The Tamam Shud Case: Who Was the Somerton Man?

On the morning of 1 December 1948, people arriving at Somerton Beach in Adelaide found a man lying against the seawall. He was well dressed — brown trousers, a European-style tie, polished shoes. No signs of struggle. No signs of trauma. He looked almost peaceful, except that he was dead. Police were called. And when they began the routine work of identifying him, they ran into something that was not routine at all. Every label had been cut from every item of clothing. His jacket, his shirt, his trousers — stripped clean. There was no wallet. No identification of any kind. A man had apparently gone to considerable trouble to ensure that, if found, he would not be known. This was not carelessness. It was a system. And it turned a death into a mystery that would take 74 years to partially unravel. The deliberate erasure of identity is the engine of the entire case. It is what transforms a sad and ambiguous death on a beach into something investigators and researchers have never been able to leave alone. Within days, police found a suitcase in the cloakroom at Adelaide Railway Station that appeared to belong to the same man — it contained clothing that matched what he wore, shaving equipment, a sharpened pair of scissors, and a table knife modified into a short sharp instrument. Every label in that suitcase had also been removed. The thoroughness of it suggested a plan, not an oversight. Someone had thought this through. He was well-nourished, somewhere between forty and fifty years old, with unusual physical characteristics — calf muscles suggestive of someone accustomed to wearing high-heeled boots, and a particular arrangement of his toes noted by pathologists as anatomically uncommon. His fingerprints matched nothing on file. No one who came forward at the time could name him. Then the autopsy results came back. And they deepened the mystery rather than resolving it. The man's spleen was three times its normal size. His stomach was congested with blood. Pathologists found signs consistent with rapid poisoning — the kind of internal disruption that a fast-acting toxic substance can produce. Yet no toxic substance was ever found. Not then, not later. The coroner eventually concluded that a massively toxic agent, undetectable by the methods available at the time, was probably responsible. But that conclusion came ten years after the body was found — in 1958 — and even then, the coroner's final words were unambiguous in their ambiguity. The report stated explicitly that the coroner was unable to say who the deceased was, unable to say how he died, and unable to say what caused his death. A spleen three times its normal size. It sounds like evidence. And in one sense it is — it tells us the body underwent something catastrophic in its final hours. But no substance that could explain it was ever identified. That gap between the physical sign and the absent proof is where the case has lived for decades. Several months after the body was found, during a re-examination of the clothing, investigators discovered something they had missed. There was a small, hidden fob pocket sewn into the waistband of his trousers. Inside it was a tiny scrap of paper. Printed on it, in clean type, were two Persian words: Tamam Shud. It is finished. It is over. The phrase comes from the final page of the Rubaiyat of Omar Khayyam, a collection of twelfth-century Persian verses that had become widely popular in the English-speaking world through Edward FitzGerald's translation. That scrap became the name by which the whole case is known. Microscopic testing identified it as having been torn from a particular rare edition of the Rubaiyat — a New Zealand printing. Police appealed for any copy of that edition to come forward. And then, in a development that widened the mystery considerably, an anonymous man — referred to by police under the pseudonym Ronald Francis — produced a copy of exactly that edition. He said it had been found in the back of an unlocked car in Glenelg, a suburb near the beach where the body had been discovered. Microscopic examination confirmed that the paper and tear pattern of the scrap matched the copy he handed in. The scrap had come from this book. The identity of Ronald Francis has never been revealed. Police have protected it from the beginning, and it has stayed protected ever since. But the book itself contained more. Detective Sergeant Lionel Leane examined the back pages and found faint indentations — someone had pressed hard enough on a previous page to leave marks. When those marks were enhanced, they revealed five lines of capital letters in an irregular pattern. They have never been deciphered. Cryptographers, military intelligence officers, and amateur investigators across seven decades have tried. None has produced a reading that has been accepted. The code, if it is a code, remains exactly as illegible today as it was in 1949. There was also a phone number. Unlisted. Written in the same back pages of the Rubaiyat. Police traced it to a woman named Jessica Thomson — known to her friends as Jo. She was a nurse. She lived on Moseley Street in Glenelg. And Glenelg is approximately 400 metres from where the body was found on Somerton Beach. Police asked Thomson directly what she made of that proximity. She said she did not know the dead man. She could not account for how her unlisted number came to be in the back of that book. She offered a lead, though: she told police she had given a copy of the Rubaiyat to a man named Alfred Boxall, at a hotel in Sydney, in 1945. It seemed significant. Police tracked down Alfred Boxall. He was alive, living in Sydney. And when they found him, he still had his copy of the Rubaiyat. Intact. Thomson had indeed given it to him. But it was not the rare New Zealand edition. That line of investigation — the idea that Boxall might be the connection between Thomson and the dead man — collapsed immediately. Thomson continued to deny knowing the Somerton Man for the rest of her life. The retired detective Gerry Feltus, who spent years investigating the case and wrote the only published book on it, interviewed Thomson in 2002. He found her either evasive or simply unwilling to share what she knew. Her daughter later told investigators she believed her mother had known who the dead man was. Thomson herself died — sources give conflicting dates, somewhere between 2007 and 2013 — without clarifying anything. What did Jo Thomson actually know? It is one of the questions the case will probably never answer. The body