Bloodline Detectives - Season 2, Episode 3 - The Montana Murders - Full Episode | Forensic Files

[MUSIC PLAYING] - Good evening. I'm Nancy Grace. Tonight, an almost unbelievable test for "Bloodline
Detectives." 65 years after two high school sweethearts are brutally murdered, 21st century science
solves the case. NANCY GRACE (VOICEOVER): January 1956, rural Montana. Two bodies found in different locations,
but both had been murdered. PHIL MATTESON: These kids didn't have enemies. They didn't have people that didn't like them.
JON KADNER: People were on pins and needles. They weren't sure what to think and who
could have done such a thing. NANCY GRACE (VOICEOVER): As the investigation progresses,
detectives identify a number of suspects, even linking the case to a notorious Irish-American mobster.
SCOTT VAN DYKEN: Everybody knew who Whitey Bulger was. I mean, he was 10 Most Wanted forever.
He was on the run from the FBI for, like, 16 years. NANCY GRACE (VOICEOVER): But with the passage of time,
the case goes cold. Investigators fear their murders will never be solved. PHIL MATTESON: I was fairly resigned
that unless someone came forward with a tip, this was going to go unsolved. NANCY GRACE (VOICEOVER): Fast forward
65 years later, brand new DNA technology changes everything. Without genetic genealogy, this case
wouldn't have been solved. NANCY GRACE (VOICEOVER): This is the story of the unsolved murders of Duane Bogle and Patricia Kalitzke--
how they died and how the revolutionary science behind genetic DNA leads to a breakthrough for investigators.
This is "Bloodline Detectives." [MUSIC PLAYING] The countryside of Cascade County,
northwest of Great Falls, Montana. It's one of the most beautiful places in North America.
For a century, it's been a huge draw for campers and hikers who love the great outdoors, but it's
peace and tranquility is shattered in one afternoon January 1956. SCOTT VAN DYKEN: Three school kids
are just out at Wadsworth Park, they call it. It's a lover's lane. They go out there and they find this body next to a car.
PHIL MATTESON: He had been bound with his own belt, with his hands behind his back and he'd been
shot in the back of the head. JON KADNER: The vehicle had the emergency brake deployed.
The vehicle was in gear, the radio was on, and the headlights were on. PHIL MATTESON: It didn't appear that robbery was the motive.
There was a camera in the car that was expensive for its time and he still had money in his pocket.
NANCY GRACE (VOICEOVER): The boys immediately run for help. JON KADNER: Once they observed this dead body,
they ran to a nearby skating ring and law enforcement was summoned. NANCY GRACE (VOICEOVER): The sheriff's department,
quick on the scene, but in 1956, the use of forensics is crude compared to scientific tools investigators use today.
SCOTT VAN DYKEN: Today, it would be horrendous. Like, you'd lose your job if you did
what they did on a crime scene back then, but they didn't know. PHIL MATTESON: There was no crime scene security,
as we would have it now. There wasn't precautions as far as Tyvek suits because things like DNA hadn't been identified, yet.
JON KADNER: The evidence that they would have been looking for is a potential murder weapon.
Could they find a bullet that may have passed through his head and ended up on the ground?
They're looking for blood evidence, any damage to the vehicle. SCOTT VAN DYKEN: They fingerprinted the car
because they found a palm print on a car, but who knows where that got and where it came from.
They never did find a match for that. They never impounded cars. None of that stuff.
NANCY GRACE (VOICEOVER): The coroner is quickly on the scene. JON KADNER: The coroner would go to the scene and obviously,
try to find some identification on the body to try to determine who the victim was and basically,
process that scene to determine what exactly happened. NANCY GRACE (VOICEOVER): Police are
able to identify the deceased teen boy by his wallet found at the scene. TIM MCGONIGAL: The victim was Duane Bogle.
