Investigative Considerations and Search Warrant Suggestions

Once the investigator has classified the offense (and thus the motive), the investigative considerations and search warrant suggestions can be used to give direction and assistance to the investigation. It should be emphasized that the considerations examined here are general suggestions and not ab- solutes that apply in every case.

There are ten basic steps to a crime scene search:

1.    Approach the scene.

2.    Secure and protect the scene.

3.    Conduct a preliminary survey.

4.    Narratively describe the scene.

5.    Photograph the scene.

6.    Sketch the scene.

7.    Evaluate latent fingerprint evidence and other forms of evidence.

8.    Conduct a detailed search for evidence, and collect, preserve, docu- ment the evidence.

9.    Make the final survey.

10.    Release the scene.

The forensic analysis of physical evidence of hair and fibers, blood, semen, and saliva can provide the basis for critical testimony in court (Moreau, 1987).
