Hi Ed,
What authority are you relying upon for your proposition that the letter with the powder was opened on the third floor, rather than the first floor? Thanks.
Relatedly, do you credit the CDC finding that there were two letters?
The National Enquirer, like Sun Magazine, is owned by American Media, Inc., which also owned the AMI building. The Enquirer provided a very detailed description of the whole J-Lo letter incident and how people handled it. It's HERE.
The only thing missing is an explicit statement that the managing editor of the Sun, Joe West, worked on the same floor as Bob Stevens and not in the mailroom.