Duane was from Texas. He was an airman at Malmstrom Air Force Base. He was just, 18 years old so he was
fairly new into the Air Force. He was a good, upstanding young man that-- to my knowledge-- didn't have any problems
or no known real enemies or anything like that. NANCY GRACE (VOICEOVER): In one particular home in Great Falls
that evening, a family learns about the discovery of the body of Duane Bogle on the TV news.
Their own daughter is missing. Her name? Patricia Kalitzke. The Kalitzke's saw the news and got a hold of the sheriff's
office and let them know that Patty was with him the night before. SCOTT VAN DYKEN: They were boyfriend/girlfriend.
He was known to their family so as soon as he popped up on the TV, obviously, they knew something was up.
PHIL MATTESON: As soon as this was discovered, it became important to start looking for her
and obviously, she did not go home that night so then, the search expanded to looking for Patty.
(SINGING) La, la, la. [VOCALIZING] NANCY GRACE (VOICEOVER): Patty Kalitzke and Duane Bogle have been sweethearts just a short time.
JON KADNER: They had met on early December of 1955 and had, pretty much, been together
every night from that point. (SINGING) La, la, la. JESSE SLAUGHTER: He was probably,
somewhat of an honorable young man to be able to be in the home of his girlfriend's parents,
someplace where he's under probably, constant scrutiny, as any parent would be with a boyfriend in the house.
NANCY GRACE (VOICEOVER): Duane Bogle has become part of the Kalitzke family. TIM MCGONIGAL: They probably thought that Patricia, even
though she was young-- she was 16 at the time-- if she was going to get married to someone,
Duane would be a good guy for her. NANCY GRACE (VOICEOVER): Police began to piece together
events of the teen's evening. JON KADNER: That night, on January 2nd, they left the Kalitzke home, went to Pete's Drive-In
and got some food. And they left there about 9 o'clock at night and that was the last time anybody ever heard from them.
What Patty's mother suspected is that they potentially, had run off and got eloped and married.
NANCY GRACE: But this is clearly, not the case. What happened is violent, unexpected.
A brutal killer now on the loose and police know they need to find this killing machine and Patricia
Kalitzke, who's still missing. That's next, on "Bloodline Detectives." [MUSIC PLAYING]
1956 all anyone is talking about in the small city of Great Falls, Montana is the seemingly random
murder of an airman based at the local Malmstrom Air Force Base. Duane Bogle's body found the day before, close to Wadsworth
Park, northwest of the city. Now, 12 miles from that scene, another harrowing discovery.
PHIL MATTESON: A county road worker who's working on the road or checking the road up in Vineyard Road.
It's not far from Great Falls, but it's certainly, empty. There weren't many houses.
There was no businesses up there. It was a desolate road and there's some broken terrain there and the body had
been dumped over an embankment. NANCY GRACE (VOICEOVER): The sheriff soon has men on the scene.
JON KADNER: When law enforcement arrived, they found a female body that had been shot in the head.
The female was wearing a blue petticoat, a yellow skirt, and a yellow shirt. NANCY GRACE (VOICEOVER): Police identify the body
as that of Patty Kalitzke. It's what police and Patty's family have been sadly expecting.
Patty Kalitzke, reported missing the night before and police have already found Duane, her boyfriend's body.
PHIL MATTESON: It was just so extraordinary, so horrific [INAUDIBLE] the people that were around and a lot of people
knew Patty because she was a local girl, went to school here. It was shocking to the community and it continued to be.
NANCY GRACE (VOICEOVER): It's January and the nighttime temperature has taken its toll.
PHIL MATTESON: She had some frostbite to her toes and extremities and she was clothed
and their determination that she was not sexually assaulted. I'm not sure how they arrived at that at that time.
The autopsies then, were very simple compared to today's standards because the technology wasn't there.
Things like DNA weren't even thought about. They'd map the trajectory of the bullets as best they could.
They attempted to determine the caliber of the gun by measuring the size of the bullet holes,
but that wasn't truly specific, it was in general terms. NANCY GRACE (VOICEOVER): But contrary to views formed
at the crime scene, the autopsy on Patty Kalitzke determines she has been sex assaulted.
