Five murders. Two survivors. Four ciphers, two of which are still uncracked. More than fifty years of suspects, theories, documentaries, and confessions that turned out to be nothing. The Zodiac is the most famous unsolved case in American criminal history, and what makes it interesting is not just that the killer was never caught but that he wanted, more than anything, to be remembered. He succeeded. This is the full account.
Contents
Part One: Lake Herman Road
The killings began, as best the historical record can establish them, on the night of 20 December 1968. David Faraday, seventeen, and Betty Lou Jensen, sixteen, were on their first date together. They were students at Hogan High School in Vallejo, California, a working-class city of about 70,000 on the northern shore of San Pablo Bay. They had told their parents they were going to a Christmas concert. Instead they drove to a lover’s lane on Lake Herman Road, a quiet stretch outside Benicia, and parked.
At approximately 11:10 p.m. another car pulled up alongside them. A man got out. He fired a single shot through the back window of the Rambler station wagon Faraday had borrowed from his mother. Faraday and Jensen scrambled to get out of the car. Jensen made it perhaps thirty feet before she was shot five times in the back. Faraday was shot once behind the left ear at point-blank range as he tried to climb out of the passenger side. Both died at the scene.
There was no obvious motive. Nothing had been taken. The teenagers had not been sexually assaulted. The local police had a possible witness — a woman who had driven past the parking spot shortly before the shooting and seen a parked car — but no suspects, no fingerprints, and no immediate connection to anything else. The murders went unsolved through the spring and summer of 1969. They were, by the conventions of the day, almost certainly going to become a cold case of the kind that small Solano County police departments accumulated in those years.
What changed everything came seven months later, in the middle of the next summer.
Part Two: Blue Rock Springs
Just before midnight on 4 July 1969, Darlene Ferrin, twenty-two, and Michael Mageau, nineteen, drove to a parking area at Blue Rock Springs Park, four miles from the Lake Herman Road site. They had been seeing each other casually for several weeks. Ferrin was married, in the middle of a separation, working as a waitress. Mageau was a tall, slim young man who had been her friend longer than her boyfriend.
They had been parked perhaps ten minutes when a second car pulled in behind them, paused, and drove away. A few minutes later it returned. A man got out, walked to the driver’s side window of Ferrin’s Corvair, and shone a powerful flashlight directly into the car. Without a word, he began firing a 9mm pistol through the open window.
Ferrin was hit nine times. She died on the way to hospital. Mageau, struck four times in the face, neck, and chest, survived. He played dead, listened to his attacker walk back to his own car, and gave investigators the first detailed physical description of the man who would shortly become known as the Zodiac. He was a stocky white man, in his late twenties or early thirties, perhaps 195 to 200 pounds, with short curly brown hair. He was, Mageau remembered, calm.
At 12:40 a.m., a man called the Vallejo Police Department from a public phone booth outside a gas station and reported the shooting. He gave the location. He claimed responsibility for it. Then, in a flat voice, he claimed responsibility for the murders of Faraday and Jensen seven months earlier. He hung up. The phone booth, when officers reached it minutes later, was empty. The handset was hanging from its cord.
Vallejo had no name for whoever was doing this. But they now had two attacks they could link to each other, a survivor’s description, ballistic evidence connecting the bullets, and a killer who, for whatever reason, wanted them to know what he had done.
Part Three: The Letters
On 1 August 1969, the killer mailed three nearly identical letters to three Bay Area newspapers — the San Francisco Chronicle, the San Francisco Examiner, and the Vallejo Times-Herald. Each contained details of the killings that only the perpetrator could have known. Each demanded that the paper print the enclosed material on the front page or he would, in his words, “go on a kill rampage” over the weekend. And each contained one third of a 408-character cipher, which together formed a single message he claimed would reveal his identity.
The letters were signed with a symbol that would become iconic: a circle with a cross through it, like a crosshair or a celestial sighting marker. He did not yet sign himself Zodiac. That name appeared for the first time in his next letter, mailed on 7 August 1969 and addressed to the Examiner, which opened with the line: Dear Editor This is the Zodiac speaking.
