[MUSIC PLAYING] - Good evening. I'm Nancy Grace. Tonight, an almost unbelievable test for "Bloodline
00:00:17
Detectives." 65 years after two high school sweethearts are brutally murdered, 21st century science
00:00:26
solves the case. NANCY GRACE (VOICEOVER): January 1956, rural Montana. Two bodies found in different locations,
00:00:35
but both had been murdered. PHIL MATTESON: These kids didn't have enemies. They didn't have people that didn't like them.
00:00:43
JON KADNER: People were on pins and needles. They weren't sure what to think and who
00:00:47
could have done such a thing. NANCY GRACE (VOICEOVER): As the investigation progresses,
00:00:52
detectives identify a number of suspects, even linking the case to a notorious Irish-American mobster.
00:01:01
SCOTT VAN DYKEN: Everybody knew who Whitey Bulger was. I mean, he was 10 Most Wanted forever.
00:01:05
He was on the run from the FBI for, like, 16 years. NANCY GRACE (VOICEOVER): But with the passage of time,
00:01:11
the case goes cold. Investigators fear their murders will never be solved. PHIL MATTESON: I was fairly resigned
00:01:20
that unless someone came forward with a tip, this was going to go unsolved. NANCY GRACE (VOICEOVER): Fast forward
00:01:28
65 years later, brand new DNA technology changes everything. Without genetic genealogy, this case
00:01:38
wouldn't have been solved. NANCY GRACE (VOICEOVER): This is the story of the unsolved murders of Duane Bogle and Patricia Kalitzke--
00:01:47
how they died and how the revolutionary science behind genetic DNA leads to a breakthrough for investigators.
00:01:55
This is "Bloodline Detectives." [MUSIC PLAYING] The countryside of Cascade County,
00:02:26
northwest of Great Falls, Montana. It's one of the most beautiful places in North America.
00:02:32
For a century, it's been a huge draw for campers and hikers who love the great outdoors, but it's
00:02:43
peace and tranquility is shattered in one afternoon January 1956. SCOTT VAN DYKEN: Three school kids
00:02:51
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.
00:03:02
PHIL MATTESON: He had been bound with his own belt, with his hands behind his back and he'd been
00:03:06
shot in the back of the head. JON KADNER: The vehicle had the emergency brake deployed.
00:03:12
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.
00:03:20
There was a camera in the car that was expensive for its time and he still had money in his pocket.
00:03:31
NANCY GRACE (VOICEOVER): The boys immediately run for help. JON KADNER: Once they observed this dead body,
00:03:37
they ran to a nearby skating ring and law enforcement was summoned. NANCY GRACE (VOICEOVER): The sheriff's department,
00:03:45
quick on the scene, but in 1956, the use of forensics is crude compared to scientific tools investigators use today.
00:03:56
SCOTT VAN DYKEN: Today, it would be horrendous. Like, you'd lose your job if you did
00:04:00
what they did on a crime scene back then, but they didn't know. PHIL MATTESON: There was no crime scene security,
00:04:06
as we would have it now. There wasn't precautions as far as Tyvek suits because things like DNA hadn't been identified, yet.
00:04:16
JON KADNER: The evidence that they would have been looking for is a potential murder weapon.
00:04:21
Could they find a bullet that may have passed through his head and ended up on the ground?
00:04:26
They're looking for blood evidence, any damage to the vehicle. SCOTT VAN DYKEN: They fingerprinted the car
00:04:33
because they found a palm print on a car, but who knows where that got and where it came from.
00:04:38
They never did find a match for that. They never impounded cars. None of that stuff.
00:04:45
NANCY GRACE (VOICEOVER): The coroner is quickly on the scene. JON KADNER: The coroner would go to the scene and obviously,
00:04:52
try to find some identification on the body to try to determine who the victim was and basically,
00:05:01
process that scene to determine what exactly happened. NANCY GRACE (VOICEOVER): Police are
00:05:08
able to identify the deceased teen boy by his wallet found at the scene. TIM MCGONIGAL: The victim was Duane Bogle.
00:05:20
Duane was from Texas. He was an airman at Malmstrom Air Force Base. He was just, 18 years old so he was
00:05:27
fairly new into the Air Force. He was a good, upstanding young man that-- to my knowledge-- didn't have any problems
00:05:37
or no known real enemies or anything like that. NANCY GRACE (VOICEOVER): In one particular home in Great Falls
00:05:46
that evening, a family learns about the discovery of the body of Duane Bogle on the TV news.
