As the nation mourns the innocent victims of Monday's Navy Yard shooting, family and friends of the shooter reevaluate the man they thought they knew.
"I would never have believed this until it happened," said friend Michael Ritrovato.
"Aaron was a very polite, very friendly man," said another friend Kristi Kinard Suthamtewakul.
But with the image of 34-year-old Aaron Alexis now staring out from screens and newspaper covers worldwide, glimpses of his contradictory character are coming into full view.
A friend of Navy Yard shooter Aaron Alexis said his heart goes out to all the innocent victims of Monday's shooting rampage.
"I just never would have seen anything like this coming with Aaron. He didn't seem like that kind of a person," said Michael Ritrovato.
"We would have never guessed that Aaron would be capable of pointing a gun and actually shooting a person, let alone many people," said Ritrovato. "It's a really hard thing to handle because he was like a friend, a family friend, a brother to me, and so I don't understand what set him off."
Police in Rhode Island contacted the Newport Naval station in August to warn them about an encounter they had with one of their contractors – Aaron Alexis, the man responsible for Monday's shooting rampage at the Navy Yard in Washington, D.C.
