Throw yourself or I’ll throw you: The secret of the seventh floor

The unlocked door and the invisible predator

The unlocked door and the invisible predator: The murder of Briana Denison A young woman sleeping on a couch, just meters away from her friend. An unsecured glass door. At 4 a.m. on January 20, 2008, Briana Denison disappears from a house in Reno without leaving an audible trace. How does a man enter an occupied home, abduct his victim, and vanish in silence? In this episode, we explore three previous identical attacks linked by DNA, a gray Toyota Tacoma with incriminating clues, and another woman's underwear found alongside the body. A pattern of trophies, unexplained nighttime absences, and a girlfriend who breaks her alibi reveal how a pipe installer operated as a silent predator in the university shadows. Victim: Briana Denison Date: January 20, 2008 Location: Reno, Nevada Status: Guilty - Life imprisonment + death penalty (2010) - James Michael Biela enters the house without forcing the lock; visible orange socks under branches confirm intent to conceal, not accidental entry. - Four victims linked by DNA in 3 months; the fourth attack occurred earlier, but stolen underwear appears alongside Briana months later. - Biela's girlfriend discovers women's clothing in his truck during a trip to Sierra Washington; her testimony destroys the only defense of an alibi. - The underwear found on the body did not belong to Briana; the origin and purpose were never publicly resolved, suggesting prior trophy behavior.

Natalia: five profiles, a killer State

Natalia: five profiles, a murderous State. The case of Natalia Melman, the teenager who disappeared. February 3, 2001. A 15-year-old student leaves two bars in Mar del Plata and never returns. Five distinct genetic profiles will appear on her body. The same police officers who led the search were her murderers. A forensic investigation reveals an institutional cover-up so systematic that it took 22 years to achieve definitive sentences. In this episode, we explore the impossible contradictions that define this homicide: how Natalia's body was found 800 meters from an area that the police claimed to have thoroughly searched, why a fifth DNA profile remains unidentified decades later, and how the Argentine State murdered one of its citizens and directed its own investigation. From the prohibition of disseminating images to post-mortem cut nails and a police van repainted white, every detail exposes a perfect crime that was not so perfect. Victim: Natalia Melman Date: February 3, 2001 Location: Mar del Plata, Argentina Status: Multiple convictions; one unidentified fifth suspect - Five distinct genetic profiles on the body, but none of the culprits acknowledged their actions or apologized. - The body was found exactly 800 meters from the area that the police claimed to have meticulously combed for days. - Sergeant Ricardo Panadero remained active in the police force for seven years after his DNA matched 97 percent with forensic evidence. - A law reduced El Gallo's sentence from 19 years to 4 years, while the three police officers received reductions that sparked Saturday marches for years.

Two bodies, three convicted, four DNA profiles unanswered.

Two bodies, three convicted, four DNA profiles unanswered: The homicide of Marina Menegaz and María José Coni Two young Argentine women wrapped in plastic, found 40 meters apart with two days between their deaths. When the police discovered Marina on February 25, 2016, María José was possibly still alive somewhere nearby. A forensic mystery that begins with a decision to hitchhike and ends with an investigation riddled with inconsistencies. In this episode, we explore the contradictions surrounding the case: the toxicology revealing benzodiazepines in both victims, the inexplicable change in the date of death of María José between autopsies, and the three genetic profiles found at the crime scene that were never identified. Do three convicted individuals really explain everything that happened that night, or does the true criminal network remain hidden? Victims: Marina Menegaz and María José Coni Date: February 22-27, 2016 Location: Montañita, Santa Elena Province, Ecuador Status: Convicted; case technically open - Benzodiazepine administered to both victims nullifies consent explanation in taxi - Second autopsy changed María José's death from February 22 to 25 without public justification - Three unidentified DNA profiles found at the scene not linked to any of the convicted - Femur fracture in María José incompatible with confessed version of crime in single dwelling Marina Menegaz, María José Coni, Ecuador 2016, homicide, serial killer, forensic, mystery, investigation, true crime, criminal minds, true crime Spanish If you want to listen to this podcast ad-free and gain access to premium episodes, we invite you to try our subscription with a 14-day free trial at obomedia.com. © 2026 OBOMEDIA.

The phone that confessed a crime in the desert

The phone that confessed a crime in the desert: The murder of Leslie Palacio A disposable phone lights up in Valley of Fire, Nevada. A voluntary confession to a friend. A request for gasoline to avoid cameras. The suspect was never apprehended. How is it possible that a man who confessed to a murder to a witness, left video of his crime, geolocation, and DNA, has been on the run for over four years? In this episode, we explore the clues that point directly to Eric Rangel: the neighborhood video that captures the transfer of Leslie's body in the trunk, the blood in his room, and the recorded confession that was never enough. While the police waited 72 hours, the family investigated their own death. The question that haunts the case: why does the cause of death remain undetermined three years later? Victim: Leslie Palacio Date: August 28-29, 2020 Location: Las Vegas and Valley of Fire, Nevada Status: Suspect at large; accomplice partially convicted - Neighborhood video documents the transfer of the lifeless body in the trunk at 6:30 in the morning - Eric's disposable phone lights up in Valley of Fire the same day, with a recorded verbal confession - Cause of death remains officially "undetermined" despite toxicology pending since 2020 - Eric's father served only 8 months of a 728-day sentence for complicity Leslie Palacio, Las Vegas murder, 2020, forensic investigation, unsolved mystery, criminal truth, homicide, true crime, disappearance, incomplete justice, true crime Spanish 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.

Throw yourself or I’ll throw you: The secret of the seventh floor

Throw yourself or I'll throw you: The secret of the seventh floor: The murder of Iván Ortiguera in Pergamino, Buenos Aires Iván Ortiguera, 16 years old, falls from the seventh floor at 9:40 AM on January 6, 2012. His boyfriend Fabián Núñez, the father of his girlfriend, admits to having shouted "throw yourself or I'll throw you" moments before. The problem: the autopsy reveals that the boy fell unconscious, making it impossible for him to jump voluntarily. How does someone who is unconscious commit suicide? In this episode, we explore the deadly contradiction that destroys the official version. Two neighbors describe from the balcony how Núñez holds Iván by the neck with half of his body outside the window, blood on his head, with no reaction whatsoever. The facial fractures prior to the fall, Tamara's scream ("don't hit him anymore"), and the forensic reconstruction reveal a brutal chase inside the apartment. Why did it take only 48 hours to release the main suspect? Victim: Iván Jesús Ortiguera Date: January 6, 2012 Location: Pergamino, Buenos Aires, Argentina (Goyenas Salas 440, 7th floor) Status: Qualified homicide with premeditation. Life imprisonment (February 2014). - Neighbors Rosario and Norma heard glass breaking and the command "throw yourself or I'll throw you" from the adjacent room. - The autopsy determined fractured jaw and nasal septum before the impact, evidence of prior violence and loss of consciousness. - Núñez admitted in an interview with Clarín that he hit Iván but maintains that he jumped voluntarily. - Forensic Director Marcelino Cotier reconstructed a push by an external agent after a chase and cornering.
