Frederick Abberline
Metropolitan Police inspector
The CID officer English readers most often meet. He worked the ground in 1888 and later gave interviews that fed, but did not close, the suspect literature.

Quick answers
Who was Jack the Ripper?
An unidentified murderer of adult women in Whitechapel in 1888. The name comes from press letters, not from a charging document. No one was convicted. Status is unsolved.
Who were the canonical five?
Mary Ann Nichols (31 August), Annie Chapman (8 September), Elizabeth Stride and Catherine Eddowes (30 September) and Mary Jane Kelly (9 November), all 1888. Macnaghten’s 1894 memorandum fixed the five-victim claim that later historians call canonical. Other Whitechapel murders in 1888–91 are in the wider police file.
Were the victims adult women?
Yes. The canonical five were adult women living in East End poverty. Several sold sex to survive. This page does not sexualise them or describe their bodies. They are named because the inquests named them.
Why was the case never solved?
No suspect was charged with the series. Forensic tools of 1888 could not individualise a stranger. Witness descriptions conflicted. Letters confused the public file. Later memoirs named names without producing trial evidence.
Are the Jack the Ripper letters genuine?
Some may be. Many are not. The “Dear Boss” letter that supplied the name is often judged a possible journalist’s hoax. The “From Hell” letter to George Lusk is debated separately. Hundreds of other letters are treated as copycat or crank mail.
Did DNA identify the killer?
No court has accepted such an identification. A 2014 mitochondrial-DNA claim tied to a disputed shawl and to Aaron Kosminski was criticised for chain of custody and for the limits of that DNA type. It did not close the case.
The dead were adult women with names. The living file is officers, a vigilance chair and later memoirists.
Suspect names in folklore are omitted here unless they appear in dated official paper.
People
Sir Charles Warren
Commissioner, Metropolitan Police
Resigned 8 November 1888 after a bruising autumn of press and Home Office conflict. His resignation is a political fact, not evidence of a hidden culprit.
Sir Robert Anderson
Assistant Commissioner, CID
Later wrote that the killer had been identified as a Polish Jew, a claim historians treat as memoir, not as a charging decision. No trial followed.
Sir Melville Macnaghten
Assistant Chief Constable (from 1889)
Not on the 1888 murder teams. His February 1894 memorandum created the canonical five and the Druitt–Kosminski–Ostrog triad that still structures amateur debate.
George Lusk
Whitechapel Vigilance Committee
A local builder who chaired a citizen patrol and received the “From Hell” letter. He stands for the civil, not Scotland Yard, half of the 1888 response.
Thomas Bond
Police surgeon
Wrote to Anderson on 10 November 1888 linking the canonical victims in a medical opinion. Later writers used that letter as glue; it was not a conviction.
Officers left paper. The killer left no name that a court would take.