00:05:54
Their own daughter is missing. Her name? Patricia Kalitzke. The Kalitzke's saw the news and got a hold of the sheriff's
00:06:07
office and let them know that Patty was with him the night before. SCOTT VAN DYKEN: They were boyfriend/girlfriend.
00:06:15
He was known to their family so as soon as he popped up on the TV, obviously, they knew something was up.
00:06:22
PHIL MATTESON: As soon as this was discovered, it became important to start looking for her
00:06:26
and obviously, she did not go home that night so then, the search expanded to looking for Patty.
00:06:32
(SINGING) La, la, la. [VOCALIZING] NANCY GRACE (VOICEOVER): Patty Kalitzke and Duane Bogle have been sweethearts just a short time.
00:06:42
JON KADNER: They had met on early December of 1955 and had, pretty much, been together
00:06:51
every night from that point. (SINGING) La, la, la. JESSE SLAUGHTER: He was probably,
00:06:57
somewhat of an honorable young man to be able to be in the home of his girlfriend's parents,
00:07:05
someplace where he's under probably, constant scrutiny, as any parent would be with a boyfriend in the house.
00:07:15
NANCY GRACE (VOICEOVER): Duane Bogle has become part of the Kalitzke family. TIM MCGONIGAL: They probably thought that Patricia, even
00:07:22
though she was young-- she was 16 at the time-- if she was going to get married to someone,
00:07:27
Duane would be a good guy for her. NANCY GRACE (VOICEOVER): Police began to piece together
00:07:34
events of the teen's evening. JON KADNER: That night, on January 2nd, they left the Kalitzke home, went to Pete's Drive-In
00:07:43
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.
00:07:54
What Patty's mother suspected is that they potentially, had run off and got eloped and married.
00:08:04
NANCY GRACE: But this is clearly, not the case. What happened is violent, unexpected.
00:08:11
A brutal killer now on the loose and police know they need to find this killing machine and Patricia
00:08:18
Kalitzke, who's still missing. That's next, on "Bloodline Detectives." [MUSIC PLAYING]
00:08:35
1956 all anyone is talking about in the small city of Great Falls, Montana is the seemingly random
00:08:43
murder of an airman based at the local Malmstrom Air Force Base. Duane Bogle's body found the day before, close to Wadsworth
00:08:52
Park, northwest of the city. Now, 12 miles from that scene, another harrowing discovery.
00:09:04
PHIL MATTESON: A county road worker who's working on the road or checking the road up in Vineyard Road.
00:09:11
It's not far from Great Falls, but it's certainly, empty. There weren't many houses.
00:09:17
There was no businesses up there. It was a desolate road and there's some broken terrain there and the body had
00:09:27
been dumped over an embankment. NANCY GRACE (VOICEOVER): The sheriff soon has men on the scene.
00:09:34
JON KADNER: When law enforcement arrived, they found a female body that had been shot in the head.
00:09:42
The female was wearing a blue petticoat, a yellow skirt, and a yellow shirt. NANCY GRACE (VOICEOVER): Police identify the body
00:09:53
as that of Patty Kalitzke. It's what police and Patty's family have been sadly expecting.
00:10:02
Patty Kalitzke, reported missing the night before and police have already found Duane, her boyfriend's body.
00:10:11
PHIL MATTESON: It was just so extraordinary, so horrific [INAUDIBLE] the people that were around and a lot of people
00:10:18
knew Patty because she was a local girl, went to school here. It was shocking to the community and it continued to be.
00:10:26
NANCY GRACE (VOICEOVER): It's January and the nighttime temperature has taken its toll.
00:10:33
PHIL MATTESON: She had some frostbite to her toes and extremities and she was clothed
00:10:41
and their determination that she was not sexually assaulted. I'm not sure how they arrived at that at that time.
00:10:50
The autopsies then, were very simple compared to today's standards because the technology wasn't there.
00:10:59
Things like DNA weren't even thought about. They'd map the trajectory of the bullets as best they could.
00:11:06
They attempted to determine the caliber of the gun by measuring the size of the bullet holes,
00:11:12
but that wasn't truly specific, it was in general terms. NANCY GRACE (VOICEOVER): But contrary to views formed
00:11:19
at the crime scene, the autopsy on Patty Kalitzke determines she has been sex assaulted.