JESSE SLAUGHTER: The evidence is consistent with sexual assault. The medical examiner even indicated
that and the autopsy photos show a lot of injury to her legs, her ankles, her feet, her calves
consistent with a struggle. PHIL MATTESON: She had a skirt on so she would have had exposed legs if he made her walk any distance.
NANCY GRACE: Police launch a detailed investigation. PHIL MATTESON: They did a lot of interviews
with people who knew both of them and obviously, Duane had different friends and coworkers
than Patty's circle of friends and they interviewed people that knew them, trying to find any leads there.
If they could make a connection with one name to another name, they'd talk to them.
PHIL MATTESON: We're looking for information through the newspaper articles. People were encouraged if they had any information to contact
the sheriff's office. NANCY GRACE (VOICEOVER): Police immediately struggling with one thing--
a motive for the murders. PHIL MATTESON: A lot of theories and speculations, but there wasn't a really good one that anybody locked onto
and these kids didn't have enemies. They didn't have people that didn't like them.
They weren't doing things that would bring violence into their lives. They were good kids, behaving like kids do.
NANCY GRACE: It's 1956. Police now know, they are dealing with a dangerous and ruthless killer.
They must track him down as soon as possible. As we see next on "Bloodline Detectives," their list
of initial suspects includes one of the country's most notorious mobsters. [MUSIC PLAYING]
The year 1956. The city? Great Falls, Montana. Police continue their investigation
into the unexplained murders of a teen boy, Duane Bogle, and his girlfriend, 16-year-old Patrick Kalitzke.
The bodies of the two sweethearts found 12 miles apart and in the same 24 hour period,
but now, police are on the search for a killer and a motive, but by virtue of time and no real breakthrough,
the case goes cold. In the early part of the investigation, police identify a number of suspects.
There was some interest in other states and other similar crimes where people were
in similar circumstances were killed and they tried whatever was available. If there was a similar crime that another state had,
where a young couple were murdered and there was a suspect there, they investigated those to try and see if that person had
been in this area at that time. NANCY GRACE (VOICEOVER): Not long after the murders,
detectives focus their interest on one suspect-- Floyd Robertson. Floyd Robertson was a former airman that was
in Great Falls, stationed here. He got out and in 1958, he killed a young lady and, obviously, was being looked into as a potential suspect for
the murders of Duane and Patty. PHIL MATTESON: But he was determined to have not been here at the time that this crime occurred.
NANCY GRACE (VOICEOVER): Police soon identify another potential suspect-- Kenneth [INAUDIBLE]
JON KADNER: Kenneth [INAUDIBLE] was from Great Falls. He was a serial rapist, who ended up
in Sacramento, California, where he murdered and tortured a woman. PHIL MATTESON: He was a great suspect.
He had been in the area, from here. There was a lot of circumstantial evidence that made him look like a pretty good suspect,
but he was ultimately ruled out. JON KADNER: Arnold Blackwell was also, a former airman
that we looked into. From our documents, he had left the Great Falls area shortly
after the homicides and then, eventually, ended up in Oregon. SCOTT VAN DYKEN: As soon as the homicide occurred,
he put in for a transfer and moved up to Alaska. From Alaska, he was moved to Portland Air Base and right
outside the Portland Air Base, there was a similar homicide. He was later arrested for forcing
another airman to rape his wife at gunpoint, while he watched. The boyfriend/girlfriend, they were
killed at a lover's lane outside the Portland Air Base so his name came up. He was near this other lover's lane,
he had been in Great Falls, very violent crime and so, we started looking into him.
He had passed by the time that we were able to-- I was gone then, but I believe Captain Van Dyken was
in the process of getting ready to exhume his body to get some DNA to try and rule him in or out.
