16 Hours of Lies? The Lost Confession Tapes & The Birth of Modern Profiling

And Doug, there's nowhere I wouldn't go to help someone customize and save on car insurance with Liberty Mutual.

Even if it means sitting front row at a comedy show.

Hey everyone, check out this guy and his bird. What is this your first date?

Oh no, we help people customize and save on car insurance with Liberty Mutual together. We're married.

Ah! Mito a human, him to a bird.

Yeah, the bird looks out of your leg anyways.

Only pay for what you need at Liberty Mutual.com.

Liberty, Liberty, Liberty, Liberty, Liberty.

Imagine for a second moving to a brand new city.

Right, like just a totally fresh start.

Exactly. You are 19 years old and you are absolutely buzzing with that very specific kind of electric hope that you only really get when your entire adult life is just this big blank canvas.

Oh yeah, that feeling of invincibility.

Right, so you unpack your bags, you look out the window at the skyline and you are completely ready to conquer the world.

But instead of starting this brand new chapter, you actually become a victim on your very second day in town.

It's just, it's unimaginable.

It is. And to add a deeply macabre like an almost unthinkable insult to injury.

The killer leaves a cheerfully sinister happy new year card, which carefully right between your toes.

Which is just so incredibly shilling.

It really is. And I want to be entirely clear right off the bat here with you listening.

We are not dissecting a movie script today.

No, not at all.

This isn't some Hollywood thriller cooked up in a writer's room.

Yeah.

This is a genuine documented forensic detail from one of the most paralyzing crime sprees in American history.

And you know, it is exactly that kind of detail that turns a standard homicide investigation into like this massive psychological labyrinth.

Right, because of the messaging.

Exactly. Because the moment you introduce a prop like that greeting card, it is no longer just about the grim mechanics of violence.

It becomes an active form of communication.

Yeah, a twisted conversation.

Right. You are dealing with a predator who is treating the crime scene like a stage.

He's actively playing a high stakes psychological game with both the authorities and the public at large.

Which is exactly the terrifying terrain we are navigating today.

So welcome to Thrilling Threads.

Thrilled to be here as always.

Today our mission is to completely deconstruct the anatomy of a citywide panic.

We are going to look at the painful and honestly often clumsy evolution of modern criminal investigation.

Incredibly clumsy at times.

Yeah.

And we're going to explore the horrifying reality of a killer who bypassed every lock, every alarm, because his victims simply will they just open the door form.

And just to give you a solid foundation for where we are pulling all of this from today.

We are drawing on a literal mountain of historical records.

So many documents.

Oh, tons.

The original declassified police case files and the really sharp retrospective insights of modern criminologists and historians.

Really want to make sure we're getting all the angles.

Right. We are heavily referencing the exhaustive research of experts like Lawrence, Natalia, Austin, Sammy, Mike, John, and Matthew.

All of these folks have spent years just dissecting the source materials surrounding the Boston Strangler case.

And we are taking all of those disparate perspectives.

So the forensics, the psychology, the historical sociology, and we're weaving them together for you.

Because we really want to challenge the fundamental assumptions you make about your own safety.

Yeah, that false sense of security we all have.

Exactly.

We are going to explore the dark, cascading psychology of trauma and look very closely at how 1960s law enforcement had to completely change.

I mean, they were essentially built on just walking the beat and talking to informants.

She'll leather detective work.

Right.

And they had to radically and painfully reinvent their entire methodology just to catch a ghost.

It's wild.

This shift from that analog detective work to the very dawn of data-driven profiling.

It's one of the most fascinating sub narratives of this entire case.

You really is.

So let's plunge right into the timeline.

We were starting in June of 1962.

Okay, setting the scene.

Right.

We're in Boston's back bay neighborhood.

It is a Sunday.

Anna Slessers, a 55-year-old divorcee, is scheduled to attend a memorial service at her church.

Just a normal weekend routine.

Exactly.

Her son, Juris, arrives to pick her up exactly as they planned.

But Anna doesn't come out.

Right.

Juris stands at her door, knocking, calling out.

And he ends up waiting for 45 excruciating minutes.

And I actually want to pause on those 45 minutes because from a psychological standpoint, that is an absolute eternity.

Oh, it's agonizing.

When you are standing outside, a loved one's door like that, your brain just starts running a terrifying diagnostic.

You go to the worst case scenario.

Well, first you cycle through irritation, right?

Like, come on, we're going to be late.

Oh, sure.

Yeah.

Then it shifts to concern, and then outright panic.

And Juris knows his mother is meticulous about church.

But he also knows she suffers from severe, documented bouts of depression.

Ah, right.

So that colors his whole perspective.

Exactly.

