The FBI won’t close the investigation into the 2001 anthrax attacks that killed five people, reports National Public Radio. Today, FBI Director Robert Mueller will personally brief anthrax victims’ family members. It will mark the first time that the FBI reveals the evidence it has gathered to support its claim that Army scientist Bruce Ivins was behind the attacks.
Ivins was one of fewer than a dozen people with access to the particular supply of anthrax they now believe was used in the 2001 attacks that left five people dead. The FBI reportedly has amassed an exhaustive report of times Ivins entered and left the lab in the days and weeks before the deadly letters were sent. A source says logs show Ivins using the lab where the anthrax was present at times that could be viewed as suspicious, including late at night when he was there alone. Still, the FBI investigation appears, at least so far, to be largely circumstantial. A source who has been briefed on the case says the bureau has been unable to place Ivins in Princeton, N.J., or anywhere near the mailboxes where the letters were mailed at the time they were post-stamped. The source described the case as one based on “access and opportunity,” not direct evidence or even eyewitnesses.
