Approaching and Managing a Crime Scene

Choose a specific type of physical evidence. Find two additional credible sources from the Ashford University Library, or another credible source, 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. The Scholarly, Peer Reviewed, and Other Credible Sources table offers additional guidance on appropriate source types. If you have questions about whether a specific source is appropriate for this assignment, please contact your instructor. Your instructor has the final say about the appropriateness of a specific source for a particular assignment.

Guided Response: Review several of your colleagues’ posts and respond to at least three of your peers by 11:59 p.m. on Day 7 of the week. You are encouraged to post your required replies earlier in the week to promote more meaningful and interactive discourse in this discussion forum. In your responses, review the chosen evidence and articles referenced by peers and ask them questions about the articles in relation to their initial post. Probe for more information from peers by asking thoughtful questions about their discussion of the identification, documentation, and collection of their chosen type of evidence.
