    The Shoe in the Freezer: How a Fingernail Broke 31 Years of Silence

    The Shoe in the Freezer: How a Fingernail Broke 31 Years of Silence

    A single brown leather flat was found upright on a concrete culvert thirty feet into the trees on February 9, 1993 - and that shoe sat in a garage box for thirty-one years while the woman it belonged to lay forty feet farther inside cottonwoods. What did that upright shoe, a frozen fingernail swab, and one volunteer’s rigid schedule together hide, and how did a 2024 forensic genealogist finally force the case open?

    In this episode, you’ll hear the sequence of events from the last time Shannon Thorpe was seen alive to the discovery that reopened her file in 2024, and how preserved biological evidence and a consumer DNA kit led investigators back to questions the original probe left unresolved. How did a fingernail swab logged in 1993 become the key detail decades later?

    Person: Shannon Thorpe
    Date: February 9, 1993
    Location: Reservoir east parking lot area, Aldermere (path and cottonwood stand)
    Cause of death: Manual strangulation
    Evidence logged: Fingernail swab and coat-collar swab sealed February 14, 1993 and stored in biological evidence freezer

    - Shannon Thorpe was sixty-one years old and had been widowed since 1988.
    - Her purse, found twenty feet from her body, contained $42 and her car keys; the cash was untouched.
    - The medical examiner placed time of death between 5:00 and 9:00 p.m, on February 8, 1993.
    - A single right-foot brown leather flat was found upright on the lip of a concrete drainage culvert thirty feet into the trees.
    - Detective Arthur Crane identified suspect Vincent Carey within six weeks; Carey had been seen near the east lot twice the month before and had no alibi for the evening of February 8, 1993.

  • The Locked Patio, the Frozen Shoe, and the Man Who Bowled Sundays

    The Locked Patio, the Frozen Shoe, and the Man Who Bowled Sundays
    2026/08/06
    The Locked Patio, the Frozen Shoe, and the Man Who Bowled Sundays

    Cold, locked, and inexplicable: a single tan canvas shoe-size seven, laces tied, a white sock folded inside-was found frozen solid on a ground-floor patio behind apartment fourteen, with the sliding door locked from the inside; how did that shoe get there and who left it? The shoe sat in an evidence locker in Portell, Ohio for thirty years while a partial fingerprint and two biological swabs were quietly preserved, waiting for a technology that didn't exist in 1987. Who connected those preserved traces to a man who bowled on Wednesdays and attended church on alternating Sundays?

    In this episode, we lay out the facts recovered from the Sycamore Glen apartment and the decades-long investigation: the scene details, the preserved evidence, and the elusive visitor Nancy mentioned after a December party. What does the frozen shoe, the cleaned surfaces, and the later DNA profile reveal about the last hours of Nancy Olson?

    Person: Nancy Olson
    Date: January 5-9, 1987 (discovery on January 9)
    Location: Apartment 14, Sycamore Glen, Portell, Ohio
    Evidence: tan canvas right shoe (size 7), white sock, partial fingerprint, two cotton swabs
    Status: evidence preserved; case remained open for decades

    - A meter reader unhooked the patio latch on January 9, 1987 and found a tan canvas right shoe, size seven, with laces tied and a white sock folded inside, both frozen solid.
    - The sliding patio door was locked from the inside with a hook-and-eye mechanism and the six-foot wooden fence made outside placement difficult without climbing.
    - Nancy Olson lived alone in apartment fourteen, turned 24 in October 1986, worked 18 months as a design assistant at Haverfield Creative, and owned a tabby cat named Biscuit.
    - Detective Pete Kosar collected a partial fingerprint from the interior bathroom window frame and two cotton swabs (from the shirt collar and the interior front door handle); all were sealed and frozen in January 1987.
    - In 2003 a lab technician extracted a partial DNA profile from one of Kosar’s swabs, years after the evidence had been preserved.

  • The Frozen Cigarette That Named a Killer: The Freezer Shelf Mystery

    The Frozen Cigarette That Named a Killer: The Freezer Shelf Mystery

    The Frozen Cigarette That Named a Killer: The Freezer Shelf Mystery

    Cold air, a wool blanket folded with care, and a frozen cigarette butt that sat untouched for twenty-eight years - one tiny cell of DNA would eventually point to a killer through a genealogy lead. How did a cigarette frozen since 1991 travel from evidence locker to a family tree and finally answer the question no investigator could solve for decades?

    In this episode, we follow the timeline from discovery to resolution: the December 1991 death of David Ramsey, the Selden County homicide file detective Sylvia Marsh compiled, the preserved menthol cigarette recovered near the body, and the forensic genealogy work that connected the evidence to a living relative. Could one degraded cigarette butt and a genealogy database really close a case that stalled for nearly three decades?

    Person: David Ramsey
    Date: December 9, 1991
    Location: Behind Calvary Lutheran Church, Pratt Falls
    Person: Sylvia Marsh
    Evidence: Menthol cigarette butt with filter (collected ~18 inches from Ramsey's right shoulder)

    - Body discovered at 11 degrees Fahrenheit on Monday morning, nine days after Ramsey stopped answering his phone.
    - Ramsey was 48 years old at time of death and had $37 and a photograph in his wallet when found.
    - The wool blanket covering Ramsey had burgundy stripes aligned parallel to his body's long axis.
    - Medical examiner estimated death occurred 14-18 hours before discovery and recorded two blunt-force strikes to the base of the skull.
    - The menthol cigarette butt was collected in December 1991, produced a partial DNA profile by 2004, and remained in cold storage until later forensic genealogy testing.
