I like to think this juxtaposition was intentional.
This horrible thing happened. The final paragraph of the article:
Henderson said Gilkey had been showing signs of instability but that he thought any violent behavior on Gilkey's part would be self-inflicted and only after his wife had passed away from her terminal cancer. Gilkey had already served 10 years in prison for beating a man to death with a fence post in 1974 and in 1986 allegedly stabbed his own father.
I can't help reading that last sentence as having an unspoken you stupid fuck appended to it.
