Aren't they speculating that this is a case of
inhalation anthrax? If so, I don't think it could be part of the DC stuff. Even though the poor woman is 90, it would still take thousands of spores to be inhaled...unless it was an envelope full of the junk.
For my part, right now I'm more concerned about ridding CT of the dreaded strain 'Pacifus maximus' that has been infecting this great state for too many years.
