What is the primary function of a suspect interview in an investigation?

The primary function of a suspect interview in an investigation is to understand the suspect's perspective and gather information. This approach allows investigators to obtain a comprehensive view of the events surrounding a crime and the suspect’s involvement. Conducting the interview with an aim to gather insights helps build a clearer timeline, identify potential witnesses, and unearth additional details that may assist in the investigation.

By fostering an environment where the suspect feels comfortable sharing information, investigators can encourage the suspect to provide their account of events. This can sometimes lead to the collection of significant details that might not be captured by other means. Engaging in a dialogue also opens the door for investigators to assess the suspect's credibility and motives, which are crucial for piecing together the narrative of the incident.

While obtaining a confession might be a goal in some contexts, it is not the primary function of the interview. Intimidation of a suspect could lead to unreliable information or silence, which would hinder the investigation rather than advance it. Additionally, although analyzing body language can provide insights, it should not be the focus of the interview. Instead, understanding the suspect's perspective and gathering their narrative remains the cornerstone of the investigative interview process.
