Forensics: Crime Scene Detective — Case Rating Guide

Every case in Forensics: Crime Scene Detective receives a rating based on your investigative professionalism. Accuracy, precision, evidence completeness, and procedural compliance all factor into your score. This guide explains how ratings work and how to achieve the coveted S rank.

Rating Factors

• Evidence completeness — Finding every piece of relevant evidence at the scene.
• Chain of custody — Marking and photographing before collection.
• Lab thoroughness — Running all applicable analyses including secondary tests.
• Undiscovered leads — Zero missed clues when closing the case.
• Correct conclusion — Accusing the right suspect with supported evidence.

How to Get S Rating

1. Read all briefing materials and witness statements before starting.
2. Place markers and photograph every evidence item without exception.
3. Search all containers, trash bins, and hidden areas.
4. Run primary AND secondary lab analyses where available.
5. Check the evidence database for all recovered files.

Common Rating Killers

• Collecting evidence without prior marker placement and photography.