So as the silent stretches on, his mind, naturally, almost protectively in a weird way, gravitates toward a tragic, internal explanation rather than some kind of external threat.

He thinks she heard herself.

Yes.

He assumes suicide.

Okay, let's unpack this.

Because he finally makes the call to force his way in.

And the scene he finds is just, it's the absolute worst nightmare of any child.

Truly horrific.

There is lying on the floor near the bathroom, and she's ice cold.

And the belt of her own bathrobe is wrapped securely around her neck.

Right.

So based on his pre-existing knowledge of her mental health, Juris immediately calls the police and reports the suicide.

Which, again, is entirely logical for Juris in that traumatic moment.

He is interpreting the physical evidence through the lens of her psychological history.

It makes total sense for him to think that.

It does.

But when the detectives actually cross the threshold, they aren't looking at her emotional history.

They are reading the room forensically.

Right. They have a totally different lens.

And immediately, the physical evidence violently contradicts the suicide theory.

The juxtaposition is honestly what gets me.

Yeah.

I was reading Natalia's analysis of the crime scene photos.

And the domestic normalcy of the apartment is just jarring.

It really is.

There are fresh baked muffins sitting on the kitchen table.

There is a kettle resting on the stove.

Right.

I mean, I don't care how deep a depressive episode is.

The psychological momentum required to bake muffins and put the kettle on.

That does not align with someone who, ten minutes later, decides to end their life.

No, not at all.

It looks like someone who was briefly interrupted while preparing breakfast.

And that is the absolute hallmark of a blitz attack.

Yeah.

The police quickly confirmed that Anna had been sexually assaulted.

But the detail that completely obliterates the suicide theory

and the detail that would eventually define this entire panic is the bathroom belt itself.

Right.

How is used?

Yes.

It wasn't just utilized as a simple ligature.

It was tied under her chin in a very deliberate, perfectly symmetrical bow.

A bow, like a gift.

A bow.

And, you know, you do not tie a decorative knot when you are in the desperate, agonizing throws of taking your own life.

Obviously not.

It is an external signature that is a killer leaving a deliberate, highly personalized mark on the scene.

It's so twisted.

It is.

And it brings up this really fascinating, criminological debate about methodology among the experts we researched.

Why use the victim's own clothing?

Why the bathroom belt instead of bringing, I don't know, a grote to a rope?

See, I'm actually stuck on that, too.

If this killer is confident enough to meticulously stage your body entire decorative bow,

why risk relying on finding a weapon in the apartment?

That's a great question.

Doesn't relying on a weapon of opportunity suggest this wasn't really premeditated.

Like, maybe it was just a burglary that escalated into a panic.

So that is a brilliant pushback, and it's exactly what the initial detectives likely debated in that room.

Yeah.

Because in behavioral analysis, using a weapon of opportunity often does point to an impulsive, disorganized crime.

Right.

Like a crime of passion or a break-in gone wrong.

Exactly.

However, the application of the weapon here totally changes the map.

How so?

Well, yes, he used what was available.

But manual or ligature strangulation is an incredibly intimate, physically demanding way to kill someone.

Takes a lot of strength.

It takes strength, and it takes minutes of sustained effort.

To do that, and then take the time to fashion a bow, displays a terrifying level of psychological control and expressive violence.

Yeah.

It's not a panicked burglar.

It's an offender who is so utterly confident in his physical dominance that he doesn't need to bring a weapon.

He knows he can subdue her with literally whatever is lying around.

That level of arrogance is just chilling.

And it perfectly sets up the locker room mystery element of this case, which is wild.

Oh, the locker room aspect is baffling.

Because the forensics yielded absolute nothing.

There were no foreign fingerprints.

The neighbors in the adjoining apartments heard absolutely no struggle, no screams.

Nothing at all.

And most importantly, there was zero sign of forced entry.

Right.

The lock wasn't picked.

The door wasn't jimmied.

No windows were broken.

It's like the ultimate Trojan horse scenario.

That's a perfect way to put it.

I mean, the scariest monster isn't the one shattering your glass in the dead of night.

It's the one you willingly invite into your home for tea.

It fundamentally subverts the entire architecture of domestic security.

Yes.

Think about it.

The door is our primary boundary against the chaos of the outside world.

But what happens when the threat knows the exact social script required to make you open that boundary yourself?

It makes you question everything.

Yeah.

But at this specific moment, right, in mid-June 1962, the Boston bullies don't know they have a serial predator yet.

No, they just think it's a tragic anomaly.

Exactly.

They just have this one deeply weird, incredibly strange murder.

Weeks pass.

The trail goes cold.

Until it doesn't.

Right.

Then, the killer loudly announces that Anna Slesers was not a one-off event.

Because a single bizarre murder is an isolated tragedy.

