Using what you have learned in weeks 5-6 and your crime scene scenario, review your collected evidence and identify the evidence you would test for drug chemistry, firearms or toolmarks examination, and/or a comparative evidence analysis. Answer the following questions for each piece of evidence you have selected for any of these tests:
1. List and describe the items of evidence from the scenario suitable for drug chemistry, firearms or toolmarks examination, and/or a comparative evidence analysis.
2. Sticking with drug, firearms, toolmarks, and comparative evidence testing, what laboratory test(s) are you requesting for each item evidence identified in Question 1 and why?
3. What investigative question(s) do you hope to resolve with your laboratory tests?
Keep in mind that certain pieces of evidence may be considered for more than one laboratory test.
Your test “results” will be provided to you in your assignment feedback when you receive your grade.
