[Nick Nigro speaking]

In the moment, it sounds like somebody who's scared, somebody who's panicked.

Somebody who is desperate.

And it's what I think many of us would expect to see and hear

from someone who has just come home and found a crime scene.

When I got here they were taking out the two bodies.

[news reporter] Prosecutors say a 21-year-old and her 48-year-old mother

were found shot to death in separate bedrooms

of this home on Scarborough Drive around 3.00 this morning.

Authorities say they were both murdered but won't comment on a possible motive.

[Nick Nigro] Uh...

This is a 25-year-old grown adult

who is still living in his parents' home, doesn't really have a job.

He doesn't have a meaningful sense of purpose or routine.

So what we see is this parasitic tendency,

which is absolutely a marker of psychopathic behavior.

Nigro is really putting on display this perfect relationship,

giving detectives what he thinks they want.

This is what we might call 'impression management'.

Nothing to see here. Everything was perfect.

[Nick sobbing]

[sniffles]

That is not someone who's experiencing genuine sadness.

He... He didn't have actual tears coming out.

Psychopaths often replicate emptions.

They'll try to say the right thing.

They'll try to do what they think is the most logical action at a certain time,

uh, to come off as, as normal.

He's first talking about her in this perfect relationship,

idolized way. He switches positions that

she must have been into something that I didn't know about.

And what we also see is that Nigro is making this all about himself.

"I have to get to the bottom of this, I have to figure this out, I'm confused."

It's now about his reaction, not two dead human beings.

It's a very common sign of someone who was lying

where they will, uh, change the narrative

and then they'll try to sprinkle in parts of the truth.

He's saying, "I have this drug problem. So look there."

And the drug problem is going to lead you to who did this.

He has a whole red herring figured out.

He has the whole story planned for how he wants this to go.

You see an arrogance that's emerging.

Somebody who thinks he's clearly smarter than the detectives.

Both detectives pull at the sweater string,

and then things start to come unraveled.

Because individuals who are psychopathic

and have an unhealthy level of narcissism or arrogance

can't resist taking that bait.

He, like most psychopaths,

often feel like they're the most clever person in the room.

They often feel as though no one can trick them,

and they have the skill to get what they want out of the world

by, by manipulating them and tricking them.

You can hear the escalation in his voice when he's emotional here.

He's so upset that they did not buy his story.

And I think there you can actually see genuine emotion coming out of him.

But it's just not for the reason that you would expect.

[Jonathan Deright] I hear him snapping.

He's saying these statements that he's doing it mockingly.

But, but it's an easier way to, to try to, um,

make it come across as, as truthful.

Detectives have tried a bunch of different strategies

and they might just have finally hit on one that was motivating to him.

And it's likely about Nigro saving face with his own parents,

and with his younger brother.

"They're gonna turn their back on me. And they're gonna move on."

And, "I know how I look to other people."

So it's manipulative in its own right, and it's self-serving.

[bleeping]

That moment when he looked straight at the camera and pauses,

we realize that this is all an act.

Maybe they're in the other room watching,

and maybe, and they might believe him this time.

[scoffs]

[bleeping]

He's very angry

that his attempts to control the whole situation is subverted.

And he's not able to keep his family out of this.

So he has his back against the wall.

He tries to change tact again.

[detective 1] Well...

Nigro's attitude is, he's doing them a favor.

I think it's still his attempt to try and stay in a position of power.

He's trying to control the narrative.

Part of the manipulation may be that he's hoping for leniency.

He's hoping if he gives them what they want,

they'll back out of throwing the book at him.

But what he also wants is for his family to be pulled out of this.

I wanted her to-- Yeah.

It's clear from the way he talks about his rage

that he feels emasculated.

So this starts to move us away from impulsivity

and more towards giving into the impulsive rage.

Majority of us may have urges at times to hurt someone or have them feel pain.

But we have enough internal regulation.

Psychopaths don't have that regulator.

[detective 2] Um...

He's talking about it almost like they're not real people, they're puppets.

And that lack of emotion, that lack of connectedness

to somebody that he was prepared to marry and live with

really highlights that lack of emotional experience.

He really has this mentality of 'it's me against the world.'

We see that a lot in psychopaths.

Uh, he's really tried to make himself believe,

if I wouldn't have done this, she would've done it to me.

I had to protect myself.

[siren wailing]

Nigro is telling us that he's not sadistic,

and yet, he's also told us that he deliberately chose to kill her mother first

so that his girlfriend would be aware that her mother was being killed,

which is nothing short of a sadistic act.

He really portrays himself as a victim of women.

When really, he was the one victimizing women.

I think that what we're all thinking when he's saying that is,

he says, "I created a monster."

And the natural progression is,

"Are you talking about a monster in you, or in her?"

Years of relationship.

Yeah. Yeah.

[Nameeta Sahni] Nigro understands he tried

to give a narrative that wasn't believed.

He's accepting his fate.

And because people are dispensable to him,

he's projecting that onto his mother and brother.

They're gonna turn their back on me.

I think at this point what we're seeing is somebody who's accepting his reality.