NANCY GRACE (VOICEOVER): One of the suspects is a notorious crime figure. JON KADNER: Whitey Bulger was a known killer, who
had potentially, murdered numerous people and during our research, we found that he was
in Great Falls in the 1950s. PHIL MATTESON: And he had been in our jail-- in Cascade County Jail--
at that time for a rape so here's a guy from out of town who had committed a rape in what is
normally, a very peaceful town. SCOTT VAN DYKEN: Everybody knew who Whitey Bulger was.
I mean, he was 10 Most Wanted forever. He was on the run from the government, from the FBI for, like, 16 years.
And he had been stationed at the air base so I thought, well, maybe he came back.
JON KADNER: With him being a known murderer, it was best to rule him out. We had his DNA compared to our DNA sample
and it did not match. In 1989, investigators wanted to X-ray the cottonwood tree where
Duane was shot in front of. Their theory was that there could be bullets inside that tree that could help solve the case.
They did X-ray that tree, found a section that had bullets inside of it, at which point, was cut out with a chainsaw,
and there was no murder weapon ever found. NANCY GRACE (VOICEOVER): Police work at least 35 leads over the years,
but every single one amounts to nothing. PHIL MATTESON: I was fairly resigned that unless someone came forward with a tip,
this was going to go unsolved. I did the math in my head many, times thinking, all right.
That person's 70 years old now. They're not out re-offending. If they haven't offended again since 1956,
they're not going to end up in the CODIS database and at that time, you had to have
a suspect to match to the DNA. You couldn't jump into these genealogy databases because they weren't there.
NANCY GRACE: It's virtually impossible to think, 65 long years after two murder cases go unsolved,
investigators get a scientific weapon to crack it all wide open. As we see next, the "Bloodline Detectives"
and a new DNA technology is about to change all that. [MUSIC PLAYING] By 2019, Montana police have all,
but given up hope of ever identifying the killer of two teens-- Duane Bogle and his sweetheart, Patricia Kalitzke.
The two were murdered in January 1956. Police never discovered who was the perp,
despite a long and intensive investigation stretching over many years. Now, Cascade County Police consider
using genetic genealogy. They apply for advanced testing to be done on a vaginal slide
taken at Patty's autopsy. Incredibly, from that slide, a DNA profile is developed.
JON KADNER: When I initially reviewed the case, I knew that DNA was likely going to be
the key to solving this case. However, we had not developed any suspects. In the early stages of the investigation,
I was in contact with Parabon Labs and I was researching DNA phenotyping, which they can basically, tell
you the nationality of your suspect, characteristics of your suspect-- that type of thing.
Then, genetic genealogy came around and that was where our focus went to and that started with the Golden State Killer being apprehended,
really put genetic genealogy on the map and really turned into a good tool for law enforcement
to use to identify these suspects. JESSE SLAUGHTER: Based on the success of that case,
Detective Kadner reached out to Bode Technology and started working with them to use genealogy to determine
who the possible suspect was. NANCY GRACE (VOICEOVER): One of the main suspects at this stage is a man named Edward Edwards
and police now try to see if his DNA matches the DNA profile they've obtained. JON KADNER: Edward Edwards is a known killer,
who was in Great Falls, Montana in March of 1956. He committed an armed robbery here in Great Falls and again,
in Billings, a few weeks later, at which time, he was apprehended. He was sentenced to the Montana State Prison
and he got released in 1959. PHIL MATTESON: He had gotten his stepson to go AWOL
and did murder him in an attempt to collect his life insurance money. He was an all-around bad guy.
He died in prison. He would have been a good suspect, except at the time that he came around as a suspect,
we already had identified DNA and he did not match. It was frustrating. We didn't have the ability to say yes or no
a lot of times when we look at a suspect, until we got the DNA. NANCY GRACE (VOICEOVER): At Bode Technology,
Teresa Vreeland is assigned to the case. TERESA VREELAND: I knew that it was a double homicide
and that the female in the homicide was also raped and so, the source of testing we were doing
was on a semen sample and so I knew that. I didn't know the victim's names at the time or any
of the different specifics about the case, itself, just how old it was. To make sure we were meeting the requirements,
I knew that it was a homicide and rape case and that, also, we had foreign male DNA to do testing on.
