The Final Verdict

Instructions (Part I): Obtain an envelope of evidence taken from the crime scene and the suspects directly. Carefully remove the document evidence, fingerprint cards, and crime scene fiber sample. 

Instructions (Part II): Analyze the document sample using paper chromatography. Compare the fingerprint you lifted with the suspect prints on the provided cards, and examine the crime scene fiber sample under the microscope. Review your observations alongside your data to determine which suspect is guilty.
