Actually, there are reports that he spent a lot of time alone in his room playing a specific game but I don’t know the name. And the first thing my college age son said when he saw the name is that it was a gamer tag.
Apparently there are websites for these games and you take a name and add Ax on the end. And these are games so if he was heading out to kill, he might have wanted to keep the persona on.
He was probably gone more often than he was here. I just figured he had classes.Doesn't sound like "a lot of time alone in his room." They also said that he spent "a lot of his time" on the computer "downloading music and stuff" (not gaming). But what do they know? They only live there.
And his gamer persona "just happened to be" the name of an high Islamic Prophet and spelled using the Islamic spelling?