The 408-character cipher was solved within a week of its publication, by a high school history teacher named Donald Harden and his wife Bettye, who worked it out in their kitchen in Salinas. The decoded message was rambling, riddled with misspellings, and unmistakably the voice of someone who wanted to be feared:
I like killing people because it is so much fun. It is more fun than killing wild game in the forrest because man is the most dangeroue anamal of all. To kill something gives me the most thrilling experence…
The message did not, as the killer had promised, reveal his identity. It revealed only that the killer was prepared to put his thinking on the page and that, despite his deliberate provocation, he was almost certainly not as clever as he wanted his audience to believe.
Over the following months and years, the Zodiac would write at least twenty letters to Bay Area newspapers. Some were genuine, confirmed by details only the killer could have known. Some were almost certainly hoaxes from copycats and obsessives. The genuine letters showed someone who had developed, over the autumn of 1969, an intense and detailed understanding of the press attention his crimes were generating — and who had begun to shape his behaviour to maximise it.
Part Four: Lake Berryessa
On the afternoon of 27 September 1969, Bryan Hartnell, twenty, and Cecelia Shepard, twenty-two, drove to a small island promontory in the southwestern shore of Lake Berryessa, in Napa County. They were students at Pacific Union College. They were also, by most accounts, in love — Shepard had recently been seeing someone else, but the relationship with Hartnell was the serious one.
They had spread a blanket on the grass near a small grove of trees. They were eating a picnic when Hartnell noticed a man approaching across the open ground from the trees behind them. The man had been watching them, he later realised, from cover. As he came closer they could see that he was wearing a strange improvised costume: a black executioner-style hood with the now-familiar circle-and-cross symbol stitched onto the chest, sunglasses fitted into the eye holes, and a heavy black bib that came down to his waist. He was carrying a pistol and a sheathed knife.
What happened over the next hour or so is one of the most chilling sequences in any American criminal case, partly because Hartnell survived and was able to describe it in detail. The attacker told them he was an escaped convict from a Montana prison who needed their car and money. He had Cecelia tie Bryan’s hands with pre-cut lengths of clothesline. Then he tied Cecelia. Then, without altering his calm tone, he drew the knife and began stabbing them — Hartnell six times in the back, Shepard at least ten times in front and back. He left them on the ground and walked back to his car.
Before he left the site, he walked to Hartnell’s Karmann Ghia and wrote on the door in black felt-tip pen. The marks consisted of the Zodiac symbol and three dates: 12-20-68, 7-4-69, and Sept 27-69-6:30 by knife. He was leaving his name on a victim’s car. He was creating, in real time, the documentary record he wanted history to have.
Hartnell, despite his injuries, dragged himself with Shepard up the slope to the road, where a man named Ronald Fong found them and called for help. Hartnell survived. Cecelia Shepard, conscious and lucid for several hours after the attack, was able to give responding officers her own description of the attacker before she died in hospital two days later.
At approximately 7:40 that evening, a man called the Napa Police Department from a public payphone in Napa and reported the attack. The handset, again, was hanging from its cord when officers arrived. A palm print was lifted from the receiver. It has never been matched to any known suspect.
Part Five: Paul Stine
The final confirmed Zodiac killing took place fifteen days later, and broke every pattern of the previous attacks.
Paul Stine, twenty-nine, was a Yellow Cab driver and a PhD student in English at San Francisco State College. On the night of 11 October 1969, he picked up a male passenger in the Theater District of downtown San Francisco. The passenger asked to be driven to the corner of Washington and Maple Streets in the wealthy Presidio Heights neighbourhood. Stine drove him there. Shortly after they arrived, the passenger drew a 9mm pistol — the same calibre as the Blue Rock Springs attack — and shot Stine once in the head. He then took Stine’s wallet, the keys to the taxi, and a piece of Stine’s bloodied shirt as a trophy.
The killing was witnessed, almost in its entirety, by three teenagers in a house on the opposite corner. They saw the killer get into the front of the cab, drag Stine’s body across to the passenger side, and methodically wipe down the interior with a cloth. They called the police while they watched. The teenagers’ description of the attacker was clear and consistent: a stocky white man with reddish-brown hair, wearing dark trousers and dark-rimmed glasses.
San Francisco Police dispatched the call to officers in the area. Two patrolmen, Donald Fouke and Eric Zelms, were within blocks of the scene and responded. As they drove towards the address, they passed a man on foot walking in the opposite direction — a stocky white man, fitting the description, walking calmly. They did not stop him. The reason they did not stop him is one of the central tragedies of the case: the initial police dispatch had described the suspect as Black, an error in transmission that was corrected only after the officers had already passed by. Fouke would later confirm in interviews that he could have stopped the man easily. He did not. The man walked on into the Presidio woods and disappeared.
