Assign one of the following cases to each person in your group:

• Case 1: Presented shoe impression as evidence of special interest to the case.

Also, discuss some of the specific laboratory techniques that may be conducted to analyze the evidence. (If you are researching an older case, provide information about how that evidence might be analyzed today).
