What is the purpose of interviewing the complainant in missing persons cases?

The purpose of interviewing the complainant in missing persons cases is primarily to gain insight into the circumstances surrounding the disappearance. This involves understanding the context in which the person went missing, as well as the details that led up to the incident. The complainant can provide valuable information about the missing person’s last known activities, potential motives for disappearance, and any changes in behavior or context that may have occurred prior to the event. By understanding these circumstances, law enforcement and investigators can better assess the situation, determine the appropriate course of action, and apply their investigative techniques more effectively.

While gathering witness accounts, documenting relationships, and locating additional parties involved are all important aspects of a missing persons investigation, they largely serve as supplementary steps that stem from the initial insights gathered from the complainant's account. The complainant's insights are crucial to frame the case and guide further queries or investigations.
