PBS.org's Nova online provides a program that could be used on a course on Forensic science.
From the site: "Welcome to the companion Web site to the NOVA program "The Killer's Trail," in which a team of experts investigates the forensic evidence in the 1954 murder of Marylin Sheppard, one of the most famous unsolved crimes in the U.S. The program was originally broadcast on October 19, 1999."
