of the Lindbergh baby?

[dramatic orchestral music]

♪ ♪

Hopewell, New Jersey, 1932...

for the past year,

world-famous aviator Charles Lindbergh

has called this area home.

- So Lindbergh has been a major celebrity

ever since he completed

his first transatlantic solo flight in 1927.

- In the drizzly, early morning of May 20, 1927,

the "Spirt of St. Louis" takes off

from Roosevelt Field in Long Island.

And after 33 1/2 hours of flying alone,

Lindbergh lands at Le Bourget Field

outside of Paris.

- Does Lindbergh do something that no one else

has ever done before?

Absolutely. He flies across the Atlantic Ocean

by himself, solo,

on a flight pattern that takes him 2,000 miles

farther than the last transatlantic flight--

a flight, by the way, which had two aviators,

not one.

- Lindbergh's flight proved that aviation had a future

for passenger transportation.

- This also earns Lindbergh

tons of accolades, tons of awards--

everything from the Medal of Honor,

the Flying Cross, a Congressional Gold Medal.

- But there's no way Lindbergh would've reached this level

of fame and adulation without one thing--

radio.

[radio crackling]

- You have to understand-- at the time,

no smartphones, no Internet, no television.

This is before almost any form of modern communication.

Radio is revolutionizing the way the world connects.

So, when Lindbergh is making this record-breaking flight,

this is the first time that an audience

can actually follow along with an historic event

in real time.

- This is a moment of instantaneous information,

not the delayed information we get in newsreel

or a newspaper account or a book.

This is happening in real time,

and that's very impactful for people.

After this flight, he comes back home.

There's a ticker-tape parade--

hundreds of thousands of people.

He gets millions of telegrams congratulating him.

Lindbergh is instantly internationally famous.

- But before long, the intensity

of this public adulation becomes overwhelming.

[cheers and applause]

- Lindbergh is badgered constantly by the press.

Everybody wants a piece of him.

- Charles Lindbergh and his wife decided

we've had enough of being in this crazy public eye,

so they bought some land in Hopewell, New Jersey.

- They purchase a remote 600-acre lot,

where they plan to build an estate

that will be their primary home,

along with their 20-month-old son, Charles, Jr.

- Construction on their new home begins

in March of 1931, but the Lindberghs

are just so anxious and so ready to leave New York

that they decide to head out to the house

before it's even completed,

and they start staying there a few days a week.

In addition to Charles, Anne, and Charles Jr.,

they've got the nursemaid, Betty Gow,

their butler, Olly Whatley, and his wife, Elsie,

living in the house with them.

They're a pretty tight-knit group.

- Lindbergh increasingly resents

the intrusions on his private life.

The purpose of the construction

of the estate outside of Hopewell

was to give the Lindberghs some breathing room

from the 24-7 press attention that the family is under.

- But before the Lindberghs find their respite,

on March 1, 1932, the unthinkable happens.

- So, shortly before 10:00, the nurse, Betty Gow,

heads into the nursery to check on Charles Jr.

[door creaking]

- She is horrified to find out that the crib is empty.

She runs to tell Lindbergh.

He follows her back to Charles Jr.'s room,

and he finds out that she's right.

The baby is gone.

- The house staff immediately begin searching the property.

- They are combing the house high and low,

and while they're searching, Charles Lindbergh comes

across something that confirms his deepest, darkest fears.

Near the window of his son's room,

he finds an envelope.

♪ ♪

There's a problem with this particular window.

It's warped, which means that it doesn't close properly.

The latch doesn't actually catch,

so this is the only way

that you could get into the house without a key.

- This was a second-floor window.

This wasn't one you could just

walk up to the house and climb through.

- In the envelope

is a poorly written, misspelled note

demanding $50,000 for the return of the baby.

It's a ransom note.

♪ ♪

The note reads, "Dear, sir, have $50,000 ready.

