Which type of interview focuses on gathering information from witnesses and victims?

The correct choice focuses on gathering information specifically from witnesses and victims, which is the primary goal of an informational interview. This type of interview is designed to collect relevant details about an incident or crime from people who have knowledge or experience related to it. The interviewer seeks to obtain factual data, observations, or personal accounts that can aid in the investigation or case.

In contrast, other types of interviews have distinct focuses. Alibi interviews are generally conducted to verify a suspect's claims about their whereabouts during an incident. Suspect interviews aim to gather information directly from individuals who are believed to be involved in criminal activity, often to determine their role or connections to the case. Interrogative interviews are more confrontational and are primarily used to elicit confessions or admissions of guilt from suspects. Each of these other types centers on different subjects or outcomes, making the informational interview uniquely suited for the purpose described in the question.