But the moment the highly specific, impossible circumstances of that crime repeat themselves, the entire investigative paradigm shifts.

And this pattern really solidifies during one of the most punishing heat waves in Boston's history,

which adds such a crazy layer to the story.

Oh, the environmental factor is huge here.

We really place ourselves in that environment for a second.

It's late June.

It is a sweltering, oppressive, Boston summer.

We were talking about the early 1960s, long before central air conditioning was like a standard utility in every apartment.

He basically had fans and open windows if you were lucky.

Exactly.

The physical reality of living in a brick apartment building in the back bay during a heat wave means you desperately need to leave your windows open to catch any kind of crossbreast.

Otherwise, you're basically in an oven.

Right.

Suddenly, as rumors of a killer start to circulate, there is a very real, paralyzing fear of doing exactly that.

It creates this absolute pressure cooker environment.

The residents of Boston are essentially trapped, baking in the heat of their own locked departments,

because the alternative feels like an open invitation to a phantom.

It's awful.

The physical discomfort really amplifies the psychological terror.

And right in the middle of this awful heat wave, we look at the case of Nina Nichols.

She's a 68-year-old retired psychotherapist.

And just trying to go about her day.

Yeah, to escape the stifling heat of her apartment, she decides to go shopping for the afternoon.

And according to the timeline, meticulously laid out by researcher Sammy, she returns home around 5-0-0-0 p.m.

And begins getting ready for a planned dinner at her sister's house.

But 7.30 p.m. rolls around, and Nina hasn't shown up.

Right.

And here we see that exact same ripple effect of anxiety that we saw with Jurislazers earlier.

The sister calls, gets no answer, the panic escalates.

It's that same building dream.

Yes.

She drives over, knocks on the door, and eventually has to track down the building janitor to open the apartment with a master key.

And what the janitor finds is horrifying.

Nina is in her bedroom.

She is positioned half on, half off her bed.

And around her neck is a nylon stocking.

The scene itself is chaotic too.

The apartment has been heavily ransacked.

Right, drawers pulled out, stuff everywhere.

Exactly.

Belongings just scattered.

To a beat cop walking in, it immediately reads as a burglary gun catastrophically wrong.

Which would make sense on the surface.

It would.

But criminologist Mike highlights a detail in the files that completely rewrites the narrative.

Her cash is sitting right there in plain sight.

Which is the ultimate tell right.

If you are risking a breaking and entering charge, let alone a murder charge,

you do not leave the untraceable paper money behind.

Precisely.

The fact that the cash is untouched proves the motive is completely divorced from financial gain.

The ransacking is actually a behavioral artifact known as staging.

Okay wait, I need to jump in here.

Usually staging is done by someone who knows the victim, right?

Typically yes.

Like a husband killing his wife and breaking a window to make it look like an intruder did it,

just to throw the cops off his trail.

Why would a random serial killer bother staging a robbery?

That is exactly how staging was understood by the FBI at the time.

It was viewed purely as a defensive countermeasure by a known associate.

So why do it here?

Because in this case, the staging isn't defensive, it's almost theatrical.

It's the killer actively playing a game with the detectives.

Oh wow.

He wants them to briefly think it's a robbery only to realize the horrible truth when they look closer at the victim

because the staging is immediately betrayed by his own psychological signature.

The bow again.

Yeah.

The nylon stocking used to strangle Nina Nichols wasn't just pulled tight and nodded.

It was fashioned into that exact same grotesque bow.

It's so dark.

It takes the murder weapon and transforms it into a macabre presentation.

It suggests the killer who views his victims not just as targets but as objects to be arranged and wrapped.

And the timeline here is what genuinely breaks my brain.

Because on that exact same day,

15 miles north of Boston in the relatively quiet suburb of Lynn,

police are dispatched to another apartment.

Right.

Helen Blake, a 65-year-old divorcee is found murdered.

The methodology.

Manual strangulation utilizing a nylon stocking.

The signature tied in a bow.

And the entry point.

Absolute no sign of forced entry.

The physical and psychological stamina required to execute this timeline is staggering.

And it completely shatters the existing behavioral models of that era.

I mean, I have to stop you there because how is that even physically possible?

Yeah.

Two manual strangulations in a single day separated by 15 miles of 1960s traffic.

It's a logistical nightmare.

Right.

And we always hear about serial killers needing a cooling off period.

Hmm.

They commit a horrific act, the psychological tension releases,

and they recede into the shadows for weeks or months to decompress.

You're touching on a fundamental pillar of traditional profiling.

The cooling off period is what distinguishes a serial killer from a spree killer.

But this offender completely defies that gravity.

Strangulation is not like pulling a trigger from across the room.

No, it's very hands-on.

