acoustic 'attacks' with some kind of device that emitted directional

ultrasonic or higher frequency sound beams or energy, such as radio
frequency microwaves. Some personnel appear to have suffered severe
vestibular, auditory, and cognitive symptoms, in addition to other ailments.
While these events appear to have begun in Havana in late 2016, similar

events have periodically been reported around the world . In approximately
May 2018, the FBI also began investigating similar reported events withCYREB

To date , however, this case has not determined orfound any evidence that a weapon or some type of alternative device was used to target these 'victims' or others.

This case has not yet determined if a foreign actor (s) or unknown offender(s ) was responsible for targeting or

injuring these 'victims' or others. The broader medical community and actual medical personnel treating these'victims' and others have still not determined the cause for the health conditions experienced by so many.

Based upon information available at the time this report was prepared , our analysis indicates several of
the 'victims' in these cases may have experienced an episode of Mass Psychogenic Illness or social contagion
andInstead , many of the individuals considered to be ' victims'

may have experienced fairly common symptoms due to predetermined medical conditions or other conditions that
could have originated from anything, including the environment.

We can't provethese environmental cause theories, but we can't disprove them either.
