January 17th, 1887. Ansel Bourne, a Rhode Island preacher, goes to a bank in Providence to withdraw money. He never comes home.

His wife reports him missing.

By March, in Norristown, Pennsylvania, a quiet man calling himself A.J. Brown is running a small shop selling stationery, candy and fruit. He is orderly. He goes to church. Customers notice nothing strange. He never mentions a past.

On March 14th, Brown wakes up terrified. He doesn't know where he is. He tells his landlord his name isn't Brown. It's Ansel Bourne. He thinks it's still January.

The landlord fears his tenant has lost his mind and sends for a doctor. A telegram brings Bourne's nephew from Providence. The nephew confirms it. The shopkeeper is the missing preacher.

Bourne remembers nothing of the eight weeks. The last thing he recalls is a street corner in Providence.

Harvard psychologist William James and researcher Richard Hodgson put him under hypnosis. They could bring Brown back. Each self seemed unaware the other existed. James wrote that Bourne's "skull to-day still covers two distinct personal selves."

James called it a spontaneous hypnotic trance. Modern psychiatry calls it a probable dissociative fugue, a rare condition with no standard treatment.

For eight weeks, one man lived as someone else. The man he was had no idea.

December 4th, 1982. A man walks into Sacred Heart Catholic Church in Boise, Idaho, and dies of cyanide poisoning. He is found under a pew. Authorities say he took his own life.

He has no ID. His fingerprints match nothing, locally or with the FBI. On him: a wallet with no cards, an envelope with nineteen $100 bills, two key rings holding nearly thirty keys, and a typed note signed "Wm. L. Toomey."

The name is fake. His hair is dyed. His clothes are new.

For nearly 44 years, nobody knows who he is. He becomes the Unknown Wanderer.

Then a cold case detective reopens the file. One engraved key leads to a street in Jacksonville, Florida, and to a property owner who vanished in 1982. On September 23rd, 2026, the Ada County Sheriff's Office gives the Wanderer a name: Dr. Mathew Francis Betkouski, an organic chemist. Familial DNA from his brother and photo comparison confirm it.

Then they said the part that made headlines.

In the fall of 1982, seven people around Chicago died after taking Extra-Strength Tylenol capsules laced with cyanide. Nobody has ever been charged. The case led to a nationwide recall and tamper-resistant packaging.

Investigators say Betkouski disappeared from his home in Las Cruces, New Mexico around October 15th, 1982, after selling his car. Seven weeks later he was dead in Boise, looking like a different man. Colleagues recalled him discussing the "perfect crime" and cyanide. Another scientist recalled him saying poison could be put into over-the-counter capsules. Among his belongings at his family's Los Angeles home: a map of Chicago and a bottle of sodium cyanide.

Authorities call it a possible connection. They have not named him a suspect.

Here is what's missing. Photos place him in Chicago in December 1981, not 1982. Investigators cannot place him there when the capsules were tampered with. The Tylenol killer used potassium cyanide. What was found with his belongings was sodium. Jeremy Margolis, a former federal prosecutor on the original task force, calls it "the wrong cyanide." Forensic psychiatrist Park Dietz, who consulted on the 1982 investigation, says it makes no difference, and that Betkouski probably did it.

For decades, the best-known suspect was James Lewis, who sent Johnson & Johnson a letter demanding $1 million to stop the deaths. He was convicted of extortion, never charged with the murders, and died in 2023. His DNA did not match the bottles.

The man with no name has one now. Whether it leads to seven deaths that still have no killer is the open question.

A feature-length Unsolved Mysteries documentary on the case, Unmasking the Tylenol Killer, streams free on The Roku Channel October 9th.

May 28th, 1974. A strangled woman is found on the jetty at Alamitos Beach in Long Beach, California. She's wearing a white gold engagement ring and a pinkish-orange pantsuit. No one reports her missing.

Thirty-nine years pass. In 2013, police arrest her killer. He confesses to meeting her at a bar. He's not sure of her name, maybe "Ana," maybe "Anna." He dies in custody of cancer before trial.

Her killer has a name on a court record. She still doesn't have one.

She was the most famous face in New York, and nobody could tell you who killed her.

July 25th, 1841. Mary Rogers leaves her boarding house, tells her fiancé she's off to visit a relative for the day. She never comes home.

Mary wasn't just anyone. She worked the counter of a Broadway cigar shop, and her looks had turned her into something close to a celebrity, admired by the city's writers and literary men. One of her regular customers was a young Edgar Allan Poe.