"$25,000 in $20 bills,

"$15,000 in $10 bills, and $10,000 in $5 bills.

"After two to four days,

"we will inform you where to deliver the money.

"We warn you from making anything public

"or notifying the police.

The child is in good care."

- At the bottom of the note,

the kidnappers leave a cryptic signature.

♪ ♪

- They had an image at the bottom

that was two interlocking circles,

couple of squiggly lines,

and then three punch holes.

It's a very strange pattern.

- So the author of the letter actually says

this particular symbol will let you know

that this is authentic correspondence

from me and no one else.

- As if this is some sort of secret code

to verify that the letters are genuine

and that, rather chillingly,

more letters may follow.

- It was as if the kidnappers were saying,

"This is just the beginning."

- As they comb the property,

Lindbergh and his butler, Olly,

find a few additional clues.

- There are also some scraps of wood from a broken ladder

underneath the window,

and they also find a set of muddy footprints.

- By 10:30 p.m.,

a small army of police officers arrive

and begin investigating.

- The police realize they have very little to go on.

They've got no fingerprints.

They've got no eyewitnesses.

- And you're in the middle of nowhere, really,

at a massive estate.

So, when it comes to this investigation,

where would you want to start?

On the inside, of course.

[tense music]

It's only natural to start with those

that are closest to the crime, and based on the circumstances,

there are signs that may have indicated

that this could've been an inside job.

First off, the precision of this kidnapping

and how it went down is a bit suspect.

It's as if the person or persons

knew exactly where to go, but how?

Based on the scene outside,

the footprints, the wood from the broken ladder,

it appears that whoever took Charles Jr.

went to one window only,

the window that led directly into the nursery.

We also know that Charles and Anne were awake

at the time of the kidnapping, so there's no way

that there's gonna be somebody outside of the property

moving a ladder from window to window trying to jimmy open

every window before they find the correct one.

They would've been heard.

- There's a dog. The dog doesn't bark.

There's a baby.

Babies cry, but this baby did not cry.

So there's a general sense that there must be someone

who's familiar with the household--

has to be involved.

- The nursery's condition is also suspicious.

- The baby's blankets after Charles Jr. is taken--

they're not just left in the crib.

They're actually folded very neatly

and placed on a shelf nearby.

Why would a stranger that's kidnapping

Charles Lindbergh's baby even bother to do that?

That seems more like a routine

of somebody that's in the house

that does this frequently.

- Authorities figured that the kidnapper

had to have had inside knowledge of the schedule.

- The Lindberghs are creatures of habit.

They do not go to the house in the country all the time.

Normally they're there on the weekend,

and they leave on Monday.

But Charles Jr. got taken on March 1st,

which was a Tuesday.

- They stayed one extra day at the home

because the baby had a cold, and so they thought

that the country air, the fresh air,

would be good for the baby.

- And the question becomes,

how would a random person know that?

- So, if you're looking at this as an inside job,

your first three suspects should be obvious.

The Lindberghs' staff members--

you've got Betty Gow,

you've got the butler, Olly,

and his wife, Elsie Whatley.

The Whatleys had been with the Lindberghs

all weekend long, so they pretty much have alibis.

Olly was actually in bed, and Elsie was downstairs

in the kitchen making lemonade.

- But nursemaid Betty Gow

has only arrived that afternoon.

- Does she have time to plan a kidnapping?

The police question her immediately.

- According to Betty's statement on March 1st,

Anne calls Betty and asks her to come to the weekend estate,

and Betty agrees, even though she had plans

at the time with her boyfriend,

Henry "Red" Johnson.

Betty says that she called her boyfriend

to cancel her plans because she had to go into work.

Police question Johnson,

and he backs up his girlfriend's story.

However, in Johnson's car, they do find a bottle of milk.

- This bottle of milk was really suspicious to police.

They wondered, you know, is that there to feed a baby?