It requires immense sustained physical exertion.

It is exhausting.

To complete that act, meticulously staged the scene,

tied a signature bow, travel 15 miles,

successfully conned his way into a second apartment and do it all over again in the span of hours.

It's insane.

That suggests an offender operating in an absolute fugue state of adrenaline.

Or someone whose compulsion is burning so hot that a cooling off period is just impossible.

It is a level of brazen frenzy that absolutely terrified the profiling community.

It's like a Category 5 hurricane.

Right.

The physics of the escalation suggests it simply cannot be stopped by normal friction.

Right.

And the moment the detectives in Boston and the detectives in Lynn compare notes.

And they realize the undeniable signature linking these three women,

the lack of forced entry, the nylon or belt, the decorative bow,

the entire weight of the investigation shifts.

It transitions from a series of localized tragedies into a unified existential threat.

Everyone is on edge.

Yes.

It is the entire greater Boston area realizing they are being hunted by a single cohesive entity.

And that realization forces the authorities into a posture of absolute desperation.

And naturally the press gets wind of the bow signature.

Oh, of course they do.

You know the media is going to run with a detail like that.

They officially christen the killer, the Boston Strangler.

Which is just a terrifying moniker.

Just hearing that name in the daily papers incites mass hysteria.

Hardware stores sell out of deadbolts.

Locksmiths are working around the clock.

People were terrified.

And the police are standing there, empty handed, unable to find a single connective thread between these victims,

other than the grim mechanics of how they died.

I mean, they didn't go to the same church.

They didn't shop at the same stores.

They didn't share a milkman.

Historian John makes a brilliant point about the sociological pressure of this exact moment.

When a killer operates this randomly, the pressure on the police department ceases to be merely about solving a homicide.

What does it become?

It becomes about restoring the fundamental social contract.

Ah.

The public feels that the basic agreement of civic life,

that you are safe behind your own locked door, has been violated.

The police aren't just hunting a man.

They're trying to save the city's sanity.

Which leads us to Boston Police Commissioner Edmund McNamara.

Right.

He is a veteran of the force.

But he is relatively new to the top job.

He is watching his city lose its collective mind.

And he decides he has to take drastic unprecedented action.

Very drastic.

On July 2nd, he issues a mandate.

He takes every single detective on the Boston Police Department every single one.

And assigns them exclusively to the strangler case.

The logistical shockwave of that decision simply cannot be overstated.

It is an administrative earthquake.

Let's really gain this out for the listener.

Because assigning every detective sounds amazing in press conference.

Oh, it sounds fantastic.

We are putting 100% of our resources on this monster.

Exactly.

But in practice.

It's like trying to fix a delicate Swiss watch by having 50 people simultaneously poke at the gears with screwdrivers.

That's a great analogy.

More hands do not equal more precision.

They just create gridlock.

What happens to the city's other crimes?

What happens to the armed robberies, the auto thefts, the other homicides?

They fall by the wayside.

And more importantly, how do you even process that much information on one case?

You don't.

And that's the ultimate tragedy of McNamara's decision.

It almost certainly caused massive informational gridlock.

Just too much data.

Way too much.

When you have hundreds of detectives independently chasing down thousands of citizen tips, interviewing witnesses,

and typing up physical carbon copy reports without a centralized, efficient way to cross-reference that data,

you get absolute paralysis.

Right, because there's no digital database.

Exactly.

Detective A in the north end might interview a suspect with a green jacket.

Meanwhile, Detective B in the south end has a witness who saw a man in a green jacket.

But those two pieces of paper will literally never meet in the filing cabinet.

That is so frustrating.

The sheer volume of raw, unfiltered data becomes a weapon against the investigation itself.

And the killer clearly recognized that the police were flailing.

Because the strangler continues to strike.

And crucially, the profile of the victims begins to shift in a way that throws absolutely everything into chaos.

A very terrifying shift.

Up until now, the victims were older women.

But in the late November of 1963, 23-year-old Joe and Graf, a young industrial designer, is found strangled in her apartment 30 miles north of Boston.

A huge change in demographic.

Huge.

And then just weeks later, we arrive at the tragedy mentioned in the intro.

19-year-old Mary Sullivan murdered in the heart of the city on her second day living in Boston.

Right.

The scene features the exact same methodology.

The ligature, the strangler's not, factioned into a bow.

And that taunting New Year's card wedged between her toes?

Yes.

If we look at this shift through the lens of modern behavioral science, the escalation in victimologies profound.

Initially, the killer strictly targeted older women.

Anna was 55, Nina was 68, Helen was 65.

Repairing consistent.

But jumping down to a 23-year-old and a 19-year-old,

shatters that rigid victim type model.

