganized, impulsive killer.
So he does go to great lengths to try to help himself,
but he's not very good at covering up the murder scene.
And so he shoots himself to sort of bolster
the story that somebody invaded the house and shot him.
The way he's trying to avoid blame is
by making himself into a hero and a victim
at the same time -- he may regret that he was caught,
but he certainly doesn't feel guilty that this woman is dead,
this young woman who has two children.
