On September 12, 1803, the criminal senate of the Kammergericht in Berlin delivered its judgment on Sophie Charlotte Ursinus, the widow of a Prussian privy councillor. Four people had been put to her account. Her lover, a Dutch officer named Rogay, had died years earlier, and the two physicians who had treated him for months agreed that consumption had killed him. Her husband had died in 1800, and three well-known doctors who had attended him said he had not died of poison. Her aunt, Christina Regina Witte, had died in January 1801, and on her death the medical men were divided. The fourth person, her servant Benjamin Klein, was alive. He had fallen ill in her service, recovered, and talked.
The court took the doctors at their word wherever they spoke with one voice. It acquitted her outright of the deaths of her lover and her husband. On Klein it held the poisoning fully proven. On the aunt it held the poisoning highly probable and ruled that the circumstances justified what the Prussian law of the day called an extraordinary punishment. The sentence was confinement for life in the fortress at Glatz. A nineteenth-century account of the case, preserved by the Badische Landesbibliothek in Karlsruhe, sets the reasoning out count by count, and the pattern in it is plain. Where a physician had committed himself to a natural cause, the verdict followed the physician. Ursinus lived out her life at Glatz and died there on April 4, 1836.
That is the oldest case in a long line, and it states the problem in its simplest form. A death certificate looks like a medical opinion. In practice it is a permission. It lets a body be buried or cremated, it closes the file, and it settles the one question that would otherwise oblige anyone in authority to look. Once it is signed, reopening the matter means contradicting a doctor, and in several of the cases that follow, courts declined to do so even with the accused in the dock.
Harold Shipman did not need to persuade a doctor. He was the doctor. When Kathleen Grundy, 81, died in Hyde, Greater Manchester, on June 24, 1998, after a visit from him, Shipman certified the death and gave the cause as old age. On the same day a will in her name reached a firm of solicitors in the town, leaving her estate to her doctor. Her daughter refused to believe it, and that refusal, not any medical doubt, started the case that ended at Preston Crown Court on January 31, 2000, when a jury convicted him of murdering 15 of his patients and of forging the will. The Associated Press, reporting the trial’s approach in December 1999, reported that Shipman had signed the women’s death certificates himself, giving causes such as old age or cancer.
Three months before Grundy died, the paperwork had come close to catching him. On March 24, 1998, a doctor from another practice in Hyde telephoned the local coroner. Her colleagues routinely countersigned the second cremation certificate for Shipman’s patients, and she had counted 16 such forms for him in three months against 14 deaths in her own, much larger, practice. The coroner passed the concern to the police the same day. The Shipman Inquiry’s Second Report later traced what followed: a detective, a sample of medical records, and a medical adviser who reassured him on April 1. The inquiry went no further.
The statistical shape of his practice was described afterward by Professor Richard Baker of the University of Leicester, in a clinical audit for the Chief Medical Officer published in January 2001. Shipman’s patients, he concluded, were more likely than other doctors' to die in the afternoon, to die within half an hour of what was described as a collapse, and to die with Shipman present. Over his career Baker counted 297 more deaths certified by Shipman than would have been expected. The Inquiry under Dame Janet Smith concluded in July 2002 that he had killed at least 215 patients, the Associated Press reported at the time. None of those additional deaths was ever put to a jury.
The Inquiry’s Third Report, published on July 14, 2003, turned to the system itself. Certification and the reporting of deaths to coroners, Dame Janet wrote, "had failed to both deter Shipman from killing his patients and to detect his crimes after they had been committed." The second cremation certificate was "wholly inadequate as a safeguard against concealed wrongdoing." Her central proposal, independent medical examiners to scrutinize deaths, took two decades to arrive. The statutory medical examiner system and new death certification rules came into force across England and Wales on September 9, 2024, the Welsh Government announced.
What one doctor did alone in Hyde took several hands in postwar Tokyo. Miyuki Ishikawa, a licensed midwife, ran the Kotobuki maternity home in Shinjuku Ward with her husband. Mothers who could not raise their children, most of them born outside marriage, paid the couple to take the infants in. Many of those infants died of hunger. When one died, a doctor wrote the death certificate. Bunshun Online, in a 2026 account of the case, put the number of false certificates the couple obtained at close to 60. The doctor told the Asahi Shimbun in 1948 that the children were already beyond help when they were brought to him and that he had warned the couple repeatedly, according to the 1948 coverage as retold by the journalist Arata Koike and by Bunshun Online’s editors.
