WASHINGTON (AP) -- Investigators are 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.
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 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.
