- Scene Assessment: The team starts by assessing the crime scene's overall situation, including securing it to preserve evidence and ensuring the safety of all personnel involved.
- Documentation: Detailed documentation is crucial. They photograph, sketch, and make written notes of the entire scene, including the layout, positions of objects, and any potential evidence.
- Evidence Collection: Forensic experts collect physical evidence, such as fingerprints, blood samples, hair fibers, weapons, and other items that might be relevant to the case. They use proper techniques and tools to prevent contamination.
- Trace Evidence: Specialized personnel collect trace evidence like fibers, soil, and gunshot residue, which can provide valuable clues about the crime's circumstances.
- Biological Evidence: Forensic biologists collect and preserve biological samples like blood, saliva, or tissue for DNA analysis, which can link suspects or victims to the scene.

- Digital Evidence: Digital forensic specialists can examine electronic devices such as computers or smartphones to recover data, including text messages, emails, or images relevant to the case.
