  • The Silver Chalice Left by the Rectory: Poison in Communion

    The Silver Chalice Left by the Rectory: Poison in Communion
    26 Oct 2026
    The Silver Chalice Left by the Rectory: Poison in Communion

    A silver communion chalice was found upright in gravel outside St. Hedwig's rectory at 5:50 a.m., immaculate and smelling faintly chemical - and a woman named Lori Vaughn had died in ICU one hundred minutes earlier from acute liver failure with no history of disease. Investigators later found inorganic arsenic in both the chalice residue and in Lori's tissue and hair, raising a single urgent question: was this a one-time act or a pattern of poisoning?

    In this episode, we trace the timeline from Lori Vaughn's daily routines and duties at St. Hedwig's through the discovery of financial discrepancies she reported to Father Russell Tillman, to her hospitalization and the forensic results that linked the chalice to her death - how many doses of arsenic were involved, and who knew what?

    Person: Lori Vaughn
    Date of death: March 14
    Location: Grantley Regional Hospital ICU
    Event: Silver communion chalice found beside rectory door
    Toxicology result: Inorganic arsenic in chalice residue and in tissue

    - Lori Vaughn was twenty-six years old and worked four years as a teller at Aldenmoor Savings and Loan.
    - She served as a Eucharistic minister at St. Hedwig's for two years and walked to church from her Vetch Street apartment.
    - Lori reported small redirected amounts in the parish building fund records to Father Russell Tillman in late February.
    - Lori was admitted to Grantley Regional in acute liver failure on March 13 and died at 4:17 a.m, on March 14.
    - On March 14 at 5:50 a.m., fifteen-year-old Kelly Keller found an immaculate silver chalice in gravel beside the rectory; it smelled faintly chemical and later tested positive for inorganic arsenic.

  • Cedar Paddle, Five Frozen Glasses: The Thallium Trail to Murder

    Cedar Paddle, Five Frozen Glasses: The Thallium Trail to Murder
    25 Oct 2026
    Cedar Paddle, Five Frozen Glasses: The Thallium Trail to Murder

    A county road grader found a cedar board with five glasses of perfectly level, frozen wine on February 11 - each glass later tested positive for thallium sulfate, a rodent poison and a quiet, cumulative killer. How did contaminated wine glasses on a rural road lead investigators from an apparent natural death to a murder trial over a woman named Sherry Stroud?

    In this episode, we follow the trail from a death ruled natural to toxicology results that changed everything, laying out the sequence of symptoms, tests, and discoveries that linked three vineyard owners to thallium exposure - and the question of who had access and motive remains central.

    Person: Dawn Edwards
    Date: February 8 (death), February 11 (paddle found)
    Location: Route Nine near Packer Road; Ridgecrest Cellars four miles east of Millard
    Cause: Thallium exposure identified by heavy metals panel after initial autopsy listed cardiac arrhythmia secondary to autonomic neuropathy
    Case: Exhibit Three - cedar paddle with five glasses testing positive for thallium sulfate

    - Temperature at discovery: 14 degrees Fahrenheit since 9 PM the previous evening
    - Number of glasses found on cedar board: 5, each holding frozen wine and later testing positive for thallium sulfate
    - Vineyard acreage: Ridgecrest Cellars sat on 12 acres owned by Dawn Edwards
    - Timeline of symptoms: Dawn’s complaints began in November; she died February 8 and was buried February 14
    - Number of affected vineyard owners with positive thallium results: 3 (Dawn Edwards, Ted Garver, Paula Neff)

  • Warm Tea for a Dead Teacher: Why He Returned to the Nurse's Office

    Warm Tea for a Dead Teacher: Why He Returned to the Nurse's Office
    24 Oct 2026
    Warm Tea for a Dead Teacher: Why He Returned to the Nurse's Office

    A faintly warm cup of chamomile tea sat in an empty school nurse's office nine days after a beloved third-grade teacher had been buried, and a lab note about elevated urinary arsenic had gone unread - why did someone come back to that room at all? The discovery of that tea and a post-mortem toxicology flag threatens a small town's story of natural causes and opens the possibility of poison and a pattern spanning years.

    In this episode, we follow the timeline from Teresa Sheridan's sudden hospital admission and death to the routine file audit that unearthed the arsenic note, laying out the facts that shifted a closed case into an investigation: who handled her samples, how the death certificate was signed as natural causes, and what one toxicologist's curiosity revealed?

    Person: Teresa Sheridan
    Age: 32
    Location: Dellwood Ridge
    Event: Admission to Linden Valley Hospital on January 5 for acute liver failure; died same day
    Investigator: Toxicologist Marie Whitfield flagged elevated urinary arsenic during a January file audit

    - A ceramic mug with faintly warm chamomile tea was found on a folding table in the school nurse's office on January 14, nine days after Teresa's burial.
    - Teresa had taught third grade at Dellwood Ridge Elementary for seven years and had not missed a choir rehearsal in four years until October when symptoms began.
    - She was admitted to Linden Valley Hospital on January 5 with acute liver failure of undetermined cause and died that same day.
    - A lab technician noted elevated urinary arsenic in the single admission sample; that note remained unread and un-routed for nine days.
    - Toxicologist Marie Whitfield discovered the arsenic flag during a routine State Medical Examiner's Office audit in January, prompting the case to be reopened.