Three days later, her body is pulled from the Hudson River near Hoboken, badly beaten, strangled.

Her fiancé, Daniel Payne, never recovers. Months later, he's found dead on the very bench overlooking where her body had washed up, having swallowed poison. Grief, guilt, nobody was ever sure which.

A year after that, the story cracks open in the strangest way possible. A woman who ran a riverside inn near where Mary died is accidentally shot by her own son. Dying, she finally confesses something she'd kept quiet for a year: Mary's death, she says, came from a botched abortion, and the mysterious man Mary was last seen with was never a stranger at all.

It was enough to reshape the whole story. It was never enough to close the case. Nobody was ever charged.

Poe decided to try solving it himself, the only way he could: in fiction. He rewrote the case entirely, moved it to Paris, renamed Mary as Marie, and invented a detective to succeed where the real police hadn't, C. Auguste Dupin. Even with every real detail of the case in front of him, Poe's own detective wouldn't commit to a name. Dupin theorizes. He never confirms.

The case still left a permanent mark, just not the one anyone expected. It helped push New York to rebuild its entire police department in 1845, and directly shaped the state's first law criminalizing abortion that same year.

Nearly two centuries later, the Beautiful Cigar Girl's death is exactly what it was the day they pulled her from the river: unsolved. Even the man credited with inventing the modern detective story couldn't crack it.

In 2009, a man calling himself Peter Bergmann checked into an Irish hotel, gave a fake Vienna address, then spent three days walking in and out of town carrying a purple plastic bag, believed by police to hold his own belongings, which he was getting rid of piece by piece. Days later, he was found dead on a beach nearby. Seventeen years on, nobody has ever learned who he really was.

[Cause Unknown @CauseUnknownX]

December 31st, 1970. Somewhere in Connecticut, a couple living under fake names are about to run out of luck. He calls himself Dirk Stahl. She calls herself Lorraine.

Neither name is real.

The man is actually Gustavous Lee Carmichael, a convicted bank robber who'd escaped from U.S. Marshals custody roughly two months earlier while being transported to a sentencing hearing. Somewhere during his time on the run, he met a woman, and together they built an entire fake life around stolen identification, a rented house in Noank, a checking account under names that belonged to no one.

She wasn't fully at ease inside that story. While staying at a house in Ledyard connected to one of Carmichael's criminal associates, she confided to a woman named Joanne Rainello that she was afraid of the life she was living. She never said enough to explain what actually happened to her that New Year's Eve.

Both of them were shot dead. Their bodies weren't found until May 30th, 1974, more than three years later, deep in the woods outside Ledyard, after an informant finally tipped police off to where the murders had actually happened.

Investigators eventually identified Carmichael, whose criminal record made him far easier to trace than the woman beside him. She'd been living under a fake name when she died, so even her own alias led nowhere. She became a Jane Doe with only a sketch for a face, unidentified twice over, once by the world that never knew her real name while she was alive under a fake one, and once by investigators who couldn't connect a body to any name at all.

It took fifty years and genetic genealogy to finally close that gap. In February 2024, DNA led investigators back to Louisville, Kentucky, and to the name she'd left behind before she ever became Lorraine Stahl: Linda Sue Childers, 24 years old when she died.

She spent her final months erasing herself on purpose. It still took half a century for anyone to put her back together.

July 13th, 2016. In Crestone, Colorado, a town of just 143 people known as a magnet for spiritual seekers, 29-year-old Kristal Reisinger is last confirmed seen at her apartment. She'd moved there only a month earlier, chasing something she'd been looking for through Denver and Gunnison before it: peace, sobriety, a fresh start, though it meant leaving her young daughter behind in the meantime.

She never got the chance to send for her. Inside her apartment, investigators later found her purse, phone, and laptop, all left behind, the kind of details that usually mean someone didn't leave on their own.

Some locals have said they saw her at a community drum circle days later, though it's never been officially confirmed the way her July 13 sighting was. Police reportedly believe someone who was at that gathering knows more than they've said.

Search teams, helicopters, and cadaver dogs turned up nothing in the weeks that followed. By 2018, investigators believed they were looking at foul play, not a voluntary disappearance, and the case was handed to Colorado's state bureau of investigation.

In 2022, someone found burned bones near a Crestone campground, and for a moment it looked like the case might finally close. It didn't. The remains turned out to be a stranger's scattered cremains, unconnected to Kristal entirely.

