00:00:00.020 --> 00:00:08.839
The year is 1986, the place, Perth, in Western Australia, where the sun beat down on quiet suburban streets.
00:00:09.119 --> 00:00:16.660
It was the kind of place where kids rode bikes until dark and families gathered for barbecues. It was a city that felt safe.
00:00:16.960 --> 00:00:28.260
Far from the horrors of the world splashed across international headlines, but behind the closed doors of an ordinary house on Morehouse Street, something terrifying was happening.
00:00:28.260 --> 00:00:32.859
Over the course of just five weeks, four young women would vanish.
00:00:33.060 --> 00:00:39.759
Their families would be left begging for answers. Their faces would appear on posters and nightly news reports.
00:00:40.000 --> 00:00:44.200
And the community would feel a chill it had never known before.
00:00:44.520 --> 00:00:48.960
The world would later come to know these crimes as the Morehouse murders.
00:00:49.259 --> 00:00:55.679
And at the center of it all was not just one killer, but a pair, David and Catherine Birnie.
00:00:56.179 --> 00:01:07.040
Welcome to GBRLIFE Transmissions. I'm your host, Kaitlyn, and you're listening to GBRLIFE of Crimes, where we explore not just what happened in crimes committed by women, but why they happened and the psychology behind them.
00:01:07.459 --> 00:01:19.140
Today, we're diving into the story of Catherine Birnie, a woman whose life choices and toxic partnership with David Birnie led to one of the most disturbing killing sprees in Australian history.
00:01:20.109 --> 00:01:27.450
Catherine Harrison was born in 1951 in Perth. From the start, her life was marked by instability.
00:01:27.829 --> 00:01:35.069
Her mother died when Catherine was just two years old, and her father, unable to cope, placed her into the care of relatives.
00:01:35.349 --> 00:01:44.569
That sense of abandonment stayed with her. In the depths of her inner world, while her outer world began what she felt was a normal life.
00:01:44.569 --> 00:01:56.310
And she remained that way until Catherine was a teenager when she would meet David Birnie, a boy who seemed confident, rebellious, and dangerous. She was just 14.
00:01:56.969 --> 00:02:01.430
He was older, manipulative, and already showing troubling behaviors.
00:02:01.870 --> 00:02:14.469
For Catherine, David wasn't just a boyfriend. He was an escape from loneliness, from feeling unwanted, and having no way to express that. David made Catherine feel seen.
00:02:14.610 --> 00:02:20.129
And as you might have guessed, that bond, as toxic as it was, would define her life.
00:02:20.310 --> 00:02:22.610
This was first love territory for Catherine.
00:02:22.969 --> 00:02:28.909
So David was her world. Wondering if her family liked David, they knew he was not a good influence.
00:02:29.129 --> 00:02:36.849
So they immediately disapproved. And surprisingly, when Catherine's family disapproved, the couple were indeed separated.
00:02:37.129 --> 00:02:43.729
Which means she did not try to become that rebellious teenager and stay with him anyway. No, she followed the rules.
00:02:43.949 --> 00:02:50.289
She stayed that way into adulthood, even going on to marry another man, Donald McLaughlin.
00:02:50.469 --> 00:02:55.590
They went on to have six children and live a relatively conventional life.
00:02:55.729 --> 00:03:03.930
Although friends did report that it wasn't as settled as it appeared, with potential abuse going on, but this wasn't confirmed.
00:03:04.150 --> 00:03:16.629
And Catherine did not get to keep her kids. They went with their father because he had the money. And once she saw the situation, she decided to stop trying, possibly due to her abandonment issues.
00:03:16.830 --> 00:03:21.949
And during this time, Catherine found herself drawn back to the guy she once knew, David.
00:03:22.580 --> 00:03:30.180
And she was the one who went looking for him. Luckily for her, when she went looking for David, he was also divorced.
00:03:30.379 --> 00:03:39.240
And they went full force into a relationship, moving into David's home at 3 Morehouse Street in Perth almost immediately.
00:03:39.580 --> 00:03:49.979
And remember at this point, she was deciding not to fight for her kids, which means her goal in life was only David and nothing and no one else mattered.
00:03:49.979 --> 00:03:55.319
And it was at this point that David had told Catherine about his fantasies of S.A.
00:03:55.659 --> 00:03:59.840
And harming others. And he told Catherine about them openly, without fear.
00:04:00.340 --> 00:04:04.280
Instead of running, Catherine agreed to join him. But why?
00:04:04.520 --> 00:04:08.800
That's the haunting question because first love or not, this was not a small cork.
00:04:08.919 --> 00:04:15.520
It was a clear admission to psychological disturbance, which is why we have to ask again, why?
00:04:15.800 --> 00:04:24.620
Was it fear of losing him? Was it codependence? Or was it something darker inside Catherine herself that was unlocked by his influence?
00:04:24.920 --> 00:04:26.560
Together they made a pact.
