A Witness Questionnaire is a document used to collect information from individuals who have knowledge of a particular incident or event. It is used in investigations to help build a case or to clarify facts. There are two main types of Witness Questionnaires: pre-Internet and post-interview questionnaires. Pre-interview questionnaires are designed to gather preliminary information on the witness, such as name, address, contact information, and any details about the event. Post-interview questionnaires are used to record the witness's statements after the interview has taken place. They may include questions about the witness's observations, opinions, and recollections of the event. Witness Questionnaires are an important part of any investigation and are used to ensure that all relevant information is collected.
