Examining the Evidence & Potential Tests You’ve now got your evidence from the crime scene back in the lab, and you’re ready to analyze it! The only problem is that your lab is short-staffed and low on funds. It looks like you’ll only be able to run four tests.

Examining the Evidence
Use the evidence you’ve collected and/or your notes and photographs to provide the following:

At least three physical properties for each piece of evidence. For pieces of evidence that are in the form of a representation, like a cardboard cutout, list possible physical properties that a real version of the item might have.
At least two sentences explaining why you think it would or would not be useful to determine the chemical properties of any of the evidence.
A paragraph discussing which pieces of evidence, if any, could have class characteristics or individual characteristics that would help the investigation. What are their possible class and individual characteristics, and how could you use those in the investigation? Some evidence classes to consider will be: physical evidence, documentation evidence, and demonstrative evidence.
Evidence Tests
Based on the evidence you collected at the crime scene, which four tests would you run, and on which items? Provide a short paragraph explaining your choices. Also, provide a paragraph that describes, in detail, how exactly each test would be carried out. You may choose from these tests:

DNA analysis
Fingerprint comparison
Toxicology analysis/drug testing
Glass analysis
Soil analysis
Hair analysis
Fiber analysis
Ballistic/firearm analysis
Blood spatter analysis
Impression evidence analysis
