About this listen

 Some cases were closed. Others were just buried.

True Crime Coldblood is the podcast that digs into the cases law enforcement left behind — cold cases, unsolved murders, and criminal investigations that never made it to a courtroom. Every episode pulls from court documents, police records, and firsthand reporting to reconstruct what really happened, and why the system failed to find answers.

This isn't true crime as entertainment. It's true crime as accountability. Host Seth approaches each real crime case with the methodology of an investigative journalist — no speculation dressed up as fact, no dramatization for shock value. Just a clear, unflinching look at criminal investigation failures, overlooked evidence, and the people still waiting for justice.

Seth spent years studying criminal justice and has dedicated his work to amplifying cases that deserve a second look. His background gives him the analytical edge to break down complex forensic and procedural details without losing the human story at the center.

True Crime Coldblood is built for listeners who are done with surface-level storytelling. If you want real cases examined with depth and integrity — not just a retelling — this show was made for you.

New episodes drop everyday, running between 18 and 25 minutes. Long enough to go deep. Focused enough to keep you locked in.

  • The former novices who erased Beatriz without a trace

    The former novices who erased Beatriz without a trace

    The ex-novices who erased Beatriz without a trace: The murder of Beatriz Argañaraz

    An apartment painted and fumigated amidst raids. Blood in the pipes, on the walls, in the car. But the body of the missing director never appeared. Two former nun candidates were convicted of murder, but 18 years later they remain on parole and no one knows where they left Beatriz.

    In this episode, we explore the text messages that placed them at the scene, the bruises that betray a brutal fight, and the three-hour gap in their alibis that they never explained. The second raid revealed what they tried to erase: confirmed DNA, but the question that tortures her sister remains unanswered.

    Victim: Beatriz Argañaraz
    Date: July 31, 2006
    Location: San Miguel de Tucumán, Argentina
    Status: Aggravated murder, convicted, body missing

    - Messages between cell phones on July 31: "come early, I have a little gift" / "I'm on my way"
    - Beatriz's blood found in the bathroom, bedroom, sink, pipes, and Ford Orion despite the painting and fumigation
    - Bruises on hands consistent with digging detected by a forensic doctor in both suspects
    - CNG fuel load equivalent to the exact distance to El Cadillal and back

  • The necklace that accused the innocent

    The necklace that accused the innocent: The murder of Karina del Pozo

    An owl necklace abandoned in a ravine north of Quito was the only clue that led investigators to the body of Karina del Pozo, 20 years old, hidden under a log. But the physical evidence tells a different story than the one justice condemned: blood in a car, dirt on clothing, witnesses whose statements changed three times.

    In this episode, we explore how the vehicle's GPS destroyed the initial alibi, why the concentrated blood in the front area does not match who was convicted as the perpetrator, and how two accusers with no physical trace managed to send a third to prison while they themselves carried evidence of the crime.

    Victim: Karina del Pozo
    Date: February 19-20, 2013
    Location: Quito, Ecuador (Llano Chico ravine)
    Status: Convicted; parole in 2023

    - The GPS of Manuel's car records hours stopped in the ravine, but not the stop on Avenida Brasil where Karina supposedly took a taxi.
    - Karina's blood appears on the steering wheel and handles of Manuel's car, areas where the person in front was, not where David was sitting.
    - Manuel changed his story three times during the investigation: taxi, David killed, then that he himself hit Karina with a rock.
    - David obtains parole after 10 years without ever finding his blood, dirt, or belongings of the victim on his body or at his home.

  • The Silence of Lucía: seven years, three judges, one truth

    The Silence of Lucía: seven years, three judges, one truth
    Apr 20 2026
    The Silence of Lucía: Seven Years, Three Judges, One Truth: The Feminicide of Lucía Pérez Montero

    Three men took an unconscious teenager to a medical guard on October 8, 2016. The autopsy revealed a washed body. The first court acquitted them of abuse, calling the victim a "pathological addict" based on private conversations. How is it possible that the system protects the accused before the one who died?

    In this episode, we explore the contradictions that destroyed two trials: the first autopsy that speaks of impalement without evidence, the second that dismisses that hypothesis, and the old rectal injuries that no court managed to date accurately. Matías's message asking for condoms while Lucía was unconscious in her home, against his version of a spontaneous encounter. And how a press conference contaminated the investigation from day one.

    Victim: Lucía Pérez Montero
    Date: October 8, 2016
    Location: Mar del Plata, Argentina
    Status: Confirmed conviction (March 2023); family seeks greater justice

    - Last recorded access to WhatsApp exactly at 10:30 on October 8: the moment Matías picked her up, after which he never wrote again.
    - The first autopsy mentions "impalement" in a press conference; the second autopsy by the Supreme Court completely dismisses it; Dr. Carrizo denies having included that in her original report.
    - 40 grams of cocaine and 250 grams of marijuana found in the truck: confirms organized operation between Matías and Juan Pablo, not a casual sale of 100 pesos.
    - Defense used 150 private WhatsApp conversations to attack Lucía's reputation; the second trial rejected all evidence as gender stereotypes without forensic validity.
