WASHINGTON (AP) - Investigators have been focusing on the erratic behavior of a former Navy reservist who law enforcement officials say was grappling with paranoia and had reported hearing voices and being followed before he gunned down 12 people at the Washington Navy Yard this week.
The Department of Veterans Affairs said Wednesday that 34-year-old Aaron Alexis visited two hospitals in the weeks before the Monday morning rampage but denied that he was depressed or having thoughts of harming himself or others.
Alexis, who died in a police shootout after the rampage, complained of insomnia during an Aug. 23 emergency room visit to the VA Medical Center in Providence, R.I. He was given sleep medication and advised to follow up with a doctor. He made a similar visit five days later to the VA hospital in Washington, when he again complained of not being able to sleep because of his work schedule. His medication was refilled.
Alexis appeared "alert and oriented" during the visits and denied feeling depressed or anxious or wanting to do harm, the VA said in a statement presented to lawmakers Wednesday.
Two weeks before his ER visit, for instance, he complained to police in Rhode Island that people were talking to him through the walls and ceilings of his hotel room and sending microwave vibrations into his body to deprive him of sleep. Navy officials said the Newport police reported the incident to officers at the base security office, but nothing more was done about it because he did not appear to be a threat to himself or anyone else at the time.
Despite the apparent concerns over his mental health and past run-ins with the law, Alexis maintained his security clearance as he arrived in Washington in late August for a job as an information technology employee at a defense-related computer company.
Alexis had been a full-time Navy reservist from 2007 to early 2011, and a Navy spokesman said his security clearance, at the "secret level," was good for 10 years from when he got it.
On Monday morning, he used a valid badge to gain access to the sprawling Navy Yard and Building 197, bringing with him a sawed-off shotgun on which the cryptic messages of "better off this way" and "my ELF weapon" were scrawled, according to a law enforcement document reviewed by The Associated Press. The meaning of those words wasn't immediately clear.
The motive of the shooting also remains unclear, though investigators have focused on Alexis's mental health and alarming behavior displayed in the weeks before the massacre.
Alexis had enrolled in VA health care in February 2011, and received monthly disability payments of $395 for orthopedic problems and ringing in his ears, according to the VA. He never sought an appointment from a mental health specialist and either canceled or failed to show up for primary care appointments he had scheduled at VA hospitals, the department said.
Meanwhile, Alexis's mother said Wednesday she does not know why her son opened fire on office workers and police. Cathleen Alexis read a brief statement inside her New York home, her voice shaking. She did not take questions from a reporter.
