Ronald Montaperto

Ronald N. Montaperto is a former Defense Intelligence Agency analyst who admitted to leaking classified defense information to China.

Montaperto, 66, joined the DIA in 1981 and eight years later sought a post at the CIA that eventually led to suspicions he was a spy for China. An investigation of his links to Chinese intelligence in 1991 was dropped for lack of evidence. During questioning by investigators in Hawaii in 2003, where he was dean of the Asia-Pacific Center for Security Studies, Montaperto said he verbally gave Col. Yang and Col. Yu both "secret" and "top secret" information.
