Questioning (Door-to-door interview)

  1. Ask open-ended questions.
    • What have you seen or heard that is out of the ordinary?
  2. Tell the neighbours as little information as possible.
  3. If a neighbour reports something relevant:
    • take a detailed statement if time permits
    • if time is crucial:
      • note the information
      • advise the witness that another officer will return
      • contact the investigators
  4. Ask (don't tell) the neighbour to avoid discussing their evidence with the media or others.
  5. Explain that facts only the witness, perpetrator, and police know can help separate fact from rumour.