Two days later, the Zodiac mailed a letter to the San Francisco Chronicle with a piece of Paul Stine’s blood-stained shirt enclosed as proof. The letter taunted the San Francisco Police for letting him walk past their patrol car. It threatened to “wipe out a school bus” with a sniper rifle. It signalled, for anyone who had been hoping the killings might be over, that the man behind them had no intention of stopping.
And then he did stop. Or at least, he stopped killing in ways that could be definitively connected to him. The letters continued for years. The murders, by most serious analysts’ reckoning, did not.
Part Six: The Letters After the Killings
Between October 1969 and approximately 1974, the Zodiac sent at least fifteen further communications to the Bay Area press and to law enforcement. The letters became progressively stranger and more disjointed. Some contained ciphers, including a 340-character cipher mailed to the Chronicle on 8 November 1969 — the Z-340, which would remain unbroken for more than half a century. Others contained taunts, threats, and what appeared to be running counts of his “score” against the police. By 1971 he was claiming seventeen victims. By 1974 he was claiming thirty-seven. Investigators have never been able to attribute more than the five confirmed killings to him, and most informed analysts believe the higher figures were probably inflation.
What the letters did do, more than anything, was establish a kind of literary persona that the killer himself seemed to be drafting in real time. He wrote about “slaves for the afterlife” — claiming that those he killed would be forced to serve him in some next world he believed in. He used a recurring set of misspellings (Christmass, paradice, experence) that became distinctive enough to authenticate later letters. He sometimes addressed the Bay Area public collectively, demanding that they wear “zodiac” buttons or face further killings. He alternately threatened mass attacks on schoolchildren and complained about the quality of his press coverage.
By the mid-1970s, the volume of communications had dropped to almost nothing. The last letter generally accepted as genuine was the so-called Exorcist letter of 29 January 1974, in which the Zodiac complained about the film The Exorcist, which he called “the best saterical comidy that I have ever seen.” A handful of letters from 1978 are disputed; most cipher and Zodiac scholars now believe they were hoaxes by a Vallejo police officer trying to revive the investigation.
Then silence.
Part Seven: The 340 Cipher
Of the four ciphers the Zodiac sent, only one was solved during his apparent active period: the Z-408 of August 1969. The Z-13, a thirteen-character cipher he claimed contained his name, has never been broken with confidence; many cryptographers believe it is simply too short to admit a unique solution. The Z-32, sent in June 1970 in a letter claiming to give the location of a buried bomb, was probably gibberish.
The Z-340 was the cipher that most haunted the case. It used a similar substitution alphabet to the Z-408, but with significant additional complexity. For more than fifty years, every effort to break it — by professional codebreakers at the NSA, by hobbyist cryptographers, by software developers — failed.
In December 2020, a team of three amateurs — David Oranchak, a software developer from Virginia; Sam Blake, an Australian mathematician; and Jarl Van Eycke, a Belgian software engineer — announced that they had broken it. The FBI confirmed their solution. The message read, in part:
I hope you are having lots of fun in trying to catch me. That wasn’t me on the TV show, which brings up a point about me. I am not afraid of the gas chamber, because it will send me to paradice all the sooner, because I now have enough slaves to work for me.
The reference to “the TV show” was a confirmation of a previous suspicion — that the Zodiac had not been the caller who phoned into the Jim Dunbar morning show on KGO-TV in October 1969 to speak with the celebrity attorney Melvin Belli, despite popular speculation at the time that he might have been.
What the Z-340 did not reveal was his name. The cipher contained, by the assessment of the team that solved it, no identifying information at all. The killer who had spent a year telling the world he wanted to be known had, when given a sustained opportunity to identify himself, chosen instead to brag.
Part Eight: The Suspects
The Zodiac case has accumulated, over more than five decades, an enormous catalogue of suspects. The vast majority have been ruled out on the basis of alibis, fingerprints, handwriting analysis, or basic plausibility. A smaller number have remained subjects of sustained speculation. One name, more than any other, has dominated.
Arthur Leigh Allen was a Vallejo schoolteacher, navy veteran, and convicted child molester who was first interviewed by police in October 1969 — within days of the Paul Stine murder — after acquaintances told investigators he had spoken about wanting to kill couples in lovers’ lanes, had owned firearms similar to the murder weapons, and had been near Lake Berryessa on the day of the Hartnell-Shepard attack. He owned a Zodiac-brand wristwatch. The brand’s logo was a circle with a crosshair through it.
