Federal investigators said they're done with their searches of the anthrax-tainted former home of The National Enquirer.
The feds have been scouring the building for 12 days in search of clues in last year's anthrax attack. They've provided few details.
Anthrax fatally infected photo editor Robert Stevens last fall.
Investigators have been searching for the letter or package that brought anthrax into the building, which is owned by tabloid publisher American Media Incorporated.
