When interviewing a fraud suspect, it is important to gather both subjective and objective information (Option 1). Subjective information can include opinions or perspectives, which may provide insights into motivations or behaviors, while objective information consists of factual data. The interviewer typically begins with open-ended questions (Option 3) to allow the suspect to provide information freely and without leading them to specific answers. The primary objective is to gather information rather than to obtain a written confession (Option 2), and video recordings, while beneficial in certain cases, are not always used and thus not a standard requirement (Option 4).
