Descripción

The night Mario did not commit suicide: forensic contradicts police: The homicide of Mario Biondo in Madrid, 2013 Early morning of May 30, 2013. A domestic worker discovers Sicilian cameraman Mario Biondo hanging in his apartment, which was locked from the inside. A Spanish forensic expert instantly certifies it as suicide. But eight years later, an Italian judge declares it was murder and that the body was positioned to simulate voluntary asphyxiation. How is it possible for two nations to reach opposite conclusions? In this episode, we explore the contradiction that unravels the case: the position of the body incompatible with suicide, two unknown phones connected to the wifi that night, and 196 gigabytes deleted post-mortem from his wife's device. Raquel Sánchez Silva, the Spanish host, changed her statement about Mario's drug use, denied knowing a "Nacho Leonardi" whose messages appear on his backup, and allowed television cables to disappear without investigation. Who had access and a key to enter and exit without leaving a trace? Victim: Mario Biondo Date: May 30, 2013 Location: Calle de la Magdalena, Madrid, Spain Status: Closed without charges, homicide confirmed by Italian magistrate - The third exhumation in 2018 revealed a left cranial blood clot that the first autopsy never reported due to not opening the skull, violating forensic protocol. - The laptop password was changed at 2:41 AM on May 31 while Raquel claimed to be at the forensic institute, with no record of her computer expert cousin's presence. - Two unknown mobile devices connected to the home wifi that morning and accessed Facebook and Twitter without the Spanish police investigating their identity. - Television cables detected as missing in crime scene photographs but never pursued; criminologists point to them as a probable method of strangulation.

The brother who posted a goodbye while the police were searching for him

The brother who posted a goodbye while the police were searching for him: The murder of Amber Gibson in Hamilton, Scotland Cathkin Glen, November 26, 2021, past 9:30 PM. Cameras capture a 16-year-old girl entering the park with her brother. Ninety minutes later, he exits alone: dirty, covered in mud. Three days later, her body is found strangled. The most disturbing contradiction: while the police were searching for him, he posted a tribute on Facebook saying how much he loved her. In this episode, we explore how Conor Gibson destroyed his own alibi with WhatsApp messages asking for "help" and notifying that he "had already solved the problem," how his DNA on Amber's clothing and his blood on his jacket linked him directly to the scene, and how a second DNA profile - that of hitman Steven Cingano - revealed that Amber was attacked twice by different men before dying of asphyxiation. How did a system that had known about Conor's violence since childhood allow him to be alone with his sister? Victim: Amber Gibson Date: November 26-28, 2021 Location: Cathkin Glen, Hamilton, Scotland Status: Conor Gibson, life imprisonment (minimum 22 years); Steven Cingano, 9 years; Jamie Stars, 10 and a half years - Amber's Samsung phone was found broken into three pieces in the park, evidence of deliberate destruction of communications. - Conor sent a message to Amber after she was already dead, asking if she was okay and pretending ignorance. - His internet search history recorded instructions on how to prevent the police from checking his browsing history. - A third attacker, Jamie Stars, was identified by Amber in June 2021; her recorded statement, presented after her death, was key to convicting him to 10 and a half years.

