Imagine opening your letterbox to a letter from Ted Bundy or a handmade Christmas card from John Wayne Gacy. Forensic psychologist, Dr Jeffrey Smalldon, doesn't have to imagine. He's communicated with some of the most notorious serial killers in American history.

In this episode, Gary and Jeff unpack Gacy’s charm and lures, how predators pass as “normal”, the double homicide that changed Jeff’s life, and what decades evaluating murderers reveal about psychopathy, empathy, and survival on death row.

At 21, Brodie Finegan Forbes found himself in the centre of the sovereign citizen movement, which he calls a ‘decentralised, pseudo-legal cult’.

The combination of a troubled childhood, loss of his burgeoning music career, and societal and psychological pressures led him to 24-hour Zoom ‘echo chambers’ where he learned how to challenge authority, take on judges, and terrorise people with paperwork. He was part of a ‘chosen few’ who had figured out a ‘secret’. At least that's what he thought...

In this episode, Gary chats with Brodie about the lure of the sovereign citizen movement, how he ended up living in a remote Victorian compound, and the bizarre tactics used by the movement to manipulate the law and avoid accountability.

In Part 2 of Gary’s discussion with former detective Dr Vince Hurley and reformed prisoner Claude Robinson on I Catch Killers, the unlikely duo pull back the curtain on a justice system that is failing victim survivors, perpetrators, and the public alike. They argue that the current approach to tackling domestic violence is little more than a "ten-billion-dollar business" that prioritises prison beds over prevention. However, they may have a solution.

As a teenager, Ian Cherrington became fascinated by the psychology of serial killers - a fascination that would shape his entire career. He began as a forensic psychologist studying the minds of serial killers before making an unconventional leap into frontline policing as a detective in the UK. After years investigating homicides and linking crimes across the country, Ian transitioned into counter-terrorism and lone actor threat assessment, positioning himself at the cutting edge of one of modern policing's most pressing challenges.

In Part 1 of his conversation with Gary Jubelin on I Catch Killers, Ian recounts the harrowing case of Robert Black, a paedophile and child killer whose crimes became the catalyst for Ian's decision to join the police. Ian also unpacks the critical psychological differences between serial killers and lone actors.

While he was found guilty of sexual offences relating to four victims, the defendant continues to maintain his innocence and has filed a motion to appeal those convictions.

Unable to grieve while fighting for justice, Kathleen has stepped in where the system failed - organising community walks and personally tracking down overlooked CCTV footage.

In 1974, a 17-year-old girl in Sydney answered the door to a man claiming to be an encyclopaedia salesman who carried nothing with him and left her with a chilling "full body rush" of fear.

Decades later, that woman's daughter - award-winning author Candice Fox - realised this family story aligned with the timeline of two unsolved homicides from the same neighbourhood. Candice details how this personal connection led her to report the encounter to police and attempt her own investigation into the deaths of Lynette White and Maria Smith and how these tragedies formed the inspiration for her new novel.
