Behind-the-scenes of criminal profiling and what it takes to catch a killer

For centuries the world has been fascinated by serial killers. Who are they? What makes them tick? What do they choose to kill?

To try to answer those questions the authorities turned to one woman: Dr. Ann Wolbert Burgess.

Now a celebrated criminal psychologist, forensic nurse and researcher, Burgess began her seasoned career researching and gathering data about victims of sexual assault and the lasting trauma in rape victims.

In the early 1970s at Boston College, Burgess met Linda Lytle Holmstrom. The two began working together and set up a program at Boston City Hospital. Their goal was to meet with as many rape victims as possible.
