In a domestic violence investigation, which is a fundamental step?

• A. Determine what happened
• B. Predict future crimes without evidence
• C. Interview only the suspect
• D. Ignore evidence collection

Answer: (A)

Understanding what happened is the starting point for any domestic violence investigation because it establishes the actual events, who was involved, when and where it occurred, and how those pieces fit together. This factual picture anchors every subsequent decision, from safety actions for the victim and any children to determining what happened legally and what charges might apply.

When you focus on determining what happened, you set the direction for gathering information from multiple sources—victims, witnesses, and the scene itself—while also noting injuries, timelines, and any physical evidence. This careful construction of the incident helps you assess credibility, identify inconsistencies, and decide what needs to be preserved or photographed, what statements to collect, and what forensic steps to take. It also informs how you interview people, ensuring you don’t miss critical details or rely on a single perspective.

Other options don’t fit as the fundamental first step. Predicting future crimes without evidence relies on speculation rather than facts. Interviewing only the suspect neglects the victim’s account and other corroborating information, which can lead to an incomplete or biased understanding. Ignoring evidence collection undermines the integrity of the investigation and can jeopardize safety and outcomes.

So, determining what happened is the best starting point because it builds a solid factual foundation for the entire investigation.
