Hawley Harvey Crippen (September 11, 1862 – November 23, 1910), colloquially known as Dr. Crippen, was an American homeopath, ear and eye specialist and medicine dispenser who was hanged in Pentonville Prison, London, for the murder of his wife, Cora Henrietta Crippen. He was the first criminal to be captured with the aid of wireless telegraphy.[1]
Early life and career
Hawley Crippen was born in Coldwater, Michigan,[2] the only surviving child to Andresse Skinner[3] and Myron Augustus Crippen,[4] a merchant.[5] He was educated first at the University of Michigan's homeopathy school, then graduated from the Cleveland Homeopathic Medical College in 1884.[6] After his first wife, Charlotte Jane (née Bell), died of a stroke in 1892, Crippen entrusted his parents, living in San Jose, California, with the care of his son, Hawley Otto (1889–1974).[6]
Having qualified as a homeopath, Crippen started to practice in New York City. In 1894 he married his second wife, Corrine "Cora" Turner (born Kunigunde Mackamotski), a music hall singer who performed under the stage name Belle Elmore.[5][7] That same year, Crippen started working for prominent homeopath James M. Munyon, moving to London with his wife in 1897 in order to manage Munyon's branch office there.[5]
Crippen's medical qualifications from the United States were not sufficient to allow him to practise as a doctor in the United Kingdom.[8] He initially continued working as a distributor of patent medicines,[9] while Cora embarked on an ultimately failed stage career and socialised with a number of variety players of the time.[10]
After Crippen was sacked by Munyon in 1899 he worked for other patent medicine companies, ultimately being hired as the manager for the Drouet Institute for the Deaf. There he hired Ethel Le Neve, a young typist, in 1900. By 1905, the two were having an affair.[5] After living at various addresses around London, Crippen and his wife finally moved No. 39 Hilldrop Crescent, Camden Road, Holloway, where they took in lodgers to augment Crippen's meagre income. Cora had an affair with one of these lodgers, and in turn, Crippen took Le Neve as his mistress in 1908.[5]
Murder and disappearance
![](http://upload.wikimedia.org/wikipedia/commons/thumb/2/28/Belle_Elmore.jpg/170px-Belle_Elmore.jpg)
On the evening of 31 January 1910, Cora disappeared following a party at the Crippen residence at Hilldrop Crescent. Crippen claimed that she had returned to the US and later added that she had died and had been cremated in California. Meanwhile, Le Neve moved into Hilldrop Crescent and began openly wearing Cora's clothes and jewelry.
Police first heard of Cora's disappearance from her friend, the strongwoman Kate "Vulcana" Williams,[11] but began to take the matter more seriously when asked to investigate when two other friends, the actress Lil Hawthorne and her husband/manager John Nash, pressed their acquaintance, Scotland Yard Superintendent Frank Froest.[12] Crippen's house was searched, but nothing was found.
Under questioning by Chief Inspector Walter Dew, Crippen admitted that he had fabricated the story about his wife having died, claiming that he did so to avoid personal embarrassment because she had in fact left him and fled to the US with one of her lovers, a music hall actor named Bruce Miller. Dew was satisfied with Crippen's story. However, Crippen and Le Neve did not know this and fled in panic to Brussels, where they spent the night at a hotel. The following day, they went to Antwerp and boarded the Canadian Pacific liner SS Montrose, bound for Canada.
The couple's disappearance led police to perform further searches of the house. During the fourth and final search, they found the torso of a human body buried under the brick floor of the basement. William Willcox (later Sir William Willcox, senior scientific analyst to the Home Office) found traces of the toxic compound hyoscine hydrobromide (scopolamine) in the torso.[13] The remains were identified as Cora's by a piece of skin from the abdomen; the head, limbs and skeleton were never recovered. Her remains were later interred at the St Pancras and Islington Cemetery, East Finchley.
Transatlantic arrest

Meanwhile, Crippen and Le Neve were crossing the Atlantic aboard Montrose, with Le Neve disguised as a boy. Captain Henry George Kendall recognised the fugitives and, just before steaming beyond the range of his ship-board transmitter, had telegraphist Lawrence Ernest Hughes send a wireless telegram to the British authorities: "Have strong suspicions that Crippen London cellar murderer and accomplice are among saloon passengers. Mustache taken off growing beard. Accomplice dressed as boy. Manner and build undoubtedly a girl." Had Crippen travelled third class, he probably would have escaped Kendall's notice. Dew boarded a faster White Star liner, SS Laurentic, from Liverpool, arrived in Quebec ahead of Crippen, and contacted the Canadian authorities.
