WASHINGTON — The mother of Aaron Alexis said Wednesday that she does not know why her son opened fire at the Washington Navy Yard, killing 12 people, but she is glad he can no longer hurt anyone else.
Cathleen Alexis read a brief statement Wednesday inside her New York home, her voice shaking. She did not want to appear on camera and did not take questions from a reporter.
“I don’t know why he did what he did and I’ll never be able to ask him why. Aaron is now in a place where he can no longer do harm to anyone, and for that I am glad,” Cathleen Alexis said. “To the families of the victims, I am so so very sorry that this has happened. My heart is broken.”
Although his motive remains unknown, law enforcement officials and others have described a paranoid man who heard voices and believed he was being followed. At a Rhode Island hotel recently, he heard voices harassing him, wanting to harm him. He couldn’t sleep. He believed people were following him, using a microwave machine to send vibrations to his body. He changed hotels once, then again. But he called police and told them he couldn’t get away from the voices.
On Aug. 7, police alerted officials at the Newport Naval Station about the naval defense contractor’s call. But officers didn’t hear from him again.
By Aug. 25, Alexis had left the state. The 34-year-old arrived in the Washington area, continuing his work as an information technology employee for a defense-related computer company. Again, he spent nights in different hotels. He suffered from serious mental problems, including paranoia and a sleep disorder, and was undergoing treatment from the Department of Veterans Affairs, according to the law enforcement officials.
But Alexis wasn’t stripped of his security clearance, and he kept working.
On Saturday, he visited Sharpshooters Small Arms Range in Lorton, Va., about 18 miles southwest of the nation’s capital. He rented an AR-15 rifle, bought bullets and took target practice at the 16-lane indoor range. He tried to buy a handgun, but federal law prevented him from doing so because he had an out-of-state ID, the store’s attorney said. He then bought a shotgun and 24 shells. The law allows stores to sell shotguns and rifles to out-of-state buyers.
Two days later, as the workweek dawned, Alexis entered the sprawling Washington Navy Yard, a 41-acre labyrinth of buildings protected by armed guards and metal detectors where employees must show IDs to get past doors and gates. Authorities believe he drove a rental car there.
He was equipped with his pass for base access — and the shotgun. Within minutes, it would create mayhem.
He stepped inside the massive Building 197, home to some 3,000 employees. He opened fire around 8:15 a.m., raining shotgun blasts down from a fourth-floor overlook and third-floor hallway into a glass-walled cafeteria where employees were eating breakfast. Trained tactical officers arrived, bursting through the building within seven minutes of the first 911 call, and Alexis shot at them, too.
Fire alarms blared, and officers had a hard time hearing one another. A voice came on the overhead speaker telling workers to seek shelter — and later, to head for the gates at the complex. A U.S. Park Police helicopter flew overhead, plucking a wounded woman from the roof with a rescue basket while a crew member armed with a rifle provided cover.
“We have a report on the fourth floor, a male with a shotgun, multiple shots fired, multiple people down. We’re still waiting for the OK that the scene has been secured,” an ambulance crew member says on emergency transmissions posted on Broadcastify.com, a source of live public safety audio feeds.
More dispatches followed: Shooter known to be in the main gate area. Officer down on the third floor. Female on the roof, shot in the shoulder.
Once inside, Alexis picked a handgun off an officer and, armed with two weapons, terrorized the building’s occupants.
He fired relentlessly not only at police who engaged him but at the workers inside: a 61-year-old marine engineer and grandfather who immigrated to the U.S. years ago from India, a Navy veteran and avid pilot who had once been stationed at Pearl Harbor, a die-hard Washington Redskins fan known for generous bear hugs. A Washington police officer was shot multiple times in the legs but survived.
“We just started running,” said Patricia Ward, who was in the cafeteria when the shooting began. She said she heard three gunshots in a row, followed by several more.
Descriptions from witnesses and police paint a portrait of harrowing gun battles inside — all for more than half an hour. The FBI, which launched a nationwide active shooter training program for local law enforcement after last December’s Connecticut elementary school massacre, says the average mass shooting is over within minutes and often ends once police arrive.
But this gun battle kept going. As the chaos unraveled inside, police in the nation’s capital shut down the surrounding area. Nearby schools went on lockdown, flights were halted at Reagan National Airport, and even after Alexis was mortally wounded by a police officer, officers chased leads that a second and possibly a third gunman had been working with him.
Twelve victims died — a body count that police say could have been much higher, even after they determined that the gunman had worked alone. Eight were injured, with all expected to survive.
The Navy said several garages and all surface parking lots at the Washington Navy Yard would open Wednesday for employees to retrieve their private vehicles. But the military installation would reopen for business for Mission Essential personnel only. In a posting on its Facebook page, the Navy said the yard remains an active crime scene.
Meanwhile, Defense Secretary Chuck Hagel ordered the Pentagon to review the physical security of all U.S. defense facilities worldwide and the security clearances that allow access to them. Hagel is also tasking an independent panel to undertake the same reviews. He said Wednesday “where there are gaps, we will close them.”
More than 24 hours after the shooting, the motive remained a mystery. U.S. law enforcement officials told The Associated Press that investigators had found no manifesto or other writings suggesting a political or religious motivation.
Ron Machen, the U.S. Attorney for the District of Columbia, ticked off some of the unanswered questions Tuesday.
“What caused this individual to kill so many innocent men and women? How did he carry out and plan this attack? How did he get access to the weapons? What could have been done to prevent this tragedy? And most importantly, whether anyone else aided or assisted him either wittingly or unwittingly in this tragedy?”
Machen added, “We’re not going to stop until we get answers to those questions.”
