As law enforcement continues its investigation into the mass shooting at the Washington Navy Yard on September 16, the Federal Bureau of Investigation shared what is has learned so far, including releasing new video surveillance and photos of gunman Aaron Alexis from the morning of the shooting.
Officials in the Defense Department, according to Fox News, are infuriated the FBI “unnecessarily” and “gratuitously” published the video footage that shows Alexis arriving at and entering building 197, where he is then seen methodically making his way through the corridors.
The following is a timeline of Alexis’ actions Monday, September 16, 2013:
7:53 a.m. – Alexis’ rental car, a blue Toyota Prius with New York plates, entered Parking Garage #28 at the Washington Navy Yard, located directly across from Building #197.
8:08 a.m. – Alexis exited Parking Garage #28 on foot carrying a backpack. Alexis entered Building #197 and proceeded to the elevator.
8:09 a.m. – Alexis exited the elevator on the fourth floor and entered the men’s bathroom carrying a backpack and a clipboard.
8:15 a.m. – Alexis crossed the hallway into the 4 West area of Building #197 with shotgun, but without the backpack or a clipboard.
8:16 a.m. – Alexis shot the first victim in the 4 West area of Building #197.
8:17 a.m. – First 911 call is received from the fourth floor of Building #197.
8:20 a.m. – Alexis left the fourth floor using the stairs and entered the third floor.
8:28 a.m. – Alexis appeared on the first floor.
8:57 a.m. – Alexis returned to the third floor.
9:25 a.m. – Law enforcement shoot and kill Alexis on the third floor.
Alexis, 34, entered the Navy Yard that Monday with a valid pass he obtained when he began work as a civilian contractor on September 9 with a sawed-off Remington 870 shotgun he purchased in Virginia on Saturday, September 14.
“On the same day [he purchased the shotgun], Alexis also purchased a hacksaw, among other items, at a home improvement store in Northern Virginia,” the FBI reported Wednesday.
Once inside the building, Alexis obtained a Beretta handgun he used along with the shotgun to kill 12 people and wound others before being killed himself by police.
Previous reports have detailed the severe mental problems Alexis suffered, and through electronic media and other communications left by Alexis, the FBI learned “Alexis held a delusional belief that he was being controlled or influenced by extremely low frequency (ELF) electromagnetic waves.”
According to the FBI report published on its website:
The etching of “My ELF weapon!” on the left side of the receiver of the Remington 870 shotgun is believed to reference these electromagnetic waves. In addition, a document retrieved from his electronic media stated, “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.”
ELF technology was a legitimate program for naval sub-tonal submarine communications; however, conspiracy theories exist which misinterpret its application as the weaponization of remote neural frequencies for government monitoring and manipulation of unsuspecting citizens.
Alexis, who the FBI determined acted alone, “was prepared to die during the attack and that he accepted death as the inevitable consequence of his actions,” the report said.
