In July 1995, 15 year-old Elyse Pahler vanished from her home in Nipomo, California. For eight long months, her family searched for answers unaware that she had been lured into a dark eucalyptus grove by three local teenagers she trusted.

​Driven by a delusional obsession with death metal and dark occultism, the boys believed sacrificing an innocent girl would grant their band artistic power and fame.

On a quiet Friday night in September 2006, 16-year-old Cassie Jo Stoddart was house-sitting in rural Pocatello, Idaho. What began as a peaceful evening turned into a real-life slasher film when two of her classmates executed a meticulously planned murder and recorded their intentions on camera.

On May 31, 2014, a 12 year-old girl crawled out of a Wisconsin forest with 19 stab wounds, leading police to a shocking realization: the attackers were her two best friends, acting on orders from a fictional internet monster. In this episode we break down the horrifying reality of the Slender Man stabbing, tracing the origins of a digital myth, the mechanics of shared delusion (folie à deux), and the chilling police interrogations that exposed an untreated mental health crisis.

On August 28, 2003, in Erie, Pennsylvania, a quiet pizza delivery driver walked into a bank with a homemade cane-gun and a massive metal collar bomb locked around his neck. What followed was a live-television tragedy, an impossible scavenger hunt, and a frozen body in a garage freezer that exposed one of the most twisted criminal conspiracies in American history. Join Audrina as we break down the bizarre death of Brian Wells and the mastermind behind it all.

On May 24, 1987, 23-year-old Kenneth Parks walked into an Ontario police station with severed tendons in his right hand, covered in blood, and uttered six chilling words: "I think I’ve killed some people."

Across town, his mother-in-law lay dead and his father-in-law was critically injured. Yet Parks maintained one impossible defense: he was sound asleep during the entire 14-mile drive and brutal attack.

When Court Officer Michael Hart arrived at 36 Brockley Drive for a routine welfare check, he walked into a scene that defied medical science.

Yet forensic evidence revealed a horrifying truth: Peter had been attacked in his sleep hours earlier and his body carried out an entire morning routine purely on automated muscle memory.

Most serial killers leave behind a chaotic trail of passion, rage, or panic. But Israel Keyes operated entirely outside the grid, treating human life as a clinical logistics problem. In our extended season finale, True Crime on the Brain breaks down the terrifying geometry of the modern predator who mapped the United States like a chessboard.

​We dig deep into the chilling anatomy of his "kill caches"

Five-gallon plastic buckets filled with weapons, silencers, and chemicals, buried in the earth years before a victim was ever chosen. From the genesis of his off-grid childhood and elite military training to the stolen lives of Samantha Koenig, Debra Feldman, and Bill and Lorraine Currier, we examine the hyper-focused executive functioning that baffled the FBI for a decade. More importantly, we look at the fatal arrogance that ultimately caused his calculated algorithm to collapse.

​Join us for our final case of the season as we honor the victims and dissect the machinery of a monster before stepping away for a short production break. Settle in, turn the lights down, and listen close.

​True Crime on the Brain will return for Season 2.
