During his time as an Army lieutenant colonel, Greg Edgreen led the Pentagon investigation into what officials are calling "anomalous health incidents." Edgreen revealed that the high standard of proof required for these incidents is due to the country's reluctance to confront difficult truths, such as potential failures in protecting Americans.

Edgreen mentioned, "Unfortunately I can't provide details due to classification. However, I can say that early on in the investigation, my attention turned towards Moscow."

A 2023 government report deemed it "very unlikely" that a foreign adversary was behind the mysterious brain injuries suffered by U.S. national security officials, yet more than 100 Americans have symptoms scientists say could be caused by a beam of microwaves or acoustic ultrasound. Victims are frustrated that the government publicly doubts an adversary is targeting Americans. The ongoing, five-year 60 Minutes investigation has now uncovered new evidence pointing toward Russia.

Are we being attacked?

White House staff, CIA officers, FBI agents, and military officers and their families are among those who believe they were wounded by a secret weapon firing a high-energy beam of microwaves or ultrasound. 

Edgreen said the officers targeted were top performers. 

"And consistently there was a Russia nexus," he said. "There was some angle where they had worked against Russia, focused on Russia, and done extremely well."

"It tells me that there are no barriers on what Moscow will do, on who they will attack, and that if we don't face this head on, the problem is going to get worse," Edgreen said.

60 Minutes has agreed to withhold the last name of "Carrie," a Havana Syndrome victim who is still an FBI agent working in counterintelligence. Her case also points to Russia. 

She said she was home in Florida in 2021 when she was hit by a crippling force.

"And suddenly, deep inside my right ear, it felt like a dentist drilling with superhuman strength. That sensation of nearing your eardrum? Multiply that by 10," she recounted.

Simultaneously, she described how the battery in her phone started swelling until it cracked the case. Eventually, she collapsed on a couch. Experiencing chest pain, she underwent a check-up by a cardiologist and then resumed her duties. Over the following months, she repeatedly raised concerns with her colleagues about memory lapses and difficulties with multitasking.

"My core self transformed," she expressed. "I was no longer the same individual."

She shared her story with the FBI's authorization but was restricted from discussing the cases she was handling at the time of the incident. 60 Minutes, through various sources, discovered that one of the cases involved Russian Vitalii Kovalev, who was apprehended for speeding in a Ford Mustang near Key West, Florida, in 2020. Following a high-speed pursuit, a search of the vehicle uncovered notes related to bank accounts, as well as a device capable of wiping the car's electronic data, including GPS records. Additionally, a Russian passport was found.

The Probe into Kovalev

Insights from 60 Minutes and investigative partner Christo Grozev, a journalist at The Insider, a publication by Russian expatriates, indicate that Kovalev may have been a Russian operative.

Former military institute student, Kovalev, surprised many when he abruptly switched careers to become a chef in New York and Washington, according to renowned investigator Grozev. Grozev highlighted the challenge of leaving behind military training, suggesting that individuals remain tied to the Ministry of Defense indefinitely.

Despite spending 80 hours being interviewed by "Carrie," who has a history of investigating Russian spies for the FBI, Kovalev's activities remain shrouded in mystery. Following a 30-month jail sentence in the U.S., Kovalev returned to Russia in 2022, disregarding warnings of potential danger due to his extensive interactions with the FBI. Grozev's findings revealed a recent death certificate indicating Kovalev's demise on the Ukrainian front.

One speculation is that Kovalev was strategically placed in Ukraine for disposal, as suggested by Grozev.

Attorney Mark Zaid, representing "Carrie," disclosed that over two dozen clients, including CIA, State Department, and FBI personnel, are experiencing symptoms related to Havana Syndrome.

"The one thread that I know of with the FBI personnel that is common among most, if not all, of my clients other than the family members connected to the employee, was they were all doing something relating to Russia," Zaid said.

Russian intelligence unit 29155

If it is Russia, Grozev believes Russian intelligence unit 29155 is involved. Grozev has a long track record of uncovering Russian documents and reveals he found one that may link the 29155 unit to a directed energy weapon.

It's a piece of accounting. A 29155 officer received a bonus for work on "potential capabilities of non-lethal acoustic weapons..."

"It's the closest to a receipt you can have for this," Grozev said.

Sources have told 60 Minutes that an investigation centered on Russian Albert Averyanov, whose name appears on travel manifests and phone records alongside known members of 29155. He's also the son of the unit's commander. 

Incidents began in Tbilisi the day after a phone call, which was intercepted. Sources said a man on the call asked in Russian: "Is it supposed to have blinking green lights?" and "should I leave it on all night?"

Unsolved Mystery in Tbilisi

Recent events in Tbilisi have left residents on edge, with a series of mysterious attacks targeting U.S. officials and their families. The wife of a Justice Department official, who spoke to "60 Minutes" on the condition of anonymity, described a terrifying experience in her own home.

On October 7, 2021, she was startled by a piercing sound in her laundry room, followed by intense pain and vomiting. Reviewing security footage, she noticed a suspicious vehicle and a man lurking nearby. A photo of a suspect, Averyanov, was shown to her, triggering a strong emotional response.

Investigator Grozev uncovered that Averyanov's phone was inactive during the incidents, but there was activity on his personal email account from Tbilisi. This has raised suspicions that Averyanov himself may have been present in the city at the time of the attacks.

Has there been a cover-up?

According to Zaid, who is representing over two dozen clients affected by anomalous health incidents, he suspects that the U.S. intelligence assessment does not reveal the full story. Zaid claims to be aware of classified information that challenges or contradicts the public narrative.

"I am certain that there has been a cover-up. However, this cover-up may not necessarily be about the discovery of a weapon," Zaid explained. "What I have observed is a reluctance to pursue certain lines of investigation that could lead to uncomfortable truths, resulting in a deliberate avoidance of exploring those possibilities."

As with all spy stories, much is classified and what remains is circumstantial. None of the witnesses 60 Minutes spoke with wanted to come forward, but they all felt compelled to shine a light on what they see as a war of shadows — a war America may not be winning.

"If this is what we've seen with the hundreds of cases of anomalous health incidents, I can assure that this has become probably Putin's biggest victory," Grozev said. "In his own mind this has been Russia's biggest victory against the West."

Statements from the Office of the Director of National Intelligence, the White House, and the FBI

In response to inquiries from 60 Minutes, the Office of the Director of National Intelligence referred to the Intelligence Community's Annual Threat Assessment commentary on anomalous health incidents. The assessment was released earlier this month and states:

When asked by 60 Minutes, a representative from the White House replied:

When questioned by 60 Minutes, a spokesperson from the FBI replied:
