This is the last article in a week's worth of information after an odd young man scribbled a bomb threat on the bathroom wall. This is about the 10th article on the incident and the only one with the word 'rocket propellant' in it. They could have used it all week, so IMO they did very well.
This kid has to go back to Canada, if you do "bomb search' on phillyburbs.com you'll see he was selling homemade napalm in junior high. I would suggest he be gulaged above the artic circle.
