(CNN) – The hardest question about Newtown, and the one we have the fewest answers to right now, is the shortest one: “why?”
Not much is known right now about the shooter, Adam Lanza, and what motivated him to kill.
Alan Diaz, 20, is one of the few who knew him. He hadn’t seen Lanza since high school. Back then he would have called him a friend.
Today, he struggles with his past connection to Lanza.
[2:06] “I never imagined him committing an act of violence against anyone, so when I heard that he went into that school and took 26 lives I really just couldn’t comprehend it.”
[1:32] “We all kinda knew that like you know, he had problems socially and we had a feeling that there might have been something wrong with him but obviously we never asked, we never thought it was our place to do so.”
[4:18] “At one point he was a good kid, the events of that day may have been evil, but before that he was a good kid.”
