The short answer
The store describes a UV flashlight, camera, magnifier, radio contact and an evidence board. The latest announcement expands UV and magnifier interactions.
Start from the observed trace
The premise names blood traces, fingerprints, recordings and personal belongings as evidence. These categories do not identify every interactable object or prove a particular suspect’s guilt. Record the visible clue before attaching an interpretation to it.

A useful personal evidence note
Suggested format: room label, object, tool used, exact observation and unresolved question. Keep an interpretation on a separate line. The notebook on My progress stores your own observations locally; it does not confirm that a theory is correct.
