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.

This interview was recorded before Graeme's case went to trial. In the time since this recording, Graeme's specific case went to court and resulted in an acquittal. However, the same individual also faced trials over a number of other historical sexual offences against children. The defendant pleaded not guilty to all charges and has maintained his innocence throughout. 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.

Graeme Simpfendorfer spent 27 years in the Victoria Police, leading elite squads in Homicide and Sexual Offences. He was a veteran detective catching predators until a training lecture on grooming behaviours unlocked a trauma he had suppressed for decades. Graeme realised that as a teenager, he had been the victim of the very crimes he spent his professional life investigating.
In this episode, Gary and Graeme discuss the "war of attrition" that followed when a top detective had to report his own abuser. Graeme reveals the clinical reality of recording a sting call and the struggle of wearing a "Batman mask" to survive his trauma.
