Ten years ago, in the wake of the September 11th attacks, the nation faced a second wave of terrorism: anthrax in letters mailed to news organizations and politicians.
Five people were ultimately killed and 17 others were sickened by exposure to the letters directed to The New York Post, Tom Brokaw at NBC News, Sen. Tom Daschle (D-SD), Sen. Patrick Leahy (D-VT), and others.
Drawing from recently released FBI and Justice Department documents, CNN's Joe Johns tells the story of the ensuing federal investigation.
It lasted seven years - along a path that included phony leads, blind alleys, and scientific hurdles. Finally, after a lucky break, the evidence pointed to a rogue scientist in one of the government’s most sensitive and secure labs, an man who proclaimed his innocence and took his own life before he was charged.
Could it happen again?
