FBI CLOSES 2001 ANTHRAX CASE

*** Let us not forget the fake letter he wrote trying to blame Muslims for it. It was the most serious bioweapon attack on American citizens and clearly a terrorist act because of that. MS ***

WASHINGTON - After seven frustrating years probing the deadly 2001 anthrax mailings, the FBI closed the case Friday, concluding a mentally unhinged government researcher acted alone in the attacks that killed five people and unnerved Americans nationwide.

Many details of the case have been known, but newly released FBI documents paint a fuller portrait of Dr. Bruce Ivins as a troubled scientist whose career was teetering toward failure at the time the letters were sent. As the U.S. responded to the mailings, his work was given new importance by the government and he was even honoured for his efforts on anthrax.

The documents also describe what investigators say was Ivins' bizarre, decades-long obsession with a sorority. The letters were mailed from a mailbox near the sorority's office in Princeton, New Jersey.

The anthrax letters were sent to lawmakers and news organizations as the U.S.Ination reeled in the aftermath of the Sept. 11, 2001, terror attacks in which hijacked airliners were flown into the World Trade Center in New York and the Pentagon in suburban Washington. Postal facilities, Capitol buildings and private offices were shut down for inspection and cleaning by workers in hazardous materials "space suits" from Florida to Washington to New York and beyond.

The Federal Bureau of Investigation and Justice Department announced the decision closing the case while disclosing reams of evidence collected in the case. Officials also released a nearly 100-page summary of their findings.

The document said Ivins made comments to a former colleague that showed "immediately prior to the anthrax letter attacks, his life's work was in jeopardy."

Ivins killed himself in 2008 as prosecutors prepared to indict him for the attacks. He had denied involvement, and his family and some friends have continued to insist he was innocent.

Authorities say Ivins' death capped a years-long cat-and-mouse game with investigators, in which he repeatedly offered to help the FBI catch the killer, cast suspicion on his colleagues and tried numerous forms of subterfuge.

Authorities tried to build a case against biowarfare expert Steven Hatfill, but ultimately turned away from that and had to pay him a multimillion-dollar settlement.

After the attacks, the FBI relied heavily on Ivins' help, according to the documents, and the scientist offered agents his notebooks, his office, and his email.

He passed a polygraph in connection with the investigation in 2002, but investigators learned years later that he had been prescribed psychotropic medications at the time. Examiners who reassessed the results concluded that Ivins exhibited classic signs of the use of countermeasures to pass a polygraph.

The new documents also present a novel theory why the anthrax notes featured block writing that highlighted specific letters within words.

Investigators believe Ivins' use of the letters was part of a secret code that had two possible meanings: pointing to a colleague, or stating a specific dislike of New York. Two of the letters were sent to New York - one to The New York Post, and another to NBC television's then-anchor Tom Brokaw.

The anthrax case was one of the most vexing and costly investigations in U.S. history. Officials announced in 2008 that the lone suspect was Ivins. The move Friday seals that preliminary investigative conclusion.

Laced with anthrax, the letters were sent with childish, blocky handwriting and chilling scientific expertise.

The spores killed five people: Two postal workers in Washington, a New York City hospital worker, a Florida photo editor and a 94-year-old Connecticut woman who had no known contact with any of the poisoned letters. Seventeen other people were sickened.

For years, the FBI chased leads but filed no charges.

In 2008, the agency announced that the mystery had been solved but the suspect was dead.

Authorities said that in the days before the mailings, Ivins had logged unusual hours alone in his lab at the Army Medical Research Institute of Infectious Diseases at Fort Detrick, Md. They also said he threw investigators off his trail by supplying false leads as he ostensibly tried to help them find the killer.

As the FBI closed in on Ivins, the 62-year-old microbiologist took a fatal overdose of Tylenol, dying on July 29, 2008. After Ivins' suicide, FBI Director Robert Mueller said the investigation found he was the culprit, and prosecutors said they were confident he acted alone.

Skeptics - including prominent lawmakers - pointed to the bureau's long, misguided pursuit of Hatfill, and noted there was no evidence suggesting Ivins was ever in New Jersey when the letters were mailed there.

At the urging of lawmakers, the National Academy of Sciences has launched a formal review of the FBI's scientific methods in tracing the particular strain of anthrax used in the mailings to samples Ivins had at his Fort Detrick lab.
