Ep 975: Secret Service Investigator Reexamines Princess Diana's Death
SHOW NOTES What Really Happened to Princess Diana? Investigator Rich Staropoli Examines the Evidence Nearly three decades after Princess Diana's death, questions and theories surrounding the fatal Paris crash continue to fascinate people around the world. In this episode of The Sisterhood of S.W.E.A.T., Linda Mitchell sits down with former U.S. Secret Service Special Agent Rich Staropoli, one of the investigators featured in FOX's new special, Celebrity Crime Scene: Princess Diana. Staropoli spent approximately 25 years with the U.S. Secret Service, holding supervisory positions within the New York Field Office, Presidential Protective Division, Counter Assault Teams, and Secret Service headquarters. He has conducted approximately 500 polygraph examinations and managed the Protective Intelligence Division in New York following 9/11. In 2016, he was nominated by President Donald Trump to become the first presidentially appointed Chief Information Officer for the Department of Homeland Security. Now, he brings that investigative and protective-security experience to one of history's most scrutinized tragedies. Linda and Rich discuss how professional investigators separate evidence from speculation, what a virtual reconstruction can reveal about the crash, the questions that have fueled decades of theories, and how someone trained to protect high-profile individuals evaluates the events surrounding Diana's final night. They also dive into human behavior, deception, protective intelligence, threat assessment, and what Rich believes viewers should pay attention to when they watch the special.