Usually, a highly organized serial offender hones in on a very specific physical demographic that fulfills a rigid psychological fantasy.

So what does it mean when they change types so drastically?

To drastically alter the age demographic suggests an offender who is either psychologically unraveling,

or an offender whose compulsion is driven more by the opportunity of access than by strict physical preference.

And that New Year's card, I just cannot shake the image of that card.

It is so arrogant.

It's not just a killing, it's a performance.

It is a direct unilateral dialogue.

It is a brazen display of a god complex.

Yeah.

The killer is fully aware that literally every detective in the city of Boston is looking for him.

And yet he feels so supremely confident, so untouchable, that he lingers at the crime scene to arrange a prop specifically to mock them.

Unbelievable.

He's telling the police, I own this city, and you are powerless.

And honestly, at that point, he was kind of right.

The Boston Police Department is drowning in carbon copy reports.

The public panic is causing economic and social disruption, and the murders are continuing.

Things were bleak.

Very bleak.

Eventually, a higher power has to step in.

The floundering at the local level has to be stopped.

And this necessity leads to a revolutionary and incredibly fraught shift in the history of American policing.

Because the state government realizes it can no longer just stand by while the city fails.

Two weeks after Mary Sullivan's murder, Massachusetts Attorney General Edward Broke invokes his authority and legally strips the case away from the Boston Police Department.

Wow.

We have to unpack the historical and sociological weight of this move, because context is everything here.

It really is.

Attorney General Broke is a brilliant legal mind, and he is also an African-American man, a black Republican.

In fact, stepping in to take direct authority over the Boston Police Department in the early 1960s.

Which was a massive deal.

And sources note that the BPD at the time was predominantly white, fiercely Irish Catholic, highly insular and notoriously proud.

The racial and political friction of that takeover must have been absolutely blinding.

Oh, it was a tectonic clash of cultures.

The Boston Police Department viewed themselves as the absolute sovereign authority on their own streets.

To have the state government step in and declare them incompetent is inherently insulting to them.

Right.

But Broke compounds that institutional insult by how he structures his new command.

He doesn't just put state police brass in charge.

He brings in civilians.

Right.

Broke assigns the day-to-day operation of the case to his trusted friend from law school, assistant US Attorney John, bottomly.

And bottomly brings a completely different mindset.

He really does.

Bottomly looks at the situation and decides they don't need more cops.

They need different brains.

So he builds a task force comprised of psychiatrists, forensic academics, sociologists, and outside researchers.

Imagine the reaction in those precinct houses.

Only must have lost their minds.

Completely.

To the veteran Boston police detectives who prided themselves on traditional shoe leather detective work, hitting the pavement, shaking down informants, trusting their gut bringing in a panel of academics with elbow patches to theorize about the killer's mother complex felt like a massive slap in the face.

Right.

You thought it was useless.

It was viewed as academic elitism encroaching on the gritty reality of blood and guts police work.

But John bottomly had a vision that went far beyond psychiatric profiling.

And this is the part of the research that absolutely fascinates me.

The technological leap.

Yes.

He certainly walks into the command center and looks at the literal mountains of unorganized paper.

Thousands of suspect interviews, witness statements, alabies.

And he realizes that human cognition simply cannot process the data fast enough.

It's mathematically impossible for a human.

Right.

So he introduces early computer science to the hunt.

It is an absolute watershed moment.

It is the genesis of modern cyber policing and data driven profiling.

So cool.

And next bottomly, tracking a serial killer admit pinning index cards to court boards and connecting them with red string.

Bottomly decides to take every single piece of evidence, every variable and feed it into a machine to mathematically hunt for correlations.

I really want you the listener to visualize what this means in 1964.

We aren't talking about opening an Excel spreadsheet on a laptop.

Get on it even close.

We are talking about giant, room sized mainframe computers that have less processing power

than a modern musical greeting card.

Yeah, they were massive and incredibly slow by today's standards.

They used IBM punch cards.

So if a suspect was left-handed,

a researcher literally punched hole number 42 on a cardboard card.

If the suspect owned a green jacket, they punched hole 17.

It was so manual.

Very manual.

They would load thousands of these cards into the mainframe,

which would run them through physical light sensors.

If the light shined through both holes simultaneously,

the machine dropped the card and boom,

you had a suspect who was left-handed with a green jacket.

It was agonizingly tedious work.

Yeah, but it allowed them to cross-reference data points

at a speed that human eyes just couldn't match.

And it forced law enforcement to undergo a massive paradigm shift.

They had to stop looking at crimes merely as isolated physical events

and start looking at them as data sets.

Right, seeing the matrix.

Exactly.

If an offender operates within a pattern,

a computer using Boolean logic is infinitely better

equipped to recognize the mathematical structure of that pattern

than a tire detective on our 40 of a shift.

