'Delusional' Navy Yard gunman fired at random targets
THE Washington Navy Yard gunman did not target specific individuals when he opened fire inside a building, killing 12 people, and was under a delusional belief that he was being controlled by extremely low frequency electromagnetic waves, the FBI have said.
Records recovered from Aaron Alexis's computer and cellphone reveal paranoia and mental health problems.
"Ultra-low frequency attack is what I've been subject to for the last three months, and to be perfectly honest that is what has driven me to this," read a document agents recovered.
He had also written "my ELF weapon" – an apparent reference to extremely low frequency waves – on a shotgun he used in the rampage.
Alexis, a 34-year-old former Navy reservist and IT contractor, used a valid badge to access the Navy Yard with a shotgun that he had purchased two days earlier.
He was killed by a park police officer following a rampage that lasted for about an hour.
Authorities say Alexis had only recently started his job, and that although there was a "routine performance-related issue addressed to him" on the Friday before the shooting, there's no indication that he targeted particular co-workers.
"There is no indication that this caused any sort of reaction from him. We have not determined there to be any previous relationship between Alexis and any of the victims," said Valerie Parlave, head of the FBI's Washington field office.
At the Pentagon, deputy secretary Ash Carter said the department will complete three reviews in late December.
"Bottom line is, we need to know how an employee was able to bring a weapon and ammunition onto a DoD installation."
