  • Hidden Pyrex, Hidden Poison: How a Son‑in‑Law Slow‑Killed Kimberly Green

    Hidden Pyrex, Hidden Poison: How a Son‑in‑Law Slow‑Killed Kimberly Green

    Hidden Pyrex, Hidden Poison: How a Son‑in‑Law Slow‑Killed Kimberly Green

    A Pyrex casserole dish sealed and stuffed into a four‑inch gap in a porch foundation held three tablespoons of pale gray powder; that dish belonged to a woman who died eleven days earlier with no toxicology done. How did hidden powder in a familiar kitchen vessel get there, and what did it mean for Kimberly Green’s unexplained decline?

    In this episode, we follow the timeline from Kimberly Green’s gradual symptoms - fatigue, 11‑pound weight loss, peripheral neuropathy and hospital admission - through the discovery of the sealed dish and the clinicians who began to question the cause of death. Could routine casseroles and soups delivered by a trusted son‑in‑law be the missing piece?

    Person: Kimberly Green
    Date of death: November 28, 2014
    Discovery date: December 9, 2014
    Location: Crestline Drive, Harmon Falls, Pennsylvania
    Doctor: Alan Marsh

    - Three tablespoons of pale gray powder were found inside a sealed Pyrex dish tucked into a four‑inch gap in the porch foundation.
    - Kimberly Green died at age 62 on November 28, 2014, with cause listed as probable cardiac arrhythmia secondary to metabolic disorder.
    - Kimberly had worked 31 years as an office manager and turned 62 in August 2014.
    - By September 2014 she had lost 11 pounds and by October was hospitalized for approximately four days.
    - Thomas Long, her son‑in‑law, had worked on Kimberly’s house in 2008 and 2011 and had been bringing her casseroles and soups two to three times a week.

  • The Dry Circle: How a Cup Exposed a Jailhouse Poisoner

    The Dry Circle: How a Cup Exposed a Jailhouse Poisoner
    2026/08/05
    The Dry Circle: How a Cup Exposed a Jailhouse Poisoner

    A plastic cup left on a frozen grate at six a.m. revealed a dry circle in twenty-nine-degree frost - proof it had been set down after the cold settled. Eleven days later a twenty-six-year-old woman, Angela Hunt, was dead in a county detention facility; who placed that cup and why would become the key to a secret pattern of slow poisoning?

    In this episode, we lay out the timeline, the custody conditions, and the medical and investigatory choices that connected a broken vending machine, manual coffee deliveries, and a handwritten note that refused to close a death certificate. How did routine corrections work and toxicology converge to expose repeated arsenic dosing?

    Person: Angela Hunt
    Age: 26
    Location: Tanner County Detention Center
    Date of death: November 7, 2019
    Toxicology finding: Arsenic with repeated sublethal doses and a larger dose 12-18 hours before collapse

    - A plastic cup was photographed at 6:00 a.m. on a grate with surrounding frost at 29°F, and the concrete beneath the cup was dry.
    - Angela Hunt was held in a protective custody corridor for 31 days prior to her death while preparing to testify on November 19.
    - The vending machine in the protective custody corridor was out of service from October 14 to November 4, requiring manual coffee deliveries from the break room.
    - Corrections officer Roy Boyd worked 61 of Angela Hunt’s 82 overnight shifts, per the assignment log.
    - The medical examiner, Dr. Kenneth Reed, underlined "No tox screen ordered" and refused to sign the death certificate until toxicology returned on November 17 showing arsenic.

  • The Label, the Cooler, and the Coach Who Poisoned a Swim Team

    The Label, the Cooler, and the Coach Who Poisoned a Swim Team
    2026/08/04
    The Label, the Cooler, and the Coach Who Poisoned a Swim Team

    A dead man's handwriting tied to an unopened bottle; a name on a label belonging to a woman buried eleven days earlier; and a coach who kept running morning practices thirty feet away. Thallium, a heavy metal no one tested for, showed up in a young swimmer’s urine - how did a poison move through a swim club for months before anyone understood what was happening?

    In this episode, we lay out the chronology from the first symptoms to the lab result that shifted suspicion, following the key people, timelines, and physical evidence to ask: who was exposed, and who was responsible?

    Person: Marcia Crawford
    Date: October 3, 2019 (bottle found)
    Location: Hargrove Aquatic Center, Dellwood, Ohio
    Person: Douglas Osborne
    Date: September 22, 2019 (Marcia Crawford death)

    - The bottle found by meter reader Charles Draper was photographed on October 3, 2019 and later entered as Exhibit Fourteen in a murder trial.
    - Marcia Crawford, age 48, died at home on September 22, 2019; official cause: cardiac arrhythmia secondary to metabolic dysregulation; no autopsy was ordered.
    - The handwritten label on the unopened bottle read "CRAWFORD" in blue marker, written by a man who had been dead for two and a half years.
    - Coach Douglas Osborne, age 39, had kept a soft-sided cooler on deck with individualized recovery drinks labeled with athletes' names for eleven years.
    - Swimmer Owen Beckett, age 22, was admitted to Keller City Regional Hospital seven days after Crawford's burial with vomiting, descending leg weakness, heart rate of 41 bpm, and elevated urinary thallium.
