    The carpet that disappeared: Diomedes and the buried secret: The homicide of Doris Adriana Niño

    In the early morning of May 15, 1997, a man in a yellow sweater throws a body wrapped in a raincoat into a thicket on the outskirts of Bogotá. Three farmers see everything. But when the police arrive, no one asks about the carpet that disappeared from the apartment where it all happened.

    In this episode, we explore the contradictions that condemned singer Diomedes Díaz: a death that changed causes between autopsies, fluids from three men found on the corpse, and a note with the exact address kept in the pocket of an engineer who loved an idol too much. How did six years in prison turn into three and a half years of freedom?

    Victim: Doris Adriana Niño
    Date: May 14-15, 1997
    Location: Bogotá, Colombia
    Status: Closed case with reduced sentence

    - Mechanical asphyxia confirmed in second autopsy after two years; first autopsy concluded overdose.
    - Fluids from three men found on the corpse; post-mortem abuse never formally investigated.
    - Carpet from the apartment replaced without authorization from the record label before forensic inspection.
    - Diomedes released after 3 years and 7 months of a 6 and a half year sentence; died in 2013 as a popular idol.

    System Releases Him Thirteen Months Before He Murders Three: The serial murders of Nicole Paterson, Margaret Josephine Mack, and Mersina Halvagis

    September 1996. A man with sixteen documented sexual assault convictions walks free from a Victorian prison. Psychiatric records flag him as high-risk. No one stops him. Thirteen months later, a woman is found dead with injuries Australian forensic science had never documented before.

    In this investigation, we examine how Peter Dupas moved through decades of institutional cycles-arrested, convicted, released, reoffended-each time the system processing him without breaking the pattern. We reconstruct the three murders that finally caught him, the forensic signatures that linked them, and the central question: why did a system with complete knowledge of his escalating violence repeatedly set him free?

    Victim: Nicole Paterson, Margaret Josephine Mack, Mersina Halvagis
    Location: Melbourne, Victoria, Australia
    Date: 1997-1999
    Status: Convicted; three life sentences

    - A man released in September 1996 with sixteen prior sexual assault convictions and documented psychiatric warnings against release
    - A forensic signature so specific-mutilation of breasts and surgical placement-that it appeared in case files as unprecedented in Victorian records
    - Investigators discovered he had called Nicole Paterson's phone fifteen times in forty days while denying ever knowing her
    - His grandfather's grave was 128 meters from Mersina Halvagis's body, and he rented a hotel directly across from the cemetery where she was found

    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.

    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

    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.

    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.

    Victim: Peter Walker, Christopher Donn, Perry Bradley III, Andrew Collier, Emmanuel Spiteri
    Date: March-June 1993
    Location: London, England
    Status: Solved

    - Colin Ireland planned his first murder on New Year's 1993 with the stated goal of becoming a serial killer before December
    - He called The Sun newspaper after killing Peter Walker, not to confess but to warn that the victim's dogs needed rescue
    - The killer peered through a window frame to watch emergency responders arrive, leaving the only fingerprint evidence across four crime scenes
    - Emmanuel Spiteri refused to reveal his bank PIN under torture, preventing the killer from completing his signature ATM withdrawal

    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

    Couple Crosses Six States Leaving Eight Dead in Fifty-Three Days: The Murder Spree of Alton Coleman and Debra Brown

    On May 29, 1984, nine-year-old Bernita Wyatt vanished from Kenosha, Wisconsin. Within weeks, her disappearance would trigger the largest federal manhunt of the decade, spanning six states and involving 150 agents. The question investigators could not answer: how did the killers always stay one step ahead?

    In this episode, we trace the fifty-three-day rampage of Alton Coleman and Debra Brown-a serial killer and his accomplice who murdered at least eight people, injured dozens, and robbed more than twenty victims while evading capture. We explore the forensic evidence that linked cases across state lines, the psychological profile that predicted their capture, and the debate over responsibility that would divide courts for years. What made the FBI break its own rules and create an eleventh spot on its most wanted list for the first time in history?

    Victim: Bernita Wyatt, Annie Hilliard, Tamika Turks, Donna Williams, Virginia Temple, Rachel Temple, Marlene Walters, Eugene Scott
    Date: May 29 - July 20, 1984
    Location: Wisconsin, Illinois, Indiana, Michigan, Ohio
    Status: Both perpetrators arrested and convicted

    - Nine-year-old Bernita Wyatt disappeared on the same day her abductor appeared in court for raping a fourteen-year-old girl
    - A bracelet from one victim was found at the crime scene of another, linking murders across three different states
    - Six-year-old Raymond Temple survived by hiding in a bathroom while his mother and sister were murdered in the same house
    - Coleman carried a hidden knife at arrest with blood matching a fifteenth victim not in the initial count
