As Carla and Tyler, you'll use specific tools to aid in your investigation. These are often automatically equipped or contextually available when needed.

- UV Light: Carla's primary tool for revealing hidden bloodstains, fingerprints, and other forensic evidence at crime scenes. Press 'F' to toggle it on/off. Essential for thorough investigation.
- Camera: Used to photograph evidence at crime scenes, documenting findings for the case file.
- Notebook: Carla's notebook automatically records clues and observations. While not an interactive item, it represents her meticulous record-keeping.
- Walkie-Talkie/Radio: Used by the detectives to communicate with dispatch or other officers, requesting backup or reporting findings.
- Computer/Database: Accessing police databases or computers can provide background information on suspects or victims.
Mastering the use of the UV light is critical for Carla's chapters. Always sweep crime scenes thoroughly with it to ensure no piece of evidence is missed. The more evidence you gather, the stronger your case.