- There are some theorists that suggest

that when Betty Gow called her boyfriend

to cancel the plans, that's not actually what she was doing.

She was actually calling him to signal to him

that, yes, he should kidnap the baby.

- Apart from a bottle of milk,

police have no evidence that implicates Johnson

or Betty Gow.

- Lindbergh intervenes to prevent the police

from really interrogating and bearing down

on the servants in his own household,

who he trusted without qualification.

- And that meant that Betty Gow

wasn't looked at any further.

That line of inquiry goes cold, but then they find another.

[dramatic music]

- When famed aviator Charles Lindbergh's

infant son is kidnapped on March 1, 1932,

it creates an unprecedented media uproar.

[crowd clamoring]

- It's a cliché nowadays to call something

a crime of the century, but this really was.

This was one of the biggest cases,

not just in America, but in the world.

- We have here a flash which reads as follows...

- News of the kidnapping leaks almost immediately,

and journalists just flock to the Lindbergh estate.

It's a madhouse.

- Of course, everybody wants to help.

One of the people who wants

to provide criminal expertise to this case

is the notorious gangster Al Capone,

who--currently residing in the Cook County Jail.

He offers his criminal and gangster contacts

to help the police find the Lindbergh baby

if they will just temporarily release him from prison.

The police do not take Al Capone up on his offer.

♪ ♪

- That was indicative of just how widespread

this story had gotten.

It was reaching everybody.

- Al Capone, sitting in a cell in Chicago,

finds out about this news only 12 hours after it happens.

Mind you, there is no Internet during this time.

But let's also remember--

the ransom note specifically said

do not make this a public deal.

Do not get the police involved.

- Is all the media attention

jeopardizing the life of the child?

- The Lindberghs soon learn the answer to that question.

- So, on March 6th, another ransom note arrives.

- And it follows the pattern of the first ransom note.

You've got the same handwriting.

You've got the same signature with the squiggly lines.

And you've got the three holes, but the tone of this letter

is much more threatening.

- And it starts off by saying,

"Dear, sir, we've warned you not to make anything public."

- "Now you have to take consequences."

And the consequences are severe.

The kidnappers basically say

that they're going to keep the baby

until things quiet down.

As long as this case continues to get as much attention

as it's getting from the police and the media

and the newspapers,

Lindbergh is not getting his son back anytime soon.

- Because of that transgression,

the kidnappers now have decided

that instead of a $50,000 ransom,

they want a $70,000 ransom.

- 70 grand back then is like a million dollars today.

- So they don't actually wait until things die down.

In fact, the story continues to get bigger and bigger

as it goes on.

But regardless, within a couple of days,

the kidnappers carry on with their plan.

In a series of notes that were sent both on March 8th

and March 10th, the kidnappers

are asking for a volunteer to serve as the go-between

for the handoff of the money.

Ultimately, they agree to let a former school principal

from the Bronx be that volunteer.

And his name is Dr. John Condon.

So probably seeking some fame for himself,

Condon placed an ad in his local paper

offering up $1,000 reward

if the kidnappers were to give up the baby to a priest.

Apparently the kidnappers saw this ad,

asked him to be the middleman,

and he agreed to do it.

And at this point, the police have so few leads

that they decide, "Go with it.

Why not? Let's see how this plays out."

- With the support of the Lindberghs and police,

Condon begins corresponding with the kidnappers.

- So, over the course of two weeks,

there is a chain of back-and-forth,

this, like, cat-and-mouse game.

Condon would put ads in the local paper,

and the kidnappers would respond with their letters.

And this back-and-forth keeps the Lindberghs hopeful

that their son is still alive and a solution will be reached

where they'll be able to get him back.

They eventually arrange a meeting between Condon

and the kidnappers at a cemetery in the Bronx.

- According to Condon, at this meeting,

he finally learns the kidnapper's identity.

♪ ♪

- Condon says he meets a man who calls himself John,

whom the media and the police will soon dub "Cemetery John."

