What is a follow-up investigation?

• A. After the initial incident is reported
• B. After evidence has been destroyed
• C. After the preliminary investigation
• D. After charging decisions are made

Answer: (C)

A follow-up investigation is the continued fact‑finding that happens after the initial report and after investigators complete a preliminary look at the case. It’s the step where detectives pursue additional leads, re‑interview witnesses, gather more evidence, and fill in gaps to build a stronger, more complete picture before any charging decisions are made. This stage starts once the preliminary investigation indicates there may be enough to proceed, but the case still needs deeper verification and corroboration. If the incident has only just been reported, or if evidence has been destroyed, or if charging decisions have already been made, those situations aren’t follow‑up work—the follow‑up is the deeper investigation that comes after the preliminary findings.
