The “Invisible” Killer Who Evaded the FBI for Decades

Caso Narvarte: five executions with signs of torture that do not fit a robbery

The clan that killed in broad daylight: The true story of Arquímedes Puccio A family that went to church on Sundays, swept sidewalks, and organized dinners in San Isidro operated a kidnapping and murder business from their basement. For three years, no one in the neighborhood suspected anything. How is it possible that a man with a diplomatic career, connected to state intelligence, kept three corpses and a woman chained while his son watched movies upstairs? In this episode, we explore the investigation that led to the capture of the most sinister clan in democratic Argentina: the contradictions between what the family claimed to know, the confessions of the accomplices, and what the police found in August 1985. We unravel how Alejandro identified Ricardo Mannochan, why Laborda executed Emilio Nahún without collecting a ransom, and what role an undercover police officer played in protecting Puccio for years. How much institutional protection surrounded this operation? Victim: Ricardo Mannochan, Eduardo Aulet, Emilio Nahún Date: July 22, 1982 to August 23, 1985 Location: San Isidro, Buenos Aires, Argentina Status: Resolved; life sentences executed; unresolved institutional details - Three victims murdered in three years; a woman chained in a secret basement behind a wardrobe; police found a bucket, cot, and straw. - Puccio denied everything until conviction in 1995; Laborda confessed that he recruited, manipulated, and defrauded money; unresolved contradictions about economic distribution. - An undercover police officer warned Puccio of a monitored delivery operation; allowed the clan to prepare a defense; the informant's identity was never revealed. - Daniel Puccio arrived from New Zealand with a letter from his father describing the business as "an industry without chimneys"; arrested in Brazil in 2019 with a false document; successful escape without public explanation.

The “Invisible” Killer Who Evaded the FBI for Decades

Truck Painter Passes Polygraph as Detectives Search Nineteen Years for Wrong Profile: The Green River Murders of Gary Leon Ridgway Five young women found strangled in the Green River within two months of summer nineteen eighty-two. The killer lived next door, paid taxes, attended church, and painted trucks for thirty years. No one suspected him because investigators were hunting for someone smarter than he actually was. We explore the impossible timeline: how a man with an IQ of eighty-two evaded fifty detectives and thirteen thousand suspects across nineteen years, why Rebecca Garten's attempted strangulation report was never connected to the murders, and why a voluntary saliva sample collected in nineteen eighty-four sat in evidence for fourteen years before DNA technology could speak the truth it always contained. Victim: Wendy Leigh Field (first confirmed victim, July 8, 1982) Date: July 1982 - November 2001 (arrest) Location: Green River, King County, Washington Status: Forty-nine confirmed victims; guilty plea two thousand three - Ridgway passed a nineteen eighty-four polygraph despite Rebecca Garten positively identifying him as her attacker in photographs - Detectives dismissed him because his psychological profile did not match the FBI's prediction of above-average intelligence and sophistication - Ted Bundy from death row identified the corpse-abuse pattern in nineteen eighty-four letters, but this knowledge arrived too late to refocus the investigation - Detective Tom Jensen preserved a saliva sample that no laboratory in nineteen eighty-four could process, betting on future technology that would arrive exactly fourteen years later Gary Leon Ridgway, Green River Killer, Seattle Washington, nineteen eighty-two, DNA technology, homicide investigation, serial killers, psychological profiling, forensic science, unsolved mysteries, true crime English To listen to this podcast ad-free and access premium episodes, try our subscription with a 14-day free trial at obomedia.com. © 2026 OBOMEDIA.

Clan Puccio: the family that turned kidnapping into a criminal enterprise within their own home

The nanny who wanted to steal her identity: The murder of Rachel Barber An anonymous call offered easy money. Rachel Barber, a 16-year-old dancer, accepted without telling her mother. Hours later, she disappeared. What the family discovered in her killer's notebook revealed a documented obsession: Caroline Reed not only wanted to kill her, she wanted to become her. In this episode, we explore how a trusted nanny spent years gathering personal data, how the police took 48 crucial hours to act, and how a phone cord and a notebook with Rachel's complete biography exposed an identity theft plan that almost worked. How does someone who was part of the family turn into a killer? Victim: Rachel Barber Date: March 1, 1999 Location: Melbourne, Victoria, Australia Status: Sentenced to 20 years; parole January 2015 - Caroline obtained Rachel's number by calling twice with fake money offers: modeling and "psychological study." - In her home, there were photographs of Rachel, family data lists, and a notebook where she described the victim as "pure and perfect" while depreciating herself. - The body was transported in military bags and buried on a family farm; the phone cord was still around her neck when it was found. - In prison, Caroline lost 30 kilos, dyed her hair blonde, and straightened it to physically resemble Rachel, continuing the identity theft plan even behind bars.

The Perfect Crime That Failed Because of a Stone in the Acid

Man Confesses to Dissolving Body in Acid, Certain No Court Can Convict Without a Body: The Murder of Olive Durand-Deacon February 1949, London. A sixty-nine-year-old widow vanishes after leaving her hotel with a businessman offering to help develop her business idea. What police discovered in the warehouse would expose a calculated system of murder-one that had worked flawlessly five times before. A pathologist's examination of two hundred kilos of greasy soil revealed what sulfuric acid could not destroy, unraveling a killer's fatal miscalculation. In this episode, we explore how John George Haigh built a method that eliminated bodies but left behind systematic evidence: forged documents, jewelry sales witnessed by dealers, bloodstains on warehouse walls, and the meticulous planning of a con artist turned serial killer. How did a pathologist named Keith Simpson identify a victim from fragments the acid was supposed to obliterate, and why did Haigh's confidence in the absence of a corpse become his undoing? Victim: Olive Durand-Deacon Date: February 18, 1949 Location: South Kensington, London / Crawley, East Sussex, England Status: Solved - A killer voluntarily accompanied the victim's friend to report her disappearance to Scotland Yard the very next day - Haigh confessed without pressure, believing sulfuric acid had made conviction impossible without a body - Pathologist Keith Simpson discovered a gallstone the size of a cherry, preserved by protective fat tissue the acid could not penetrate - Olive's dental prosthesis and bone fragments allowed definitive identification, collapsing Haigh's entire defense strategy Olive Durand-Deacon, John George Haigh, London serial killer, sulfuric acid murder, 1949, forensic science, criminal minds, pathology, unsolved vanished, true crime English To listen to this podcast ad-free and access premium episodes, try our subscription with a 14-day free trial at obomedia.com. © 2026 OBOMEDIA.