00:04:27.180 --> 00:04:30.420
Catherine reportedly told David, I'll do anything for you. Anything.
00:04:30.720 --> 00:04:42.959
And she proved it. In October of 1986, the couple lured their first victim, 22-year-old Mary Nielsen, to their home under the pretense of selling cheap car tires.
00:04:43.319 --> 00:04:51.339
Once inside, Mary was overpowered, harmed, and Unalived . Over the next month, three more women would suffer the same fate.
00:04:51.579 --> 00:04:55.860
The victims' ages all ranged from 15 to 31.
00:04:56.199 --> 00:05:06.279
Each was lured into the house, restrained, harmed, and then often strangled or intoxicated before being placed into shallow graves outside Perth.
00:05:06.480 --> 00:05:07.899
Catherine's role was chilling.
00:05:08.199 --> 00:05:19.860
She helped lure the victims. She was the one who opened the door, who made the girls feel safe enough to step

inside. In many cases, she tied the ligatures or handed David the tools.
00:05:20.180 --> 00:05:31.819
She wasn't just a bystander, she was an active participant, and the Bernies might have continued killing, but their final intended victim, 17-year-old Kate, managed to escape.
00:05:32.120 --> 00:05:40.100
She convinced Catherine to let her call home, and when given a brief chance, she fled the house barefoot, alerting neighbors and then police.
00:05:40.670 --> 00:05:47.930
Her testimony blew the case open. Police raided the Birnie home, uncovering evidence of the attacks and hearing chilling confessions.
00:05:48.209 --> 00:05:55.250
Both David and Catherine admitted to their crimes. And this is where we pause and ask, why? One more time.
00:05:55.769 --> 00:06:01.350
Catherine Bernie is not the stereotype of female killer acting in self-defense or out of desperation.
00:06:01.589 --> 00:06:10.709
She joined willingly. And psychologists point to her lifelong attachment to David, her need for control through him, and her abandonment trauma.
00:06:11.069 --> 00:06:17.490
In Catherine's world, pleasing David meant survival, but it also gave her a twisted sense of belonging.
00:06:17.709 --> 00:06:29.889
And some experts believe she had what's called secondary psychopath, someone who may not have initiated the crimes, but who found identity and purpose in carrying them out alongside her partner.
00:06:30.209 --> 00:06:33.069
And in interviews, she showed little remorse.
00:06:33.430 --> 00:06:37.170
David Birnie took his own life in prison in 2005.
00:06:37.870 --> 00:06:42.470
Catherine remains behind bars to this day, serving a life sentence with no chance of parole.
00:06:42.750 --> 00:06:49.170
She was one of the very few women in Australia who's been officially designated as never to be released.
00:06:49.529 --> 00:06:53.970
For the families of the victims, her imprisonment is only a fragment of justice.
00:06:54.910 --> 00:06:58.089
Their daughters never came home. Their futures were stolen.
00:06:58.529 --> 00:07:03.550
Their names forever remembered Mary Nielsen, Savannah Candy.
00:07:04.209 --> 00:07:10.009
Nolene Patterson, and Denise Brown. became a grim reminder etched into Perth's history.
00:07:10.189 --> 00:07:14.689
And then there was Kate, Kate Moir, the 17-year-old girl who survived.
00:07:15.110 --> 00:07:19.509
The girl who ran barefoot from the Morehouse Street and exposed the Bernies to the world.
00:07:19.829 --> 00:07:25.230
Kate later spoke about the trauma of being the one who lived, carrying survivor's guilt for decades.
00:07:25.449 --> 00:07:33.269
She became an advocate for victims, but the weight of what she endured never left her. And the community of Perth was also forever changed.
00:07:33.470 --> 00:07:42.029
Before the Morehouse murders, it was seen as a safe, almost sleepy town, far from the infamous crimes that made headlines elsewhere.
00:07:42.329 --> 00:07:51.569
But the Burneys shattered that sense of security. Parents stopped letting their daughters do really anything anymore, and the innocence of the suburbs was gone.
00:07:51.769 --> 00:07:58.149
And Catherine, remember, she had the opportunity to walk away, but she didn't. She chose David.
00:07:58.449 --> 00:08:08.829
She chose the violence. She even chose his name, becoming Catherine Birnie without ever legally marrying him, a sign of just how fully she surrendered her identity to his.
00:08:09.089 --> 00:08:16.389
This is the legacy of Catherine Birnie, not just the horror of crimes, but the reminder that monsters do not always walk alone.
00:08:16.790 --> 00:08:27.310
Sometimes they walk side by side. This has been GBRLIFE of Crimes, part of GBRLIFE Transmissions, and I'm Kaitlyn reminding you that understanding the darkness helps us appreciate the light.
00:08:27.610 --> 00:08:32.570
Join me next time as we uncover another case that challenges everything we thought we knew about the criminal mind.