00:11:27
JESSE SLAUGHTER: The evidence is consistent with sexual assault. The medical examiner even indicated
00:11:31
that and the autopsy photos show a lot of injury to her legs, her ankles, her feet, her calves
00:11:41
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.
00:11:53
NANCY GRACE: Police launch a detailed investigation. PHIL MATTESON: They did a lot of interviews
00:11:59
with people who knew both of them and obviously, Duane had different friends and coworkers
00:12:05
than Patty's circle of friends and they interviewed people that knew them, trying to find any leads there.
00:12:15
If they could make a connection with one name to another name, they'd talk to them.
00:12:21
PHIL MATTESON: We're looking for information through the newspaper articles. People were encouraged if they had any information to contact
00:12:27
the sheriff's office. NANCY GRACE (VOICEOVER): Police immediately struggling with one thing--
00:12:36
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
00:12:46
and these kids didn't have enemies. They didn't have people that didn't like them.
00:12:53
They weren't doing things that would bring violence into their lives. They were good kids, behaving like kids do.
00:13:05
NANCY GRACE: It's 1956. Police now know, they are dealing with a dangerous and ruthless killer.
00:13:12
They must track him down as soon as possible. As we see next on "Bloodline Detectives," their list
00:13:19
of initial suspects includes one of the country's most notorious mobsters. [MUSIC PLAYING]
00:13:38
The year 1956. The city? Great Falls, Montana. Police continue their investigation
00:13:45
into the unexplained murders of a teen boy, Duane Bogle, and his girlfriend, 16-year-old Patrick Kalitzke.
00:13:55
The bodies of the two sweethearts found 12 miles apart and in the same 24 hour period,
00:14:03
but now, police are on the search for a killer and a motive, but by virtue of time and no real breakthrough,
00:14:14
the case goes cold. In the early part of the investigation, police identify a number of suspects.
00:14:25
There was some interest in other states and other similar crimes where people were
00:14:31
in similar circumstances were killed and they tried whatever was available. If there was a similar crime that another state had,
00:14:39
where a young couple were murdered and there was a suspect there, they investigated those to try and see if that person had
00:14:46
been in this area at that time. NANCY GRACE (VOICEOVER): Not long after the murders,
00:14:50
detectives focus their interest on one suspect-- Floyd Robertson. Floyd Robertson was a former airman that was
00:15:00
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
00:15:11
the murders of Duane and Patty. PHIL MATTESON: But he was determined to have not been here at the time that this crime occurred.
00:15:21
NANCY GRACE (VOICEOVER): Police soon identify another potential suspect-- Kenneth [INAUDIBLE]
00:15:28
JON KADNER: Kenneth [INAUDIBLE] was from Great Falls. He was a serial rapist, who ended up
00:15:34
in Sacramento, California, where he murdered and tortured a woman. PHIL MATTESON: He was a great suspect.
00:15:41
He had been in the area, from here. There was a lot of circumstantial evidence that made him look like a pretty good suspect,
00:15:48
but he was ultimately ruled out. JON KADNER: Arnold Blackwell was also, a former airman
00:15:55
that we looked into. From our documents, he had left the Great Falls area shortly
00:16:02
after the homicides and then, eventually, ended up in Oregon. SCOTT VAN DYKEN: As soon as the homicide occurred,
00:16:13
he put in for a transfer and moved up to Alaska. From Alaska, he was moved to Portland Air Base and right
00:16:23
outside the Portland Air Base, there was a similar homicide. He was later arrested for forcing
00:16:29
another airman to rape his wife at gunpoint, while he watched. The boyfriend/girlfriend, they were
00:16:35
killed at a lover's lane outside the Portland Air Base so his name came up. He was near this other lover's lane,
00:16:41
he had been in Great Falls, very violent crime and so, we started looking into him.
00:16:49
He had passed by the time that we were able to-- I was gone then, but I believe Captain Van Dyken was
00:16:58
in the process of getting ready to exhume his body to get some DNA to try and rule him in or out.
00:17:07
NANCY GRACE (VOICEOVER): One of the suspects is a notorious crime figure. JON KADNER: Whitey Bulger was a known killer, who
00:17:18
had potentially, murdered numerous people and during our research, we found that he was
00:17:24
in Great Falls in the 1950s. PHIL MATTESON: And he had been in our jail-- in Cascade County Jail--
00:17:33
at that time for a rape so here's a guy from out of town who had committed a rape in what is
00:17:40
normally, a very peaceful town. SCOTT VAN DYKEN: Everybody knew who Whitey Bulger was.
