Assignment 2: Identification of Suspects by Using Scientific Principles

Today, law enforcement can identify suspects by using disciplines based on scientific principles. Scientists use two main techniques—fingerprint comparison and DNA analysis—to determine whether the fingerprints or DNA samples found at a crime scene match those of a suspect.
