      "question": "What is the primary theory regarding the killer?",
      "answer": "The most widely accepted theory is that an unknown intruder stalked the family, lived in the attic, and carried out the murders before residing on the farm for several days."
    },
    {
      "question": "Why were the murders not discovered immediately?",
      "answer": "The farm was isolated, and because the family led a secluded lifestyle, neighbors did not immediately realize that the family had stopped appearing in town."

    {
      "question": "Was there any theft reported at the farm?",
      "answer": "No, there was no evidence of theft or robbery, which is why the crime is often attributed to a motive other than simple material gain."
