(gunshot bangs)
- [Narrator] A brutal rape and double murder of teens
and dozens of suspects in view
but not one can be substantiated.
- The case goes cold, but it's never forgotten.
- There was some uncertainty for sure
if we would ever solve it.
You should never let these cases go cold.
If there's a chance to solve them,
you need to tell the story.
- [Narrator] One piece of evidence is perfectly preserved.
- And it would take decades for that evidence to be used.
- But there's a new crop of detectives coming up
with new ideas.
- [Narrator] And over 60 years later,
the technology finally catches up.
A terrible mystery that was once hidden from view
is now able to be seen.
- If not for one single sample of DNA,
the murders of these two young people would almost certainly
never have been solved.
- I don't want them to be forgotten.
(intense music)
- The unsolved ones, we have to send up.
- And approach these cases in a way outside the box.
- Let the world know is those out there
that did commit a murder
and there are people that are coming after you.
- There's just a lot of good people
trying to do the right thing.
- Because it's something that you have
to be passionate about.
- Solve this, bring some peace to the family, at least.
Just doing my job.
(intense music)
- [Narrator] From about 1950 to 1970,
Great Falls is Montana's largest city.
- And the Sun River, one of Montana's more picturesque areas
is a tributary of the Missouri River,
18 miles west of Great Falls.
- [Narrator] In this idyllic place,
there are several waterfalls,
famous for trout and mountain whitefish
and excellent boating.
- So 1956, this town was exploding.
There was a bunch of clubs that were popping up,
obviously it was post World War II,
I did talk to a few folks that were alive at that time
and they just described it as a safe community,
a place where you could never imagine
something like this happening.
- [Narrator] The new year has just begun.
Three boys strike out for a morning hike near Wadsworth Park
along the Sun River northwest of Great Falls.
- They hiked down a little used road
just west of the city limits and onto a dirt trail.
- It's best described as a Lover's Lane type area
where teenagers would go at night,
they would cruise that area and kind of a hangout of sorts.
- The boys are brothers, Wayne and Robert Falcon,
and their friend Carl Perenteau,
who's visiting from Dodson.
They'll be going back to school soon.
They wanna make the best of their Christmas holiday
before they return.
- [Narrator] The boys see a parked car between two trees
and a terrifying site.
Partially underneath the vehicle,
there lies a young man in a pool of blood
with an apparent head wound.
- Ominously, his hands are tied behind his back with a belt.
(intense music)
- [Narrator] The boys run to the nearest phone
and call police to the Vineyard Road location
near what is known as Hill 57.
- The police call for an ambulance.
They find the victim's wallet and identification with him.
- [Narrator] The ambulance arrives quickly,
but it's far too late,
the victim is dead and has been so for about 12 hours.
The three boys that found the body while hiking
are questioned and then sent on their way.
(eerie music)
- Young man is identified as 18 year old Lloyd Duane Bogle,
an airman at the nearby Malmstrom Air Force Base.
- Lloyd Duane Bogle is known to have a steady girlfriend
and they're frequently seen in each other's company.
- [Narrator] In fact, they were together the night before
on January 2nd.
- Bogle's girlfriend's name is Patricia Kalitzke.
- [Narrator] Police contact the Kalitzke family.
They learned that their 16 year old daughter
Patricia is missing.
She is last seen in her boyfriend Lloyd Bogle's company.
Upon hearing of Lloyd's murder, the family is frantic.
- [Narrator] The victim's car has its ignition
and headlights on, the emergency brake deployed.
Sheriff's officers thoroughly searched the area for clues
about the killer or any trace of Patricia Kalitzke,
but they find nothing.
- There is $5 in Lloyd Bogle's wallet
and an expensive camera in the car.
So this is clearly not a crime of robbery.
- Obviously they did not have the technology,
they did not have the training,
they didn't document like we do now.
It would've been a difficult scene to investigate.
- Investigators find nothing except a motor-mount bolt
found near Bogle's body
and are unsure if this is related to the crime or not.
- Patricia's parents don't report her missing
until the next night
because they believe the young couple has eloped.