00:17:44
I mean, he was 10 Most Wanted forever. He was on the run from the government, from the FBI for, like, 16 years.
00:17:54
And he had been stationed at the air base so I thought, well, maybe he came back.
00:18:02
JON KADNER: With him being a known murderer, it was best to rule him out. We had his DNA compared to our DNA sample
00:18:14
and it did not match. In 1989, investigators wanted to X-ray the cottonwood tree where
00:18:27
Duane was shot in front of. Their theory was that there could be bullets inside that tree that could help solve the case.
00:18:37
They did X-ray that tree, found a section that had bullets inside of it, at which point, was cut out with a chainsaw,
00:18:46
and there was no murder weapon ever found. NANCY GRACE (VOICEOVER): Police work at least 35 leads over the years,
00:18:56
but every single one amounts to nothing. PHIL MATTESON: I was fairly resigned that unless someone came forward with a tip,
00:19:07
this was going to go unsolved. I did the math in my head many, times thinking, all right.
00:19:13
That person's 70 years old now. They're not out re-offending. If they haven't offended again since 1956,
00:19:22
they're not going to end up in the CODIS database and at that time, you had to have
00:19:26
a suspect to match to the DNA. You couldn't jump into these genealogy databases because they weren't there.
00:19:36
NANCY GRACE: It's virtually impossible to think, 65 long years after two murder cases go unsolved,
00:19:44
investigators get a scientific weapon to crack it all wide open. As we see next, the "Bloodline Detectives"
00:19:53
and a new DNA technology is about to change all that. [MUSIC PLAYING] By 2019, Montana police have all,
00:20:13
but given up hope of ever identifying the killer of two teens-- Duane Bogle and his sweetheart, Patricia Kalitzke.
00:20:21
The two were murdered in January 1956. Police never discovered who was the perp,
00:20:28
despite a long and intensive investigation stretching over many years. Now, Cascade County Police consider
00:20:40
using genetic genealogy. They apply for advanced testing to be done on a vaginal slide
00:20:47
taken at Patty's autopsy. Incredibly, from that slide, a DNA profile is developed.
00:21:01
JON KADNER: When I initially reviewed the case, I knew that DNA was likely going to be
00:21:05
the key to solving this case. However, we had not developed any suspects. In the early stages of the investigation,
00:21:14
I was in contact with Parabon Labs and I was researching DNA phenotyping, which they can basically, tell
00:21:23
you the nationality of your suspect, characteristics of your suspect-- that type of thing.
00:21:29
Then, genetic genealogy came around and that was where our focus went to and that started with the Golden State Killer being apprehended,
00:21:41
really put genetic genealogy on the map and really turned into a good tool for law enforcement
00:21:47
to use to identify these suspects. JESSE SLAUGHTER: Based on the success of that case,
00:21:54
Detective Kadner reached out to Bode Technology and started working with them to use genealogy to determine
00:22:00
who the possible suspect was. NANCY GRACE (VOICEOVER): One of the main suspects at this stage is a man named Edward Edwards
00:22:07
and police now try to see if his DNA matches the DNA profile they've obtained. JON KADNER: Edward Edwards is a known killer,
00:22:19
who was in Great Falls, Montana in March of 1956. He committed an armed robbery here in Great Falls and again,
00:22:28
in Billings, a few weeks later, at which time, he was apprehended. He was sentenced to the Montana State Prison
00:22:36
and he got released in 1959. PHIL MATTESON: He had gotten his stepson to go AWOL
00:22:47
and did murder him in an attempt to collect his life insurance money. He was an all-around bad guy.
00:22:54
He died in prison. He would have been a good suspect, except at the time that he came around as a suspect,
00:23:00
we already had identified DNA and he did not match. It was frustrating. We didn't have the ability to say yes or no
00:23:11
a lot of times when we look at a suspect, until we got the DNA. NANCY GRACE (VOICEOVER): At Bode Technology,
00:23:18
Teresa Vreeland is assigned to the case. TERESA VREELAND: I knew that it was a double homicide
00:23:24
and that the female in the homicide was also raped and so, the source of testing we were doing
00:23:30
was on a semen sample and so I knew that. I didn't know the victim's names at the time or any
00:23:37
of the different specifics about the case, itself, just how old it was. To make sure we were meeting the requirements,
00:23:43
I knew that it was a homicide and rape case and that, also, we had foreign male DNA to do testing on.
