WASHINGTON (AP) — The man who gunned down 12 people at the Washington Navy Yard on Monday visited two hospitals in the weeks before the rampage but denied that he was depressed or having thoughts of harming himself or others, the Department of Veterans Affairs said Wednesday.

Aaron Alexis, a former Navy reservist 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.
