Pollard later agreed to a search of his home, which found the few documents which Anne had missed. At this point, the FBI decided to cede the case to Pollard's supervisors, since they had uncovered only mishandling of documents, with no proof that Pollard was passing classified information. The case broke wide open a few days later, when Pollard was asked by his superiors to take a polygraph test. Instead, he admitted to illegally passing on documents, without mentioning Israel. The FBI again became involved. A short time later, Pollard's neighbor, a naval officer, became concerned about safeguarding the suitcase full of highly classified material that Anne had given him, and began calling around the military intelligence community asking for advice. He cooperated fully with the investigation and was never charged with any crime.
