Key Discussion Points & Insights

1. Who Was Sarah Gilson?

• [01:52] Lyndon Blake describes Sarah as a relatable, social-media-savvy small-town mom who built an income through TikTok, selling jewelry and bags and sharing moments of daily life.

  • Quote:

    “She was just one of those girls, you know, a country girl, small town girl... very relatable. But she also had this online persona with her husband, Jeremiah Sean Duffy – known online as the Duffs.”
    — Lyndon Blake [01:52]

• Sarah’s first husband, Lyle Landers, reportedly tried to help her leave Duffy on five separate occasions, highlighting a recurrent pattern of abuse.

2. The Viral TikTok & Its Aftermath

• [03:49] Sarah posted a TikTok on July 11th, claiming she was preparing for a Netflix documentary about her “soon-to-be-ex-husband, who I found out was a pedophile.”

• The video went viral and is seen as a dangerous escalation in a volatile situation.

  • Quote:

    “When I did see it, I thought, well, yeah, that's a scary thing to say out loud anywhere, especially about a partner with whom you've had, I'm gonna say, an abusive relationship.”
    — Michelle Laurie [03:49]

• Both hosts agree the revelation, while empowering for Sarah, may have had significant consequences, including risking legal ramifications and personal safety.

3. Timeline of Events Leading to Murder-Suicide

• [04:13] On June 9th, Sean Duffy allegedly inappropriately touched and kissed a young girl while coaching basketball, leading to a police investigation.
• Sarah referenced this incident indirectly (June 20th TikTok: "pray for the victim and her privacy") and subsequently obtained a protective order against Duffy.
• Within weeks, after the protective order and the viral TikTok, Sean Duffy killed Sarah and died by suicide.
  • Quote:

    “So when this little girl and her parents complained… Sean Duffy at that point was under investigation. Shortly after this incident on June 9th is when Sarah got her emergency protective order... And in that moment in June, you felt like, okay, the ball is rolling now.”
    — Lyndon Blake [04:52]

4. Impact on Family and Children

• [07:02] At least one of Sarah’s children was home during the murder, and her young son made the 911 call.
  • Quote:

    “It was her son, her juvenile boy, that made the 911 call saying that... his mom had been shot. You know, that poor boy...I just don't ever—I don't understand that. I will never understand you just thinking, 'Oh, the kids, they'll be okay.' Like, that little boy... he saw his mom dead, you would assume.”
    — Lyndon Blake [07:02]

5. Prevalence and Patterns of Domestic Violence "Family Annihilation"

• [07:57] Michelle Laurie cites a chilling statistic: since 2020, in the USA, a family annihilation murder (one person kills their whole family) happens on average every five days.

  • Quote:

    “Since 2020, on average, once every five days, there's a family annihilation murder in the US…where one person murders their entire family — every five days.”
    — Michelle Laurie [07:57]

• Lyndon emphasizes the importance of consistent support for people in abusive relationships, even if it feels "annoying."

  • Quote:

    “If you feel like you have a friend that is not in a good relationship…keep being consistent and keep being annoying. Like, don't give up. Because you just never know…”
    — Lyndon Blake [08:26]

6. Social Media’s Role and the Cycle of Humiliation

• The hosts discuss how humiliation, especially public humiliation via social media, can be a trigger for violent abusers.

  • Quote:

    “We know that about these kinds of offenders is a lot of the times it is humiliation that triggers them.”
    — Michelle Laurie [08:56]

• Ironically, Sarah’s viral TikTok about "the Netflix documentary" may in fact become just that, due to the wealth of footage and coverage.

  • Quote:

    “This will be a Netflix documentary and they have so much footage of them both.”
    — Lyndon Blake [09:19]

This is Australian True Crime International with Michelle Laurie. Just days before she was killed, Sarah Gilson posted a TikTok saying she was preparing for the day Netflix made a documentary about her soon to be ex husband after she discovered he was a paedophile. Twelve days later, police allege her estranged husband, Jeremiah Sean Duffy, shot and killed Sarah before taking his own life. Today we're joined by investigative journalist and that's so Criminal host Lyndon Blake to unpack the case. This is Australian True Crime. We acknowledge the traditional owners of the land on which this podcast is created, the Wurundjeri Woi Wurrung People of the Kulin Nation and a warning. This episode of the podcast contains graphic descriptions of violence.

