Forensics: Crime Scene Detective — Tutorial 2: Another Robbery

Tutorial 2: Another Robbery focuses on systematic evidence collection across a crime scene. You practice the full documentation workflow — markers, photographs, inspection, collection, and packaging — while learning to submit evidence for colleague evaluation.

Core Skills Practiced

• Placing evidence markers before any physical contact.
• Taking clear photographs with markers visible for scale.
• Inspecting objects for trace evidence (fingerprints, biological material).
• Selecting correct packaging containers for different evidence types.
• Submitting evidence via the lab email system for evaluation.

Step-by-Step Scene Investigation

1. Select the case from the filing cabinet and review the briefing.
2. Travel to the crime scene and survey the entire area before collecting.
3. Place markers on all visible evidence — do not prioritize obvious items only.
4. Photograph each marked item from multiple angles.
5. Inspect objects for fingerprints using UV lighting where appropriate.
6. Collect items with proper tools: tweezers for small objects, swabs for biological samples.
7. Package each item in labeled, barcoded containers.
8. Check trash bins and hidden areas before leaving the scene.

Laboratory Processing

At the lab, process each collected item at the appropriate workstation. Fingerprint evidence goes to the fingerprint examination grid. Biological samples go to DNA analysis. Submit key findings via email and wait for colleague responses — not every submission generates a reply, so prioritize your strongest evidence.

Earning a High Rating

The game tracks whether you followed proper chain of custody. Every piece of evidence must be marked and photographed before collection. Returning to the scene after closing is possible but lowers your rating. Use our Case Rating guide for detailed scoring tips.