As Montrose entered the St. Lawrence River, Dew came aboard disguised as a pilot. Canada was then still a dominion within the British Empire. If Crippen, an American citizen, had sailed to the US instead, even if he had been recognised, it would have taken extradition proceedings to bring him to trial. Kendall invited Crippen to meet the pilots as they came aboard. Dew removed his pilot's cap and said, "Good morning, Dr. Crippen. Do you know me? I'm Chief Inspector Dew from Scotland Yard." After a pause, Crippen replied, "Thank God it's over. The suspense has been too great. I couldn't stand it any longer." He then held out his wrists for the handcuffs. Crippen and Le Neve were arrested on board Montrose on 31 July 1910. Crippen was returned to the UK on board the SS Megantic.[14]
Trial
![](http://upload.wikimedia.org/wikipedia/commons/thumb/7/70/Crippen-scar.jpg/170px-Crippen-scar.jpg)
Crippen was tried at the Old Bailey before the Lord Chief Justice, Lord Alverstone, on 18 October 1910. The proceedings lasted four days.
The first prosecution witnesses were pathologists. One of them, Bernard Spilsbury, testified they could not identify the torso remains or even discern whether they were male or female. However, Spilsbury found a piece of skin with what he claimed to be an abdominal scar consistent with Cora's medical history.[8][15] Large quantities of scopalamine were found in the remains, and Crippen had purchased the drug before the murder from a local chemist.
Crippen's defence, led by Alfred Tobin,[16][17] maintained that Cora had fled to the US with Bruce Miller and that Cora and Hawley had been living at the house only since 1905, suggesting a previous owner of the house was responsible for the placement of the remains. The defence asserted that the abdominal scar identified by Spilsbury was really just folded tissue, for, among other things, it had hair follicles growing from it, something scar tissue could not have;[18] Spilsbury observed that the sebaceous glands appeared at the ends but not in the middle of the scar.[8]
Other evidence presented by the prosecution included a piece of a man's pajama top, supposedly from a pair Cora had given Crippen a year earlier. The pajama bottoms were found in Crippen's bedroom, but not the top. The fragment included the manufacturer's label, Jones Bros. Testimony from a Jones Bros. representative stated that the product was not sold prior to 1908, thus placing the date of manufacture well within the time period of when the Crippens occupied the house and when Cora gave the garment to Hawley the year before in 1909.[18] Curlers, and bleached hair consistent with Cora's, were also found with the remains.[19]
![](http://upload.wikimedia.org/wikipedia/en/thumb/4/41/The_Trial_of_Dr-Crippen.jpg/220px-The_Trial_of_Dr-Crippen.jpg)
Throughout the proceedings and at his sentencing, Crippen showed no remorse for his wife, only concern for his lover's reputation. The jury found Crippen guilty of murder after just twenty-seven minutes of deliberations. Le Neve was charged only with being an accessory after the fact and acquitted.[5]
Although Crippen never gave any reason for killing his wife, several theories have been propounded. One was by the late Victorian and Edwardian barrister Edward Marshall Hall, who believed that Crippen was using scopolamine on his wife as a depressant or anaphrodisiac but accidentally gave her an overdose and then panicked when she died.[8] It is said that Hall declined to lead Crippen's defence because another theory was to be propounded.[20]
In 1981, several British newspapers reported that Sir Hugh Rhys Rankin claimed to have encountered Le Neve in Australia, where she told him that Crippen murdered his wife because she had syphilis.[21]
Execution
Crippen was hanged by John Ellis at Pentonville Prison, London, at 9 am on Wednesday 23 November 1910.[5][22][23]
Le Neve sailed to the US before settling in Canada finding work as a typist. She returned to Britain in 1915 and died in 1967.[24] At Crippen's request, a photograph of Le Neve was placed in his coffin and buried with him.[citation needed]
Although Crippen's grave in Pentonville's grounds is not marked by a stone, tradition has it that soon after his burial, a rose bush was planted over it. In the early 2000s, an investigation into Crippen’s case began with DNA expert David R. Foran, Ph.D., and forensic toxicologist John H. Trestrail III, BS Pharm, leading a team looking into the evidence presented by the prosecution. Inconsistencies in the evidence and suppressed documents caused James Patrick Crippen, the closest living male relative of Crippen, to formally request the British government pardon the doctor and repatriate his remains to America.[25]
Before he was executed, Crippen wrote an eerily prophetic letter to Ethel Le Neve. In it, he said, "Face to face with God, I believe that facts will be forthcoming to prove my innocence." It is claimed that modern forensic science has now fulfilled his prophecy.[25]
Crippen's guilt
Questions have arisen about the investigation, trial and evidence that convicted Crippen in 1910. Dornford Yates, a junior barrister at the original trial, wrote in his memoirs As Berry and I Were Saying, that Lord Alverstone took the very unusual step, at the request of the prosecution, of refusing to give a copy of the sworn affidavit used to issue the arrest warrant to Crippen's defence counsel. The judge without challenge accepted the prosecution's argument that the withholding of the document would not prejudice the accused's case. Yates said he knew why the prosecution did this but – despite the passage of years – refused to disclose why.[26] Yates noted that although Crippen placed the torso in dry quicklime to be destroyed, he did not realise that when it became wet it turned into slaked lime, which is a preservative,[27] a fact that Yates used in the plot of his novel The House That Berry Built.
