Analyse the Evidence
This is where the real detective work begins. Open every document, review the suspect statements, inspect photos, study timelines and look for the details that do not quite add up.
Cold Case Inc investigations are built to be non-linear, so there is no single path through the case. You decide what to read first, which leads to follow, and which evidence deserves a second look.
- Real case-file thinking: compare reports, timelines, alibis and witness accounts.
- Digital evidence: review CCTV, audio, messages, maps, profiles and hidden clues.
- Connect the dots: separate useful evidence from red herrings and build your theory.
Submit Your Detective Report
Once you’ve followed the evidence and reached a conclusion, it’s time to submit your final detective report. This is where you name the killer, explain your reasoning and prove that your theory actually fits the case.
Cold Case Inc is not just about guessing who did it. You need to connect the right clues, challenge the red herrings and show that you’ve understood the full story behind the crime.
- Make your case: present your answer like a real investigator closing the file.
- Instant feedback: find out whether your reasoning holds up or whether you’ve missed something important.
- Refine your theory: if you’re wrong, revisit the evidence and submit again when you’re ready.
Case Closed – Full Reveal
Solve the case correctly and you’ll unlock the full reveal. This is the final payoff: a complete breakdown of what really happened, why it happened, and how the evidence pointed to the truth all along.
Cold Case Inc cases do not just end with a right or wrong answer. You also get the full story behind the crime, including the crucial clues, the suspect’s real motive, and the reasoning that ties the whole investigation together.
- Final debrief: see the full explanation of the case and how the mystery is resolved.
- Story payoff: uncover the motive, timeline, contradictions and hidden truth behind the crime.
- Rewarding finish: experience the satisfaction of seeing every clue fall into place.