The Kalitzke family is holding out hope
that Patricia's not with Lloyd when the murders occur
or the very least has been kidnapped
and will be found alive later.
(intense music)
- [Narrator] Malmstrom Air Force Base authorities
join police in the investigation.
Lieutenant RM Thomas of the Police Identification Bureau
and Deputy Sheriff Harlan McDonough
also searched the murder location
but find nothing to add to the investigation.
The day after the discovery of Lloyd Bogle's body
at about 01:30 p.m., a county road patrol operator
is grading a county road.
- About five miles north of Mount Royal,
routing notice is a piece of blue cloth
at the bottom of an embankment.
He inspects closer and finds a body.
- And as he looks down this large embankment,
he sees the body of a female.
He goes down, checks on her, she's deceased.
- [Narrator] Officers are notified and speed to the scene.
Of course, what everyone is wondering,
is this the missing Patricia?
- The body is found 300 yards northwest
of the Great Falls Trap and Skeet Club.
Officers discovered that the body down the embankment
is high school student Patricia Kalitzke.
(intense music)
- [Narrator] There is little doubt that these two killings
are related and this is a double murder.
(intense music)
Police examine the scene for clues.
Patricia Kalitzke's body is fully dressed.
She does not appear to have been sexually assaulted
either before or after the murder.
Like Bogle, she has an apparent headwound
that appears to be from a bullet.
- Police discover a trail of blood in the grass.
It looks like she is shot,
dragged to the edge and thrown down the embankment.
(eerie music)
- As far as evidence recovered at that scene,
they did not find a lot.
It appeared to be more like a dump site.
(eerie music)
- Everyone's hopes that finding 16 year old Patricia alive
have been crushed.
Question is who could have hated these two young lovers
enough to kill them?
- Law enforcement had a hard time determining
what the possible motive was at that time.
They weren't sure if they were dealing
with multiple subjects or if they were dealing
with one person.
They really weren't sure what the cause of this was.
- One of the difficulties about this case
is there were many suspicious people in the area.
So a lot of suspects.
- Rumor has it that this was a place
for a lot of people that lived in the Chicago area
that would come out to this area to lay low
if you will.
(eerie music)
- There was a lot of interesting characters
that were in this area and known criminals.
- A lot of known criminals and two dead teenagers.
(intense music)
(eerie music)
- [Narrator] Hikers discover a brutally murdered body
that police quickly identify as 18 year old
Lloyd Duane Bogle,
an airman assigned to Malmstrom Air Force Base.
(intense music)
Police learn that Bogle is last seen with his girlfriend,
Patricia Kalitzke, who is missing.
There is brief hope that somehow Patricia
has lieud the killer but the next day,
her body is found seven miles away
from where her boyfriend Lloyd is murdered.
- People were afraid, obviously,
they knew that there was a murderer on the loose
and people weren't sure how to take it.
People were leaving their doors unlocked,
there wasn't a lot of crime
and now you have two teenagers that are murdered.
- [Narrator] Lloyd Duane Bogle
was born on January 18th, 1937,
in Navarro County, Texas, and lives in Waco, Texas.
He's one brother, Jimmy Bogle.
Bogle has been stationed at the Malmstrom Air Force Base
in Montana since April 16th, 1955,
assigned to the 29th fighter Interceptor Squadron.
- Lloyd is so young that Malmstrom
is likely his first posting since finishing basic training
and technical school, but he's growing up fast.
- [Narrator] While stationed at
he meets Patricia Kalitzke,
the daughter of Mr. And Mrs. Henry Kalitzke.
Patricia is a popular Great Falls High School junior.
- He's described as being smitten with Patricia.
They seem well-suited.
They both like dancing and music.
The young couple feel so well-suited,
they've been discussing marriage so much so,
that their parents fear they might be eloping
and that may have been causing some conflict at home.
- Her family was pretty strict.
She had actually got grounded
because she had stayed out past curfew.
So leading up to the homicide,
that was the first night she had been out in a week.
- [Narrator] On Monday, January 2nd,
the couple go together to a Great Falls drive-in
for a cup of coffee.
