Who was Jack the Ripper?

Jack the Ripper was an unidentified serial killer who was active in the Whitechapel district of London, England, during the late 1800s. He is believed to have killed at least five women between August and November of 1888, all of whom were prostitutes. The killer’s identity has never been definitively determined, and the case remains one of the most infamous unsolved mysteries in history. The name “Jack the Ripper” comes from a letter sent to a London newspaper at the time of the murders, supposedly by the killer himself. The letter is now widely believed to have been a hoax. Despite numerous theories and investigations over the years, the true identity of Jack the Ripper remains unknown.
