2001 Anthrax Attacks Mailbox

The anthrax letters are believed to have been mailed from Princeton, New Jersey. In August 2002, investigators found anthrax spores in a city street mailbox located at 10 Nassau Street near the Princeton University campus. About 600 mailboxes that could have been used to mail the letters were tested for anthrax, and the Nassau Street box was the only one to test positive.
