Several anthrax letters were mailed from New Jersey
and at least one was mailed from Florida, not far from where Atta lived.
Ponder this before you think about anything else.
As I recall, the FBI profile begins with the notion it is one man. We extend that right away by identifying others that may be part of, or related to, the "cell." It indeed could be more than one perp!
As far as I know, the Florida letter has never been found and thus we don't know the postmark. If you have any information on that letter being found, please let us know!
Just a tidbit to tuck away in case it fits in later:
UM employee fired over Sept. 11 remarks
Mohammad Rahat worked as a research technician in two departments of the university (which may have antrax samples?): microbiology and immunology, and surgery/transplants. He was suspended on Sept. 20 and fired on Sept. 25, allegedly for his remarks. But did the universiy suspect him of stealing bacteria or using its facilities for personal projects? It wouldn't be the first "oops!" where an employee is fired for one reason, but the public is given another.
The first case of anthrax turned up in Miami. Did he send some of his "stock" to one of our physician "friends" in Chester? I would think it wouldn't be at all odd for a physician to get a package from the university.
