Jack the Ripper: The Unsolved Murders That Still Haunt London

In the autumn of 1888, someone murdered at least five women in the Whitechapel district of London and was never caught. That alone wouldn’t have made the case famous. What did was the killer’s apparent taunting of the press and police, a nickname that stuck instantly, and a total absence of a satisfying ending. Over 130 years later, people are still arguing about who did it.
Whitechapel in 1888
To understand why the murders happened where they did, it helps to picture Whitechapel itself. It was one of the poorest, most overcrowded parts of London, packed with people surviving on casual labor, and a significant number of women turning to sex work simply to afford a bed for the night in a lodging house. Policing was thin, streets were poorly lit, and the fog rolling in off the Thames made visibility even worse after dark. It was, in a grim sense, close to ideal conditions for a killer who wanted to strike and disappear.
The Victims
Historians generally agree on five “canonical” victims, all killed within about ten weeks: Mary Ann Nichols, Annie Chapman, Elizabeth Stride, Catherine Eddowes, and Mary Jane Kelly. All were working-class women, and most were struggling with poverty and, in several cases, alcohol dependency at the time of their deaths.
The murders escalated in brutality as the string of killings went on. The final victim, Mary Jane Kelly, was killed indoors rather than on the street, which gave the attacker far more time alone with her. The result was so severe that even hardened police officers at the scene reportedly struggled to process what they found. It’s generally considered the most violent of the five murders, and many researchers believe it may represent the killer’s final act in London, whether by choice, by capture for an unrelated reason, or by death.
The Letters That Gave Him a Name
Journalists and police received hundreds of letters during the investigation claiming to be from the killer, the overwhelming majority almost certainly hoaxes written by the public or by newspapers looking to sell copies. One letter, signed “Jack the Ripper,” is the source of the name that stuck. A separate letter, sent along with what was reportedly half a preserved human kidney, was addressed to George Lusk, the head of a local vigilance committee formed by frustrated residents, and remains one of the more chilling pieces of evidence tied to the case, regardless of whether it was genuinely from the killer.
Whether any of these letters were actually written by the murderer is still debated. Most Ripper historians believe the majority, possibly all, were fabricated, and that the “Jack the Ripper” name may have originated with a journalist rather than the killer himself.
Why the Case Was Never Solved
Forensic science in 1888 was barely developed. Fingerprinting wasn’t yet used by London police, there was no concept of DNA evidence, and even basic crime scene preservation was inconsistent by modern standards. Investigators were largely limited to witness interviews, handwriting analysis on the flood of letters, and whatever physical evidence could be observed at the scene with the naked eye.
The case also generated enormous public panic and press coverage, which arguably made investigators’ jobs harder rather than easier. Newspapers competed for lurid detail, false leads multiplied, and the sheer number of “suspects” reported by an anxious public overwhelmed a police force already stretched thin.
The Suspects
Dozens of names have been proposed over the decades, ranging from plausible to wildly speculative. Aaron Kosminski, a Polish immigrant living in Whitechapel at the time, is one of the more frequently cited suspects and was named by at least one senior police official in later memoirs. Montague Druitt, a barrister whose family reportedly believed he was mentally unwell before his own death shortly after the murders stopped, is another commonly discussed name. American con man Francis Tumblety also drew attention from investigators at the time.
Other theories over the years have ranged from a member of the royal family to prominent artists and doctors, most of which modern historians treat with heavy skepticism due to thin or purely circumstantial evidence. A 2014 and 2019 claim involving DNA testing on a shawl allegedly linked to one victim pointed toward Kosminski, but the methodology and chain of custody behind that shawl have been challenged by other researchers, and the case is still officially considered unsolved.
The Legacy
Jack the Ripper effectively created the template for the modern true crime obsession. “Ripperology,” the informal field of research and amateur investigation into the case, is still active well over a century later, with new books, documentaries, and walking tours through Whitechapel appearing regularly. The murders also pushed London’s Metropolitan Police toward reforms in how homicide investigations were conducted, even though those changes came too late to catch the killer responsible.
What keeps the case alive isn’t just the violence. It’s the fact that it never actually ended. There was no trial, no confession, no final answer, just a killer who stopped, for reasons nobody has ever confirmed, and vanished into a fog that, in a way, never fully lifted.
