More Personnel Added to Anthrax Investigation

The largest team of investigators since the FBI began checking for anthrax at the former headquarters of the National Enquirer descended on American Media Inc.’s offices, beginning a 12-hour shift, police officer Jeff Kelly said.

Officials wouldn’t say how many people were in the Boca Raton building or if any evidence had been found since crews in protective gear reentered the building Friday for the first time since last fall’s contamination. The investigation will continue until Sept. 11.

The teams hope to find a letter or package that carried the anthrax bacteria into the building and fatally infected photo editor Bob Stevens. FBI investigators also want to compare anthrax spores with spores found in letters sent to the Washington offices of Sens. Patrick J. Leahy of Vermont and Tom Daschle of South Dakota.
