Where is Luke Hazelwood? Part Two: Geography, What We Know, and What We Still NeedIn Part Two of our investigation into the disappearance of Luke Hazelwood, we move beyond the timeline and begin examining the geography surrounding the case. Location matters in missing persons investigations. Terrain, access points, transport routes, and environmental factors can all shape what may have happened and where someone might be.In this episode of Exhuming the Truth, we break down the landscape connected to Luke’s last known movements and discuss what the geography may reveal about possible scenarios. We explore what we know so far, what questions remain unanswered, and the critical information still needed to move this case forward.Using a forensic and investigative lens, we analyse the known facts, consider how geography influences search strategy, and discuss why community awareness and information sharing remain essential in cases like this.Someone, somewhere, may hold the missing piece.
The Digital EvidenceIn Part Two of our look into the disappearnce of Theo Hayez, we take a forensic deep dive into the digital trail he left behind.Theo vanished from Byron Bay in My 2019 after leaving the nightclub Cheeky Monkey's . What followed has been described as a questionable series of phone movements toward the remote headland of Cape Byron. But, when we look into the digital forensics, it paints a far more complicated picture of what actually happened that night. In this episode, we talk about Theo's Google Maps navigational data, the digital timeline from device activity, why the "lighthouse theory" and the "drowning theory" don't clock, what the coastal topography has to challenge about what authorities conclude and the digital indicators that suggest Theo may not have been alone. Was Theo Hayez really alone that night?
An 18 year-old backpacker from Belgium comes to Australia for an innocent trip after finishing school. He left Cheeky Monkey in Byron Bay, and his mobile phone recorded every step after that.In this episode of Exhuming the Truth, I break down the disappearance of Theo Hayez, but not just the timeline. I discuss what the digital evidence means, and what it doesn't.

Tribute to Rob Snyder | The Search, The Community, and the TruthIn this special tribute episode of Exhuming the Truth, we honour the life of Rob Snyder and the extraordinary community effort that came together during the search for him.Searches like these are never simple. Behind every public update are countless hours of planning, coordination, and investigation carried out by volunteers, family, advocates, and authorities who refuse to give up on bringing answers home.In this episode, we reflect on the reality of what goes into a missing person search, analysing aerial imagery, reviewing ANPR camera data, exploring remote off-road tracks, documenting and reporting abandoned vehicles, and following up every lead that could bring investigators closer to the truth.We also acknowledge the people who showed up: the searchers, the supporters, the community members who shared information, and those working quietly behind the scenes.Rob was more than a case. He was a person who mattered deeply to many people.This episode is dedicated to his memory and to the commitment that no one who goes missing should ever be forgotten.Listener discretion is advised as this episode discusses missing persons investigations and the emotional realities surrounding them.
Luke Hazelwood was a Father, a friend, and someone to many people.He was last known to be north of Perth in the coastal town of Lancelin, where he was last seen on the 24th of December, 2025. His ex-wife attempted to report him missing on the 26th of December, however, the reports were not taken seriously until some days into January. With the help of Luke's close friends, we analyse his final known movements, combined with the person Luke is to his loved ones to try to determine what went wrong for Luke.Help us find Luke Hazelwood
Missing since January 22, 2025, from South Boulder, Kalgoorlie, Tristan Griffiths’ case has been marked by frustrating gaps from missing CCTV footage to delays in official responses. In Part Two, we break down the critical timeline, the investigative challenges, and the lengths Tristan’s family has gone to keep his story alive.This episode also explores a broader question: when justice is selective, delayed, or incomplete, can it truly be called justice? Join me as we follow the ongoing search for Tristan, highlight systemic issues in missing persons investigations, and examine why accountability matters, not just for one case, but for all.
Mosman Park Tragedy

Mosman Park Tragedy

2026-02-1727:20

In the aftermath of the tragedy in Mosman Park, headlines moved quickly — using words like “monster,” “evil,” and “unthinkable.” But what happens when we stop at outrage? In this episode of Exhuming the Truth, forensic scientist and criminologist Asha Walther examines the structure of murder-suicide through a research-based lens, exploring why the homicide and suicide cannot be separated, why language shapes policy, and why simplistic narratives may prevent us from understanding risk.Drawing on established criminological and psychological research, this episode explores:• The behavioural structure of murder-suicide• The psychology of hopelessness and cognitive narrowing under chronic stress• Caregiver burden and systemic strain• The pressures surrounding Australia’s National Disability Insurance Scheme• Why affluence does not equal immunity• And why contextualising violence is not the same as excusing it This is not an episode about justification.It is an episode about prevention. Because when we reduce complex human collapse to moral shorthand, we stop asking the questions that could protect future families. Every child’s life holds equal weight.Every postcode contains invisible stories.And every word we use shapes what happens next.Listener discretion advised. References& Further Reading(As discussed in this episode of Exhuming the Truth) Arnsten, A.