The certificates then passed to the Shinjuku ward office. Its sanitation section, which received death notices and issued burial permits, told the Asahi it had taken in 103 death reports from the home. Officials said they had thought the number strange. They had processed the reports anyway, and the Asahi, in a long article on January 21, 1948, called what had happened bloodless office work. The deaths came to light in Tokyo in January 1948, and the doctor who had signed the certificates was among those arrested. His fate after his arrest was not reported.
The courts dealt with a fraction of the dead. On October 11, 1948, the Tokyo District Court held that Ishikawa and her husband had jointly caused the deaths of five infants by omission, through malnutrition, on an indictment for murder, and sentenced her to eight years. On 22 further deaths it ruled the evidence insufficient. On April 28, 1952, the Tokyo High Court set that judgment aside and reduced her term to four years, and the Supreme Court upheld the result. In the Diet in June 1948, the legislator Jirō Arita argued that the case exposed a defect in the medical system and called for public medical examiners to establish the true cause of death, rather than leaving the question to the doctor who happened to be at hand. Ishikawa died in May 1987.
Amelia Dyer learned what the law could do to her long before it hanged her. Parliament’s Infant Life Protection Act of 1872 required people who took in infants for payment to register, and in 1879 Dyer was convicted under it and sentenced to six months' imprisonment with hard labour. The historian Joanna Bourke, in a 2021 Gresham College lecture, describes the offense as neglect; Wells Nub News, citing newspaper reports of the period, says the charge was failing to obtain the required licence. Bourke draws a lesson from what followed. After her release, she argues, Dyer stopped taking a weekly fee for each child and demanded a single payment instead.
The deaths that ended her career came to light at Reading in the spring of 1896. At the Central Criminal Court in May of that year she was convicted of the wilful murder of Doris Marmon, an infant of about ten weeks, the only indictment tried. She was hanged at Newgate on June 10, 1896. The other infants who passed through her hands were never counted with any confidence, and none of them was the subject of a verdict.
The most uncomfortable of these cases is the one in which the doctors were not careless. In March and April 1905, in the Goutte d’Or quarter of Paris, several small children of Jeanne Weber’s family died while she was looking after them. One death was put down to convulsions and another to diphtheria, and the doctor who saw her own son, who died three days later, attributed his death to the same illness, according to Judith C. Reveal’s entry on Weber in Women in World History. After an episode on April 5 involving a ten-year-old nephew in her care, who survived, his mother accused her, and Weber was charged. She was tried for the homicide of three children and the attempted murder of a fourth.
The defense, led by the advocate Henri Robert, rested on the testimony of the forensic physician Dr. Léon Thoinot, who told the court the children had died of natural causes. On February 7, 1906, she was declared not guilty. Thoinot and his mentor, Dr. Paul Brouardel, later published a report standing by their findings.
In 1907, living in the Indre under the name Madame Moulinet, Weber worked as a housekeeper. A boy in her employer’s household died on April 17. The attending doctor was suspicious, a second examination contradicted the first, and Weber was arrested on May 4, 1907. Thoinot was called in again. The boy, he declared, had died of typhoid fever, and in December 1907 she was released. A further child’s death in May 1908 was attributed to her, and on October 25, 1908, she was declared insane and committed to the asylum at Maréville, where she died in 1910. Women in World History counts eight children; the legal journal Actu-Juridique, in a 2024 article on the women killers of Paris, puts the number at ten. No court convicted her of any of them. At the one trial she faced, a senior forensic expert called the deaths natural, and the verdict followed him.
In South Africa the certificate came up against a jury and held its ground. William Alfred Cowle, Daisy de Melker’s first husband, died at home on the morning of January 11, 1923. In his book on the case, extracted by the Mail & Guardian in 2023, the writer Ted Botha describes a doctor at the bedside who considered poisoning among the possible causes and asked that the medicine bottle be handed to the police before any certificate was signed. The acting district surgeon then carried out a post-mortem, recorded a brain hemorrhage and chronic kidney disease, and concluded that either could account for the death. Cowle was buried the next day. Her second husband, Robert Sproat, died in 1927. Both men left her money, and the World Rugby Museum, writing about the case in 2018, records that the first husband’s doctor had been suspicious and that nothing further was done at the time.
