As you read through the required materials for this week you should come to realize that when approaching and managing a crime scene, each type of physical evidence requires different techniques for identifying, documenting, and collecting that evidence.

Choose a specific type of physical evidence. Find two credible sources that relate to your chosen type of evidence. As you complete your post, keep in mind that the chain of custody must be maintained for all evidence. Include the following elements in your initial post:

Examine how that type of evidence is recognized and identified at the crime scene.

Specify how the position of that type of evidence is documented with relation to the overall crime scene.

Specify how that evidence is collected from the crime scene.

Discuss any field tests used for your chosen type of evidence.

Your initial post should be at least 250 words in length using APA 6th edition formatting. Support your claims with examples from the required material(s) and/or credible sources, and properly cite any references.
