Anthrax mystery deepens

WASHINGTON — A letter to Sen. Patrick Leahy was laced with billions of anthrax spores, authorities said Tuesday, and a suspected case of the most deadly form of the disease mysteriously appeared in Connecticut.

An elderly woman who lives in the farm country of southwestern Connecticut tested positive for inhalation anthrax, the first suspected case in several weeks. Kathy Johnson, the first selectman of Oxford, identified her as 94-year-old Ottillie Lundgren.

Lundgren was hospitalized in critical condition as authorities awaited additional test results from the federal government.

"It’s difficult to explain how the person contracted anthrax," Connecticut Gov. John Rowland said. "There is no evidence (she) contracted the disease as a result of a criminal act."

Lundgren tested positive for the inhaled form of the disease in five separate tests conducted by the Department of Public Health and Griffin Hospital in Derby, Conn., the governor said.

More tests were being conducted by experts at the Centers for Disease Control and Prevention in Atlanta. Results were expected today. "Testing by the CDC could prove negative," Rowland said.

He said Lundgren lives in Oxford, a rural community about 30 miles southwest of Hartford. She originally was treated for pneumonia and admitted Friday to Griffin Hospital. The next-day tests pointed to anthrax.

In Washington, D.C., trace amounts of anthrax were found in the mailrooms of two congressional offices and FBI agents and scientists began their analysis of the Leahy letter found last week.

An FBI microbiologist, speaking on condition of anonymity, said there were easily billions of anthrax spores in the letter. Scientists have said 8,000 to 10,000 spores are enough to infect a person with inhalation anthrax.

An investigator who found the Leahy letter in unopened congressional mail last Friday could feel powder inside the envelope, the microbiologist said. A two-minute test of the garbage bag that held the Leahy letter detected 23,000 anthrax spores, he said.

The FBI and the Environmental Protection Agency spent nearly a week searching about 630 trash bags containing sequestered Capitol Hill mail before they found the Leahy letter. Investigators cut a hole in each bag and tested it for signs of anthrax. About 50 of the bags had at least trace amounts of anthrax spores.

The Leahy letter was similar to one sent last month to Senate Majority Leader Tom Daschle. Both envelopes were postmarked Oct. 9 from Trenton, N.J., had the same fictitious "Greendale School" return address and were written in all-capital block letters.

Postal Inspector Dan Mihalko said the Leahy letter never got to the senator’s office because it was quarantined along with all other Senate mail after the discovery of the Daschle letter.

Mihalko said there is an "extremely high probability" that the Leahy letter was misrouted on Oct. 12 to a State Department mail facility in Sterling, Va., where a worker came down with inhalation anthrax.

The offices of Sens. Edward Kennedy, D-Mass., and Christopher Dodd, D-Conn., were closed early after trace amounts of the bacteria were detected in their mailrooms. Officials said the samples were so minute they did not pose a health risk, but the offices would be cleaned over the weekend.