Forensic red flags, systemic failures, and the evidence that was never testedIn Part Two of our examination into the fatal police shooting of Luke Gilbert, we move beyond headlines and into the forensic and procedural foundations of the case and what happens when those foundations are missing.Despite a coronial finding being handed down, critical evidence in Luke’s death was never independently tested, never fully disclosed, and in some instances, appears to have been altered or withheld entirely. From missing and edited CCTV footage, unresolved ballistic inconsistencies, and misclassified weapons, to allegations of conflicts of interest, unlawful autopsy consent, and failures by oversight bodies, this episode methodically examines the red flags that undermine confidence in the official findings.This is not an episode driven by outrage or speculation. It is driven by evidence, forensic standards, and the legal obligations that apply when police use lethal force. Drawing directly from the coronial record, the concerns raised by Luke’s family, and accepted forensic and investigative principles, this episode asks one central question: can justice exist where transparency does not?Luke’s case is not just about one man or one night; it is about the systems meant to protect truth and what happens when they fail.Correction & ClarificationI want to acknowledge and correct an error made at the end of the most recent episode.When responding to a listener question about Constable Bryce Collins, I incorrectly stated that he was present at the shooting. That was an error.Constable Collins was not present at the shooting. As mentioned earlier in the episode, his involvement relates to looking Luke up and passing information on to a member of the public.Accuracy matters deeply to me, especially when discussing cases that carry so much weight for families and the public. Thank you to those who respectfully flagged this, and I appreciate the continued care and accountability from this community.
In this episode of Exhuming the Truth, we return to the Claremont case to focus on Sarah Spiers and the legal and court processes that shaped, limited, and ultimately complicated the pursuit of justice in her case. Rather than retelling the events themselves, this episode breaks down how the Australian court system operated at the time, why Sarah's case was legally treated differently to the others, and how evidentiary rules, procedural limitations, and the absense of evidence could and could not be argued in court.
Corrie Feehan vanished from Leeman, WA, in April of 2025. In July 2025, we made an initial episode for Corrie and his family, just 12 weeks after he disappeared. Join us in part two, where we share a heartfelt message from his loving family, who are desperate for answers, and learn about the discrepancies in this case and how you can help us get justice for Corrie and his loved ones.
In this episode of Exhuming the Truth, we return to the case of Sarah Spiers, not to rehash the courtroom outcome, but to confront what happened after the verdict. While a conviction was secured, Sarah herself was never recovered, and the effort to find her body quietly lost momentum once the legal process ended.This episode examines the uncomfortable reality that justice is often treated as complete when a sentence is handed down, even when families are left without answers, without remains, and without peace. We explore the systemic failures, the lack of sustained searches, and the human cost of allowing cases to fade once they are no longer legally active.Sarah deserves more than a footnote in legal history. She deserves to be found, acknowledged, and brought home. Until that happens, this case and this conversation is not over.* Includes an audio clip from Sky News - WA Police Commissioner Chris Dawson *

One of Australia's most shopcking miscarriages of justice: the wrongful conviction of Andrew Mallard.In 1995, Andrew was sentenced to life for the murder of Perth jeweler Pamela Lawrence, a crime he didn't commit. For 12 long years, Andrew fought to prove his innocence from within prison. We explore the flawed investigation, the overlooked evidence, and the systemic failures that allowed this innocent man to be imprisoned. Andrew Mallard's story is a lesson in resilience, truth-seeking and the urgent need for reform in Australia.
Rob Snyder left his home address in Melville on Friday the 25th of October heading for the family's second residence in Heron, Perth.

We break down the details of the timeline, what we know so far, and what areas we have covered in day 6 of our active search for Rob Snyder. The family's best chance of finding their beloved Rob lies with community reach. If you or anyone you know reside in the Oakford, Cardup, Mundijong, Jarrahdale, Serpentine area please share the episode as far and wide as possible, so we can broaden our search. Our thoughts and strength are with the Snyder family during this painful period.
Justice for Lisa Mott

Justice for Lisa Mott

2025-11-1119:19

In 1980, 12-year-old Lisa Mott vanished from Collie, Western Australia, and was never seen again. Despite decades of rumours, dead ends, and alleged sightings of a yellow panel van, Lisa has never been found, and no one has ever been convicted. In this episode of Exhuming the Truth, I re-examine the disappearance through criminological theory and forensic science, exploring how investigative biases and regional isolation may have shaped one of WA's most haunting cold cases.
First up we have an Urgent Active Missing Person in Perth's South, Rob Snyder last known location to be travelling east on Thomas Road in Oakford.Please listen to the details at the beginning of the episode and share around, if you are in the area and are interested in joining the search this FRIDAY the 7th of November in OAKFORD please reach out! On this episode of Exhuming the Truth, I examine the pitfalls of psychic intervention in missing person cases and how this interferes with real-life processes.
