Identification and Comparison
1. IDENTIFY:
 What is the Unknown Exhibit (glass, hair, paint, soil, fibers, metal, etc.)
2. COMPARISON:
 Obtain a control sample
 Comparative Examinations of the Unknown Exhibit with a Control Sample to see if they originated from different sources.
 Conduct all possible comparative examinations.
 Conclusion: could the two samples have originated from a common source

Testify as an Expert Witness
 Report: The end fragment of tape removed from the roll of tape found at the residence of the suspect (Exhibit #12) and the tape fragment removed from the knife (Exhibit #5) were at one time an integral unit.