was embalmed and held for years, in the expectation that someone would eventually identify it. No one did. He was buried in West Terrace Cemetery in Adelaide in 1949. For more than 70 years, his grave was marked with a plaque bearing no name — only the date and the words by which the case had come to be known. Then, in October 2019, the Attorney-General of South Australia gave conditional approval for an exhumation. The formal dig took place on 19 May 2021. Samples were taken from the remains. But the DNA work that led to a named identification did not come from those samples alone. It came from an object made decades earlier, in the days just after the body was found. A sculptor named Paul Lawson had made a plaster cast of the Somerton Man's face — a death mask, a standard practice of the era for unidentified remains. That mask had been kept in storage. When researchers examined it, they found something unexpected: hairs trapped in the plaster. Root-end hairs. The kind that can yield nuclear DNA. Professor Derek Abbott of the University of Adelaide and genealogist Colleen Fitzpatrick extracted a DNA profile from those hairs. What they did with it next is where the modern chapter of this story begins. Forensic genetic genealogy is a technique that has transformed what is possible in cold-case investigation. It is worth understanding what makes it different from conventional DNA forensics. Standard forensic DNA testing looks at around 20 locations in the genome — short tandem repeats, or STRs — that vary between individuals. It can confirm or exclude a match with a known suspect or relative. But it requires a reasonably close relative, and it requires that relative to be on file somewhere. Forensic genetic genealogy instead reads a much larger panel of the genome — hundreds of thousands of points where the DNA sequence varies between people, called single nucleotide polymorphisms. That breadth means it can detect shared ancestry with relatives as distant as third or fourth cousins. And when those distant relatives have uploaded their own DNA to public genealogy databases, the technique can find them. The arrest of the Golden State Killer in April 2018 showed the world this method worked. Since then, hundreds of cold cases involving unidentified remains or unsolved crimes have been approached using the same technique. Case by case, it is resolving a whole class of mysteries that conventional forensics could not touch. Abbott and Fitzpatrick applied it to the Somerton Man's DNA. They searched public genealogy databases and found partial matches — distant cousins on both his paternal and maternal lines. From those matches, they began constructing a family tree. They worked outward from the matches, and inward from historical records. Birth certificates, marriage records, census data. The tree grew to approximately 4,000 people — mapped and connected before the branches could be made to converge on a single candidate. That candidate was Carl Webb. Carl "Charles" Webb. Born 16 November 1905 in Footscray, a suburb of Melbourne. His profession: electrical engineer and instrument maker. Abbott and Fitzpatrick announced the identification on 26 July 2022. They had found matches for descendants of two distant cousins — one on each side of the family. The triangulation pointed consistently to Webb. South Australia Police did not immediately confirm the finding. Their statement at the time said they were cautiously optimistic that this might provide a breakthrough. As of the information available through 2024 and 2025, they and Forensic Science South Australia were still working to formally verify the DNA results using their own forensic samples from the exhumation. That distinction matters. Abbott and Fitzpatrick's work is research — rigorous, peer-reviewed in its methods, and consistent with how forensic genetic genealogy has been applied in hundreds of other cases. But official confirmation is a separate process, conducted by the institutions that hold legal standing in the case. Until that confirmation comes, Carl Webb remains a named candidate — a very strong one, by the researchers' account — but not a formally established identity. Forensic genetic genealogy at this degree of distance — fourth cousins and beyond — identifies a lineage. It narrows the field dramatically. But it relies on the completeness of the family tree, and on the absence of other individuals in that tree who might also fit. The South Australian authorities have to satisfy themselves, with their own samples, that the same result holds. That process is apparently still underway. And even if Carl Webb is formally confirmed as the Somerton Man, that confirmation does not carry the rest of the answers with it. The five-line code has not been read. The family tree of 4,000 people tells us a name and a birthdate; it does not tell us what brought an instrument maker from Melbourne to Somerton Beach in December 1948, or why he arrived with every label removed from his clothing. Abbott has theorised that Webb may have come to South Australia to find his estranged wife. That is a theory. It is not established in the evidence. What is established, in the pathological sense: a spleen three times normal size. Signs of rapid internal disruption. No poison identified. No cause of death ever formally declared. Abbott and Fitzpatrick have said they lean toward suicide by poisoning. But no evidence of foul play has been proved either. The man on the beach could have died by his own hand, or by someone else's, or by something else entirely — and nothing found so far has closed that question. We began with a scrap of paper reading "it is finished," hidden in a pocket sewn into the waistband of a man with no name. If Abbott and Fitzpatrick are right, that man was Carl Webb — an instrument maker from Melbourne, born in Footscray in 1905. If the formal verification follows, then the mystery of who he was may finally be settled, just as those two words said. But the plaster death mask that gave up his hair still sits in evidence. The five-line code pressed into the back pages of a rare book has never been read by anyone who could explain what it means. And the question of whether Carl Webb walked onto Somerton Beach alone, or whether someone helped him die there, remains exactly where it was in 1948. What the case is waiting for now is a formal answer to the one question that sits between research and record: has South Australia Police verified the Carl Webb identification — and if they have, does that tell us anything at all about why he died?