For more than two decades, Allen remained the case’s central figure of interest. The San Francisco Police Department, the Vallejo Police Department, and the Solano County Sheriff’s Office all considered him their leading suspect at various times. In 1991 he was the subject of a four-hour videotaped interrogation by SFPD detectives George Bawart and Conrad Erickson, who came away convinced he was the killer but unable to assemble enough physical evidence to charge him. Allen died of natural causes in August 1992, in the Vallejo house where he had lived with his mother. He never confessed.
The case against Allen is circumstantial but substantial. The case against the case against Allen is also substantial. DNA testing of saliva recovered from envelope flaps on Zodiac letters, conducted in 2002 and again in subsequent years, has not matched Allen’s profile. Bryan Hartnell, the survivor of the Lake Berryessa attack, was shown Allen’s photograph in 1991 and said he was not the man who had attacked him at the lake. Handwriting analysts have produced mixed conclusions, some seeing Allen’s hand in the Zodiac letters and others seeing nothing definitive.
The 2024 Netflix docuseries This Is the Zodiac Speaking revived the Allen case by giving extended interview time to the Seawater family, who had been close to Allen in the 1960s and 1970s — David Seawater was one of his elementary school students — and who claim Allen made statements to them later in life that amounted to a confession. The series has been controversial. Some viewers found it compelling. Other Zodiac researchers have pointed out that the Seawaters’ detailed memories have surfaced only decades after the events they describe, and that the show does not engage seriously with the DNA evidence that ruled Allen out.
In October 2021, a separate group of investigators calling themselves the Case Breakers announced that they had identified the Zodiac as Gary Francis Poste, an Air Force veteran and house painter who died in 2018. Their evidence included claimed scars on Poste’s forehead that they argued matched a witness sketch of the Lake Berryessa attacker and what they described as anagram-style references to Poste’s name hidden in Zodiac letters. The FBI and the San Francisco Police Department both publicly rejected the identification. Most serious researchers have done the same.
Other suspects who have attracted sustained attention over the years include Ross Sullivan, a library worker with a documented mental illness who lived in Santa Rosa during the murder years; Lawrence Kane, a Nevada-based suspect with a violent criminal record; and Earl Van Best Jr, named in a 2014 book by Gary L. Stewart who believed Van Best to be his biological father. None has been confirmed by any law enforcement agency.
The case is, as of 2026, still officially open with the FBI and with at least three California law enforcement jurisdictions.
Part Nine: Why the Case Endures
There are perhaps a dozen American serial killer cases of greater body count than the Zodiac’s. Several of them remain less famous. What is it about this case, in particular, that has sustained a half-century of obsession?
Part of the answer is the ciphers. The Zodiac was the first American serial killer to systematically incorporate cryptographic puzzles into his communications with the press. He gave generations of amateur sleuths a tangible thing to work on — a code to crack, a clue to decipher — that most cases simply do not offer. The 2020 breaking of the Z-340 demonstrated that this work could, in fact, produce real results, even after fifty years.
Part of it is the geography. The Zodiac operated in and around San Francisco, a city that occupies an outsized place in American cultural imagination, during the years immediately following the Summer of Love. The juxtaposition of a hooded killer stalking lovers’ lanes against the backdrop of a city associated with peace, music, and youthful idealism produced a kind of cognitive dissonance that helped fix the case in collective memory.
Part of it is the cultural amplification. Robert Graysmith, a former San Francisco Chronicle cartoonist who covered the case in real time, wrote two enormously successful books about it: Zodiac (1986) and Zodiac Unmasked (2002). Graysmith’s books made the case famous to a generation of readers and named Arthur Leigh Allen as the killer in terms more confident than the evidence supported. David Fincher’s 2007 film Zodiac, adapted from Graysmith’s work, did the same for a film audience. The case has, in this sense, been retold so many times that the retellings have themselves become part of the story.
And part of it, the largest part probably, is the simple fact of not knowing. Almost every other famous American serial killer case has an ending — a name, a trial, a sentence, a death in prison. The Zodiac case does not. The killer remains, in 2026, formally unidentified. The man who walked past Officers Fouke and Zelms in Presidio Heights on the night of 11 October 1969 walked on into a kind of permanent inconclusiveness, and the people who have followed the case since have been unable to stop looking back at that corner.