In 1932 her son, Rhodes Cecil Cowle, 20, died in Johannesburg. The World Rugby Museum says Robert Sproat’s brother then went to the police. De Melker was charged with all three deaths and went on trial in Johannesburg in October 1932, before crowds that queued daily for seats, the columnist Peter Martin wrote in GO! & Express in 2024. In November 1932 the court convicted her of murdering her son by poisoning. On both husbands it held the evidence insufficient and acquitted her, as the Cape Argus, GO! & Express and the World Rugby Museum all report. She was hanged at Pretoria Central Prison on December 30, 1932, and she did not confess, the Mail & Guardian noted in 2006. The acquittals left the deaths of both husbands without any finding of murder. Botha, Martin writes, raises the possibility that she killed them and others; no court has said so.
Anna Marie Hahn, a Bavarian immigrant, was convicted in Cincinnati in November 1937 of the first-degree murder of Jacob Wagner, 78, by poisoning. The jury of eleven women and one man deliberated for three hours and gave no recommendation of mercy, according to the Supreme Court of Ohio’s history of the trial judge, Charles S. Bell, and Time reported that she was only the second woman sentenced to death in Ohio. She was electrocuted on December 7, 1938, the Clermont Sun recorded in 2020.
The case had begun not in Cincinnati but in Colorado Springs, where a hotel reported $305 worth of diamond rings stolen in August 1937. Hahn had visited the hotel with George Obendoerfer, an elderly Cincinnati cobbler, and he died the next day of poisoning, Time reported. That inquiry pulled the earlier deaths back into view. By August 19, 1937, she was under indictment for first-degree murder in two deaths of elderly Cincinnati residents, and the prosecutor’s office was examining at least eleven, the Associated Press reported in a dispatch printed by the Michigan Daily. Only one indictment was tried. The Supreme Court of Ohio’s page on Judge Bell says the evidence also showed she had killed three more men and harmed another in the same way. That is a statement in an official history, not a verdict, and none of those deaths went before a jury.
Four of Martha Ann Johnson’s children died in Georgia between 1977 and 1982. The three youngest, who died between 1977 and 1981 at about a year and a half, two years and three months, were certified as dying of sudden infant death syndrome twice and of a seizure disorder once, according to the Supreme Court of Georgia’s summary of the trial record. The fourth was Jenny Ann Wright, 11, who died in Clayton County on February 21, 1982. The state crime laboratory’s autopsy gave asphyxiation as the cause. Police told Johnson she was a suspect in all four deaths, and then, the court recorded, no action was taken until the case was reopened in 1988.
On July 3, 1989, in an interview recorded on audiotape and videotape at the Clayton County Police Department, Johnson admitted killing Jenny and her son J.W. Taylor. She denied harming the other two. She was tried only for Jenny’s death, testified that she had not killed her, and was convicted of murder and sentenced to life in May 1990.
The trial produced a ruling that bears directly on how series cases are built. Asked about the deaths of the other children, a biostatistician called by the prosecution, who was not a physician, told the jury that "about 5% of these cases, and this is a very conservative estimate, might be due to causes similar to SIDS." In Johnson v. State, decided on July 9, 1991, the Supreme Court of Georgia held that he should not have been allowed to give the estimate. There was no factual basis for the calculation, the court said, and no foundation for his knowledge of the causes of sudden infant death. It disapproved of the testimony and held the error harmless only because of Johnson’s confession. Johnson has not been tried for any of the three earlier deaths. In 2020 the Clayton County district attorney’s office said those children had died in Fulton County, so any charging decision belonged there. In January 2020 the State Board of Pardons and Paroles confirmed a tentative grant of parole, which the district attorney opposed, WSB-TV and 11Alive reported.
Diana Lumbrera’s children died one at a time across West Texas, and each death went down as something other than a crime. A pathologist attributed the first, in 1976, to a convulsive disorder, the Garden City Police Department’s account of the case says. The death certificate of her son Jose Lionel Garza, who died on February 13, 1978, listed "multiple natural causes," according to the Kansas Supreme Court. Her daughter Melinda Garza, who died on August 17, 1982, was certified as dying of acute viral bronchopneumonitis and acute heart failure. Other deaths were put down to aspiration and to blood poisoning. Each child had been insured.
The certificate that failed to arrive was the seventh. Her son Jose Antonio, 4, died in Garden City, Kansas, on May 1, 1990. A surgeon at the hospital was suspicious, the pathologist concluded that the death was not natural and gave asphyxia as the cause, and staff called the police. Lumbrera was charged with first-degree murder on May 5, 1990. A jury convicted her; the Kansas Supreme Court reversed the verdict in 1992 for cumulative trial errors; a second jury convicted her again in April 1993; and on March 10, 1995, the court affirmed. By then, the 1995 opinion records, she had also pleaded no contest in Texas to the murders of Jose Lionel and Melinda and had been convicted of both.
