Maybe he had porn on the computer. Hey, maybe he was surreptitiously filming his mother, and had pictures of her on his computer.
One day, she finds out, gets really mad, and smashes his computer. He retaliates by grabbing one of her guns, and killing her. Then he runs to the elementary school and kills a bunch of kids before taking his own life.
Or maybe he took his computer with him to the school, but when he drove through the bermuda road triangle, his computer was sucked out of that reality and back to his house, where it was dropped in his room, smashing the hard drive.
How do you smash just a hard drive, without first taking it out of your computer?
He was a geek, I’m quite sure he was capable of removing a hard drive. We don’t know the extent of the smashing either.
All I know is that real life takes longer than television.
If he smashed up his computer(s) then he had a reason for it and if the investigators get lucky, they might find out what it was and maybe it might shed some light into his sorry mess of a mind. But it might be completely trivial, petty and inexplicable to the normal instead of a smoking gun.
Just reading these threads, it’s obvious that there are a lot of people on the edge of the crazy cliff and they fixate and obsess on the darnedest things.
