*Aaron Alexis was ready to die and believed he was being controlled by extremely low-frequency electromagnetic waves when he shot and killed 12 people during his attack on Washington Navy Yard earlier this month, FBI officials said at a press conference Wednesday.
The Bureau released a series of photos and a video from the Washington Navy Yard that show Alexis preparing to carry out the attack. [Watch below.]
Alexis is not believed to have been targeting any specific individuals, and apparently did not know any of his victims, Valerie Parlav, assistant director in charge of the FBI’s Washington Field Office, said at the press conference.
Alexis carved “End to the torment!” “Not what yall say!” and “Better off this way!” on the weapon he used.