00:23:51
Bode's been around for over 25 years, helping with forensic DNA testing and we also have a databasing team
00:23:58
that tests the known samples of convicted or arrested offenders. The databases for genealogy are specific in the cases
00:24:07
that are allowed for searching and so they allow homicides, rapes, and one database
00:24:13
allows aggravated assault and they also allow unidentified remains so those are the bulk categories
00:24:19
of the cases I work. JON KADNER: Once your DNA sample is generated, that sample is
00:24:27
then uploaded into a voluntary database that people can use to basically, build their own family trees.
00:24:37
We load that sample into that database and then Bode Technology's genetic genealogist
00:24:43
is able to use open source information-- the internet-- to identify family members.
00:24:53
NANCY GRACE: There's something very important to note here. The samples taken from Patrick Kalitzke in 1956 have survived.
00:25:01
The Great Falls Police Department did an incredible job preserving them. In 1956, police could never have imagined
00:25:11
how valuable that slide would be this many years later. TERESA VREELAND: You need to store it in a dry, ideally dark
00:25:22
environment, with a very low humidity and so, normally, you can keep that room temperature--
00:25:28
temperature controlled. You don't want it to get too high of heat or too cold in the winters and usually,
00:25:35
it's packaged up so it's dark already. So you just want to protect it from moisture in sunlight,
00:25:40
ideally, is the best way to do it and they did that all these years with their evidence.
00:25:48
We had our analysts assigned to swab the smear so they got all materials off of that slide and into a tube
00:25:55
to do the DNA processing. We do an extraction, which opens up all of the cells to release
00:26:01
the DNA out, wash away the excess cellular debris, and are left with, ideally, clean and, in this case,
00:26:09
male DNA-- knowing it was from a semen sample-- and that was when I had a good idea
00:26:14
that we could be successful. I saw how much DNA we had, that we had enough to do this genetic genealogy testing
00:26:22
and so that was when I first started to get excited. I got to see, we have DNA from that many years ago.
00:26:31
PHIL MATTESON: The crime lab analyst called me some months later and told me that she had identified
00:26:38
a sperm cell on the slide, which it was a vaginal smear slide and they had identified a sperm cell
00:26:47
and my first question was, if I send you some blood from Duane Bogel, can you include or exclude him?
00:26:55
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,
00:27:02
which told me that we had a sex crime, as well as a murder, and that we had the suspect's DNA.
00:27:11
TERESA VREELAND: When preserved right, the evidence will stay sufficient for new testing
00:27:16
and so, I just had the faith that Cascade County had preserved their evidence correctly.
00:27:22
They stored it over all these years. They just did everything right, that this profile
00:27:27
was still eligible to do this downstream testing 60-plus years later. PHIL MATTESON: This was the biggest break,
00:27:36
I think, in the case ever. NANCY GRACE (VOICEOVER): Detectives now begin to see where the profile
00:27:42
can be uploaded for comparison. PHIL MATTESON: The first thing we did was we ran it in the FBIs database CODIS
00:27:50
and we did not get a hit, which was terribly disappointing. I expected that someone who had done something
00:27:55
this heinous would have committed other offenses and that maybe we'd get him because everybody who's
00:28:03
got their DNA from violent crimes and sex crimes is in that database. And we did not get a hit.
00:28:10
I set it up with the FBI lab to run that every year so that all the new people that came into the database
00:28:18
would be checked against it, as well. And then, the next step was I looked at some
00:28:24
of the known suspects we had identified, but never ruled in or out and went through
00:28:30
and started determining who was in the CODIS database, who would we already excluded by virtue of having run that
00:28:37
and we eliminated some of those. NANCY GRACE (VOICEOVER): Teresa Vreeland and her colleagues
00:28:42
hone in on one family relationship, which turns out to match the sample. TERESA VREELAND: We were down to one name
00:28:51
in this particular case. There was a couple of siblings that could have also been candidates, but based on age and locations,
00:28:58
they were excluded. And so, with Sergeant Kadner, we issued a report with one person named and recommended
00:29:05
that it's an investigative lead for him to look in further and see if they can place this person as they would
00:29:11
need to in their investigation. It's hard to imagine that a sample taken 65 years ago
00:29:17
from Patty Kalitzke has survived and even harder to imagine, "Bloodline Detectives" can link it to her killer.
