Editing Aaron Alexis (section)

==Shooting==
Sometime before 8:20 a.m. on September 16, Alexis arrived at the Navy Yard in a rental car, using a valid pass to enter the Yard. He entered Building 197 carrying the disassembled shotgun (the barrel and stock of which had been sawed off) in a bag on his shoulder. He assembled the shotgun inside a bathroom on the fourth floor, then emerged with the gun and began shooting. Many of the people shot on the fourth floor were shot at close range in the head.

He then continued firing on the third floor and the lobby. At some point, Alexis shot and killed a security officer and took the officer's Beretta 9mm semiautomatic pistol, using it after running out of ammunition for his shotgun. Initial reports that Alexis claimed most of his victims by firing from a fourth-floor walkway onto people entering a first-floor cafeteria were later stated to be incorrect.

At 8:23 a.m., the first calls to 9-1-1 were made. Six minutes later, a four-person active-shooter response team was deployed into the building. Around that time, Alexis was still firing shots on both the third and fourth floors.

A NAVSEA employee described encountering a gunman wearing all-blue clothing in a third-floor hallway, saying, "He just turned and started firing." At one point during the shooting, one man was hit by a "stray bullet" in an alleyway.

As D.C. police responded within seven minutes of the first shootings, Alexis opened fire on them, hitting an officer, Scott Williams, in the leg. He engaged several law enforcement personnel in a gunfight that lasted for more than 30 minutes. At around 9:20 a.m., Alexis was fatally shot in the head by police on the third floor; his death was later confirmed at 11:50 a.m.

===Victims===

There were 13 fatalities. The suspect and 11 of the victims were killed at the scene, while a 12th victim who was shot in the head, 61-year-old Vishnu Pandit, died at George Washington University Hospital. All the victims killed were civilian employees or contractors. Eight others were injured, three of them from gunfire. The survivors wounded by gunshots (police officer Scott Williams and two female civilians) were in critical condition at Washington Hospital Center.
