The FBI released a video Wednesday showing footage of deceased gunman Aaron Alexis, 34, at the Washington Navy Yard on Sept. 16. Alexis used a Remington 870 shotgun and a Beretta handgun to kill 12 victims and wound four before he was shot and killed by law enforcement officers. 

Both weapons used by Alexis were recovered at the scene and have been submitted for forensic analysis, according to the FBI. 

Through evidence gathered, the FBI has also released the following timeline detailing Alexis’ alleged activity during the morning of his deadly rampage. 

There are multiple indicators that Alexis held a delusional belief that he was being controlled or influenced by extremely low frequency (ELF) electromagnetic waves.

The FBI wrote in a press release: 

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.'

The FBI's investigation indicates that Alexis acted alone. To read more details about his activities on Sept. 16, you can read the full press release here
