How can an investigator develop an effective interviewing strategy?

An effective interviewing strategy is critical for an investigator to gather accurate and comprehensive information. Preparing questions in advance allows the investigator to create a structured framework that guides the conversation, ensuring that all essential topics are covered. However, being adaptable to the responses of the interviewee is equally important. This adaptability means that the investigator can probe deeper into unexpected areas of interest that arise, follow up on intriguing leads, and clarify ambiguities as they occur during the interview.

This two-pronged approach—having prepared questions while remaining open to evolving the dialogue based on the interviewee's answers—enhances the quality of the information obtained. It also helps in building rapport with interviewees, making them feel more comfortable and valued during the process, which can lead to more candid responses.

In contrast, relying solely on instincts may lead to inconsistent or incomplete interviews, conducting interviews in large groups can inhibit individuals from sharing openly, and using a single set of questions for all witnesses may overlook the unique aspects of each case or witness, preventing the investigator from gathering the most pertinent and nuanced information.