The chemist who killed with impunity for twelve years

The chemist who killed with impunity for twelve years: The feminicide of María José and Miguel Cortés Miranda An apartment in Iztacalco held five skulls, crime journals, and remains of at least twenty women for twelve years. Families reported the name of the same man over and over to the prosecutor's office: Miguel Cortés Miranda, a trilingual chemist, charismatic, who operated since 2012. How did this serial killer survive while justice ignored reports with addresses and testimonies? In this episode, we explore Miguel's hunting pattern through the Fundación Igualdad Animal, his veiled poems on Facebook that described crimes, and the documented negligence of authorities who had his name since 2020. From Karen Ornelas in 2012, through Frida Sofía Lima Rivera in 2014, to Viviana Elizabeth Garrido in 2018: ignored victims while he wrote confessions in code that no one deciphered. What allowed a man with unexplained scratches and chemical knowledge to remain free when every detail pointed to him? Victim: María José, 17 years old (trigger crime); identified victims: Karen Ornelas Baltazar, Frida Sofía Lima Rivera, Viviana Elizabeth Garrido, Claudia Andrea, Amairani Roblero Date: April 16, 2024 (arrest); documented crimes 2012-2024 Location: Apartment, Iztacalco, Mexico City Status: Preventive detention, ongoing trial - Five human skulls found in the apartment after the raid on April 16, 2024 - Personal diary documents dismemberment methods and the evolution of crimes since 2012 - Poem "I Will Miss You" published four days after Frida Sofía's last connection on Facebook - The prosecutor's office had the name, address, and testimonies since 2020 but classified the suspect as "unstoppable" Miguel Cortés Miranda, Iztacalco Mexico City, serial feminicide, serial killer, 2024, criminal diary, impunity, forensic, investigation, criminal minds, true crime Spanish If you want to listen to this podcast without ads and have access to premium episodes, we invite you to try our subscription with a 14-day free trial at obomedia.com. © 2026 OBOMEDIA.

The refrigerator that held a blood secret

The refrigerator that held a blood secret: The murder of Natalia Samaniego A refrigerator gifted by a mother becomes a tomb. Natalia's body had been decomposing for eight days when the unbearable smell revealed the crime that almost passed as suicide. How did a killer send messages from his dead victim's phone, promising dinners that would never happen? In this episode, we explore the calculated coldness of a premeditated murder: the handwritten letter signed in blood asking Lucifer to hide the evidence, the videos uploaded to Facebook while the body was decomposing, and the investigation that took over a year to dismantle each lie. A family turned their pain into law; a killer never spoke. Victim: Natalia Samaniego Date: September 1-2, 2018 Location: Posadas, Misiones, Argentina Status: Life imprisonment - December 21, 2021 - A handwritten letter signed in blood and initials requested satanic entities to hide the corpse - found in the apartment. - Juan was active on Facebook uploading videos at 10:40 PM on September 8, while the body had been in the refrigerator for days. - The autopsy confirmed unilateral manual strangulation, ruling out any pact or self-harm that initial reports suggested. - Natalia was diagnosed with schizophrenia but was pharmacologically controlled; domestic violence began in 2015 with extreme jealousy and suicide threats as a control tool.

Victoria Mafra: eight years to reveal the homicide

Victoria Mafra: eight years to reveal the homicide: The disappearance of Victoria Mafra Natalini A 17-year-old student disappears during a school trip in broad daylight with teachers present. Eight years later, her father discovers what the police and forensic experts never wanted to investigate: it was not natural causes. The body is found 1.5 kilometers from where she was last seen, and the official autopsy declares seizures. In this episode, we explore the contradictions surrounding the case: the initial autopsy versus the private expert report that determines mechanical asphyxia, the ignored witness who saw Victoria agitated near the bathrooms, and the evident post-mortem transfer in the deliberate position of the corpse. How do the school, the police, and the experts all fail in the same direction simultaneously? Why is the killer still free? Victim: Victoria Mafra Natalini Date: September 11, 2015 Location: Fazenda Pereiras, Itu, São Paulo, Brazil Status: Case reopened; perpetrator unidentified - The body was found face down with arms intertwined, indicating deliberate post-mortem manipulation and transfer from the crime scene. - The official autopsy concluded natural death due to seizures without active investigation; private experts determined direct mechanical asphyxia, likely manual. - A tractor driver saw Victoria agitated, hitting her legs between 2:30 PM and 3:00 PM; he was interviewed and dismissed by police in 2015, later rescued years after as a key witness. - For two hours, no adult supervised Victoria while she was alone 500 meters away, violating school protocols that later claimed to have been followed.