But, okay, I have to play devil's advocate here.

Oh, for it.

Was the Boston PD's resistance to this purely driven by bruised egos and racism?

Or did they have a valid philosophical point?

That's a really fair question.

Like, are we sure the computer actually helped?

Or did it just create a false sense of mathematical certainty?

Does a giant calculating machine actually translate

to the chaotic reality of the streets?

It's a deeply nuanced conflict.

The ego and cultural resistance were undeniably massive factors,

but their philosophical objection was not entirely baseless.

Okay, how so?

Well, a mainframe computer can efficiently tell you

that 80% of the attacks happened on a Tuesday.

A psychiatrist on the task force can theorize

that the killer has deep-seated misogyny stemming from childhood.

Sure.

But neither of those abstract conclusions

physically puts handcuffs on a suspect.

Right, that makes sense.

The beat cops felt that while bottomless high-tech task force

was busy chasing a theoretical phantom inside a machine,

they were completely losing touch with the physical reality of the city.

And the darkest irony of this entire saga

is that the beat cops were right.

They absolutely were.

While the high-tech task force is busy feeding cardboard punch cards into a mainframe,

trying to build a digital profile of the strangler,

a very tangible physical predator

is literally walking right to the front doors of Boston apartments in broad daylight.

Exactly.

While the entire city's focus and all the media oxygen

is consumed by the strangler,

a parallel string of horrifying crimes

is occurring right under their noses.

It's terrifying.

A rash of brutal sexual assaults

is sweeping the Boston area where

crucially, the victims are not murdered.

And the modus operandi this guy uses

is the skeleton key that completely solves the locked room mystery

from the slurser's case and all the others.

Yes, the handyman ruse.

Surviving victims are reporting a nearly identical scenario.

A man comes to their door in the middle of the day.

He's dressed casually bit cleanly in green work clothes.

Yeah.

And he claims to be a handyman sent by the building's landlord or management company.

It's a con, a brilliantly simple, devastatingly effective social con.

It really is the weaponization of trust.

In one of the attacks, a woman opens her door

to a man in a green uniform who says he's there to inspect a leaky pipe in the bathroom.

Right.

She lets him in.

He follows her to the bathroom,

physically assaults her and then flees the apartment.

He's horrible.

But here is where his hubris finally catches up with him.

A few days later, this exact same man

knocks on the door of another apartment building.

But this time, the woman on the other side of the door refuses to unchain it.

She trusts her gut.

She does.

She tells him to go away.

He gets visibly frustrated.

He storms out of the building.

And because he's operating in the middle of the day and causing a scene,

he is spotted by half a dozen different witnesses on the street.

And those witnesses provide a description sharp enough

that local police are finally able to identify and apprehend a 33-year-old factory worker

named Albert DeSalvo.

Finally, a break.

Yes.

They bring him into the precinct solely for questioning regarding these green man sexual assaults.

We really need to pause and examine the terrifying psychology of his entry method,

though, because it affects every single one of us.

Oh, absolutely.

It's universally applicable.

He exploited our fundamental reliance on cognitive shortcuts.

If someone knocks on your door wearing a utility uniform and speaks with the

board authority of someone just doing their job like,

management sent me to check the radiators.

Our default societal setting is compliance.

We're conditioned to cooperate.

We want to be polite.

We want our radiators fixed.

Think about the last time a maintenance worker knocked on your door.

You probably let them in without a second thought.

I know I have.

That innate,

neighborly trust is exactly what this predator hijacked.

He understood that perceived authority and utility override caution.

And consider the psychological fallout for the city once this method became public.

Oh, the paranoia.

Exactly.

What happens to the fabric of a community when the incredibly mundane act of answering your door

at 2.20 PM on a Tuesday becomes a life or death gamble.

It ruins everything.

It introduces a permanent paranoia into the domestic space.

You can no longer trust your own eyes.

A uniform is no longer a symbol of help.

It's a potential threat.

But here is the massive glaring contradiction that throws the entire narrative into a spin.

A behavioral anomaly.

Right.

Researcher Natalia points out beautifully in her analysis the case files.

DeSalvo is captured and identified as the green man rapist.

But the high-tech task force immediately starts wondering,

could the green man also be our Boston strangler?

It's a natural leap for them to make.

But if he is, it raises a massive red flag.

Why would a ruthless, organized serial killer who has already brutally murdered

over a dozen women suddenly start leaving his victims alive?

That is the great anomaly that continues to fuel debate today.

It just doesn't make sense.

In behavioral science and predatory profiling,

violent offenders operate on a curve of escalation.