- Cemetery John tells Condon he's part of a group

of Scandinavian sailors.

The baby is being taken care of by these sailors on a boat.

- He says the baby is safe and that we need

to make an exchange for the ransom money.

- This Cemetery John is about 30 to 35 years old,

athletic build, 5'9".

Based on Condon's description, police prepare a sketch

of Cemetery John.

He has a light complexion, light hair,

pointed chin, and he has a Scandinavian accent.

Meanwhile, during the meeting,

Condon wisely asks the kidnappers

for proof that they have the baby.

- On March 16th, Condon receives that proof.

- Cemetery John promises to send some evidence.

What turns up at Condon's house

is a gray sleeping suit

that Charles Jr. was sleeping in

the night he was taken.

- From here, you've got a number of things

that are happening in quick succession.

There are several more exchanges

between Condon and the kidnappers,

trying to haggle over what the actual ransom should be.

- Condon and the kidnappers ultimately agree

on the original $50,000 ransom amount.

- Police decide to use gold certificates

to pay the ransom.

This is actually a clever move by the authorities,

because here's the thing-- those gold certificates

have the same value as dollars, but for the past 70 years,

the United States had tied its currency to what was,

at the time, the gold standard.

They were a legal tender of money,

but they were a bit more unique.

The idea that the police had was,

if they pay up the ransom in these certificates,

because there's so few of them in circulation now,

if they're spent, they're easier to track down.

But that whole plan will have to come later.

Right now the Lindberghs only care

about getting their baby back,

and they firmly believe that tonight is the night

that it happens.

- On April 2, 1932,

John Condon goes to do the money exchange

to the kidnapper.

At the exchange, the kidnapper gives

John Condon a letter and then disappears with the money.

The letter says that the boy's on a boat called the "Nelly."

The "Nelly" is a small boat, about 28 foot.

It has two women on it, who apparently know nothing.

They've just simply been hired to watch a baby.

And you can find this boat between Horseneck Beach

and Gay Head near Elizabeth Island.

♪ ♪

- And when Condon shares this information,

police race off to this marina

at Martha's Vineyard to find this boat,

because you have to understand--

these cops are trying to get there as quickly as possible,

because think about it--if you're the first police officer

to find Charles Lindbergh's kidnapped baby,

it's like your guaranteed to be a hero.

Police get to this marina, and they search every slip,

every boat.

"Nelly" is never found,

and the baby Lindbergh is never found.

♪ ♪

- The thing about this Scandinavian gang theory

and all this is, they're assuming

that we're gonna get the baby back,

and that's not what happened.

And this really sets a new tone, I think,

in relation to this whole experience,

'cause people now are really more concerned

on some level about the fate of Charles Jr.

- With their ransom paid,

there is no further communication

from the alleged kidnappers.

- The kidnapper has the money,

but the Lindberghs do not have the baby.

in Mount Rose, New Jersey, which is a little less

than five miles away from the Lindbergh estate.

- William Allen was a Black man

who worked as a trucker.

One of the disgusting parts of American history

is that he wasn't allowed to use the bathroom

wherever he wanted.

So he pulled over to use the restroom in the woods.

He walked in a ways,

so as not to be spotted by anybody passing by,

At first, he assumes it's a dead animal.

But as he gets closer, he realizes it's a small child.

and animals are starting to scatter the remains.

All that is really left is a tattered white T-shirt.

Betty Gow, to identify the body.

♪ ♪

- A funeral director conducts a rudimentary autopsy

and declares that this child died from a blow to the head.

- This funeral director establishes that the baby

died probably two months ago.

That time line means that much of the time

that these notes were being exchanged

around returning the baby,

he was most likely already dead.

- Grieving parents Charles and Anne

have their son cremated.

And the investigation turns from kidnapping to murder.

- So, naturally, this marks a huge shift for police,

because if this child died the very night

that he was kidnapped,

well, this puts them back at square one.