- Maybe they're discussing their future life together.
Marriage is definitely in the air.
(somber music)
Later it seems likely they drove to a local Lover's Lane
and that's where their killer came upon them.
(gunshot bangs)
- [Narrator] Police pour over Bogle's car for clues
but nothing is found.
Officers find an abandoned car near the scene
with a bullet hole in it.
But the car has been sold and resold so many times,
no leads come of it.
There is little to go on.
A recommendation is made for an autopsy.
- It's hope that this will produce something
substantial for the police.
These are both execution style murders,
Bogle's hands are tied behind his back
and he's forced to kneel and then shot from behind.
(somber music)
- [Narrator] The coroner finds Bogle is shot in the head
probably between 10:00 p.m. and midnight on Monday
and he's left alive but dies
between two and 04:00 a.m. on Tuesday.
- The bullet enters near the back of the head.
It is unknown if the second hole in Bogle's skull
is caused by an exit or a piece of bone.
The bullet is missing.
(intense music)
- There are indications that Patricia was shot
about an hour after Lloyd
and probably forced to watch the shooting of her boyfriend.
From the scrapes to her body,
it looks like Patricia tried to run through brush
or jump from a car to escape.
But like Lloyd, Patricia is forced to kneel
and is shot in the back of the head.
(gunshot bangs)
(intense music)
- With both victims, the bullet passes through the head
leaving nothing from which ballistic tests can determine
the type of weapon.
Measurements of the bullet holes indicate the gun
to be about a 45 caliber size.
- [Narrator] Authorities know there is a strong possibility
that she was sexually assaulted, but a vaginal swab,
standard procedure for autopsies in 1956,
reveals an even greater shock.
Patricia has not just been sexually assaulted but raped
and a small sperm sample is preserved
on a microscopic slide.
- Newspapers at the time don't say that Patricia was raped
for reasons we can only surmise now.
Perhaps that information was deemed too inappropriate
to put in print at the time
or maybe there was a desire to protect her
or shield the family from the shame of rape
in a small town in the 1950s.
- [Narrator] The coroner's jury deems an investigation
should be continued until such person or persons
be prosecuted by the county attorney's officer,
the full extent of the law.
Two police sergeants, Fred Peres and Jack Anderson,
are permanently assigned to the investigation
under sheriff DJ Leeper's supervision,
Leeper puts every available officer on the case.
- Many law enforcement officers in the area
join in the investigation.
Sheriff's officers with city detectives on loan
carefully follow up on hundreds of tips that are pouring in.
Several people claim to have eyewitness accounts,
but these turn out to be hoaxes.
- Witnesses with false memories or distortions
can truly believe their version of events.
This hoax may be the result of a shocked community
just trying to put this horrible crime behind them.
Police interview Patricia's family and her friends,
but they come up with nothing.
No one can imagine why anyone would kill
these two young people.
- [Narrator] The evening of January 4th,
police pick up and hold a person of interest.
- They found him in the area and he has scratches
on his face.
- [Narrator] The suspect initially says he hurt himself
in a car accident
but under questioning, he says that a woman scratched him
a few days earlier at a party.
Nothing however comes of it.
- Police don't stop there.
They go on to find multiple suspects.
It turns out there are some very dangerous people
in the area.
- [Narrator] Edward Wayne Edwards who was arrested
for burglary in Montana in 1956
and serves time at the Montana State Prison
is investigated as a possible suspect.
- Edwards will later be known as a prolific murderer.
By 1956, he was flying under the radar.
- [Narrator] Air Force Base officials
conduct their own investigation.
They discover a man who argues with Lloyd
just days before the murder.
He is held at the Air Force base.
There's another possible suspect
as police interview a mutual friend of the couple
and remove blood stained shoes and pants
from this person's home for testing with the FBI.
The victim's clothing is also sent for testing.
(intense music)
The motor-mount bolt found near Bogle's body is theorized
to have come from the vehicle of a youth
who dislikes Lloyd Bogle
and is sent to the FBI for examination.
