The KGB's surveillance system was widely recognized as the elite of the elite, and all male CIA officers stationed in Moscow were under constant KGB surveillance and unable to meet safely.
The CIA's counterintelligence department believed that the KGB would not use women to carry out high-risk operations, so it sent Marty Peterson as the breakthrough.
The CIA equipped Peterson with an SR-100 receiver to intercept radio communications between KGB surveillance teams in order to determine whether she was being followed.
The SR-100 receiver exploited the weakness that KGB surveillance teams used specific frequency bands for voice communications, determining whether she was being followed by listening to the communications.
In July 1977, Marty Peterson was arrested by the KGB in Moscow, but thanks to diplomatic immunity she was released after several hours of interrogation.
Trigon bit into the poison ampoule and died when the KGB broke down his door, a week before Peterson saw the van in the park.
What led to Trigon's exposure was CIA translator Karl Kocher, who secretly worked for Czech intelligence and passed information back to the KGB through Czech intelligence.
