Every cold case has an answer.
You've been assigned to the Cold Case Unit. Read the case file, follow the leads online, and use the answer key to test your theories. Each objective you solve opens a sealed envelope with new evidence, until you can name the killer.
1 · Read the file
Open the case and read your first objective. Every report, statement, photo and receipt could matter.
2 · Work the leads
Documents mention websites. Visit them through the Web Directory: social media, news, public records.
3 · Test your theory
Submit your answer and the evidence that proves it. Wrong? Dig again, or take a hint.
4 · Open the envelope
Each solved objective unseals new evidence. Solve the third to close the case.
