    {
      "question": "Who was Jack the Ripper?",
      "answer": "Jack the Ripper was the pseudonym given to an unidentified serial killer who was active in the impoverished areas in and around the Whitechapel district of London in 1888. He is believed to have murdered at least five women, known as the canonical five."
    },
    {
      "question": "How many victims did Jack the Ripper have?",
      "answer": "While there are numerous theories, five victims are generally accepted as the 'canonical' victims of Jack the Ripper. These are Mary Ann Nichols, Annie Chapman, Elizabeth Stride, Catherine Eddowes, and Mary Jane Kelly. Other murders have been suggested, but lack definitive links."
    },
    {
      "question": "Why is Jack the Ripper still unsolved?",
      "answer": "The case remains unsolved due to a combination of factors including the lack of modern forensic techniques at the time, the chaotic environment of Whitechapel, jurisdictional disputes among police forces, and the intense, often misleading, media coverage that obscured factual investigation."
    },
    {
      "question": "What evidence exists against Jack the Ripper?",
      "answer": "Evidence is scarce and largely circumstantial. It includes contemporary newspaper reports, witness accounts (often unreliable), letters purportedly from the killer (like the 'Dear Boss' letter), and the nature of the crime scenes themselves. A portion of a kidney sent to Mr. Lusk is one piece of evidence associated with the case."
    },
    {
      "question": "What was the impact of the media on the Jack the Ripper case?",
      "answer": "The media played a significant role in sensationalizing the murders, popularizing the name 'Jack the Ripper,' and creating a climate of fear and speculation. This intense interest often made it difficult to distinguish between fact and fiction, hindering the official investigation."
