Partly true. Ernesto Blanco, a mail clerk at AMI came down with symptoms that were diagnosed as something other than anthrax. But when Stevens was diagnosed with anthrax, they took another look at Blanco and decided he had anthrax, too.
Blanco was the only other person to show symptoms. One other person in the mailroom tested positive for exposure (they found spores in Stephanie Daley's nostrils), but she never showed any symptoms. And neither did anyone else at AMI. I think they handed out Cipro to anyone who felt they might have been exposed.
Thanks, Ed.
Took a quick look at your site, lots of info to glean through and I don’t have any details to add. Your comments seem to add to my belief this may have been a manufactured incident that either got out of hand or was planned that way. Just my un-knowledgeable opinion. :^)
