Victoria Natalini: the school trip that ended in a questioned death

The Kabukicho case: obsessive love, violence, and a criminal turned social phenomenon

No body, no forgiveness: the murder that Tucumán could not solve: The disappearance and murder of Beatriz Argañarás On July 31, 2006, a 45-year-old teacher leaves her home for work and disappears without a trace. Blood splatters in a freshly painted apartment, a car filled with fuel, and text messages would be enough to convict two women of murder, but the body would never be found. How do you prove a perfect crime when the victim remains missing? In this episode, we explore the forensic investigation that faced impossible contradictions: alibis that didn’t add up, injuries on hands that spoke of a struggle, and a fuel record that placed the accused exactly on the route to El Cadillal. Susana Acosta and Nélida Fernández were sentenced to twenty years, but decades later they were granted parole without revealing Beatriz's whereabouts, leaving the most disturbing question of Tucumán justice open. Victim: Beatriz Argañarás Date: July 31, 2006 Location: San Miguel de Tucumán, Argentina Status: Disappearance without a body; convicted on parole - The apartment was painted and fumigated between the first and second searches, but Beatriz's blood remained on the bathroom frame, the wall, and the plumbing. - Susana and Nélida filled up with gas twice on the day of the crime; the exact amount matched the trip from the apartment to El Cadillal and back. - Luis Fernández's housekeeper testified that she washed one of his shirts with blood stains on the same July 31. - Both convicted women married in prison as a pact of silence and obtained parole in 2023 and 2024 without revealing where the body is.

The Killer Who Prevented Earthquakes: Herbert Mullin

Man Feeds Two Women Into Industrial Shredder in Basement: The double homicide of Adriana Joiosa and Lidia Hernández Freshly painted walls, the smell of bleach, and in the center of the room, an industrial shredder with remnants of flesh and bone. When investigators opened the basement door in Majadahonda, Madrid, they discovered evidence of two women who had vanished without a trace-one five years prior, the other just days before. The forensic contradiction that would haunt this case for years was just beginning. In this investigation, we explore the impossible collision between a severely mentally ill man and the calculated precision of his crimes: forged documents prepared years in advance, a phone moved across multiple Spanish cities to construct a false alibi, internet searches for cremation methods, and the methodical construction of an industrial disposal system. How could a patient with paranoid schizophrenia-a man known to neighbors for screaming about demons and rituals with dead animals-orchestrate two murders with the cold calculation of a psychopath? Victim: Adriana Joiosa and Lidia Hernández Date: April 2015 (Adriana); circa 2010 (Lidia) Location: Majadahonda, Madrid province, Spain Status: Unsolved (bodies never recovered) - Industrial shredder found in basement contained DNA from both victims mixed together - Bruno's internet history included searches for "cremation," "meat grinder," and "funeral documentation" before the crimes occurred - Adriana's phone continued sending messages and traveling across Spanish cities after she disappeared, with Bruno controlling her digital identity - Bruno submitted forged property transfer documents three years after his aunt vanished, claiming ownership of the building where both victims disappeared Adriana Joiosa, Lidia Hernández, Majadahonda basement murders, 2015, paranoid schizophrenia, industrial shredder, serial killers, investigation, forensic science, unsolved mysteries, homicide, 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.

The Zodiac Who Exposed Himself

Man Reads FBI Manual and Decides to Become Serial Killer That Year: The Murders of Peter Walker, Christopher Donn, Perry Bradley III, Andrew Collier, and Emmanuel Spiteri London, spring 1993. Five men vanish from the same gay bar within twelve weeks. All are found bound, gagged, strangled-scenes so clean they seem unconnected. Then the killer calls the police himself, unprompted, demanding recognition for crimes investigators haven't yet linked. Why would a serial killer volunteer a confession before capture? Explore how Colin Ireland meticulously studied forensic procedures and gay community codes, executed five murders with surgical precision, then destroyed his own perfect crimes by calling the newspapers. Discover the single fingerprint mistake, the fourth victim's refusal to break under torture, and the psychological profile that reveals a man hunting for fame rather than fleeing justice.

Mackenzie Lueck: the planned murder with a secret room

The fall that wasn't: murder in Pergamino: The qualified homicide of Iván Ortiguera A 16-year-old teenager falls from the seventh floor in Pergamino, Argentina. Four witnesses declare that he committed suicide. But the autopsy reveals something impossible: he had facial fractures prior to the fall. How does someone commit suicide who was already unconscious? What seemed like a desperate jump was actually a murder covered up by lies under oath. In this episode, we explore the contradictions that dismantled the first version. We analyze the testimony of two neighbors who saw Fabián Núñez holding Iván by the neck at the window, shouting "Jump or I'll throw you!" We reconstruct the 2014 trial where forensic experts, criminalistics, and forensic psychology converged on an inevitable verdict: what was the true motive behind this crime in the early hours of January 6, 2012? Victim: Iván Ortiguera, 16 years old Date: January 6, 2012 Location: Pergamino, Buenos Aires Province, Argentina Status: Sentenced to life imprisonment for qualified homicide with premeditation (February 2014) - Maxillary and nasal septum fractures documented before impact; forensic expertise incompatible with voluntary fall. - Direct eyewitnesses saw Núñez holding Iván by the neck, with blood on his head and unresponsive, minutes before the fall. - Núñez publicly admitted in a Clarín interview to having hit Iván and uttered the phrase "jump or I'll throw you," but denied having pushed him. - Previous formal complaint for death threats against Iván establishes a pattern of violent behavior and a motive of pathological jealousy towards his daughter.

Stefanie Magón: the impossible fall that challenges the official version

Natalia's refrigerator: crime in Posadas: The murder of Natalia Samaniego On September 10, 2018, neighbors in Posadas detect a putrid smell and call the police. Agents find Juan unconscious next to pills and alcohol. Inside the refrigerator gifted by his mother as a housewarming present: the body of Natalia, wrapped in a blanket. A letter signed in blood is addressed to "Mr. Lucifer." Was it a suicide pact or a premeditated feminicide? In this episode, we explore the contradictions that condemn Juan: the autopsy rules out voluntary suicide (asphyxiation by manual strangulation), messages from Natalia's cellphone sent days after her death, and activity on Facebook while the body was already decomposing in the apartment. The coroner determines that Natalia had been dead for between 8 and 10 days when she was found. How did Juan convince Natalia to move in with him only to murder her? Victim: Natalia Samaniego Date: September 10, 2018 Location: Avenida Santa Catalina, Posadas, Misiones Status: Sentenced to life imprisonment (December 21, 2021) - Letter signed in blood addressed to "Mr. Lucifer" requesting the disappearance of the body, with Juan's initials confirmed by handwriting experts - Juan active on Facebook the night of September 8 at 10:40 PM while Natalia was already dead in the apartment - Messages sent from Natalia's cellphone days after the crime, where Juan pretended to be her partner and invited her mother to dinner - Forensic autopsy rules out suicide pact: asphyxiation by manual strangulation without the victim's voluntary participation Natalia Samaniego, Posadas Misiones Argentina 2018, feminicide, murder, forensic investigation, aggravated homicide, partner violence, criminal minds, justice, Spanish true crime If you want to listen to this podcast ad-free and have access to premium episodes, we invite you to try our subscription with a 14-day free trial at obomedia.com. © 2026 OBOMEDIA.
