Criminal Psychologist Linda Sage

What makes a killer? Is it nature or nurture? Not until Jack The Ripper and HH Holmes did the public even recognize the proclivity to kill in mass. 

We know it must have been a psychological need to kill throughout history but only in modern times has the human race begun to study and tear apart psychology.

 Our questions today are:  does culture and nurture change how people kill and more?

 Linda Sage is an expert on the psychology of serial killers and joins us today.