A former Malmstrom Air Force Base airman,
Floyd J. Robertson, 25 who's now in jail,
is interviewed in connection with this crime.
- Unexpectedly, he admits to kidnapping
18 year old Marjorie Schneider.
He abducted Marjorie from the Lover's Lane.
Later shooting her in the head because he couldn't stand
to see anyone else having fun.
Robertson appears to be a strong candidate
for the Kalitzke Bogle murders.
- Notorious gangster James Whitey Bulger,
who's charged with rape in Great Falls five years earlier
is also a suspect.
- Sheriff Leeper has some strong leads.
He even looks at Patricia's family.
He requests a lie detector test because he is convinced
he will be interviewing for a confession.
- But the shocking response from the FBI forensic testing
is not one single suspect can be substantiated,
not even Floyd J. Robertson,
who is known as the Lover's Lane killer
in another place in time can be placed at this crime scene.
- [Narrator] A cash reward to find the killer
of Patricia and Lloyd is over the $1,000 mark,
a lot for the time.
But try as the police may, their leads dwindle.
- The case that had so many promising suspects
is now out of clues and outta leads.
- Although the officers are unwilling
and unable to forget these victims,
they have no other options.
- It's incredible just how many years will pass.
- To put that much effort into something
and you can't help but become emotional attached
at some point that it can be frustrating and disappointing
when a case does go cold.
(eerie music)
(intense music)
- [Narrator] There is an abundance of tips
in the investigation into the slaying of two teens in 1956,
but not one suspect could be substantiated
and the case falters.
Although law enforcement is driven to find an answer,
there is little trace of the killer.
- For the officer, this is a cold case.
He can't let go.
It's a cold case, but no one can stop looking at it.
- [Narrator] For decades,
the Cascade County Sheriff's Office
continued to examine this case.
Multiple detectives attempt to make progress over the years.
- But they can't gain any ground, time passes.
- [Narrator] 33 Years pass.
In 1989, law enforcement officers cut down
an 80 foot cottonwood tree near where Bogle is killed,
hoping to extract the bullet that killed him
and that has always been missing.
- They actually brought a clairvoyant type in
at the time,
had her actually hold Patty Kalitzke's petticoat.
It was kind of a blue longer coat,
which we obviously wouldn't have somebody holding evidence
in today's age,
but she actually described the answer to be in the tree.
- [Narrator] So officers look to the tree for the answer.
- With the bullet, authorities can determine
the caliber of the murder weapon.
There is a possibility it can be matched
with a weapon seized sometime over the last 33 years
and then everything opens up.
- This case is three decades old,
but the Cascade County Sheriff is still thinking of ways
to solve it.
- [Narrator] "Once we hit the 33 year mark on the tree,
we should see an entry If the bullet went into the tree,
a hole, a tunnel."
- Gamma Ray testing in the Cottonwood tree
surprisingly yields five bullets.
- They're sent to the FBI for testing,
but they come up with no matches from the bullets.
Another dead end.
- [Narrator] Time passes again.
In 2001, now 42 years since the rape and double murder,
another officer takes an action.
- DNA technology is slowly changing
and Detective Phil Madison sends the vaginal swab
the Montana State Crime Lab.
Lab technicians find a single sperm cell
and determined that it does not belong to Bogle.
- They were able to develop a DNA profile from that
which was ultimately entered into CODIS
and there were never any hits on that DNA.
- But they can't gain any ground, time passes.
(intense music)
- [Narrator] Forward 56 Years from the crime,
Detective Sergeant Jon Kadner
is assigned to the Kalitzke Bogle rape
and murder case in 2012.
- This is his very first cold case.
A cold case officer has to have certain qualities.
- You have to have somebody that is relentless
in trying to turn over every stone.
You have to look at every possibility,
you have to look at every document,
determine a possible motive to develop those leads.
One of the first things my lieutenant comes in at the time
and he says, "I want you to start reviewing this case
and we're gonna solve it someday."
So that started my process of looking through
these numerous boxes of old documents and reports
and I quickly realized the best course of action
was to digitize everything.
