According to court records, Conrad was introduced to the Hungarian secret service in 1975 by his supervisor in the 8th Infantry Division, former U.S. Army Sergeant First Class Zoltan Szabo.
Szabo, who was convicted of espionage in Austria in 1989, received a 10-month suspended sentence in exchange for assisting in the investigation by identifying some of the documents Conrad sold to the Hungarians.
Ramsay alleged to the FBI that Conrad had recruited dozens of personnel, including at least one member of the Army's counter-espionage branch, and at least one officer who later became a general.
Conrad was arrested in 1988 by West German authorities and tried for high treason and espionage on behalf of the Hungarian and Czechoslovakian intelligence services.
Conrad's treason had doomed the Federal Republic to become a nuclear battlefield.Conrad died of a heart attack at the age of 50 in Diez prison on January 8, 1998.
