Each murder case comprises of three parts.

The Incident phase: See the entire murder as it unfolds, from start to end. The keys needed to solve the mysteries surrounding the murder can always be found in the video itself.

The Reasoning phase: Put together the [Clues] and [Mysteries] found during the Incident phase and create a hypothesis in your cognitive space. You can create multiple hypotheses, but not all of them will be correct. Some things you uncover may lead you down the wrong path.

The Solution phase: Pin down the killer based on the hypothesis you created in the Reasoning phase. Select the correct hypothesis to determine the killer. When facing a trickier culprit, they may attempt to refute your claims, so strike back with your reasoning!