00:29:27
That's next, on "Bloodline Detectives." [MUSIC PLAYING] NANCY GRACE: Welcome back.
00:29:40
A 65-year-old DNA specimen added to 21st century forensic science by "Bloodline Detectives"
00:29:48
are now on the verge of solving a double murder. Their hard work pays off. Now, police can tie a name to the killer
00:29:59
of two high school sweethearts, a case that goes all the way back to 1956. The man's name?
00:30:09
Kenneth Gould. JESSE SLAUGHTER: Kenneth Gould basically trained horses in that area--
00:30:15
the area where Patty lived. SCOTT VAN DYKEN: He was just a working man. He broke horses for a living.
00:30:20
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
00:30:28
seen her in the neighborhood. JESSE SLAUGHTER: Patty had a paper route there and so,
00:30:36
we're able to determine or speculate from the investigation that they had come in contact with each other probably, during that time.
00:30:44
NANCY GRACE (VOICEOVER): It appears Kenneth Gould has always been able to avoid contact with police.
00:30:52
JESSE SLAUGHTER: He didn't have any criminal history, whatsoever, so that leads me to believe probably, why he didn't
00:30:58
come up on their radar as a suspect during that point in time because this isn't a known criminal.
00:31:03
This isn't a person that is known. The fact that he committed a sex offense against Patty
00:31:08
is actually, very consistent with a lot of sex offenders. A lot of sex offenders go undetected
00:31:15
for multiple sexual assaults. One of the other things that I found really interesting
00:31:21
from my time working sex crimes is that Patty and Kenneth Gould's wife were the same age.
00:31:27
They were both 16 years old. So that was fascinating to me that he obviously had a type
00:31:35
and that's very consistent with people who commit sex crimes. NANCY GRACE (VOICEOVER): It also appears
00:31:40
Gould was anxious to get away from the area. JON KADNER: Soon after the murders,
00:31:46
Kenneth sold property in Tracy, Montana, which is about seven minutes outside of Great Falls.
00:31:54
He then moved the family to Geraldine, Montana and eventually, they end up in Hamilton, Montana
00:32:02
and they end up in Missouri for the remainder of their lives, never to return to Montana.
00:32:14
SCOTT VAN DYKEN: His story was in the media all the time and I think he ran from that.
00:32:18
And I think that's why he moved so much, is because he knew what he did and everybody was always talking about it
00:32:26
and there was always suspects popping up and I think he was running scared. I think he ran scared until he got down there
00:32:31
and he was probably, always looking over his shoulder. NANCY GRACE (VOICEOVER): But investigators
00:32:36
hunting the killer of Patty and Duane will be frustrated, once again. It appeared from the records that he was deceased
00:32:45
and likely cremated, as we couldn't find a final resting place for him. SCOTT VAN DYKEN: I think everybody still thought,
00:32:52
there's a chance that he's still alive and he was, when they first found him. I mean, he barely--
00:32:59
he passed away shortly before he got caught. TIM MCGONIGAL: We were able to get some comments from Gould's neighbor
00:33:06
when he lived in Missouri. They say that they can't believe that he was capable of doing
00:33:13
this because he was the nicest neighbor and his wife was also, the nicest person, but I suspect that she, like his family,
00:33:26
his children, had no idea that he could have committed this crime. NANCY GRACE (VOICEOVER): Ken Gould has been cremated.
00:33:36
The hope for a definitive identification narrows. For "Bloodline Detectives," there's
00:33:43
one more possibility to link Ken Gould to the murders. The potential to solve this case gets a lot harder
00:33:54
because without his body, we obviously cannot test his DNA so one of our options was to check
00:34:01
and see if he had a family. What we found is he had three children, one of which
00:34:08
was in Cascade County. The plan was to go meet with her, explain the situation, explain the case that we've been involved with,
00:34:22
and the potential of her father being a suspect. That was the discussion we had driving out to her residence.
00:34:31
How do we go about telling her that her father is the suspect in one of the most notorious murders in Cascade
00:34:39
County? JESSE SLAUGHTER: It's a very difficult thing to approach and you have to approach it with the need
00:34:47
to get the truth and the justice out of the situation, but also, you have to show some dignity because, just
00:34:55
because Kenneth is suspected of doing this, doesn't mean his family did anything wrong.