[Lyndon Blake]

She was a girl that was a mom, she was a wife, and she loved just using social media. I feel like she was just one of those girls, you know, a country girl, small town girl outliving in Oklahoma. And she would use TikTok as a way to make income and she would sell jewelry and bags and she'd be like, look at this bag. And I love the color of this bag. It really goes with everything. I mean, she just seemed very relatable. But she also had this online Persona with her husband, Jeremiah. Sean Duffy, he goes by Sean. That's how he's been identified. Within parentheses. Him and Sarah were known online as the Duffs, but it wasn't always butterflies with them. And a big character in this entire investigation and in telling the world who Sarah was is her first husband, Lyle Landers. And he said, you know, that he Tried to get her Sarah to leave Sha Duffy five times over the course of their marriage. And it's a tale as old as time. And I think because of Sarah Gilson participating in this Netflix documentary trend on TikTok, and kind of, for the first time, really peeling back the layer of, okay, this is my soon to be ex husband. I'm preparing for my Netflix documentary on my soon to be ex husband who I found out was a pedophile. And you were like, whoa, yeah, but this is not. This is not funny. This is not talking about your dog. Or you're like, oh, my gosh. There was some time between when this all happened and when the horrible, tragic situation happened. So she made that TikTok. July 11th is when she made it absolutely viral. TikTok.

[Michelle Laurie]

When I did see it, I thought, well, yeah, that's a scary thing to say out loud anywhere, especially about a partner with whom you've had, I'm gonna say, an abusive relationship, because that's the picture that is being developed by her family and friends. That was a massive thing to say online on the Internet. I suppose I would have been more concerned about legal ramifications.

[Lyndon Blake]

But even so, that was July 11th.

[Michelle Laurie]

Yeah.

[Lyndon Blake]

So on June 20th, I mean, she got pretty vulnerable, too. And you. She's talking about that she's focused on her family, and that's her sole focus and her family's only priority. And that let's all remember to pray for the victim and her privacy. But. So it seems like the last weeks of Sarah Gilson's life is when she started putting the dirty laundry out there.

[Michelle Laurie]

Absolutely.

[Lyndon Blake]

And getting the courage up, which is risky and very vulnerable.

[Michelle Laurie]

What was the incident? What sparked all of this?

[Lyndon Blake]

So Sean Duffy, this basketball coach, not affiliated with the school or anything, coach little girls basketball. And there was this incident back on June 9th. There was this basketball tournament, and Sean was obviously coaching there. And this young basketball player and one of her parents went to the Owasso police department to report harassment, that Sean Duffy had inappropriately touched her and kissed her during a basketball tournament game at an elementary school. And that's what I believe Sarah was referring to in that June 20 TikTok when she said, pray for the victim. Pray for her family as well. So when this little girl and her parents complained and said that this man, this grownup man, inappropriately touched this little girl, a juvenile police were able to figure out that similar conduct involving the same little girl was reported to have occurred over an extended period of time. Multiple jurisdictions and states that this is this Poor, poor girl. And Sean Duffy at that point was under investigation. Shortly after this incident on June 9th is when Sarah got her emergency protective order. So Sean Duffy could not come within a hundred yards of her, of her house. And there was no exceptions to that. So he had to stay away. And in that moment in June, you felt like, okay, the ball is rolling now. She's going through with this. She got the protective order. She's going to get away from Sean. And that's when she made that. TikTok was not but two weeks after that that the 911 call came through. You hear the audio. There's allegedly a woman screaming on the audio. And when police got there, they found both Sean Duffy and Sarah Gilson dead.

[Michelle Laurie]

At least one of her children was in the house at the time, wasn't it?

[Lyndon Blake]

That's what the reports are saying. Multiple reports. I'm not going to say all of them because some of them won't obviously identify a child. But, yeah, I mean, if you're looking at this, it was her son, her, you know, juvenile boy that made the 911 call saying that, you know, his mom and stepfather, like, his mom had been shot. You know, that poor boy. And those kids, and especially the ones that were at the house, the boy that was at the house. I mean, why would you want someone to live the rest of their life with that imagery in their head and that baggage and that trauma? I just don't ever. I don't understand that. I will never understand you just thinking, like, oh, the kids, they'll be okay. Like, that little boy will pray's gonna be okay. But, like, that's. He saw his mom dead, you would assume.

[Michelle Laurie]

I don't think he. That Duffy was thinking anything about the kids. But I read an incredible statistic recently about the US because obviously I'm so focused on crime stats from Australia and specifically about domestic violence. But I read that since 2020, every, on average, once every five days, there's a family annihilation murder in the US that is where one person murders their entire family every five days.

[Lyndon Blake]

The point I make when I talk about this is if you feel like you have a friend that is not in a good relationship and you feel like you're being annoying checking in or they try to block you out of their life, it's almost like, keep being consistent and keep being annoying. Like, don't give up. Because you just never know what situation. And in this case, it seems to have been that police report. Like, what situation is gonna make that person that has shown bad patterns. Snap.

[Michelle Laurie]

Well, and also the TikTok. I mean, the TikTok was humiliating and we know that about these kinds of offenders is a lot of the times it is humiliation that triggers them. And of course, the great irony is not only when I first saw it, I thought, yeah, she's right, that would be a great Netflix documentary. That is a classic Netflix documentary. And now probably will be Linden now.

[Lyndon Blake]

This will be a Netflix documentary and they have so much footage of them both.

[Michelle Laurie]
