What is the minimum identification information required from people interviewed during an investigation?

The minimum identification information required from individuals interviewed during an investigation is their full name and address. This information is essential for several reasons. It provides a clear way to identify and locate the person for follow-up interviews or law enforcement purposes. Full names ensure that there is no ambiguity regarding whom the investigator is speaking with, which is particularly important in cases where individuals may have similar names. An address allows law enforcement to establish a connection to the incident being investigated, whether that involves understanding the individual's relationship to the location or providing proper follow-up.

While other details such as occupation, hobbies, date of birth, nationality, and social media profiles might be useful in certain contexts, they are not as fundamental as a full name and address for the purposes of identification and accountability during an investigation.