Bode's been around for over 25 years, helping with forensic DNA testing and we also have a databasing team
that tests the known samples of convicted or arrested offenders. The databases for genealogy are specific in the cases
that are allowed for searching and so they allow homicides, rapes, and one database
allows aggravated assault and they also allow unidentified remains so those are the bulk categories
of the cases I work. JON KADNER: Once your DNA sample is generated, that sample is
then uploaded into a voluntary database that people can use to basically, build their own family trees.
We load that sample into that database and then Bode Technology's genetic genealogist
is able to use open source information-- the internet-- to identify family members.
NANCY GRACE: There's something very important to note here. The samples taken from Patrick Kalitzke in 1956 have survived.
The Great Falls Police Department did an incredible job preserving them. In 1956, police could never have imagined
how valuable that slide would be this many years later. TERESA VREELAND: You need to store it in a dry, ideally dark
environment, with a very low humidity and so, normally, you can keep that room temperature--
temperature controlled. You don't want it to get too high of heat or too cold in the winters and usually,
it's packaged up so it's dark already. So you just want to protect it from moisture in sunlight,
ideally, is the best way to do it and they did that all these years with their evidence.
We had our analysts assigned to swab the smear so they got all materials off of that slide and into a tube
to do the DNA processing. We do an extraction, which opens up all of the cells to release
the DNA out, wash away the excess cellular debris, and are left with, ideally, clean and, in this case,
male DNA-- knowing it was from a semen sample-- and that was when I had a good idea
that we could be successful. I saw how much DNA we had, that we had enough to do this genetic genealogy testing
and so that was when I first started to get excited. I got to see, we have DNA from that many years ago.
PHIL MATTESON: The crime lab analyst called me some months later and told me that she had identified
a sperm cell on the slide, which it was a vaginal smear slide and they had identified a sperm cell
and my first question was, if I send you some blood from Duane Bogel, can you include or exclude him?
And we had some of his blood, either from a cigarette butt or from clothing, and they were able to say it was not him,
which told me that we had a sex crime, as well as a murder, and that we had the suspect's DNA.
TERESA VREELAND: When preserved right, the evidence will stay sufficient for new testing
and so, I just had the faith that Cascade County had preserved their evidence correctly.
They stored it over all these years. They just did everything right, that this profile
was still eligible to do this downstream testing 60-plus years later. PHIL MATTESON: This was the biggest break,
I think, in the case ever. NANCY GRACE (VOICEOVER): Detectives now begin to see where the profile
can be uploaded for comparison. PHIL MATTESON: The first thing we did was we ran it in the FBIs database CODIS
and we did not get a hit, which was terribly disappointing. I expected that someone who had done something
this heinous would have committed other offenses and that maybe we'd get him because everybody who's
got their DNA from violent crimes and sex crimes is in that database. And we did not get a hit.
I set it up with the FBI lab to run that every year so that all the new people that came into the database
would be checked against it, as well. And then, the next step was I looked at some
of the known suspects we had identified, but never ruled in or out and went through
and started determining who was in the CODIS database, who would we already excluded by virtue of having run that
and we eliminated some of those. NANCY GRACE (VOICEOVER): Teresa Vreeland and her colleagues
hone in on one family relationship, which turns out to match the sample. TERESA VREELAND: We were down to one name
in this particular case. There was a couple of siblings that could have also been candidates, but based on age and locations,
they were excluded. And so, with Sergeant Kadner, we issued a report with one person named and recommended
that it's an investigative lead for him to look in further and see if they can place this person as they would
need to in their investigation. It's hard to imagine that a sample taken 65 years ago
from Patty Kalitzke has survived and even harder to imagine, "Bloodline Detectives" can link it to her killer.
That's next, on "Bloodline Detectives." [MUSIC PLAYING] NANCY GRACE: Welcome back.
