WASHINGTON - Hunting spies is difficult, but Cuban spies are notoriously hard to detect, former senior intelligence officials said a day after an American husband and wife were indicted on charges of spying for Cuba.
Walter Kendall Myers and his wife Gwendolyn of Washington were arrested Thursday after a three-year investigation that began before Myers' retirement from the State Department in 2007. They had been spying for Havana for 30 years, according to the U.S. government.
Investigations like this typically take years to come together because they usually turn on small pieces of information, and Cuban spies often leave few traces. Cuban intelligence specializes in recruiting "true believers" rather than agents who are out to make money, these officials said. They spoke on condition of anonymity because the investigation is ongoing.
