A troubled Army bio-weapons scientist was the only person responsible for the 2001 anthrax attacks that killed five people and injured 17 others, the Department of Justice said today.
At a news conference and in hundreds of pages of court documents unsealed today, investigators said they zeroed in on Bruce Ivins, who committed suicide last week, after learning that he had custody of a batch of anthrax that had "genetic mutations" identical to the type used in the attacks.
Ivins allegedly also sent an e-mail warning that terrorists had access to anthrax, using language similar to that found in handwritten notes sent to media and government officials along with anthrax spores, just a few days before the antrhax letters were sent, according to the documents
After a seven-year investigation, which focused for much of the time on the wrong suspect, the Department of Justice today declared the case solved. After presenting a largely circumstantial case against Ivins, U.S. Attorney Jeffrey Taylor said he was confident that Ivins was the only person responsible for the attacks, adding, "We regret that we will not have the opportunity to present evidence to the jury."
Taylor said that a scientific breakthrough in 2005 allowed investigators to trace the anthrax used in the attacks to a single flask of anthrax that was under Ivins' custody at an Army lab in Fort Detrick, Md. Investigators focused on Ivins as the main suspect in 2007, after eliminating nearly 100 others who had access to the flask as possible suspects, he said.
Lawyers for Ivins lashed out at the government's case, saying the evidence is thin and that Ivins was a respected scientist.
"The government released search warrants – investigative tools designed to discover evidence, not to serve as evidence and treated these warrants as smoking guns," lawyers from Venable LLP said in a statement. "The government's press conference was an orchestrated dance of carefully worded statements, heaps of innuendo and a staggering lack of real evidence – all contorted to create the illusion of guilt by Dr. Ivins."
But the documents unsealed today say Ivins struggled with depression and paranoia for years, and became increasingly troubled as investigators closed in.
Affidavits also say the FBI suspected that Ivins gave the bureau false anthrax samples to mislead investigators and was "unable to give investigators an adequate explanation for his late-night laboratory work" around the time the anthrax letters were sent, according to the documents.
Ivins sent an e-mail to a recipient whose name was redacted a few days before the anthrax attacks, warning that Osama bin Laden and other terrorists "for sure have anthrax."
Thomas Dellafera, an investigator for the U.S. Postal Inspection Service, which conducted the probe with the FBI, said Ivins wrote in the e-mail that the terrorists have "just decreed death to all Jews and all Americans."
That language, investigators claim, was similar to that of the anthrax letters, which warned, "WE HAVE THIS ANTHRAX ... DEATH TO AMERICA ... DEATH TO ISRAEL."
Investigators also reportedly traced the envelopes used to mail the anthrax spores to the Fort Detrick, Md., post office.
The government's presentation of its case came as the U.S. Army Medical Research Institute of Infectious Diseases held a memorial service for Ivins, which was attended by family and co-workers.
