243: Peter Lapp – Ana Montes Espionage Case, FISA Warrants

Retired agent Peter Lapp served in the FBI for 22-years. Assigned to the Washington Field Office, he specialized in counterintelligence, espionage, economic espionage, and trade secret theft matters.

In this episode of FBI Retired Case File Review, Pete reviews the espionage investigation of Ana Belen Montes, who was arrested ten days after 9/11 for espionage, and sentenced to 25 years for spying for the Cuban Intelligence Service while she worked at the Defense Intelligence Agency.

The application of Foreign Intelligence Surveillance Act (FISA) warrants played a key role in Pete and his senior co-case agent’s ability to gather evidence in this case.

Pete was also the case agent on the theft of trade secrets investigation of MIN Yonggang, who as a former DuPont employee was convicted of misappropriating over $1 billion of the company’s trade secrets. Pete gained inter-agency experience while conducting a joint-duty assignment at the Office of the Director of National Intelligence/Partner Engagement. Later in his career, he was promoted to program manager, and chief of the economic espionage and People’s Republic of China (PRC) espionage units at FBIHQ’s Counterintelligence Division.

Pete conducted hundreds of awareness briefings while at the Washington Field Office to academic, industry, and community groups on the topics of counterintelligence, insider threat, and active shooter.

Pete is the founder of PJ Lapp Consulting, LLC where he now focuses his vast knowledge and experience in counterintelligence and insider risk. He is a widely recognized expert and thought leader in the area of IR. Combining his experience as an investigator and program manager of espionage and economic espionage investigations, Pete is well qualified to provide seasoned advice on how to successfully build your IR program to mitigate reputational risk and protect your critical assets to help companies maintain their competitive advantage.

    You can watch the CNN ” Declassified ” series which has Ana Montez searching with firestick. I don’t think it’s free , but we’ll worth watching.
    There are several different stories with scumbags who betrayed their country.
