The FBI is investigating the apparent removal of classified information from the Los Alamos National Laboratory in New Mexico, birthplace of the first atomic bombs detonated in wartime. The secret material was found during a drug bust at a trailer park.
The documents have been traced to a woman who had worked at the lab. The FBI is investigating the woman, who has been identified as "a former subcontractor employee" — likely an archivist, one official said.
Some of documents are in electronic form, raising questions about the labs ability to keep track of digital secrets.
The facility has had trouble with classified material before. In 2000, two classified computer hard drives disappeared. After a long search, they were discovered behind a copy machine.
In 2004, two more classified computer disks could not be found. The lab later concluded they had never existed, calling them figments of sloppy record-keeping. But parts of the lab were shut down for 7 months.
Los Alamos is now managed by the University of California and three other contractors. The federally funded facility has a budget of more than $2 billion and more than 10,000 employees.
