Video: Washington Navy Yard Shooting: Friends and relatives speak of 'nice guy' gunman The family of Washington DC Navy Yard gunman Aaron Alexis stayed behind closed doors in their home in Brooklyn, New York as Aaron's brother-in-law, Anthony Little, briefly spoke to reporters outside the family home. "He wasn't that type of person," Little said of Alexis. I didn't hear anything that would make me feel like, as a newcomer to the family, that somebody should be watching him... Nobody ever mentioned anything about him being aggressive or being this type of way or anything like that. A neighbour who admitted he hadn't seen Alexis for years said he never saw anything that disturbed him. Calvin Belton described Alexis to the Associated Press. Pretty nice guy, didn't say anything much. Just sort of said hello and kept moving. Alexis, a 34-year-old information technology employee and former Navy reservist, died after a gunbattle with Washington, DC police on Monday. He had gone on a deadly shooting rampage inside the Washington Navy Yard, killing 12 people. It was the deadliest shooting on a military installation in the US since the shooting at Fort Hood, Texas in 2009.
