Three women. Same region. Three years.
Two vanish without a trace.
One is brutally murdered.
All connected by overlapping circles of friends, and in each case, chilling echoes of gunshots and screams.

This is Episode 2 of AI Investigates: Sandrine Jourdan - Reading Between the Lines.

In Episode 1, we introduced Sandrine’s case and the troubling questions around how her disappearance was investigated. Now, we go deeper. This episode is about more than just the overlapping connections between Sandrine, Jennifer Kilkenny, and Tia Landers. It’s also about how Sandrine’s own personal diaries were read by police as “proof” of suicide, and how AI analysis paints a very different picture.

What you’ll hear in Episode 2

• Christine, Sandrine’s sister, recalls how police dismissed her sister’s disappearance from the very beginning as a “walk-off suicide.”

• Graeme Crowley shares his concerns about investigative tunnel vision and how that shaped what evidence was (and wasn’t) pursued.

• We examine the disturbing parallels between three women who disappeared or were murdered in the same small pocket of Queensland, and whether the odds of that being coincidence really hold up.

• Most importantly: we put Sandrine’s diaries through advanced AI tools designed to detect markers of suicide risk, protective factors, and signs of coercion or violence.

And, for the first time, we reveal new information about one of the other women linked to this story, something that never made headlines but changes how her case is understood. You’ll need to listen to the episode to hear that in full.

The Diaries: More Than a Suicide Note

Police claimed Sandrine’s journals showed she was preparing to take her own life. But the AI’s reading tells a completely different story:

• Future planning: school paperwork, Centrelink appointments, travel bookings… commitments stretching well beyond the date she vanished.

• Protective signals: references to surviving for her children and pushing back against “the easy way out.”

• Threat markers: repeated mentions of strangulation threats, sexual coercion, jealousy, stalking, and firearms.

When run through standardised suicide-risk tools, the analysis showed no evidence of imminent suicide planning. Instead, the pattern that emerged was one of danger from others.

This is where the AI changes the story: instead of accepting the “suicide lens,” we see the possibility of homicide, coercion, and connections to known violent offenders in the same area.

Coming Next: Letters and Lies

After Sandrine vanished, two disturbing letters appeared. They were mocking, degrading, and strangely personal. Who wrote them? Were they a taunt, a warning? Or a cover for something darker? In Episode 3, we’ll use AI tools to compare those letters against Sandrine’s own writing and ask: what do they really reveal?

But it’s not just what was in Sandrine’s diaries that matters, it’s what the police failed to do. For nearly two weeks, the public didn’t even know she was missing. A BOLO alert wasn’t sent because officers couldn’t work out how to save a file as a PDF. Requests to triangulate her phone were repeatedly denied, even after police already knew she hadn’t accessed her bank account, seen friends, or turned up at any hospitals. Each delay and dismissal closed doors that might have led to answers. These failures will be unpacked in detail in Episode 3.

This case isn’t just about what happened the night Sandrine disappeared. It’s about how stories are told, by police, by families, and by the words Sandrine herself left behind. When you start reading between the lines, the picture changes.