The American-British crime novelist Raymond Chandler thought it unbelievable that Crippen could be so stupid as to bury his wife's torso under the cellar floor of his home while successfully disposing of her head and limbs.[28]
Another theory is that Crippen was carrying out illegal abortions and the torso was that of one of his patients who died and not his wife.[29]
Another theory put forward is that the torso was Belle's former lover killed by Belle herself due to her having a short fuse temper and psychotic behaviour, and that Crippen may or may not have known about it.[citation needed]
New scientific evidence
In October 2007, Michigan State University forensic scientist David Foran claimed that mitochondrial DNA evidence showed the remains found in Crippen's cellar were not those of his wife. Researchers used genealogy to identify three living relatives of Cora Crippen (great-nieces). By providing mitochondrial DNA haplotype, researchers were able to compare their DNA with that extracted from a microscope slide containing flesh taken from the torso in Crippen's cellar.[30][31] The original remains were also tested using a highly sensitive assay of the Y chromosome that found the flesh sample on the slide was male.[32]
The same research team also argued that a scar found on the torso's abdomen, which the original trial's prosecution argued was the same one Mrs. Crippen was known to have, was incorrectly identified. The scientists found hair follicles in the tissue which should not be present in scars, a medical fact which Crippen's defence used at his trial.[31] Their research was published in the August 2010 issue of the Journal of Forensic Sciences.[33]
However, the new scientific evidence for Crippen's innocence has been disputed.[34][35] In The Times, journalist David Aaronovitch wrote: "As to the body being male, well the American team was using a 'special technique' that is 'very new' and 'done only by this team' and working on a single, century-old slide, described by the team leader as a 'less than optimal sample'".[35] Foran responded by saying "tests showed unequivocally that the remains were male".[18]
Traces of the blonde hair found in curlers at the scene are now preserved in the Metropolitan Police's Crime Museum. Another researcher said they asked to be provided with samples from them for DNA testing, but the request has been denied several times.[18] However, New Scotland Yard was willing to test a hair from the crime scene for a fee, which in turn was rejected by the investigators as "over the top."[18] Researchers hypothesized that the police planted the body parts and particularly the fragment of the pajama top at the scene to incriminate Crippen. He[who?] suggests that Scotland Yard was under tremendous public pressure to find and bring to trial a suspect for this heinous crime. An independent observer points out that the case did not become public until after the remains were found.[18]
In December 2009, the UK's Criminal Cases Review Commission, having reviewed the case, declared that the Court of Appeal will not hear the case to pardon Crippen posthumously.[36]

- In the 1972 season of Australian TV soap opera, Number 96, a plot line involving the death of Sylvia Vansard (in which her estranged chemist husband and his mistress are the main suspects), deliberately homages the Crippen story. It was referenced in the official synopses provided to the screenwriters.
- The Crippen saga is the basis for 1982's The False Inspector Dew, a detective novel by Peter Lovesey.
- The 1989 BBC series Shadow of the Noose, about the life of barrister Edward Marshall Hall, includes an abortive attempt on Hall's part to defend Crippen (played by David Hatton).
