Okwu: Piecing the anthrax puzzle

OXFORD, Connecticut (CNN) -- Investigators painstakingly reconstructing the last weeks of a Connecticut widow's life waited Friday for results on tests conducted in her home and nearby postal facilities, hopeful that those results could clarify how Ottilie Lundgren contracted a fatal case of inhalation anthrax.

CNN's Michael Okwu is following the story in Oxford. He filed this report.

OKWU: Police blocked off access to Ottilie Lundgren's remote house here in a wooded section of Oxford, as investigators conducted a grid search or an inch-by-inch inspection of her home. Results of tests taken from her house are expected in the next 24 hours. Investigators are also taking a close look around the neighborhood, specifically at the beauty salon and the church that she frequented.

Results of an autopsy are not yet known. Examiners are taking special interest in her air passages. Investigators still believe that Lundgren was the possible victim of cross-contamination in the mail. A mail distribution center in Wallingford, Connecticut, and a postal facility in Seymour, Connecticut, not too far from here, were tested Wednesday and those results are expected today.

In the meantime, postal officials have given some 1,200 workers at both those facilities the option of starting a 10-day course of Cipro, and we are told a majority of them have. In the meantime, a very interesting note -- on the answering machine of the postal carrier who specifically distributed mail to Lundgren, there is a message to callers in which he offers his condolence to Lundgren and her family and says that he himself is feeling fine and is taking Cipro.