Then, in August 2025, nearly a decade after she vanished, investigators returned to Crestone with four cadaver dogs and searched a specific location they now believe is connected to her case. They haven't said what, if anything, they found. What they have said is that the investigation is still active.

Nine years later, they're still waiting for someone to come forward.

If you know anything, Colorado's tip line is still open, and anonymous: [phone].

This is why the Still Missing file exists. Some of these are decades cold. This one might still be warm.

In 1920s Los Angeles, a cult built a stone oven specifically to "treat" sick members. A paralyzed woman who couldn't speak for herself was placed inside it. She was dead within two days. Nobody was ever charged.

[Cause Unknown @CauseUnknownX]

Los Angeles, 1922. A woman named May Otis Blackburn tells her small circle of followers that the archangels Gabriel and Michael have appeared to her and her daughter, naming them the "two witnesses" from the Book of Revelation. Together, she says, they've been chosen to write a book containing the secrets of heaven, earth, life, and death itself.

The book, once finished, would reveal hidden mineral riches waiting to be claimed near Bakersfield, and detail an apocalyptic new world ruled by eleven queens, Blackburn and her daughter among them.

Followers gave everything to keep the writing going. One member, an oil man named Clifford Dabney, handed over tens of thousands of dollars over several years, waiting for the book he'd funded to finally appear.

It never did.

While Dabney waited, stranger things were happening inside the cult's circle. A foster child living with cult members, Willa Rhoads, died. Instead of burying her, the family kept her body, first packed in ice, later wrapped in spices and salt and hidden beneath the floor of their own house, surrounded by the bodies of seven dead dogs. They told investigators they believed the cult's powers could bring her back.

Another follower, paralyzed and unable to speak for herself, was placed inside a stone oven the cult had built specifically for "treatments." She died two days later.

Ruth's own husband disappeared around this time too, reportedly last seen after striking his wife. He was never found.

When Dabney finally went to police, furious that his money had bought nothing, it wasn't murder charges that followed. Despite two deaths connected directly to the group's rituals, nobody was ever charged in either one. Blackburn was tried only for grand theft, over the money, and even that conviction didn't survive an appeal to the California Supreme Court.

She spent the rest of her life free, publishing a book of her own beliefs in 1936, and died in Los Angeles in 1951, having never faced consequences for anything that happened inside the world she built.

In 1943, four boys poaching in an English wood found a human skull inside a hollow tree. The full skeleton was still there, missing one hand, found scattered nearby. A year later, graffiti started appearing on walls miles away asking one question: who put Bella in the wych elm. Eighty years on, nobody has ever answered it.

September 1st, 1934. A badly burned body is pulled from a culvert outside Albury, Australia. She's been shot in the neck, beaten, her head wrapped in a towel. She's wearing yellow silk pyjamas with a Chinese dragon pattern, the kind of luxurious clothing nobody expected to find on a roadside body in the middle of the Depression.

Nobody claims her. Nobody can identify her. So Australian police make a decision that would be unthinkable today: they preserve her body in a zinc-lined bath of formalin and put her on public display at Sydney University, hoping someone, anyone, might recognize a face nobody else could name.

She stays there for almost a decade. Hundreds, maybe thousands, file past to look.

Even at the time, the identification wasn't clean. A doctor named Thomas Benbow spent years insisting the body actually belonged to a different missing woman, and her father funded an entire legal case trying to prove it. He lost.

In 1944, dental records instead connected her to Linda Agostini, a British-born woman who'd left London for a new life in Australia. Her husband, Antonio Agostini, was arrested and convicted, not of murder, but manslaughter. He served under four years and was deported to Italy.

Case closed, mystery solved. That was the official story for decades.

But the doubt never fully went away. Later examination of the case has concluded the body buried under Linda Agostini's name may genuinely be a different woman, meaning the real Linda Agostini is still unaccounted for, and the woman Australia put on display for a decade, stared at by thousands of strangers hoping to name her, may never actually have been identified at all.

July 31st, 2002. A wellness check leads police into a small apartment in Eastlake, Ohio. Inside, a man who called himself Joseph Newton Chandler III is dead by his own hand, eight days earlier. He'd shut off the air conditioning first, sealed the windows, then shot himself. The heat had done its own kind of damage by the time anyone found him, decomposition had taken his fingerprints along with everything else.

He had no will. No family ever came looking. When investigators went searching for next of kin, what they found instead unraveled the entire life he'd built.

