a. (5) What opposing hypotheses arise as a result of the conflict? Articulate them.

3. (10) What physical evidence exists to differentiate between the opposing hypotheses that you proposed? For each piece of evidence that could differentiate between the hypotheses, indicate what result would favour which hypothesis.

4. Analyze those pieces of physical evidence that will differentiate between the two hypotheses.

a. (10) For each item that you examine, what results do you obtain? Use the conclusions that we covered in class specific to the item being examined (for example, the conclusions reached by fingerprint examiners, those reached by DNA analysts, etc.)

b. (5) Who or what is included as a potential source of each item of evidence that you examine?

c. (5) Who or what is excluded as a potential source of each item of evidence that you examine?

d. (10) How many other potential sources exist based on your exam of the evidence (is it an individualization, or class evidence)?

e. (5) Study Item 7 the bloodstain pattern from the ground. How would this pattern be classified? What characteristics of the evidence do you use to infer the classification? What possible actions would have produced this pattern?

5. Now, go back to your original outline of the stories and hypotheses.

a. (10)Which hypotheses are excluded as a result of your examination?

b. (10) Whose story is supported by each item of evidence that you examine? Why?

6. (10) Prepare a short synopsis of your evidence examination relating which part of each story is supported by the evidence, and which is refuted by the evidence?
