Video: Navy Yard Shooter Wielded Sawed-Off Shotgun

VIDEO: FBI's Navy Yard Shooter Footage

The FBI has released preliminary findings of the Sept. 16 Washington Navy Yard shooting that includes new details about the shooter's weapons, a timeline of his movements, and his mental state leading up to the shooting.

The release includes video surveillance footage showing Aaron Alexis, 34, entering the complex and stalking the hallways with a sawed-off Remington 870 shotgun and Beretta handgun he used as a lone-wolf gunman to kill 12 people and wound four others.

Alexis modified the shotgun he purchased at a northern Virginia gun shop two days before the shooting by sawing off the barrel and stock. He also added etchings indicating his mental illness, according to the FBI.

"Purple duct tape covered the end of the stock and handwritten etchings were present on various parts of the shotgun," according to the FBI release. "Etched into the barrel of the shotgun were the words 'End to the torment!' Etched into the right side of the shotgun receiver were the words 'Not what yall say!' and etched into the left side of the receiver were the phrases 'Better off this way!' and 'My ELF weapon!'"

Alexis, who was employed as a contractor for a private information technology firm, apparently believed he was "being controlled or influenced by extremely low frequency (ELF) electromagnetic waves," according to the FBI.

"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," the FBI said. "In addition, a document retrieved from his electronic media stated, '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.'

Alexis arrived in the Washington D.C. area on Aug. 25 to begin work at the Navy Yard earlier this month, according to the FBI timeline. From Aug. 25-31, he stayed at a hotel in Bethesda, Md. From Aug. 31-Sept. 7, he stayed at a hotel in Arlington, Va. On Sept. 7, he moved to the Residence Inn in southwest Washington. He began working at the Navy Yard two days later.

On Sept. 14, Alexis purchased the shotgun and ammunition. The same day, he purchased a hacksaw and other items at a home improvement store in northern Virginia.

Alexis arrived at the Navy Yard on the morning of Sept. 16 and used a valid pass to gain entry to Building 197. At one point during the rampage he obtained a Beretta handgun. He was shot and killed by responding Metro (D.C.) Police officers.

When he first arrived, Alexis drove a rented blue Toyota Prius into a parking garage across from Building 197 at 7:53 a.m. He entered Building 197 at 8:08 a.m. carrying a backpack and headed to the elevator. At 8:09 a.m., Alexis exited the elevator on the fourth floor and entered the men's bathroom carrying the backpack and a clipboard. At 8:15 a.m., Alexis crossed the hallway into the 4 West area of Building 197 carrying only the shotgun. He shot the first victim at 8:16 a.m. At 8:17 a.m., police received the first 9-1-1 call. At 8:20 a.m., Alexis left the fourth floor using stairs and entered the third floor. At 8:28 a.m., he appeared on the first floor. At 8:57 a.m., he returned to the third floor. At 9:25 a.m., police officers end the rampage by shooting and killing Alexis on the third floor.

Alexis was prepared to die in the attack and there are no indicators he was targeting specific people.

ELF technology was a legitimate program for naval sub-tonal submarine communications; however, conspiracy theories exist that misinterpret its application as the weaponization of remote neural frequencies for government monitoring and manipulation of unsuspecting citizens, according to the FBI.

The media so wanted the weapon to be an ar15.

This is obviously is an 870, but it does not appear to be sawed-off. SOMEBODY's LYING TO US...

Jeff Thompson @ 9/26/2013 12:49 AM

Think they maybe referring to the "Butt" being sawed off? I have a 870 and the barrel on this appears to be a bit shorter? @ Troop yeah they did. so did "O" but they still managed to plant the idea that day it was a AR 15 then a AR 15 Shotgun! Idiots

Once they recovered that it wasn't an AR-15 (or even worse, not a white guy belonging to the NRA but a racist black who killed 84% non-blacks) the shotgun was labled "a police/military weapon". I'm surprised these same bad actors (Obama so wanted to roll in the blood of the victims in his speech while the attacks were still "warm") didn't want to disarm the police since the officer's pistol was used to shoot people. "If only police didn't carry guns and be like Bobbies in England, how many people wouldn't be shot every year!" Don't think our would-be masters wouldn't enjoy that idea.

If people modify their weapons after they buy them, how is gun control gonna stop them. IT AINT

Ima Leprechaun @ 9/27/2013 6:44 AM

I find it comforting that not one of the 20 or so cameras at the Navy yard is monitored by a human being. If they were police would have been called before he shot one person. But legally he never committed a capitol crime until he pulled the trigger as the gun nuts will tell you, he had every right to buy and own any gun he wanted. As for the ELF radio waves that controlled him. They control everybody not just him but the rest of us don't go off the deep end. We are all under the control of sercret government radio waves like it or not.

Lets Roll,

The shotgun looks like it has a two shot magazine extension on it. And the barrel looks like it is essentially the same length as the extension. Typically, even with an 18" barrel, the barrel extends an inch and a half or so beyond the magazine extension. So it appears to me that this barrel has been cut off to some degree. Of course, we don't know if he purchased it with an 18" barrel or a 28" barrel, he may have cut off a little or a lot. But it looks to me like it has been cut off. The article clearly claims that he sawed off the barrel and the stock.