A 65-year-old DNA specimen added to 21st century forensic science by "Bloodline Detectives"
are now on the verge of solving a double murder. Their hard work pays off. Now, police can tie a name to the killer
of two high school sweethearts, a case that goes all the way back to 1956. The man's name?
Kenneth Gould. JESSE SLAUGHTER: Kenneth Gould basically trained horses in that area--
the area where Patty lived. SCOTT VAN DYKEN: He was just a working man. He broke horses for a living.
He was a ranch hand. He lived in the area, he kept his horses in the area so there's a good chance he knew who she was and had
seen her in the neighborhood. JESSE SLAUGHTER: Patty had a paper route there and so,
we're able to determine or speculate from the investigation that they had come in contact with each other probably, during that time.
NANCY GRACE (VOICEOVER): It appears Kenneth Gould has always been able to avoid contact with police.
JESSE SLAUGHTER: He didn't have any criminal history, whatsoever, so that leads me to believe probably, why he didn't
come up on their radar as a suspect during that point in time because this isn't a known criminal.
This isn't a person that is known. The fact that he committed a sex offense against Patty
is actually, very consistent with a lot of sex offenders. A lot of sex offenders go undetected
for multiple sexual assaults. One of the other things that I found really interesting
from my time working sex crimes is that Patty and Kenneth Gould's wife were the same age.
They were both 16 years old. So that was fascinating to me that he obviously had a type
and that's very consistent with people who commit sex crimes. NANCY GRACE (VOICEOVER): It also appears
Gould was anxious to get away from the area. JON KADNER: Soon after the murders,
Kenneth sold property in Tracy, Montana, which is about seven minutes outside of Great Falls.
He then moved the family to Geraldine, Montana and eventually, they end up in Hamilton, Montana
and they end up in Missouri for the remainder of their lives, never to return to Montana.
SCOTT VAN DYKEN: His story was in the media all the time and I think he ran from that.
And I think that's why he moved so much, is because he knew what he did and everybody was always talking about it
and there was always suspects popping up and I think he was running scared. I think he ran scared until he got down there
and he was probably, always looking over his shoulder. NANCY GRACE (VOICEOVER): But investigators
hunting the killer of Patty and Duane will be frustrated, once again. It appeared from the records that he was deceased
and likely cremated, as we couldn't find a final resting place for him. SCOTT VAN DYKEN: I think everybody still thought,
there's a chance that he's still alive and he was, when they first found him. I mean, he barely--
he passed away shortly before he got caught. TIM MCGONIGAL: We were able to get some comments from Gould's neighbor
when he lived in Missouri. They say that they can't believe that he was capable of doing
this because he was the nicest neighbor and his wife was also, the nicest person, but I suspect that she, like his family,
his children, had no idea that he could have committed this crime. NANCY GRACE (VOICEOVER): Ken Gould has been cremated.
The hope for a definitive identification narrows. For "Bloodline Detectives," there's
one more possibility to link Ken Gould to the murders. The potential to solve this case gets a lot harder
because without his body, we obviously cannot test his DNA so one of our options was to check
and see if he had a family. What we found is he had three children, one of which
was in Cascade County. The plan was to go meet with her, explain the situation, explain the case that we've been involved with,
and the potential of her father being a suspect. That was the discussion we had driving out to her residence.
How do we go about telling her that her father is the suspect in one of the most notorious murders in Cascade
County? JESSE SLAUGHTER: It's a very difficult thing to approach and you have to approach it with the need
to get the truth and the justice out of the situation, but also, you have to show some dignity because, just
because Kenneth is suspected of doing this, doesn't mean his family did anything wrong.
It's not their fault so you have to treat them with a lot of respect and dignity
so it's a very challenging conversation. We just, were honest with her and we told her the facts
and we said one way that we can either prove it was him or rule him out is by getting your DNA and testing it
and she was willing to give her DNA. TERESA VREELAND: The result we were anticipating--
that these children were in a parent-child predicted relationship based on DNA--
was, in fact, accurate and so I was able to deliver that report to Sergeant Kadner and let them know that they were,
in fact, the children of that semen sample left at the crime scene, which gives us confidence that Mr. Gould is the donor of that sample.
