The FBI is draining a city pond in Frederick, Maryland, apparently looking for clues to how the deadly, anthrax-laced letters mailed in 2001 were assembled.
Some investigators have said the latest probe is related to the FBI's interest in Steven Hatfill, who used to work at an Army lab in Frederick. Federal officials had described him as a "person of interest."
Hatfill's spokesman Pat Clawson says there are flaws in a reported FBI theory that the letters were assembled in an underwater device. He also says Hatfill doesn't know anything about the pond.
But Clawson says if draining ponds can further establish Hatfill's innocence, then as far as he's concerned, the FBI can drain the Pacific Ocean.
An FB statement says simply that agents are doing searches to find "items of evidence" related to the anthrax attacks. It says one pond is being drained.
