The mother of Washington Navy Yard gunman Aaron Alexis apologized to the victims on Wednesday, and like his friends and colleagues she was unable to offer clues on his motive for the shooting.
“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 never do harm to anyone, and for that I am glad,” Cathleen Alexis said in an audio statement aired on MSNBC from her home in New York. “To the families of the victims, I am so, so very sorry that this has happened. My heart is broken.”
All 12 victims, aged 46 to 73, were civilians caught up in the shooting spree on Monday morning by the former Navy reservist who was working as an information technology contractor at the military installation.
Alexis was killed in a gun battle with police officers.
As investigators tried to find out what set off Alexis, 34, U.S. Defense Secretary Chuck Hagel acknowledged there were “red flags” before Alexis received security clearance to work at the complex despite having a history of misconduct and mental health problems.
“Obviously when you go back in hindsight and look at all this, there were some red flags - of course there were,” Hagel told a news conference. “And should we have picked them up? Why didn't we? How could we have? All those questions need to be answered.”
Alexis had secret-level security clearance and entered the military installation with a valid pass.
Outside of Washington, coffee chain Starbucks Corp. asked U.S. customers to leave their guns at home after being dragged into an increasingly fractious debate over gun rights. In a letter and a video presentation, Chief Executive Howard Schultz said the request was not a ban and not in response to the Navy Yard shooting, but nonetheless called it a “timely message.”
The massacre, just a mile and a half (2.5 km) from the U.S. Capitol and three miles (five km) from the White House, was the latest in a series of shooting rampages that have shocked the United States in recent years and reopened debate about gun laws.
Bought Shotgun in Virginia
Alexis, who was a resident of Fort Worth, Texas, legally bought the 12-gauge Remington shotgun used in the rampage for $419 at the Sharpshooters Indoor Shooting Range and Pro Shop in Lorton, Virginia on Saturday, the store's lawyer, J. Michael Slocum said on Wednesday.
Slocum said the store refused to sell Alexis a handgun.
“He asked about buying a handgun but was told, no he couldn't buy a handgun because he's not a Virginia resident. At that point, he bought the shotgun,” Slocum said.
He said Alexis rented an AR-15 assault rifle and fired it at a store shooting range, and then bought the shotgun along with two boxes of ammunition. According to store employees, he did not ask to buy an AR-15, Slocum said.
Alexis brought a shotgun into the Naval Sea Systems Command building and grabbed at least one handgun once inside, investigators said, opening fire from the fourth floor atrium on helpless victims in a cafeteria below.
Investigators have a “working theory” that Alexis arrived at the building with the shotgun barrel removed, entered a men's room with his bag or backpack, and assembled it, according to a source close to the investigation.
The shooting was the worst at a military facility since 2009 when 13 people were killed and 31 wounded at Fort Hood, Texas, by an army psychiatrist who later said he carried out the shootings because of U.S. wars in Muslim countries.
Alexis had been arrested twice, once in 2004 and again in 2010, for illegally discharging firearms, though in each case charges were not pursued.
Police in Newport, Rhode Island, had warned the U.S. Navy last month that Alexis had called them to report “hearing voices” while in Newport on business, behavior odd enough that police sent a copy of the report to Navy officials.
The Navy said it was looking into the Rhode Island incident.
