In the autumn of 1888, at least five women were murdered in the Whitechapel district of London by an unidentified assailant who came to be known as "Jack the Ripper," a name taken from a letter sent to a news agency claiming responsibility for the killings, though its authenticity has never been confirmed.
The Metropolitan Police investigated extensively and considered numerous suspects, but no one was ever charged. The case received enormous press coverage at the time, contributing to its enduring notoriety.
Over more than a century, dozens of theories and named suspects have been proposed by writers and amateur investigators, none of them conclusively proven. This page does not endorse or name any individual theory, as none has been established as fact.
The case remains formally unsolved and is considered one of the most studied cold cases in criminal history.
