The station was silent. Someone was still transmitting.
At 05:12 a.m., police systems analyst Elias Vane is found dead inside Relay Nine-a municipal radio station abandoned for nearly a decade.
The building is locked from within. Vane's analog watch stopped at 04:31. The station clock reads 04:47. An encrypted seven-channel signal continues broadcasting under Detective Lena Ortiz's credentials.
Six suspects had motive, access, or knowledge of the hidden network. Every one of them is hiding something-but only one committed murder.
In CASE: UNKNOWN #004, you become the detective. Examine crime-scene photographs, analyze forensic evidence, compare conflicting statements, reconstruct the timeline, and determine who killed Elias Vane before opening the sealed solution.
Inside the case file:
- 80 pages of reports, photographs, interviews, and evidence
- Six suspects with motives, secrets, and conflicting alibis
- Access logs, signal records, toxicology, and tunnel evidence
- Writable timelines, evidence boards, and accusation forms
- Three optional hints and a sealed step-by-step solution
- A detective performance score at the end of the investigation
The case can be solved as a standalone mystery. Returning investigators will also discover new evidence connected to the Meridian conspiracy running through the CASE: UNKNOWN series.
Designed for one to six players, ages 14 and up. Recommended investigation time: 60-90 minutes.
No app or game master required. Bring a pencil, follow the evidence, and trust nothing-not even the clock.
Can you decode the dead signal?
