It might have to do with the possibility of this not being a lone individual....different news outlets keep reporting on another person arrested. They had the place locked down for over 5 hours, and put a lot of effort into searching the neighborhood, long after "the perp" was dead.
That makes me even more nervous! I have been reading lately that there are “Columbine Fan Clubs” on the internet, where admirers of those two evil ones discuss and plan like incidents. The boy who shot up the school in Sweden belonged to one of these, and was in discussions with the boy from PA. who was caught before his plans panned out.
Very very scary.
It was reported on the local news here in Colorado Springs that the gunman’s body is still inside the church where it was dropped and that they haven’t approached it yet because it may be rigged with a device.