The real Joseph Newton Chandler III had died on Christmas Day, 1945, in a car crash in Sherman, Texas. He was eight years old.

The man in the Eastlake apartment had stolen a dead child's name in 1978, walked into a Social Security office in Rapid City, South Dakota, and simply became him. He moved to Ohio that same year, took a job at a chemical company, and lived as Joseph Chandler for the next twenty-four years. Coworkers knew him. Neighbors knew him. Nobody knew any of it was borrowed from a boy who'd been dead for over three decades.

It took investigators sixteen more years, and genetic genealogy, to answer who he actually was. In 2018, DNA traced him back to Robert Ivan Nichols, a Navy veteran who'd served aboard the USS Aaron Ward when it was bombed by Japanese forces in 1945, earning a Purple Heart for it.

In 1964, Nichols filed for divorce, left his wife and three sons, and moved to Michigan, then California the following year. His son's last contact with him was a letter, postmarked Napa, in 1965.

Then silence, for thirteen years, until a dead eight-year-old's name resurfaces in South Dakota in 1978, attached to a grown man starting an entirely new life.

What happened in those thirteen years has never been explained. Neither has why he chose that specific name, or what he was running from badly enough to erase himself completely rather than just disappear. One detail investigators haven't ruled out: Nichols was living in California during the years the Zodiac Killer was active there. Nobody has confirmed a connection. Nobody has ruled it out either.

He left behind $82,000 in an Ohio bank account and a name that wasn't his. He has a name back now. The thirteen years he never explained still don't.

January 30th, 1989. Ilene Misheloff is thirteen years old, an eighth grader at Wells Middle School in Dublin, California, the kind of kid who'd been ice skating since she was four and already knew she wanted to be a pediatrician someday.

That afternoon, around three o'clock, she starts the walk home alone, the same route she always takes, down Amador Valley Boulevard toward Village Parkway.
She never arrives.

Her key fob is found later near the entrance to John Mape Park, right along the path she always walked. Nothing else. No struggle reported by anyone nearby, no witness who saw what happened next.

For more than thirty years, on the anniversary of her disappearance, the Dublin community held a candlelight walk along that same route, parents, neighbors, people who'd never even met Ilene, keeping her name in front of the town so the case wouldn't quietly fade the way so many do. Her mother, Maddi, helped lead that vigil every single year.

The tradition ended in 2020, when Maddi died of cancer, a mother who spent three decades not knowing what happened to her daughter, and never got the answer before she passed.

The case didn't close with her. Later that same year, Dublin police reopened the file again after a man was charged in a strikingly similar case nearby, a young girl who vanished from a Bay Area street around the same era. Investigators are still actively working to determine whether the two might be connected.

Ilene would be fifty years old this year. A reward of roughly $95,000 still stands for information leading to an arrest and conviction.

If you know anything, even something that's felt too small to mention for thirty-six years, Dublin Police still wants to hear it: [phone]. Or the FBI's San Francisco field office: [phone].

This is why the Still Missing file exists. Some of these aren't waiting on DNA. They're waiting on someone remembering.

July 26th, 1974. A woman's body is found in the dunes near Provincetown, Massachusetts. She's been struck in the skull, her head nearly severed. Her hands are gone entirely, removed, investigators believe, specifically so she could never be fingerprinted.

No missing persons report matches her. No dental records lead anywhere. She becomes known only as the Lady of the Dunes, and for the next forty-eight years, she holds a record nobody wants: the oldest unidentified homicide victim in Massachusetts history.

In October 2022, FBI investigative genealogists finally give her a name. Ruth Marie Terry, 37, originally from Tennessee. She'd used other names too in her life, Teri Marie Vizina, Teri Shannon, aliases nobody had connected to her until now.

Once investigators have her identity, everything else moves fast. Records show Terry married a man named Guy Rockwell Muldavin sometime in 1973 or 1974. He had aliases of his own, Raoul Guy Rockwell, Guy Muldavin Rockwell. The couple honeymooned that summer, stopping in Tennessee so Terry could see her family.

Then Muldavin came back alone, driving what looked like her car. He told people they'd fought on the honeymoon and he hadn't heard from her since. When Terry's brother tried to help track her down, Muldavin gave him the same story.

It wasn't the first time people close to Muldavin had died under questionable circumstances. Decades earlier, in Seattle in 1960, his previous wife and her daughter had died in a way that made him a suspect. He was never charged.

