1. besides a drawing of the crime scene, what else should be included in the crime scene sketch?

1. what kinds of factors determine which type of packaging should be used for crime scene evidence? give an example.

Explanation:

1. Gun: Circumstantial (links to crime but not direct proof), Physical (tangible object), Class (can be part of a general type of guns), Individual (if unique markings).
2. Shoe - print: Circumstantial (implies presence but not direct), Physical, Trace (left - behind mark), Class (general shoe type), Individual (if unique treads).
3. Pollen: Circumstantial (links suspect to location), Biological, Trace, Class (type of pollen).
4. Written confession: Direct (admission of guilt).

The seven S's of crime scene investigation are:

1. Survey: Quick overview to understand the scene layout and potential evidence locations.
2. Secure: Protect the scene from contamination and unauthorized access.
3. Search: Methodically look for evidence using various techniques.
4. Sketch: Create a drawing of the scene with measurements and details.
5. Screen: Use tools like sieves to find small or hidden evidence.
6. Secure evidence: Package and label evidence properly for transport and storage.
7. Submit: Send evidence to the laboratory for analysis.
8. Besides a drawing of the crime scene, a crime - scene sketch should include measurements (distances between objects and reference points), a legend (explaining symbols used), and a compass direction (to show orientation).
9. Factors determining packaging for crime - scene evidence include the nature of the evidence (e.g., biological evidence needs air - tight containers to prevent degradation), size and shape (fragile or large items need special handling), and potential for cross - contamination (e.g., separating different types of evidence). For example, bloodstained clothing should be placed in a paper bag to allow it to breathe and prevent mold growth.
