I think that's best Melody. In a way, by knocking on their door you are saving his life and that of others and they should appreciate that. If it's the "block" like I lived on, in Chicago, I understand your concern over calling the cops. Just do what is in the best interest of the community by telling his wife and family.

BTW, what happened on 9/11 to them? Did they lose a family member or was it just too close for comfort? I remember how affected we were here in the Chicago area so I can only imagine how bad it seemed being so close to it. I had a firefighter friend who worked at the scene and he was never the same.