The 1995 opinion is unusually frank about how the Texas deaths were turned into evidence. Dr. Robert Bux, a Texas forensic pathologist, testified that he believed the two convicted deaths were "asphyxial deaths of one type or another," and he described a rule of thumb for unexplained infant deaths in one family: "the third empirically I’d call a homicide." Dr. Harry Wilson, a pediatric pathologist from Colorado, said that taken one at a time each of the two deaths was "an unexpected and unexplained death" he could not individually call a homicide. He had written that all seven deaths were homicides, and he agreed in court that the conclusion rested on the pattern. The medical findings in each child had not changed. What changed was that someone had lined them up.
Five elderly women who lived at Alpine Manor Nursing Home in Walker, a suburb of Grand Rapids, died in the late 1980s; the Michigan attorney general’s office later placed the killings in 1986 and 1987. All five had dementia or Alzheimer’s disease, and they were between 60 and 98 years old, ABC7 New York reported. Edith Cook, 98, died on April 7, 1987. The deaths were at first believed to be natural, the Associated Press reported in January 1989, and police began to investigate only when the former husband of Catherine Wood, a nurse’s aide at the home, came forward to report them as killings. By then Wood had been ordered to stand trial on two counts of open murder, for the deaths of Edith Cook and Marguerite Chambers, 60, and her co-worker and former partner, Gwendolyn Graham, had agreed to return from Texas to face a charge over Edith Cook’s death.
Wood pleaded guilty to second-degree murder and conspiracy and became the prosecution’s main witness. She testified that Graham had killed the women and that she herself had only kept watch. The medical evidence could not carry the case on its own. At Graham’s trial in Grand Rapids, United Press International reported, the medical examiner who had examined two of the women once the inquiry began could neither confirm nor rule out the cause the prosecution alleged. Graham testified that no one had been killed and that the two of them had invented the story to shock a co-worker. On September 20, 1989, a Kent County jury convicted her of five counts of first-degree murder and one of conspiracy, which carried a mandatory sentence of life without parole. Wood received 20 to 40 years in October 1989, and the judge told her that without her cooperation the case would never have been cleared up. She walked out of a federal prison in Tallahassee on January 16, 2020, WSOC-TV reported, after Michigan’s attorney general had warned that the parole board’s decision put public safety at risk. The case against Graham began with what Wood had said to her husband, and it rested on her account.
Kaspars Petrovs, a homeless man from the small western Latvian town of Grobiņa, was convicted of robbing and killing elderly women in Riga between 2000 and early 2003. Because the women were old, many of the deaths were first taken for natural ones, Jauns.lv recalled in 2026. Relatives did not suspect a crime until after his arrest on February 3, 2003, and the news coverage that followed, the Latvian agency LETA reported at the opening of his trial; only then did they go to the police. In custody he confessed, and the confessions grew. The indictment read in the Riga Regional Court on February 9, 2005, listed 38 murders and eight attempted murders among 53 criminal episodes.
On May 12, 2005, the court sentenced him to life imprisonment. It convicted him of 13 murders. The Baltic Times reported that a lack of forensic evidence had limited the murder convictions to that number, and the newspaper Neatkarīgā wrote in 2007 that the court recognized fewer than half of the killings he had confessed to because of errors by police and medical examiners, leaving 23 deaths with no one held responsible. His confessions reached those deaths; the proof did not. In February 2026 Jauns.lv placed him in the prison known as Baltais gulbis, the White Swan.
The death of Sally White came to light in Camden Town, north London, on January 20, 2002, when police called on Anthony Hardy over damage to a neighbour’s door. The pathologist who carried out the post-mortem examination saw no positive evidence of a cause and concluded that she had died of a heart attack. At St Pancras Coroner’s Court the coroner recorded natural causes, accepting coronary artery disease. Richard Osley of the Camden New Journal, who covered the hearing as a junior reporter, wrote in 2011 that it lasted about 15 minutes. Hardy was not called. Police had supplied only basic details, chiefly to allow the release of her body for burial, and the matter was classed as "No Crime," the paper reported; the Metropolitan Police later said its detectives had never been asked to attend.
