For today's Forensics workshop, students learned about fingerprinting and the properties of finger prints that investigators examine. Students made fingerprints of their own fingers and then learned about different characteristics of fingerprints. They worked on characterizing their own fingerprints in order to practice the concepts. Then students learned about the process of "lifting" fingerprints from objects, using lotion to capture a clear form of their own fingerprints. Once they had practiced with their own prints, students worked to lift prints from the evidence found at the crime scene to learn more about the death of the victim. Students then practiced fingerprint identification with print sets from other members from the class, and also their own. Next, students worked to identify the fingerprints on the note. Then they learned about how fingerprints, among other evidence such as DNA, can be used to help describe the events that unfolded in a crime scene. Students were cautioned to remember that the strongest case is one that does not rely exclusively on one type of evidence such as DNA, because these alone still limit probabilities of events occurring, even if a small probability.
