In response to criticisms that the FBI’s case contains no evidence placing Ivins in New Jersey, where the anthrax letters were sent, The Washington Post published an article — headlined “New Details Show Anthrax Suspect Away On Key Day” — which, based on leaks from “government sources briefed on the case,” purported to describe evidence about Bruce Ivins’ whereabouts on September 17 — the day the FBI says the first batch of anthrax letters were mailed from a Princeton, New Jersey mailbox. The Post reported:
A partial log of Ivins’s work hours shows that he worked late in the lab on the evening of Sunday, Sept. 16, signing out at 9:52 p.m. after two hours and 15 minutes. The next morning, the sources said, he showed up as usual but stayed only briefly before taking leave hours. Authorities assume that he drove to Princeton immediately after that, dropping the letters in a mailbox on a well-traveled street across from the university campus. Ivins would have had to have left quickly to return for an appointment in the early evening, about 4 or 5 p.m.
The fastest one can drive from Frederick, Maryland to Princeton, New Jersey is 3 hours, which would mean that Ivins would have had to have dropped the anthrax letters in the New Jersey mailbox on September 17 by 1 p.m. or — at the latest — 2 p.m. in order to be able to attend a 4:00 or 5:00 p.m. meeting back at Ft. Detrick. But had he dropped the letters in the mailbox before 5:00 p.m. on September 17, the letters would have borne a September 17 postmark, rather than the September 18 postmark they bore (letters picked up from that Princeton mailbox before 5 p.m. bear the postmark from that day; letters picked up after 5 p.m. bear the postmark of the next day). That’s why the Search Warrant Affidavit (.pdf) released by the FBI on Friday said this (page 8):
If the Post‘s reporting about Ivins’ September 17 activities is accurate — that he “return[ed to Fort Detrick] for an appointment in the early evening, about 4 or 5 p.m.” — then that would constitute an alibi, not, as the Post breathlessly described it, “a key clue into how he could have pulled off an elaborate crime,” since any letter he mailed that way would have a September 17 — not a September 18 — postmark. Just compare the FBI’s own definition of “window of opportunity” to its September 17 timeline for Ivins to see how glaring that contradiction is.
The FBI’s theory as to how and when Ivins traveled to New Jersey on September 17 and mailed the letters is simply impossible, given the statement in their own Probable Cause Affidavit as to “the window of opportunity” the anthrax attacker had to mail the letters in order to have them bear a September 18 postmark. Marcy Wheeler and Larisa Alexandrovna have now noted the same discrepancy. That is a pretty enormous contradiction in the FBI’s case.