Muldavin died in 2002, more than twenty years before anyone would connect his name to the woman found in the dunes.

In August 2023, nearly fifty years after Ruth Marie Terry died, prosecutors officially closed her case. Their conclusion: her husband was responsible. Her case is answered now, in every way except the one that would have mattered most, a trial that never came, because the only man who could have stood in it had been dead for years.

Croydon, England, 1928. A retired colonial civil servant named Edmund Duff comes home from a fishing holiday, has a drink, and is violently ill within hours. He's dead by morning. His doctor can't explain it and even raises the idea of poisoning himself, but nothing comes of it.

Ten months later, in February 1929, Duff's sister-in-law, Vera Sidney, falls ill after lunch with the same kind of cramping and vomiting. She dies two days later. Her doctor blames gastric influenza.

Three weeks after that, Vera's own mother, Violet Sidney, falls ill after lunch too. She complains that her prescribed tonic tastes "gritty" and burns her throat. She's dead within hours.

Three members of one family, dead within eleven months of each other, in the same house.

It's the family itself, not investigators, who finally push for an inquest after Violet's death. Once they do, all three bodies are exhumed. All three had lethal arsenic in their systems, later traced to a tin of weedkiller from the garden shed, believed to have been mixed into Edmund's beer, Vera's soup, and Violet's tonic.

Scotland Yard investigated for months. There was an obvious circle of suspects and an obvious motive, each death left the estate to fewer people. What they never found was enough evidence to charge anyone.

Agatha Christie herself was invited to study the case that year and, by her own account, called it a genuine dead end, the kind of mystery where every path leads to a blind alley.

Nearly a century later, it still hasn't resolved. Three deaths, one house, one obvious circle of suspects. The victims all had names. Their killer never did.

November 29th, 1970. A hiking trip should have ended with nothing more than tired feet. Instead, two young sisters and their father stumble across a body in the Isdalen Valley outside Bergen, Norway, a valley locals had already been calling "Death Valley" for generations, long before this.

The woman is burned almost beyond recognition, her arms raised in a way forensic examiners would later explain as the body's natural reaction to extreme heat, not a final gesture. Scattered around her: an empty liquor bottle, sleeping pills, a fur hat soaked in petrol.

No purse. No papers. Nothing with her name on it. Every label, on every item, had been deliberately removed.

Three days later, two suitcases turn up at the Bergen railway station. Inside: wigs, foreign currency from half a dozen countries, a pair of glasses with her fingerprints still on the lenses, and eight separate passports, eight different names, none of them real.

Hotel records only deepen it. In the weeks before her death, she'd checked into hotels across Norway under a rotating cast of aliases, always paying cash, always requesting a different room, wiping down glasses and cutlery after every meal like she'd been trained to leave nothing behind.

Even her own fingerprints had been deliberately filed down.

Police closed it as a probable suicide. It's never stopped generating theories since, most persistently, that she was a Cold War intelligence operative, caught somewhere she shouldn't have been.

In 2016, Norwegian investigators reopened the file. Modern isotope analysis on her remains points toward southeastern Germany, near Nuremberg, as a likely origin.

That's still the closest anyone has come. Not a name. Just a direction to look.

May 31st, 1995. A young woman checks into Room 2805 of the Oslo Plaza Hotel, one of Norway's most luxurious. She gives her name as Jennifer Fairgate. She lists an address in Verlaine, Belgium.

That address doesn't exist. Neither does the phone number she provides. No credit card is ever put down for the room.

Three days later, a security guard is sent up over the missing payment card. As he knocks on her door, a gunshot goes off inside. Jennifer is found dead on the bed, a pistol in her hand, a single wound to her forehead.

It should have been an open-and-shut case. It wasn't. The gun was a counterfeit copy, and its registration number had been deliberately removed with acid. Every label had been cut from her clothes. No toiletries, no hairbrush, nothing in the room that could carry a trace of who she actually was.

Investigators ruled it a suicide. A Norwegian intelligence officer who later reviewed the case disagreed, pointing to the position of the gun and the missing gunshot residue as signs of something else entirely, an execution staged to look like a woman who simply wanted to disappear.

In 2016, her body was exhumed. Investigators pulled a full DNA profile, hoping it would finally answer who she was. It matched no one, in any database, anywhere.

Thirty years later, "Jennifer Fairgate" isn't even her real name. It's just the only one she ever gave anyone. Whoever she actually was is still, officially, cause unknown.