They might start with voyeurism, graduate to sexual assault,

and eventually cross the threshold into murder

as they require increasingly extreme stimuli

to satisfy their compulsions.

They don't dial it back.

Exactly.

For an offender to routinely murder,

to take the time to pose the bodies and tie decorative bows

and then suddenly de-escalate back to mere assaults

and intentionally leave living witnesses who can identify him,

it completely contradicts the established laws

of predatory behavioral evolution.

It's like a Category 5 hurricane suddenly deciding it just wants to fly a kite.

That's exactly it.

The physics of the psychological momentum just don't allow for it.

But what if the murders were just accidents?

Like, he only meant to assault them,

but things got out of hand.

That theory was floated at the time, actually.

But it falls apart when you look at the crime scenes.

Because of the bow.

Because of the bow, an accidental panic strangulation

during an assault is frantic and messy.

Taking the time to fashion a symmetrical bow under the victim's chin

requires post-mortem time and deliberate calm intent.

The murders weren't accidents.

They were the goal.

Wow.

Which makes the sudden shift to leaving the green man victims alive so baffling.

Baffling are not capturing the man in the green uniform was one thing.

But when John Bottomley and the psychiatrist started digging into

Albert DeSalvo's past to see if he possessed the specific

terrifying architecture required to be the strangler,

they uncovered a history of trauma that shocked even the most hardened

experts on the task force.

DeSalvo is transferred to Bridgewater State Hospital for a comprehensive

psychiatric evaluation.

And the deeper the psychiatrist probe into his formative years,

the more the pieces of a classic,

albeit horrifying behavioral puzzles start to walk into place.

The abuse in his childhood is staggering.

It's difficult to even read the transcripts.

It's incredibly dark.

During these evaluations,

it comes out that DeSalvo was viciously,

repeatedly beaten by his father.

He vividly recalled,

witnessing his father break his mother's fingers one by one.

Just horrifying.

And most disturbingly,

he claimed his father would frequently bring prostitutes into their small home

and violently have sex with them right in front of the children.

If we evaluate that through the lens of modern criminal psychology,

severe compounding childhood trauma is an incredibly

common foundation in the profiles of violent sexual offenders.

It lays the groundwork.

It does.

Witnessing extreme domestic violence,

specifically violence perpetrated by a patriarchal figure,

severely fractures the developing psyche.

It teaches the child that physical violence is the primary currency of control.

And in DeSalvo's specific case,

witnessing his father abuse sex workers intrinsically linked violence,

degradation, and sexual rousal in his formative neural pathways.

He was taught that sex and violence are completely inseparable.

Bottomly, sensing he finally has his man,

steps in and personally conducts a grueling series of intensive interviews

with DeSalvo at Bridgewater.

He really zeroes in on him.

Now at first, DeSalvo is surprisingly candid about his life as a criminal.

He freely admits to hundreds, literally hundreds of break-ins

and sexual assaults operating as the green man.

He was very open about those.

But when bottomly pushes him on the murders,

DeSalvo vehemently denies killing anyone.

But during the standoff, a very interesting,

highly circumstantial piece of data emerges.

Oh, I know where you're going with this.

While Albert DeSalvo is locked securely inside the walls of Bridgewater State Hospital,

the strangulations completely stop.

Just abruptly end.

The phantom disappears.

No other women in Boston are killed in that manner.

Which is exactly the kind of circumstantial coincidence

that makes desperate police departments and terrified politicians very, very hopeful.

Oh, they were thrilled.

The public finally starts to sleep a little better.

But the prosecutors know they can't take a timeline pause to a jury.

They need more.

They need a confession.

And then, in the summer of 1966, the damn finally breaks.

During another session with bottomly,

DeSalvo suddenly confesses.

And it isn't just a partial confession.

He confesses to the 11 known canonical Boston Strangler murders.

But then he goes even further, right?

He does. He provides a stunning surplus.

He confesses to two additional previously unsolved killings

that the police hadn't even definitively linked to the Strangler yet.

The murder of 80-year-old Mary Mullin in June of 1962,

and 69-year-old Mary Brown in March of 1963.

Wow.

He delivers a perfectly tidy confession to a total of 13 murders.

I have to push back on this narrative, though.

Okay. What do you think?

We talked extensively about his horrific childhood trauma

and how it wired him for violence.

But does severe trauma guarantee a monster is made?

Or does it just set the stage?

That's the big question.

Because from where I'm sitting, looking at the historical record,

this sudden, sweeping confession to bottomly feels incredibly,

I don't know, convenient.

You are hitting on the crux of the entire historical

and legal debate surrounding the Boston Strangler.

Yes, trauma sets the stage.

It absolutely does not guarantee the outcome.

Millions of people suffer unimaginable abuse

and never emit a single crime.

