The Unsolved Files

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 connected to a $1 million demand sent to Johnson & Johnson, but he was never charged with the poisonings. In 2026, Idaho investigators announced a possible lead involving Mathew Francis Betkouski while emphasizing that they could not place him in Chicago during the critical period.

This episode examines what the physical evidence showed, how the public-health response unfolded, and why no public evidence has placed a specific person at the act of tampering.

On 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 reached authorities. A postcard signed “Black Dahlia Avenger” appeared in the press. Neither item has been tied to an authenticated sender.

The Los Angeles Police Department led the homicide investigation, with FBI support for identification, records checks, and interviews. Later theories named doctors, acquaintances, and other suspects, but none produced a charge or an official solution. The case remains unresolved because the surviving public record identifies Elizabeth Short, but not the person who encountered her after the Biltmore, killed her elsewhere, and left her on Norton Avenue.

In 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 separate Terre Haute homicide, updated sketches, coordinated across agencies, and pursued renewed forensic testing. Some evidence has produced leads. None has publicly identified the person responsible for the confirmed 1992 series.

This episode follows the documented timeline, the evidence that connected five crime scenes, and the crucial gap that remains: how to connect a linked weapon, a witness account, and decades of investigative work to one identifiable offender.

In 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 follows the documented expedition, the search, the forensic evidence, and the question that remains unresolved: did a snow slab strike or threaten the camp, or did another immediate event separate nine people from the shelter they needed to survive?

On 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 handwriting evidence, and unidentified male DNA have each been interpreted in sharply different ways.

One explanation is that an intruder entered or remained in the home. Another is that someone inside the house knew more about JonBenét’s death and that the kidnapping story was staged. No one has been charged with her murder. Nearly three decades later, the case remains open because the evidence still cannot establish who created the contradiction between the note upstairs and JonBenét’s body downstairs.

On December 5, 1945, five United States Navy TBM Avenger bombers left Naval Air Station Fort Lauderdale for a routine navigation and practice-bombing exercise over the Bahamas. Fourteen men were aboard. The flight reached its target, completed its bombing run, and then became lost during the return portion of the mission.

Its leader, Lieutenant Charles Carroll Taylor, reported that both compasses in his aircraft had failed. He believed the formation was over the Florida Keys. But the planned route, the islands below, and later shore-based radio bearings suggested the aircraft may instead have been east of Florida, near or north of the Bahamas. Other pilots in the formation argued that flying west would take them home. Taylor’s interpretation pointed in another direction.

For hours, Navy stations tried to guide the five aircraft through weakening radio contact, worsening weather, darkness, and dwindling fuel. The last clear messages included an instruction for the planes to close formation and prepare to ditch together. None returned.

A PBM Mariner launched to search for Flight 19 also disappeared with thirteen men aboard, probably after an airborne explosion seen from a merchant vessel. The Navy’s initial reconstruction blamed navigational confusion, but its formal finding was later amended to cause unknown. No confirmed wreckage from Flight 19 has ever been recovered. The unanswered question is not whether the flight was in trouble. It is where five aircraft, still communicating until late in the evening, finally entered the sea.

Between December 1968 and October 1969, five people were killed and two survived a series of attacks across Northern California that authorities came to associate with an unidentified offender calling himself Zodiac. David Faraday, Betty Lou Jensen, Darlene Ferrin, Cecelia Shepard, and Paul Stine were killed. Michael Mageau and Bryan Hartnell survived and gave investigators rare firsthand accounts.

The case changed after the attacker began calling police and writing to Bay Area newspapers. His letters included crime details, threats, a cross-circle symbol, cryptograms, and, after the murder of San Francisco taxi driver Paul Stine, pieces of Stine's bloodstained shirt. That clothing provided powerful proof that the writer had direct access to evidence from a confirmed murder.

Two of Zodiac's major ciphers were eventually solved. The first, Z408, was deciphered in 1969 by Donald and Bettye Harden. The second, Z340, resisted solution for fifty-one years before David Oranchak, Sam Blake, and Jarl Van Eycke decoded it in 2020. Neither message identified the writer. Two shorter ciphers remain without accepted solutions.

This episode follows the confirmed timeline, the surviving witnesses, the multi-jurisdictional investigation, the evidence surrounding the best-known suspect Arthur Leigh Allen, and the limitations of handwriting, fingerprints, and DNA drawn from decades-old correspondence. The central question remains: how did a killer who left so much material behind avoid a publicly verified identification?

In 1888, a series of murders in London’s East End became one of history’s most famous unsolved cases. Five women—Mary Ann Nichols, Annie Chapman, Elizabeth Stride, Catherine Eddowes, and Mary Jane Kelly—are traditionally grouped as the canonical victims of Jack the Ripper. But that label was created after the killings began, and the name itself came from an anonymous letter whose author was never identified.

This episode follows the documented chronology: Nichols’s final search for lodging money, the discovery of her body in Buck’s Row, Chapman’s murder in a crowded Spitalfields yard, and the letter signed “Jack the Ripper.” It reconstructs the night of the double murder, when Stride and Eddowes were found less than an hour apart, and examines the bloodstained apron fragment and disputed Goulston Street writing that led police away from Mitre Square.

It also investigates the human kidney sent to vigilance leader George Lusk, Mary Jane Kelly’s murder inside Miller’s Court, the later police claims pointing toward a suspect called Kosminski, and the modern DNA controversy surrounding an alleged Eddowes shawl.

The case remains unresolved because its most dramatic evidence repeatedly fails at the same point: it may suggest a suspect or a pattern, but it does not securely identify the person responsible.

On February 2, 2009, Christine Ross and her dog, Ruca, found a human bone protruding from the ground on Albuquerque’s West Mesa. The discovery near 118th Street Southwest led investigators to an isolated burial area containing the remains of 11 women and the unborn child of Michelle Valdez.

The women had disappeared years earlier, many during the period from 2003 through 2005. Every victim was eventually identified, but no one has been charged with their murders.

This episode examines the discovery, the missing-women pattern noticed before the graves were found, the difficult forensic recovery, the geography of the mesa, and the suspects investigators have examined. It also confronts the case’s central conflict: whether the deaths were caused by one offender, multiple offenders, or a wider series that may include women who are still missing.

As of February 2026, the City of Albuquerque and Albuquerque Police Department continued to describe the investigation as active and unsolved.

On June 10, 1912, Mary Peckham noticed that the Moore home in Villisca, Iowa, had remained unusually quiet. When Ross Moore entered the residence, he found two young overnight guests dead in a downstairs room. A search of the rest of the house revealed the full scale of the crime: eight victims, including six children.

The Moore family had attended a Presbyterian church Children’s Day program the evening before. Sometime after they returned home, an unknown attacker used an axe believed to have been associated with the Moore property to kill everyone inside.

The investigation generated local-feud theories, accusations involving businessman Frank F. Jones, a disputed traveling-offender theory involving William Mansfield, and a confession from Reverend George Jacklin Kelly. Kelly was tried twice. His first trial reportedly ended with a hung jury, and he was acquitted at the second trial.

This episode separates documented facts from disputed crime-scene claims, follows the known chronology of the investigation, and examines the central conflict that remains: did the failed case against Kelly obscure an unknown offender, or did it involve a genuine confession that could not be proven in court?

The Moore house still stands in Villisca. The victims are known. The identity of the person responsible is not.