Hardy was dealt with for the damage to the door. He was made subject to a hospital order and held at St Luke’s Hospital in Muswell Hill, which he left in early November 2002, Community Care reported. By the end of December two more women, Elizabeth Valad, 29, and Bridgette MacLennan, 34, were dead, and their deaths came to light in Camden Town at the end of that month. Hardy was charged with three murders, Sally White’s among them. On November 25, 2003, the day his trial was due to begin at the Central Criminal Court, he pleaded guilty to all three. In May 2010 the High Court made a whole life order, the Yorkshire Post and the Camden New Journal reported.
The first verdict was revisited only in disciplinary proceedings against the pathologist. In March 2011 a General Medical Council panel ruled that he had failed to give proper thought to the circumstances of Sally White’s death and to other possible causes, including asphyxia, Channel 4 News reported. Hardy died in hospital on November 25, 2020, aged 69, a prisoner of HMP Frankland. The hospital certified COVID-19 pneumonia, with type 2 diabetes and heart failure contributing, and according to the Prisons and Probation Ombudsman the coroner accepted the certificate without a post-mortem.
Olaf Däter, a 32-year-old former nurse, admitted at the opening of his trial before the Landgericht Bremen in November 2001 that he had killed five women aged between 82 and 89 in the Bremerhaven area between June 5 and June 12, 2001, and robbed them. They had known him personally. A sixth woman, 83, survived, and her account to police pointed investigators to him. In convicting him of five murders and one attempted murder, the court credited him with admitting one killing that had not at first been recognized as murder at all, the taz reported. Which death that was, and how it had first been recorded, has not been made public. Presiding judge Harald Schmacke observed that five women had died for a total of 1,480 marks. The sentence was life, with a finding of particular gravity of guilt. The Nordsee-Zeitung’s site nord24 described him in November 2017 as still serving it.
On April 14, 2023, Siriporn Khanwong, 32, died suddenly on a Buddhist merit-making outing in Ratchaburi province, west of Bangkok. Her family did not accept a natural death, and eleven days later police arrested her friend Sararat Rangsiwuthaporn on a warrant for premeditated murder. Within weeks Thai police had tied Sararat to a string of sudden deaths among the people who lent her money or shared savings circles with her, and on June 30, 2023, they announced fifteen cases between 2015 and 2023, fourteen of them fatal. The deputy national police chief, Surachate Hakparn, said she had planned the deaths over eight years so that they would look like heart attacks, CBS News reported with Agence France-Presse.
Bangkok’s Criminal Court took the cases one at a time. On November 20, 2024, it sentenced her to death for murdering Siriporn by poisoning with potassium cyanide, Khaosod English reported. By September 22, 2026, the court had convicted her of five murders, with three death sentences and two of life imprisonment, and had acquitted her in three cases, The Nation reported; every ruling is open to appeal, and she denies every charge. The acquittals are where the old paperwork told. In the case of Monthathip Khao-in, who died in Bangkok on July 7, 2015, the doctor who examined her had attributed the death to heart failure or an existing illness and could not confirm poisoning, and on August 4, 2026, the court dismissed the charge on reasonable doubt, The Standard reported. In the case of Nittaya Kaewbuppha, an engineer who died in Nakhon Pathom in August 2020, no cyanide test had been done at the time; on March 11, 2026, the court accepted that cyanide caused her death and still acquitted Sararat, citing unclear evidence that she had possessed the poison. A further judgment, in the attempted murder case of a woman who survived, was set for November 25, 2026.
Lay the endings side by side and medicine is rarely what ends them. A daughter would not believe a will. A colleague counted cremation forms. A hotel reported stolen rings. A former husband went to the police. A survivor gave a name. A family refused to accept a natural death. In several of these cases the medical evidence on the earliest deaths was no stronger at trial than on the day the certificate was signed, as the acquittals in Berlin, Johannesburg and Bangkok show. What changed was that someone had a reason to set each death beside the others.
That is also the danger. The reasoning that exposes a series can manufacture one, and the courts in these cases said as much. The Supreme Court of Georgia rejected a statistician’s estimate of the odds against natural infant deaths because it had no foundation. Harry Wilson told a Kansas jury that he could not call either of two Texas deaths a homicide on its own, only as part of a pattern. And in Paris a senior forensic expert looked at a row of dead children, called the deaths natural, and was believed. The certificate is a weak safeguard. It is also, in the end, the record that stands when a court cannot do better, and in Berlin in 1803, in Johannesburg in 1932 and in Bangkok in 2026, it did exactly that.
