MEMORANDUM
DATE:
6 April 2020
TO:
CSI's GOMEZ, CAVARRA, JORDAN, PIERRE, STEENEKAMP
VIA eMail: thru Blackboard
FROM:
Prof. G C. Shoemaker
SUBJECT: A Question of Relevance
As you research the meanings for the terms and concepts in Assignments Nos 2, 3a, 3b, and 3c you may wonder what
the relevance any one or more of the terms have to do with anything involved with documenting a crime scene
photographically. Consideration of the following may be illustrative.
This "Flow Chart" includes most of the major concerns regarding equipment the CSI should be thinking about prior to
starting the photographic documentation of the scene. I have highlighted in bold face type items that I believe directly
relate to one or more of your words. As the course proceeds you will see more connections.
