Episode's summary
In late September 1982, a series of medical emergencies across the Chicago area became one of the most consequential unsolved poisoning investigations in American history. Seven people, including 12-year-old Mary Kellerman and three members of the Janus family, died after taking Extra-Strength Tylenol capsules contaminated with potassium cyanide. The deaths first appeared unrelated. They occurred in separate homes, suburbs, workplaces, and hospitals. Only after physicians, toxicologists, police, and public-health officials compared the cases did they identify a shared exposure: Tylenol capsules from ordinary retail bottles. The discovery prompted emergency warnings, local product removals, a nationwide Tylenol recall, and an investigation involving local police, medical examiners, Illinois authorities, federal agencies, and Johnson & Johnson. Investigators traced bottles, receipts, retail locations, product lots, extortion letters, and later forensic evidence. James Lewis was convicted of attempted extortion…

The Chicago Tylenol Murders: Who Put Cyanide Into Medicine Bottles?

The Black Dahlia: Who Killed Elizabeth Short and Left Her in Los Angeles?
ListenedOn January 15, 1947, Elizabeth Ann Short was found murdered in a vacant lot on South Norton Avenue in Los Angeles. She was twenty-two years old. Her body had been mutilated and placed there after death elsewhere, according to the absence of blood at the discovery site described by the FBI. Within hours, investigators had achieved one remarkable breakthrough. Blurred fingerprints were transmitted from Los Angeles through a newspaper Soundphoto system to the FBI, which identified the victim as Elizabeth Short in fifty-six minutes. Yet that success exposed the central problem: police knew who she was, but could not establish who had killed her, where the killing occurred, or how her body reached Norton Avenue. The documented trail narrows sharply after January 9, when traveling salesman Robert “Red” Manley later said he left Short at the Biltmore Hotel in downtown Los Angeles. Her movements during the following days remain unverified in the available record. An envelope containing her personal papers later…
The I-70 Killer: Who Was the Stranger Killing Store Clerks Across the Midwest?
ListenedIn the spring of 1992, six people were killed while working in small retail businesses across Indiana, Kansas, and Missouri. The cases began with Robin Fuldauer, a twenty-six-year-old Payless ShoeSource manager in Indianapolis. Three days later, Patricia Magers and Patricia Smith were killed inside a Wichita bridal shop. Michael “Mick” McCown was killed at a Terre Haute ceramics store, followed by Nancy Kitzmiller in St. Charles and Sarah Blessing in Raytown. Police eventually linked the six killings through firearm and ammunition evidence, transforming separate local homicides into one of the Midwest’s most enduring unsolved murder series. A customer who entered the Wichita bridal shop encountered an armed man and later supplied the description used for suspect sketches. Yet a description, like a ballistics connection, could point investigators toward a person without establishing who that person was. Over the decades, investigators have considered possible later crimes, reviewed surveillance from a…
Dyatlov Pass: What Made Nine Hikers Flee Their Tent Into the Frozen Night?
ListenedIn February 1959, searchers found an empty tent on the eastern slope of Kholat Syakhl in the northern Ural Mountains. Nine hikers led by Igor Dyatlov had disappeared after establishing camp there. Their boots, clothing, and equipment remained behind, while tracks described by searcher Boris Slobtsov led downhill toward the forest. The search uncovered bodies near a cedar tree, on the slope between the forest and tent, and later in a snow-covered ravine. Forensic records documented cold exposure across the group and major traumatic injuries in three cases. A later examination found that specified cuts in the tent fabric had been made from inside. The 1959 investigation closed without identifying what caused the departure. Russian prosecutors later favored an avalanche explanation, while a 2021 study demonstrated that a delayed, relatively small slab release was physically possible under modeled conditions. But no witness, recording, or unique physical trace establishes what happened at the tent. This episode…
JonBenét Ramsey: What Happened Inside the Ramsey House That Night?
ListenedOn December 26, 1996, John Ramsey and family friend Fleet White went downstairs to search the Ramsey home in Boulder, Colorado. For hours, the household had been treated as the scene of a kidnapping. Patsy Ramsey had found a three-page handwritten ransom note demanding $118,000 and called 911 at 5:52 that morning. Police arrived, friends entered the house, and an earlier basement search failed to locate six-year-old JonBenét Ramsey. At about 1:00 p.m., John Ramsey turned on the light in a small basement room and found his daughter’s body. The discovery changed the case from a reported kidnapping to a homicide, but it also came after the house had been occupied, searched incompletely, and disturbed by police, friends, and family. The autopsy established that JonBenét died from strangulation associated with severe head trauma. It did not identify her killer, establish the exact sequence of injuries, or determine a precise time of death. The ransom note, the basement window, household materials, disputed…