So that began a months long process
of scanning all those documents into a digital format.
- In fact, it took six months to digitize everything.
Though Kadner's given other cases,
he keeps looking to the Kalitzke Bogle case.
He believes DNA is the way in.
- [Narrator] "My first impression was that the only way
we're going to ever solve this is through the use of DNA."
- The mindset of the file was that over the years,
it has been gone through hundreds of times
and we still don't have a viable suspect.
- [Narrator] But this story is far from over.
It is 2019 when Kadner observes the progress
of another cold case.
- You see the use of genetic genealogy
in the Golden State Killer investigation,
which really got the ball rolling again.
- [Narrator] Justice Kadner had anticipated,
it's DNA that is able to unlock.
Joseph James DeAngelo Jr., the Golden State Killer,
known by many other names such as the Original Night Stalker
is one of California's most notorious serial killer rapists.
- He is a former police officer,
dangerous and widely known for stalking
and taunting both victims and law enforcement.
He's been able to get away with at least 50 rapes,
13 murders and 120 burglaries,
but his trail goes cold over three decades.
- [Narrator] But advances in technology
eventually turn the tide against him.
In a radical move, investigators upload
the Killer's DNA profile to a public genealogy site.
- And locate a fourth cousin of the killer.
From there, they create a family tree
and narrow down their search to find DeAngelo.
- [Narrator] DeAngelo is arrested and finally in June, 2020,
pleads guilty to 13 counts of first degree murder
and 13 counts of kidnapping
in a deal to avoid the death penalty.
He receives multiple consecutive life sentences
without the possibility of parole.
- Kadner watches the progress
of the Golden State Killer case
and sees the similarities with his Kalitzke Bogle case.
- [Narrator] And Kadner has DNA,
the microscopic slide of Patricia Kalitzke's vaginal swab
taken at her autopsy in 1956.
And back in 2001, detective Phil Madison did work
with the swab sample at the
Montana State Crime Lab.
- At the time it was all he could do,
but now technology seems to have caught up.
- The DNA was on a glass slide
and it was semen from Patty's body
that was recovered in 1956.
So that scientist that swabbed that slide in 2002
only swabbed half of it.
So the other half was still viable,
which ended up being a game changer for this case.
- [Narrator] Kadner seeks out the same
forensic service provider, which are instrumental in solving
the Golden State Killer case.
They undertake further testing on the the single sperm cell
taken from Patricia Kalitzke's body over 60 years earlier.
- The DNA profiles entered
into the public genealogy database
and they reversed engineer a family tree
to find the owner of the profile.
- Then investigators worked to determine
who could be a viable suspect.
- It was really fascinating how quickly
their genetic genealogists was able to start
building that family tree
because obviously they feed that sample into these databases
and then they come back with potential
still living relatives.
Based off those relatives,
they start researching open source information
on the internet and they start to build
that family tree backward and then ultimately,
determine who that potential suspect is.
So they wanna link up at least three individuals
that are still living to that one individual
and they call that a triangulation.
- [Narrator] And the process turns up three people
genetically compatible with the same
taken from Patricia Kalitzke,
one of them is Great Falls native, Kenneth Gould.
- And getting that information was probably
one of the most exciting experiences of my career.
But ultimately that's only an investigative lead.
That basically starts a whole new portion
of your investigation
because now you have to try to determine
if that individual is still alive.
- [Narrator] And Kenneth Gould is dead.
- He dies over 10 years earlier at the age of 79
and his body is cremated.
- [Narrator] "I wasn't sure how they were going to react
when I came to them saying,
hey, your dad's a suspect in this case.
But they were great to work with."
- They obviously did not believe
that their father was involved,
but they were cooperative.
They gave the DNA sample and that led to the match.
- [Narrator] DNA swabs from Kenneth Gould's children
linked their father to the murders.
- The Gould family is in shock.
A murder and rapist is not the father they knew.
The suspect is a surprise to everyone, including police.
They weren't looking for a person like Gould.
- They were focused on that monster.
They were looking for that serial killer.
