The woman who was killed by Anthrax in Connecticut was likely the mailer of atleast some of the letters.

Are you serious? She was a 94-year-old woman (and there is nothing in her background that would suggest a connection or a motive). I don't believe this one for a second.

She knew the four atleast one or two of the Pakistani men in Connecticut who were arrrested and released for their likely involved in the Anthrax murders.

She may have known nothing about what they were doing. She simply may have mailed the letters for them---not knowing anything about the Anthrax being in them.