Part Ten: The Names That Matter
The Zodiac wanted to be remembered. He achieved that, more completely than perhaps any other figure in American criminal history. The case has been retold so many times that his methods, his costume, his ciphers, his letters, his symbol have all entered the cultural vocabulary in a way the killer himself would presumably have considered an artistic triumph.
The names that should be remembered, but mostly are not, are those of the people he killed and the people who survived him. David Faraday was seventeen and a Boy Scout. He had been planning to study engineering. Betty Lou Jensen was sixteen and a talented artist. She had been excited about the dance she thought she was going to that night. Darlene Ferrin was twenty-two, the mother of an infant daughter, a woman whose family later said her warmth and generosity towards strangers had probably been part of what drew her killer’s attention. Cecelia Shepard was twenty-two and weeks away from finishing her degree. She had been studying music. Paul Stine was twenty-nine and on the cusp of completing his PhD; he had been driving a cab to put himself through graduate school.
The two survivors built the rest of their lives in the long shadow of what was done to them. Michael Mageau survived four gunshot wounds in his face, neck, and chest at Blue Rock Springs and went on to identify Arthur Leigh Allen in a 1991 photo lineup with what he described as “no doubt in my mind” — an identification that was complicated by the DNA evidence that would later emerge. He died in 2022. Bryan Hartnell survived being stabbed six times at Lake Berryessa, completed his law degree, and went on to a long career as a public defender and later a criminal defence attorney. He has, in occasional interviews over the decades, given some of the most thoughtful first-hand commentary on the case available — refusing to identify suspects he is not sure of, refusing to be drawn into the more elaborate conspiracy theories, and continuing to insist on the basic dignity of the man and woman who were attacked alongside him on a hillside above a lake in Napa County in September 1969.
The retired detectives who worked the case are now mostly dead. Dave Toschi of the San Francisco Police Department, the most famous investigator on the case — the inspiration for the Steve McQueen character in Bullitt and for Mark Ruffalo’s role in Zodiac — died in 2018, having said in his final years that he believed the case would be solved one day and that he hoped he would live to see it. He did not. Ken Narlow of Napa, who worked the Lake Berryessa attack, died in 2010. George Bawart of Vallejo, who interrogated Allen in 1991, died in 2018. The case is being inherited, slowly and quietly, by detectives who were not yet born when the killings happened.
A Final Note
Whatever the Zodiac wanted from his audience, he did not get the most important thing he asked for, which was to be named. He remains, fifty-seven years after the first killings, formally anonymous. The man who wrote so many letters trying to ensure his place in American memory did, in the end, achieve a kind of fame, but it is a strange kind — fame as a symbol, a costume, a circle with a cross through it, attached to no actual face.
The case will probably be solved eventually. Advances in genealogical DNA analysis, of the kind that broke the Golden State Killer case in 2018, continue to produce identifications of cold-case offenders previously thought to be unfindable. There is still genetic material from at least some of the Zodiac letters on file with law enforcement. If the killer has descendants who have ever uploaded their DNA to a genealogical service — which, by the demographics of who uses those services, is probable — then there is a reasonable chance that a familial match will eventually be made. The investigators working the case in the present day are quietly confident that this will happen, though when it will happen they cannot say.
When it does, whoever the Zodiac turns out to be will probably be a profoundly ordinary man. That has been the lesson of almost every major cold case to be solved by genealogical DNA over the past decade: the long-pursued bogeymen turn out, again and again, to be retired tradesmen, accountants, bus drivers, men who had wives and grandchildren and unremarkable lives, men whose neighbours and colleagues never suspected. The Zodiac wanted to be a figure of mythic terror. When his name is finally known, he will probably turn out to have been something much smaller than that — a man with grievances, with appetites, with the same ordinary furniture of an ordinary life, who for a brief period in 1968 and 1969 did things that the rest of us spend our lives trying to understand and cannot.
The five people he killed will still be dead. The two who survived will, in most cases, no longer be around to see his name printed. The investigators who spent careers on the case will mostly be gone. What the eventual identification will provide is not justice in any meaningful sense — it is far too late for that — but at least the dispelling of a mystery that has, for far too long, allowed a murderer to retain the one thing he most clearly wanted. His anonymity is the last piece of his work still standing. It is worth, occasionally, remembering that.