It didn't appear that they were looking,
that it could be a neighbor from that area
or somebody that may have been infatuated with Patty.
They really focused on the criminals
who maybe had a history of murder or violent crime.
- [Narrator] Those who knew Gould can't believe
he's capable of murder.
- Now police go back in time to track Gould's history
and make sense of the man whose DNA
points to the killer next door.
(eerie music)
(sad music)
(gunshot bangs)
- [Narrator] The 1956 rape and double murder case goes cold.
But even though 60 years pass,
officers revisit the file time and time again.
A detective tasked with digitizing the case file
is inspired by the success of recent technology
and the capture of the Golden State Killer.
Using the same new technology,
the likeliest DNA a match is found
for a cold case from 1956.
- From 1956 to 2019,
over 60 years since the murder of Lloyd Bogle
and the rape and murder of Patricia Kalitzke,
police get the name of Kenneth Gould from DNA.
He's this suspect totally unknown to them.
- Detective Sergeant Kadner reaches out to his children.
They're surprised that their DNA backs up
their father's likely connection to the crime.
Because Gould is dead,
authorities can only refer to him
as the most likely suspect in this case.
- [Narrator] "This is as good as we're ever going to get
in a case like this."
- Detective Sergeant Kadner says that the Gould's family
does not dispute any of the facts.
One of the daughter states,
"Sometimes you just don't know everybody's secrets."
- [Narrator] Kenneth Gould is born August 23rd, 1927,
in Great Falls, Montana.
- There's a strange story that made the papers at the time.
In June, 1943, Gould 15 years old at the time
was reported missing from his grandmother's home in Buffalo.
He turned up a week later working
at a ranch in Arrow Creek about 60 miles away.
- [Narrator] In 1952, he's 24 when he marries
16 year old Lulu Bell Brown.
- The Gould home is in Tracy,
a little over a mile from where Patricia Kalitzke lived.
- [Narrator] And Gould's place of work is just a few blocks
from the Kalitzke home.
- He's known to ride horses through the area.
- It's likely Gould, Patricia,
and maybe even Lloyd had crossed paths before.
- [Narrator] And the night of January 2nd, 1956,
is the deadly convergence.
- That night, it's likely that after spending time
having coffee together,
Kalitzke and Bogle end up in his car in Lover's Lane.
- They were surprised by someone there,
an area known to be dark and private.
Officers at the time believe Patricia and Lloyd knew Gould
and weren't threatened by him.
But the scene turned violent.
(eerie music)
- Bogle is told to remove his belt.
His arms are restrained behind his back.
Lloyd Bogle is shot execution style in front of Patricia.
(gunshot bangs)
- [Narrator] She makes an attempt at escape
but is unsuccessful.
Her attacker drives her seven miles away.
She's beaten and raped and then executed
in the same manner as Bogle.
(gunshot bangs)
Her body is thrown down an icy embankment.
- Gould would've been 29 when the murders occurred.
- [Narrator] A little over a month after the murders,
Kenneth Gould sells his property in Tracy
and moves his family,
which includes a two month old daughter out of Great Falls.
- After moving around for several months,
they leave the state altogether
and settle in Alton, Missouri.
They never returned to Montana.
- Gould's daughter, an infant at the time of the murders,
dies in 1960 at age four after a short illness.
- [Narrator] And according to Kenneth Gould's
death certificate, he dies in Oregon County, Missouri,
on May 31st, 2007.
- Gould is never once interviewed
during the murder investigation.
He's completely under the police radar.
- My theory is that he was aware of who Patty Kalitzke was
and that he had an infatuation for her
and ultimately knew that area to be a Lover's Lane type area
and was there that night and committed the act.
(gunshot bangs)
(intense music)
- Of course, he gets out of town right away.
Who knows what might have been discovered at the time.
- And people at that time probably never thought,
hey, this could be my neighbor.
- [Narrator] Police research all of the places Gould lives
to see if there are any other unsolved homicides.
After the murder, he takes his family from Tracy
the Geraldine to Hamilton before he leaves the state
for once and for all and settles in Alton, Missouri.