Right.

But your instinct about the convenience of confession

is exactly why this case remain so fiercely debated

among experts today.

Because here is the massive, unavoidable, glaring red flag.

What is it?

Despite this incredibly detailed, sweeping confession to 13 murders,

there was absolutely zero physical evidence

that conclusively linked Albert DeSalvo to the Strangler crime scenes.

Wait, nothing, not a single fingerprint.

Nothing.

Obviously, we are in the pre-DNA era,

but there were no definitive blood typing matches,

no fibers, no shoe prints,

no fingerprints that placed him in those rooms.

That is wild.

The entire foundation of the case was his word to John bottomly.

And yet bottomly and the task force decide

that his word is enough.

They took a win.

They have the confession.

The computer models don't matter anymore.

They officially announce to the press

that the Boston Strangler has finally been caught.

And the city just excels.

The city throws a collective parade.

The hardware store stops selling out of dead bolts.

The long, suffocating nightmare is declared over.

But was it really?

This is where we have to ask you, the listener,

to consider the deeply flawed nature of the justice

sisters' reliance on confessions,

especially in the era before forensic science

could definitively corroborate them.

Right, because people confess to things

they didn't do all the time.

Exactly.

We know today through the exhaustive work of organizations

like the Innocence Project that false confessions

are shockingly terrifyingly common.

Why do they happen?

They can be coerced through exhaustion

or they can be willingly offered

by a deeply mentally unwell individual

who is seeking infamy, attention,

or maybe even just better living conditions in custody.

And DeSalvo was undeniably mentally unwell.

The transcripts show he absolutely reveled in the attention

he was getting from bottomly

and this team of prestigious psychiatrists.

He loved the spotlight.

He was a nobody factory worker

who suddenly had the most powerful men

in the state hanging on his every word.

Exactly.

You have a highly suggestible, deeply traumatized man

with a documented history of sexual violence

who clearly enjoys being the center of attention.

It's a dangerous mix.

Combine that volatile psychology

with a police force, an attorney general,

and a political establishment

that are all absolutely desperate for closure

to save their careers and calm the public.

It is a perfect recipe

for a profoundly flawed resolution.

Did bottomly, intentionally feed him

details of the crime scenes

to secure the confession?

Many historians suspect he did, even subconsciously.

It's incredibly unsettling when you step back

and look at the massive scope

of what we've unpacked today on thrilling threads.

It really is a massive story.

We started this analysis

looking at the jarring innocent visual

of fresh baked muffins

in Anna's Loser's apartment,

completely contradicting the violence around it.

Such a haunting image.

We moved through the sweltering,

oppressive, claustrophobic panic

of the 1962 heat wave.

We saw the revolutionary,

albeit incredibly clunky,

introduction of mainframe computers

and punch cards to law enforcement

to hunt a digital phantom.

Which changed policing forever?

And we confronted the chilling reality

of the handyman ruse,

the predator who bypassed every lock,

simply by asking nicely.

We covered massive ground today,

tracking the painful evolution

of investigative methodology

alongside the darkest,

most fractured corners of behavioral psychology.

But we are left with a haunting consideration

that is simply not fully resolved

by the historical record we examined.

No, it's still an open question in many ways.

In a case that was ultimately built

entirely on a verbal confession

with absolutely zero physical evidence

linking the suspect to the dead,

and knowing that Albert D'Solvo

left his later green man victims alive,

which devise everything we know

about how serial killers evolved,

did the high-tech computer-driven task force

truly catch the Boston Strangler?

Or did they simply lock away a very bad,

very damaged rapist

who was willing to wear the terrifying mask

of the Strangler just to give a panic city

its peace of mind?

That is the million dollar question.

And that leaves us with one final

broader reality to consider.

Regardless of whether D'Solvo acted alone

or if the real Strangler slipped away,

the legacy of this case

fundamentally altered the architecture

of American society.

How so?

Before 1962, the concept of a woman

living alone in a city apartment

was becoming a symbol of newfound independence.

The Strangler case weaponized that independence.

It ushered in the era of the deadbolt,

the people, and the chainlock.

Wow.

It permanently changed how we build our apartments

and how we view our neighbors.

The Strangler didn't just kill women,

he killed a very specific era of urban innocence.

The architecture of paranoia.

That is incredibly profound.

It really makes you look at your own front door differently.

It definitely does.

What do you think about today's discussion?

Does the psychological profile of D'Solvo's trauma

and the sheer volume of his confession

convince he was the sole monster haunting Boston?

Or do the glaring inconsistencies

like the lack of physical evidence,

the impossible de-escalation of violence

suggest the real Strangler might have vanished into history

while everyone was busy staring at the green man?

So lot to ponder.

It is.