And in this case,

square one means that maybe their initial instinct

was right all along.

Maybe this was an inside job.

[ominous music]

- In May of 1932,

the case of missing infant Charles Lindbergh Jr.

turns from kidnapping to murder.

- The police were confident

a man named Cemetery John was involved.

He and a group of accomplices send ransom demands

and eventually collect $50,000.

Once they pay the ransom, Cemetery John is gone,

and they find the body of Charles Jr.

and find out that he apparently died

the very night he was taken.

- With no new leads, police focus their attention

on the Lindberghs' extended family.

- The lingering question is why baby Lindbergh

was targeted at all,

and why on a Tuesday,

when the Lindberghs were not usually there?

And how did the kidnapper know which window to enter?

As the investigators work through a long list

of Lindbergh family and friends and associates,

eventually they find someone

whose story doesn't quite add up.

And they jump at the chance to label her a suspect.

♪ ♪

- New Jersey State Police question a domestic worker

named Violet Sharpe.

- Sharpe is a 20-something immigrant from England,

who works for Anne's mother at her house,

serving her meals, which means that she's working

for the baby's grandmother.

- So the minute they begin questioning her,

Violet becomes very nervous.

She doesn't want to answer questions.

Sometimes she's a little belligerent.

♪ ♪

It's obvious to the officers that she is being evasive.

But why?

- And her story keeps changing.

At first, she says that she's on a blind date

on the night of the kidnapping, but she can't remember the name

of her date or the other couple that she was with.

- She claims she went to a movie,

but she can't remember which one.

And later, she claims she went to a roadhouse

and not a movie at all.

- So the police decide that they need to take

a closer look at Miss Sharpe,

so they ask her for all of her bank statements

and all of her financial records

to see if there have been any large deposits

that've been made.

They also ask her to come in and to give an official account

of her whereabouts during the day of the kidnapping.

- They're pushing so hard because they're convinced

that Violet Sharpe must know something.

- So the police schedule several interviews

with Violet Sharpe.

And the last one, she just doesn't turn up to.

- And they start to think, "Is she on the run?

Did something spook her? Where is she at?"

Sadly, on June 10th,

one month after baby Lindbergh's body's discovered,

Miss Sharpe's body is also discovered.

She had ended up committing suicide

by eating silver polish.

And, ultimately, after her death,

investigators are actually able to prove her alibi

for the night of March 1st.

Turns out, she was on a date after all.

is questioned and discarded as a suspect--

everyone, that is, except for one,

Charles Lindbergh himself.

- Today when we have any kind of crime

involving a child or a family,

In 1932, no one is going to question Lindbergh

could have anything to do with an exploit so sociopathic

as the kidnapping of his own son.

- One of the things that happens over time

is that people thinking about the crime

start to notice odd things about Lindbergh's behavior.

Theories start to emerge that perhaps Lindbergh

is involved in some way.

over the investigators that were involved in this case.

In fact, according to one story,

when the police arrived at his home,

Lindbergh is standing outside with a rifle,

"If anyone disobeys me, they're going to get shot."

is a one-page account where he can't really attest

to his own whereabouts the day before the event.

Lindbergh has very strong connections

to the New Jersey State Police,

and it's documented that he wanted them to be in charge.

Some say that Lindbergh wants control of the investigation.

Lindbergh kidnapped his baby once before.

Just a week earlier, Lindbergh hid the baby in a closet,

the next day explaining what had happened.

In eugenics, scientists, what they do is,

things like rickets.

His legs bowed.

He didn't have a whole lot of strength in his lower body.

He seemed to be a little slow on development in that area.

It didn't seem as though Charles Jr. fit the mold

As soon as investigators connect the bill to Hauptmann,

they immediately put him under constant surveillance,

hoping that he'll slip up and incriminate himself.

At some point,

Hauptmann realizes that he's being watched.

