S2·E11 Postal Mortem

On October 15, 1985, two bomb explosions rocked Salt Lake City and resulted in two deaths. A third explosion occurred the next day; this time, the victim was injured but survived. As the investigation progressed, police came to believe the survivor was more than an innocent by-stander. When they turned to forensic science for help, they uncovered an almost unbelievable story of forgery, fraud and murder.