- But they find nothing,
no crimes that show any relation to Kenneth Gould.
- Despite DNA pointing to Gould,
neighbors have a tough time reconciling this new information
with the man they know.
- Kenneth Gould is known as a man who didn't drink or swear,
didn't make trouble, was easygoing and soft spoken.
He was considered to be a good neighbor.
- But historically, we have friendly neighbors,
people who appear normal on the outside,
who later stunt and shock neighbors
with revelations that come out.
But this isn't unusual.
Neighbors are always shocked to learn
that somebody who lives next door to them,
somebody they've known for years
can be guilty of something so awful.
Fugitives will always try to keep a low profile
and draw no attention to themselves.
They live their lives like they have nothing to hide
when they have everything to hide,
which makes it very difficult to find them.
- He was living within a mile of Patty Kalitzke.
So you could start to put together that maybe this guy
did know Patty.
She had a paper route in that area so she would be around
in that neighborhood every morning.
And we also learned that a few blocks away
from Patty's house is where this man kept his horses.
And we also would learn that at that time,
people would ride their horses along the Sun River,
which he would've been very familiar with.
- The detectives who take the case to its conclusion
are not alive when the crime occurs.
They contact the remaining family members
to give them the answers they never expected to hear.
(intense music)
(somber music)
- [Narrator] A decades old cold case in Montana
finally gets a break.
- We have a rape and double murder case that went cold
but would not be buried.
- [Narrator] Over the scope of 60 years,
the double homicide cold case passes
from detective to detective.
- But there's a new crop of detectives coming up
with new ideas.
They aren't giving up on the goal of finding
Lloyd and Patricia's killer.
- [Narrator] Finally, technology finds this case
waiting and ready to be brought to its conclusion.
- However, there will never be a trial.
- We had to list him as a suspect
'cause obviously we could not say
that he was 100% responsible for this murder
because we weren't able to try him in the court.
But obviously we have the DNA match that that puts him
at the scene at that time.
- But is there really any closure to this case?
- You'll never really have that full closure
because ultimately he was never
had to face any consequences for his actions.
- It's a tragedy that had repercussions for so many,
like the Kalitzke's for example.
- Think it got to the point
where people did become suspicious of the family.
There's not a lot of details on what happened,
but it sounds like the family ultimately fell apart
because of the homicide.
So it did affect Patty Kalitzke's family.
- There's a real drive over generations to honor
these two young people who should have had
their whole lives ahead of them.

- When a homicide investigation goes cold,
the families of the victims may feel
that their loved ones have been forgotten.
- Most of Patricia and Lloyd's family members
are no longer living,
but those family members that Kadner can contact
are glad to have answers, as painful as they might be.
Kadner speaks to Lloyd's remaining family
who are still haunted by his murder all these years later.
- All the detectives who worked on this case over the years
shared the feeling of not being able to let go.
- And a lot of those investigators have passed on
without knowing what happened.
- [Narrator] A determination to see the case through
started in 1956 and would continue
from detective to detective.
"Quite frankly, that's our duty.
Our duty is to make sure that we solve these cases."
Sheriff Jesse Slaughter.
- The Kalitzke Bogle case is believed to be the oldest case
solved by this new technology.
- [Narrator] The double homicide might just still be
a cold case if not for the perfectly preserved swab
taken in 1956
and the advanced genetic DNA and genealogy techniques
that continue to evolve.
- But ultimately for these extremely old cases,
their success depends on how well the evidence is preserved.
- The importance of this technology
cannot be overemphasized.
DNA can solve stubborn mysteries
like the Golden State Killer case
and potentially save lives.
- That single DNA taken in 1956 is the key
and it would take decades for that evidence to be used.
- If not for one single sample of DNA
and the interest of some people in their family genealogy,
the murders of these two young people
would almost certainly never have been solved.
(sad music)
- Just the thought of how would they feel about this now,
knowing that their story is finally being told,
that's one reason that I've always wanted to continue
to tell this story is because I don't want them
to be forgotten.
They died in a tragic manner and I feel like it's my job
to tell their story.