Now, maybe he knows he's guilty,

or maybe he's worried about his status in the United States.

Either way, he decides to jump in his car

and make a break for it.

[sirens wailing]

- And it's a straight-ahead gangster-film chase,

riding through the streets.

Police cars after him,

running through traffic.

It's something right out of a movie.

He's finally pinned in on Park Avenue in the Bronx.

♪ ♪

Hauptmann is arrested,

and authorities begin a search of his car

and his house.

♪ ♪

They're searching through all his belongings,

not finding much of interest,

until they look inside this old garage

at the edge of the property.

- There, in a stack of old gas cans,

police finally find their smoking gun.

- They open some jars, and what do they find?

$14,600 in gold certificates.

- And once they find the cans of ransom money

in Hauptmann's garage,

it's a race to the finish to build a case against him.

And the evidence is pretty damming.

- Detectives check the serial numbers

on every bill found at Hauptmann's place.

And indeed, these are the certificates

that were given as part of the ransom.

- In Hauptmann's attic, there is more evidence.

- Remember, the night Charles Jr. goes missing,

they find those broken pieces of wood

underneath the nursery window that'd come from a ladder.

Well, in Hauptmann's attic, they find a ladder.

♪ ♪

- Not just any ladder--

a handmade telescopic ladder

designed to collapse in on itself.

This allows one person to carry it easily,

while being long enough to reach the height

of Lindbergh's second-story window.

♪ ♪

- Was it the ladder used to kidnap the Lindbergh baby?

Hauptmann is a carpenter, and so he has his own tools.

He has the ability to build the ladder.

- And during the attic search,

investigators find a section of floorboard

that had been cut.

♪ ♪

- A team of experts study the wood from the floorboards

and forensically compare it to the wood from the ladder.

- And this gets them thinking.

The wood grain in one rail of the ladder,

dubbed "Rail 16" seems to match up perfectly

with that cut section from Hauptmann's attic floor.

And the nail holes also match the nails

used to construct the attic.

So experts are convinced that the ladder is made

from slats in the floor of Hauptmann's attic.

♪ ♪

- But police need more for a conviction.

[camera shutter clicking]

- Of course, owning a ladder isn't a crime.

But then investigators find one more clue.

♪ ♪

- They found a phone number written on the wall

in the closet in the kitchen.

Whose phone number was it?

- Dr. John Condon,

the same man who was the intermediary

for the ransom handoff.

Finally, investigators commission

handwriting analysis between Hauptmann's handwriting

and the writing that appeared on the ransom notes,

and they find multiple similarities.

- Both sets of writing contained backward Ns,

curls on the Ys.

Additionally, he spelled some of the same words wrong.

♪ ♪

- On September 24th,

Hauptmann is indicted for extorting

the $50,000 ransom from Charles Lindbergh.

Shortly after, on October 8th,

he's also indicted for the murder

of Charles Lindbergh Jr.

[camera shutter clicking]

♪ ♪

- Hauptmann is represented by Edward J. Riley,

an attorney actually hired

by "The New York Daily Mirror"

for exclusive rights to Hauptmann's story.

♪ ♪

- The trial brought hundreds of reporters

into town.

People couldn't find hotel rooms for miles.

It was huge.

- He quit his job the day he collected the $50,000,

the very day!

- After a conviction and two failed appeals,

Hauptmann is executed by the electric chair

on April 3, 1936.

♪ ♪

- And that's it, everyone. Mystery solved.

We now know the truth of what happened.

Or do we?

- Even after the conviction of Richard Hauptmann

for the murder of Baby Lindbergh,

not everyone's convinced he's solely responsible.

- Obviously, the police want to close this case

as neatly and as efficiently as possible.

And looking at the evidence they have,

Hauptmann appears extremely guilty.

- It seems very likely

that he was involved in these crimes.

- But even the highest authorities wonder,

did he act alone?

