The FBI opened up today about its investigation thus far into the Sept. 16 Navy Yard shooting, releasing video of Aaron Alexis entering the premises, assembling his shotgun and starting his deadly spree.
Investigators said interviews and searches have yielded evidence that allowed them to piece together what happened before the 34-year-old killed 12 and was shot by police on the third floor of building #197.
From the FBI:
Alexis was employed as a contractor for a private information technology firm. Pursuant to his employment, Alexis was assigned to a project at the Washington Navy Yard and he arrived in the Washington, D.C., area on August 25, 2013. From August 25 to August 31, 2013, Alexis stayed at a hotel in Bethesda, Maryland. From August 31 to September 7, 2013, Alexis stayed at a hotel in the Pentagon City area of Arlington, Virginia. On September 7, Alexis moved to the Residence Inn in Southwest Washington, D.C., where he remained through September 16, 2013. Alexis began working at the Washington Navy Yard on September 9, 2013.
On Saturday, September 14, 2013, Alexis purchased a Remington 870 shotgun and ammunition at a gun shop in Northern Virginia. On the same day, Alexis also purchased a hacksaw, among other items, at a home improvement store in Northern Virginia.
On the morning of Monday, September 16, 2013, Alexis arrived at the Washington Navy Yard. Alexis had legitimate access to the Navy Yard as a result of his work as a contractor and he utilized a valid pass to gain entry to Building #197. Shortly after his arrival in the building and over the course of approximately one hour, Alexis used the Remington 870 shotgun and a Beretta handgun he obtained during the course of his shooting to kill 12 victims and wound four surviving victims before he was shot and killed by law enforcement officers. Investigation to date has determined that Alexis acted alone.
Alexis arrived at a Navy Yard parking garage at 7:53 a.m., and shot the first victim at 8:16 a.m. He was killed at 9:25 a.m.
Both weapons used by Alexis were recovered at the scene and have been submitted to the FBI Laboratory for forensic analysis. The Remington 870 shotgun had been altered with a sawed-off barrel and stock. Purple duct tape covered the end of the stock and handwritten etchings were present on various parts of the shotgun. 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’ backpack was located in the fourth floor men’s bathroom, hanging on the back of a stall door. Contents of the backpack included a roll of purple duct tape and electronic media. Searches were conducted of Alexis’ blue Toyota Prius rental car, located in Parking Garage #28, and his hotel room in Southwest Washington, D.C. Additional electronic media was located in the hotel room.
Analysis of the electronic media recovered from Alexis’ belongings revealed several relevant communications. While analysis of these communications is ongoing in conjunction with other information and evidence determined through investigation, preliminary analysis has yielded clues to his intentions and issues of importance to him. There are indicators that Alexis was prepared to die during the attack and that he accepted death as the inevitable consequence of his actions. There is no indication to date that Alexis was targeting specific individuals.