00:35:01
It's not their fault so you have to treat them with a lot of respect and dignity
00:35:05
so it's a very challenging conversation. We just, were honest with her and we told her the facts
00:35:12
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
00:35:20
and she was willing to give her DNA. TERESA VREELAND: The result we were anticipating--
00:35:29
that these children were in a parent-child predicted relationship based on DNA--
00:35:34
was, in fact, accurate and so I was able to deliver that report to Sergeant Kadner and let them know that they were,
00:35:42
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.
00:35:52
NANCY GRACE (VOICEOVER): The confirmation of Gould's guilt is obviously, something difficult for his children
00:35:58
to comprehend. PHIL MATTESON: How would that feel to find out that your loved one, family member, father, spouse
00:36:07
had done this and have no clue? SCOTT VAN DYKEN: There's a lot of people out there
00:36:14
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
00:36:20
in their heart-- if they had any goodness-- they'd own up to it, but they don't.
00:36:24
They never do that, for the most part, and it's, kind of, amazing. You'd think they'd step up and say, let
00:36:29
me tell you something I did. PHIL MATTESON: I knew that they had identified a suspect about a week before the press release.
00:36:38
Captain Van Dyken told me that there was going to be a press release and that it had been solved
00:36:44
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
00:36:55
and taken the new technology and done what they could and they had solved it. NANCY GRACE (VOICEOVER): The mystery surrounding
00:37:08
the murders is solved, but what happened all those years ago, January 1956? SCOTT VAN DYKEN: I think he recognized Patty
00:37:18
because I think he tied Duane's hands behind his back and she's probably, just sitting in the car
00:37:23
or just standing there and he's like, I'm not going to hurt, you just got to cooperate.
00:37:28
And I think he tied Duane's hands behind his back and then executed him and then he kidnapped her and took her.
00:37:35
JESSE SLAUGHTER: I think that the murders were probably calculated and I say that on the fact
00:37:39
that he obviously murders Duane first and then, sexually assaults Patty at some later point in time,
00:37:46
before he murders her. So he made sure that he eliminated the person that could protect her from the incident first.
00:37:55
He maybe had his eye on Patty from an interaction. Whether they actually had a conversation or not,
00:38:03
I don't think that matters. The fact that he probably was in the same area and saw her
00:38:08
and he's probably, a sexual predator and he had picked her out and then, he just waited for the time.
00:38:16
And I don't know if this time would have been a time of opportunity or if he would have planned it
00:38:23
so I can't speculate on that-- the mindset of the actual date-- but he had a plan.
00:38:29
He had a plan that he was going to take her at some point and he took advantage of this opportunity.
00:38:40
NANCY GRACE (VOICEOVER): It's impossible to know what really happened on that terrible day 1956,
00:38:46
but "Bloodline Detectives" know this. They solved the case and generations of Great
00:38:52
Falls Police never gave up. I guess, the case of the century, for us. I mean, it was a case that people worked
00:39:02
on at this agency for 65 years. I mean, it was just a way of life for some people.
00:39:07
They worked on it, worked on it, They get 15 minutes free, they'd go back and read some of the old reports
00:39:13
and some of the old reports were written in pencil on scraps of paper. And, I mean, it took months and months and months
00:39:19
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.
00:39:26
We work it. When you get a little time, you work it and when you're going to retire, I'm
00:39:31
going to assign it to somebody else, look into it, try something new, see if you think of something.
00:39:38
JESSE SLAUGHTER: How amazing it is that all of these detectives from 2001, from 1980s, from the '90s, from the '70s, '60s,
00:39:46
all the way back had historically kept working this case and trying to find the truth
00:39:51
and it just makes you feel proud of your profession. PHIL MATTESON: Through my whole career,
00:39:59
that was our only unsolved homicide. The victims and their families deserve justice
00:40:03
and if there's anything you can do to bring it to them, that's what you're supposed to do.
00:40:09
These people had their whole lives ahead of them. They were young, vibrant, healthy, decent, good people.
00:40:17
They didn't deserve any of this. They were just, young kids in love. NANCY GRACE: There are very important lessons
00:40:28
to be learned from the case. One, preserve evidence. Know you still may need it decades later.
00:40:37
Two, when new forensic weapons become available, use them. Three, never give up, even after 65 long years.
00:40:49
Generations of detectives in Great Falls, Montana did all of that and because of what they did,
00:40:56
a 65-year-old murder is now solved by "Bloodline Detectives." I'm Nancy Grace. Thanks for joining us tonight on "Bloodline Detectives."