♪ ♪

- While Hauptmann is awaiting execution,

the governor of New Jersey himself,

Harold Hoffman, visits him in his cell.

He also brings along

a translator who speaks fluent German.

- While there were no notes released

from this talk,

it seems like it was a pretty influential talk.

- After talking with Hauptmann,

the governor implores court officials

and the police to keep on investigating.

- He ended up granting him a reprieve.

- Governor Hoffman felt that there was more to the story

than what the state had put forward at the trial.

And he wanted to make sure that everyone who was involved

was identified and brought to justice.

- As we know, of course,

that request from the governor isn't followed upon,

and Hauptmann takes the fall

as the one and only perpetrator

of that crime.

Hoffman doesn't give any more reprieves,

and the execution takes place

four years after the kidnapping.

♪ ♪

- For the next six decades,

Hauptmann's guilt is generally accepted,

along with the idea that he acted alone.

Then in 2003,

a state police archivist makes a startling discovery.

Sitting right there in the archive

is a board with a signed confession written on it.

- It's written in German, but it translates to,

"I was one of the kidnappers of Lindbergh's baby,

not Bruno Richard Hauptmann."

It goes on to state that some of the ransom money

was buried in the town of Summit.

♪ ♪

- What's more intriguing still is that there's

a series of screw holes--

like a table leg or a brace was removed

with a large circle around it.

And when a comparison is made to the ransom note,

these holes line up perfectly

with the holes that were found in those ransom notes.

♪ ♪

- The board was apparently reported

to the state police in 1948.

A man found it attached to the bottom of a table

he had recently purchased.

- So authorities did not take this seriously

because there had been dozens of confessions.

Dozens of people had said that they were involved,

in some cases, that they were actually the baby.

♪ ♪

- Handwriting comparisons are made

between Hauptmann's writing and the writing on the wood,

and they don't match.

- If Hauptmann didn't write it, who did?

- In 2012, author Robert Zorn

offers a potential lead on who might have written this note.

- In his book "Cemetery John,"

he reports that his father, Eugene,

may have witnessed Hauptmann conspiring with two other men

in 1932.

Growing up in the South Bronx,

Eugene lived next to a John Knoll.

And one day at an amusement park,

Eugene claims to have seen John Knoll,

along with his younger brother Walter,

and Hauptmann in the amusement park

speaking in hushed tones in German,

plotting something.

He recognized the words "Bruno,"

which was Hauptmann's first name,

and the word "Englewood,"

which was the suburb where Lindbergh's family lived

in New Jersey.

- Zorn puts a few more details together

for this story as well.

John Knoll was a stamp collector,

and the Lindbergh ransom notes

use a variety of odd stamps.

And Knoll's residence on the South Bronx

was along the same Lexington Avenue subway route

of which the ghost certificates were spent.

If you look at the sketch,

Knoll and Cemetery John show a striking resemblance.

- Could John Knoll be the real Cemetery John?

- While this information is revealing and interesting,

at this point, it's impossible to prove

that John Knoll was Cemetery John.

♪ ♪

It's possible they sent the wrong man

to the electric chair,

or there at least two or more accomplices

that never got any attention.

- For a mystery that's supposedly already solved,

there are still a lot of questions

that people have that linger about this case.

- How could this have succeeded

without someone having inside knowledge?

What about the inconsistencies at the crime scene?

♪ ♪

- Why was Dr. Condon so heavily involved?

Did he have something to do with this?

- What about the death of Violet Sharpe?

What about John and Walter Knoll?

- And, of course, the biggest question of all--

could Lindbergh have possibly orchestrated the whole thing?

For now, we're left with the official story...

at least until a new clue appears.

♪ ♪

- As of today, less than 20,000

of the original $50,000 ransom

paid to Cemetery John has been recovered.

If the rest ever turns up, will it tie back to Hauptmann,

or will it point to a new suspect?
