The Cutting Edge of Forensic Science

Over a hundred years ago, searching for fingerprints became routine in crime scene investigation. In the intervening years the tools of forensic investigation have greatly evolved. Host Ben Kieffer speaks to Iowa State University Mechanical Engineer Daniel Attinger about his research for the U.S. Justice Department on bloodstain pattern analysis in crime scenes; then later forensic anthropologist Tyler O’Brien of the University of Northern Iowa joins the program. O’Brien specializes in studying the underwater decomposition of bodies and has consulted for various law agencies around the Midwest.
