I find this case quite interesting. It reminds me quite a lot of the Martin Bryant case at Port Arthur. Both seemed to be similar characters with similar backgrounds.
He actually ended up killing himself inside a local college. Fortunately it was the summer holidays so there wasn't anyone around.
I believe his last words were something along the lines of 'Hungerford must be a bit of a mess, I should have just stayed in bed' then blew his brains out.
