It's quite possible the official brought the tubes with him to put samples in.
Does anyone know where he was in North Carolina, and what he was doing there?
As I recall from news stories, he was taking his son to start fall semester at a college there.
The "outdoorsman" label, while accurate, is a bit misleading as people are interpreting it as he was a bowhunter or hunter. (As a hunter, I have never heard of any form of anthrax in wild animals ...I suppose it is possible but I haven't seen any cases cited in all the articles I've read on this subject. Anyone know of a case of wildlife anthrax???)
Moot point, I suppose, as I doubt there were any deer or cows in the building where this happened.
