Fitzgerald reveals how investigators constructed a personality profile from the bomber’s writings, identified the unusual turn of phrase that became a “linguistic smoking gun,” and used patterns in language and behavior to identify this notoriously elusive criminal mind.&amp;nbsp; Plus, an exclusive glimpse into a family’s traumatic moment when they discover their relative is a serial bomber. ### Archival audio courtesy of Videos For Change Productions Excerpt from documentary in progress &quot;Life Or Death&quot; featuring David Kaczynski and Linda Patrik,&amp;nbsp; Producers Mike Camoin and John Carlson.&amp;nbsp; This Is Your Brain With Dr. Phil Stieg https://thisisyourbrain.com <iframe title="Libsyn Player" style="border: none" src="//html5-player.libsyn.com/embed/episode/id/42551155/height/90/theme/custom/thumbnail/yes/direction/forward/render-playlist/no/custom-color/000000/" height="90" width="600" scrolling="no" allowfullscreen webkitallowfullscreen mozallowfullscreen oallowfullscreen msallowfullscreen></iframe> https://assets.libsyn.com/secure/content/205425915
