Elizabeth Burton, Director of Post-Mortems at Baylor College of Medicine, talks with Todd about the decline in autopsies in the U.S. She attributes the fall in the number of autopsies to an illusion that modern technology eliminates the need for the procedure. She argues that autopsies should routinely be performed, as they serve to educate physicians and correct cause-of-death errors.She notes that post-mortems still reveal surprises in 30 to 40 percent of cases.

Todd is joined by David Perrett, a cognitive psychologist at the University of St. Andrews in Scotland, who studies people's level of attraction to certain faces and facial features. He has found that people tend to prefer faces that resemble their own, but in the opposite sex. He explains that this may be because the image subconciously registers as similar to their parents' visages.

Chief Instructor for Universal Tracking Service Joel Hardin talks with Todd about finding people through his tracking techniques. He explains that tracking involves literally retracing every footstep of the person to be found. Through close examination, every person leaves a trail that can be followed. In his career, he has successfully tracked over 5,000 people.
