Jack the Ripper mystery: Theory about identity of killer ‘revealed’ by newly discovered medical records

A former police volunteer claims to have discovered the identity of the figure behind some of the most shocking crimes in British history, unmasking the 19th-century murderer who terrorised the nation as Jack the Ripper.

Sarah Bax Horton – whose great-great-grandfather was a policeman at the heart of the Ripper investigation – has unearthed compelling evidence that matches witness descriptions of the man seen with female victims shortly before they were stabbed to death in 1888 in the East End of London.

Her detective work has led her to Hyam Hyams, who lived in an area at the centre of the murders and who, as a cigar-maker, knew how to use a knife. He was an epileptic and an alcoholic who was in and out of mental asylums, his condition worsening after he was injured in an accident and unable to work. He repeatedly assaulted his wife, paranoid that she was cheating on him, and was eventually arrested after he attacked her and his mother with “a chopper”.

Significantly, Bax Horton gained access to his medical records and discovered dramatic details. She told the Telegraph: “For the first time in history, Jack the Ripper can be identified as Hyam Hyams using distinctive physical characteristics.”

Witnesses described a man in his mid-30s with a stiff arm and an irregular gait with bent knees, and Bax Horton discovered the medical notes of Hyam – who was 35 in 1888 – recorded an injury that left him unable to “bend or extend” his left arm, as well as an irregular gait and an inability to straighten his knees, with asymmetric foot-dragging. He also had the most severe form of epilepsy, with regular seizures.

The victims’ throats were cut and their bodies butchered in frenzied attacks, with the authorities receiving taunting anonymous notes from someone calling himself ‘Jack the Ripper’. They are some of the most infamous unsolved crimes.

At least six women - Martha Tabram, Polly Nichols, Annie Chapman, Elisabeth Stride, Kate Eddowes and Mary Jane Kelly - were killed in or near Whitechapel between August and November 1888.

Hyams’ medical notes, taken from various infirmaries and asylums, reveal his mental and physical decline coincided with the Ripper’s killing period, escalating during the period between when he broke his left arm in February 1888 and his permanent committal in September 1889.

“That escalation path matched the increasing violence of the murders,” said Bax Horton. “He was particularly violent after his severe epileptic fits, which explains the periodicity of the murders.”

She added: “In the files, it said what the eyewitnesses said – that he had a peculiar gait. He was weak at the knees and wasn’t fully extending his legs. When he walked, he had a kind of shuffling gait, which was probably a side-effect of some brain damage as a result of his epilepsy.”

Witness accounts of the man’s height and weight were similar to the details in Hyams’ medical files, Bax Horton discovered.

“They saw a man of medium height and build, between 5′5 and 5′8. Tall, stout and broad-shouldered. Hyam was 5′7 and a half and weighed 10 stone, seven pounds ... His photograph demonstrates that he was noticeably broad-shouldered,” she said.

She has concluded that Hyams’ physical and mental decline – exacerbated by his alcoholism – triggered him to kill. The murders stopped at the end of 1888, around the time Hyams was picked up by the police as “a wandering lunatic”. In 1889, he was incarcerated in the Colney Hatch Lunatic Asylum, north London, until his death in 1913. Jack the Ripper never struck again.

Various suspects have previously been suggested as the man behind the killings, including the artist Walter Sickert, who painted gruesome pictures of a murdered prostitute.

Hyams had been on a “long list” of around 100 culprits, but Bax Horton said he had been discounted because he had been misidentified. “When I was trying to identify the correct Hyam Hyams, I found about five. It took quite a lot of work to identify his correct biographical data. Hyams has never before been fully explored as a Ripper suspect. To protect the confidentiality of living individuals, two of the Colney Hatch Asylum files on patients, including Hyams, were closed to public view until 2013 and 2015.”

What makes her research particularly extraordinary is that it was prompted by her chance discovery in 2017 that her own great-great-grandfather, Harry Garrett, had been a Metropolitan Police sergeant at Leman Street Police Station, headquarters of the Ripper investigation. He was posted there from January 1888 – the fateful year of the murders – until 1896.

Bax Horton, who read English and modern languages at Oxford University, is a retired civil servant who volunteered with the City of London Police for almost two decades until 2020. She had no idea of her ancestor’s history until she began researching her family and found herself studying the Ripper case.

She will now present her extensive evidence in a forthcoming book, titled One-Armed Jack: Uncovering the Real Jack the Ripper, to be published by Michael O’Mara Books next month.

It is written in tribute to her ancestor and his police colleagues.

Paul Begg, a leading Ripper authority, has endorsed it. “This is a well-researched, well-written and long-needed book-length examination of a likely suspect. If you have an idea of the sort of man Jack the Ripper might have been, Hyam Hyams could be it,” he said.
