Where have all the serial killers gone?

Where have all the serial killers gone?

Author: ABC Australia July 19, 2025 Duration: 32:07

The backpacker killer. The Claremont killer. Ted Bundy. The crimes serial killers commit linger in our memories for decades.

But when was the last time you heard about an active serial killer in the news?

In our final episode of Criminal Psychology, we probe the lead-crime hypothesis, find out about 'chemical castration' and ask — where have all the serial killers gone?

And a heads up that this episode explores some heavy themes including sexual assault, child abuse, suicide and murder. It also contains the names of Aboriginal people who have died. Please take care while listening.

If you've got more questions for our forensic psychiatrist Dr Rajan Darjee, please send them to us! We're going to make a special mail-bag episode featuring your burning true crime questions. Get in touch by emailing us at mind_rn@abc.net.au with the subject line "criminal psychology question".

Ever wondered what's really happening inside your head? Each week, All In The Mind from ABC Australia ventures into the complex landscape of human thought and feeling. This isn't just a dry science lecture; it's a thoughtful exploration of the experiences that shape us, hosted by curious minds who know how to tell a compelling story. You'll hear conversations that bridge the gap between scientific research and the messy reality of daily life, delving into topics as diverse as the mechanisms of memory, the challenges of breaking an addiction, or the ethical puzzles posed by artificial intelligence. The discussions are grounded and accessible, making the inner workings of the brain relevant to anyone interested in health, behaviour, or simply understanding themselves a little better. By tuning into this podcast, you join a community considering how our mental universe influences everything from our personal fitness to our social connections. It’s a weekly opportunity to pause and reflect on the fascinating forces-both biological and psychological-that drive what we do and who we are. The production brings together expert insights with genuine human stories, creating a space where complex ideas about the mind and behaviour are unpacked with clarity and depth.
