In this episode of Conspiracy Theories, Cults, & Crimes, host Vanessa Richardson examines the chilling bioterrorism attack that terrorized the United States in the weeks following September 11, 2001. As letters laced with deadly anthrax spores moved silently through the U.S. mail, journalists, postal workers, and government employees became unsuspecting targets—leaving five people dead and an entire nation gripped by fear. Vanessa breaks down how the attacks unfolded, why the mail system became a weapon, and how investigators navigated years of false leads, public panic, and scientific breakthroughs to identify the culprit. It’s a haunting look at paranoia, power, and how one person exploited national trauma to carry out the most infamous bioterror attack in American history.
