Aaron Alexis had complained to police that he was being targeted by disruptive mind control technologies:
Washington Navy Yard gunman Aaron Alexis left a note saying he was driven to kill by months of bombardment with extremely low-frequency radio waves, the FBI said Wednesday in a disclosure that explains the phrase he etched on his shotgun: “My ELF Weapon!”
Alexis did not target particular individuals during the Sept. 16 attack in which he killed 12 people, and there is no indication the shooting stemmed from any workplace dispute, said Valerie Parlave, assistant director in charge of the FBI’s Washington field office. Instead, authorities said, his behavior in the weeks before the shooting and evidence recovered from his hotel room, backpack and other belongings reveal a man increasingly in the throes of paranoia and delusions.
“Ultra-low frequency attack is what I’ve been subject to for the last 3 months, and to be perfectly honest that is what has driven me to this,” read an electronic document agents recovered after the shooting.
The attack came one month after Alexis had complained to police in Rhode Island that people were talking to him through the walls and ceilings of his hotel room and sending microwave vibrations into his body to deprive him of sleep.
