1. Establishing the scene dimensions-establish an area that contains all relevant physical evidence.
2. establishing the scene security- controlling the person who enters or exits the scene,
3. Making a plan, communication and coordination- developing a theory
4. Conduct a primary survey- identification of potentially valuable evidence,
5. Process the scene-collecting the evidence
6. Record and preserve evidence-to make sure all evidence is accounted.
