Russian Spy Chef and the Mystery of Havana Syndrome

Vitalii Kovalev, a former executive chef at prestigious Russian-themed restaurants, was arrested in Florida in 2020 and revealed to be an undercover technical officer for the GRU, Russia's military intelligence service. FBI agents who interviewed him suffered from symptoms of Havana Syndrome, possibly caused by a directed energy weapon. Kovalev spent time in jail, declined to confess to being a Russian agent, and later died under mysterious circumstances near the Ukraine border.
