He planned to walk after blowing up his room and the car. Why all the explosives,bulletproof vest and breathing device. The master explosion was the fuel tanks. This was going to be huge. It would be nice to know his firing sequence. People or fuel tanks .
You can tell the motive by looking at the people he killed. Who were they? It wasn’t a teachers convention.

Yes that is an important clue/fact.
The other big clue is the 23 guns. He could never shoot but a handful of them, so why so many?
He was either expecting help or he was trying to make a statement about guns.
