I'm so confused.

they come in all varieties.

...like many believe Sirham Sirloin was.

Wierd.

They killed people they knew. He took the life of people he worked with every day. Jesus! People who gave them a baby shower! How could he look anyone he knew in the eye and murder them in cold blood? People who had no way to defend themselves.

If he had shown he hated them, or had been a victim of a layoff or firing it could make some sort of demented sense, but no such reason was there.

This is as disturbing as it gets.

Religious extremists don't think normally.

...where coworkers told interviewers that people at work were known to have made fun of his beard. Between the beard bullies and the "Messianic Jew," it sounds like he perceived his workplace to be somewhat hostile.

TYY

Really? Someone made fun of his beard?

I find that hard to even believe, but then everything about this murder is hard to believe.

...planning a bigger massacre elsewhere, but angry, retaliatory emotions drove him to go after his coworkers first. I think they had every intention of getting away with it to strike somewhere else later, but his personal feelings screwed up the bigger picture. Attacking people he knew was his downfall and thankfully so.

TYY

them was that he was teased for his beard. It did not sound like a big deal, especially in light of the fact that other men in the office had beards, as well.

From what I can determine, he was hired when he was beardless, and then started growing out his beard as he became more radical.
My husband was teased when he tried to grow a beard, so I don't think that's such a great tragedy.

because of his beard.

Yet other men in the office also had beards, so how awful was this teasing?

Listening to the co-workers, they are shocked because they believed they had a good relationship with him.

"That" is what is scary.