NANCY GRACE (VOICEOVER): The confirmation of Gould's guilt is obviously, something difficult for his children
to comprehend. PHIL MATTESON: How would that feel to find out that your loved one, family member, father, spouse
had done this and have no clue? SCOTT VAN DYKEN: There's a lot of people out there
that have done some horrible things and they never own up to it at the end. I mean, you'd think they'd say-- you think the goodness
in their heart-- if they had any goodness-- they'd own up to it, but they don't.
They never do that, for the most part, and it's, kind of, amazing. You'd think they'd step up and say, let
me tell you something I did. PHIL MATTESON: I knew that they had identified a suspect about a week before the press release.
Captain Van Dyken told me that there was going to be a press release and that it had been solved
and my first question was, was it someone that we looked at? And he told me no. I was so elated that they had pushed and followed through
and taken the new technology and done what they could and they had solved it. NANCY GRACE (VOICEOVER): The mystery surrounding
the murders is solved, but what happened all those years ago, January 1956? SCOTT VAN DYKEN: I think he recognized Patty
because I think he tied Duane's hands behind his back and she's probably, just sitting in the car
or just standing there and he's like, I'm not going to hurt, you just got to cooperate.
And I think he tied Duane's hands behind his back and then executed him and then he kidnapped her and took her.
JESSE SLAUGHTER: I think that the murders were probably calculated and I say that on the fact
that he obviously murders Duane first and then, sexually assaults Patty at some later point in time,
before he murders her. So he made sure that he eliminated the person that could protect her from the incident first.
He maybe had his eye on Patty from an interaction. Whether they actually had a conversation or not,
I don't think that matters. The fact that he probably was in the same area and saw her
and he's probably, a sexual predator and he had picked her out and then, he just waited for the time.
And I don't know if this time would have been a time of opportunity or if he would have planned it
so I can't speculate on that-- the mindset of the actual date-- but he had a plan.
He had a plan that he was going to take her at some point and he took advantage of this opportunity.
NANCY GRACE (VOICEOVER): It's impossible to know what really happened on that terrible day 1956,
but "Bloodline Detectives" know this. They solved the case and generations of Great
Falls Police never gave up. I guess, the case of the century, for us. I mean, it was a case that people worked
on at this agency for 65 years. I mean, it was just a way of life for some people.
They worked on it, worked on it, They get 15 minutes free, they'd go back and read some of the old reports
and some of the old reports were written in pencil on scraps of paper. And, I mean, it took months and months and months
to read all the reports on this thing. So, I guess, it was just a culture. The whole case was just, it was a way of life.
We work it. When you get a little time, you work it and when you're going to retire, I'm
going to assign it to somebody else, look into it, try something new, see if you think of something.
JESSE SLAUGHTER: How amazing it is that all of these detectives from 2001, from 1980s, from the '90s, from the '70s, '60s,
all the way back had historically kept working this case and trying to find the truth
and it just makes you feel proud of your profession. PHIL MATTESON: Through my whole career,
that was our only unsolved homicide. The victims and their families deserve justice
and if there's anything you can do to bring it to them, that's what you're supposed to do.
These people had their whole lives ahead of them. They were young, vibrant, healthy, decent, good people.
They didn't deserve any of this. They were just, young kids in love. NANCY GRACE: There are very important lessons
to be learned from the case. One, preserve evidence. Know you still may need it decades later.
Two, when new forensic weapons become available, use them. Three, never give up, even after 65 long years.
Generations of detectives in Great Falls, Montana did all of that and because of what they did,
a 65-year-old murder is now solved by "Bloodline Detectives." I'm Nancy Grace. Thanks for joining us tonight on "Bloodline Detectives."
