Jack the Ripper (1888): Annie Chapman

Two forces worked the ground: the Metropolitan Police (H Division and CID) and, for the Mitre Square killing of Catherine Eddowes, the City of London Police. Named investigators include Inspector Frederick Abberline and, in later paperwork, Assistant Chief Constable Melville Macnaghten. Commissioner Sir Charles Warren resigned on 8 November 1888. The killer was never identified. Letters that gave the case its trade name — especially the “Dear Boss” letter of late September 1888 — are of disputed authenticity.

This page is an investigation and historiography file. It does not describe wounds, does not sexualise the dead and does not offer theories that could be read as a method. The victims were adult women living in East End poverty; several sold sex to survive. English-language culture later turned their deaths into a tourist brand. The public record is thinner than the brand.

Jack the Ripper is the type unsolved investigation: a short autumn of police work, a thick press myth and a century of documents that name suspects without ever producing a trial. The contemporary file is inquests, beat reports, medical statements that this page will not quote for injury detail, and a small set of letters sent to press and to the Whitechapel Vigilance Committee. There was no fingerprint bureau in 1888, no blood-group work that could individualise a stranger, and no surviving crime-scene photography of the kind later readers expect.
