60 Minutes producers Michael Rey and Oriana Zill de Granados say their five-year investigation into “Havana Syndrome” evolved from embassy complaints in Cuba in 2016 into a global probe of more than 1,000 reported incidents. Their reporting followed victims from Cuba to China and the U.S., tracked scientific theories about possible causes, and — they say — turned up what one source called “a receipt” suggesting acoustic or directed-energy testing by a Russian intelligence unit.
What investigators and victims reported
– Early cases involved embassy and consulate staff who described sudden intense symptoms: headaches, pressure in the temples, dizziness, balance and walking problems, memory loss and cognitive difficulties. Victims sometimes heard an unusual sound first — loud and persistent in some accounts.
– Mark Lenzi, a State Department security officer who worked in Guangzhou, China, described being hit repeatedly and believed he was targeted because of his work analyzing electronic threats to diplomatic missions.
– Robyn Garfield, a Commerce Department official, reported attacks to his family in China and later suspected a second incident in the U.S. He described hearing a “distinct sound” near his children’s heads and seeing them thrash while asleep.
Scientific and technical theories
– Some researchers and engineers have proposed high-power microwaves or radio-frequency (RF) energy in the microwave range as plausible mechanisms. Physicist James Benford noted that microwaves can penetrate glass and were developed in many countries, including the U.S., Russia and China.
– Victims and some scientists argue the pattern and severity of symptoms align with directed-energy exposure. Others, including parts of the intelligence community, say the incidents have multiple causes and lack clear, consistent physical evidence linking them to a single mechanism or foreign state.
Intelligence community assessments
– In 2021 the CIA released an interim assessment that did not find evidence of a worldwide campaign by a foreign adversary to harm Americans. The director of national intelligence later said it is “very unlikely a foreign adversary is responsible.” CIA Director William Burns and other officials have said the intelligence community has not been able to connect the dots or identify a single cause for all reported incidents.
– The producers say their reporting has surfaced material that challenges that public assessment.
What the 60 Minutes reporting says it found
– Investigative journalist Christo Grozev located an email that Rey and de Granados describe as containing a “receipt” for work done by a Russian unit known as 29155. They say the message documents empirical tests of a directed-energy or acoustic device by members of that unit.
– The producers called this “the closest to a receipt you can have” linking a Russian intelligence unit to testing of a directed-energy capability. They emphasize that their role is to publish what sources provided and to ask questions of U.S. agencies whose public statements have downplayed a foreign-adversary explanation.
Context and reactions
– The investigation spans five years and includes interviews with affected diplomats, agency officials, independent scientists and investigative specialists. It documents the frustration of victims who say their symptoms were dismissed or misattributed and their difficulty obtaining care or recognition.
– Officials in the U.S. intelligence community maintain that no conclusive evidence links a state actor to the full set of incidents and that the pattern is complex, with multiple possible causes. The producers counter that their reporting — including the newly cited document tied to a Russian unit — raises significant questions about that public conclusion.
The producers’ perspective
– Michael Rey and Oriana Zill de Granados say their job is to report what sources have provided and to challenge official narratives when evidence suggests otherwise. They describe the investigation as an effort to assemble cases, technical analysis and documents that could point to responsible actors or technologies — and to press U.S. agencies to explain what they have and what they have concluded.
This reporting joins a broader public and scientific debate over the cause or causes of Havana Syndrome, the appropriate response to affected people, and whether foreign intelligence services have developed or tested directed-energy or other unconventional capabilities against U.S. personnel.
