Isn't that the truth? Simple suicide under a large investigation by the FBI according to the OK Homeland Security on Channel 9 tonight. Just move on, nothing to see here.
It is odd to me that dad asserted he thought of his son as a good boy; it implies that others might think he was not. In other words, father has been told by authorities that his son might have been involved with terrorists and they are investigating (how do you tell a father that his son blew himself up using a suicide vest and not ask father whether son was involved with Muslim terrorists?). If the son had committed suicide in a more traditional way, the father wouldn't need to defend his son's goodness, IMO.
