In 1985 Col. Vladimir M. Piguzov, codenamed GT/JOGGER by the Central Intelligence Agency, a KGB officer recruited in Djakarta and assigned to the KGB’s Andropov Institute training academy, dropped from sight. This was an especially mysterious and sinister loss, for Piguzov had not been in contact with the CIA since 1979 when he had returned to Moscow and had proven himself to be an exceptionally useful source by identifying David Barnett, a turncoat CIA retiree working on a training program on contract who was arrested in April 1980 and had been sentenced to 18 years’ imprisonment.
