It verifies much more.
Not only the Steven's letter but others as well were mailed from St. Petersburg.
It is late at night, and I must go to bed, but I shall try to do a search tomorrow.
I remember very, very clearly it was reported that the letter to Stevens had a St. Petersburg postmark,
and this was before any of the other anthrax letters were sent.
Remember, the letter to Stevens was sent shortly after Sept. 11, weeks before the others.
I remember reading on this forum it had a St. Petersburg postmark
because reference was made to many Islamic radicals located at a university near St. Petersburg,
I even remember doing a map search at the time.
