Awful story. It sounds like the son went bad; the article mentions that he had two children (but no mention of a wife) and was arrested for possession of drug paraphrenalia, so I'd imagine he had probably been a family problem for awhile. Very tragic, and I always really feel for families that have a problem like this with one member. They sounded like lovely people, I will pray for them and their community when I go to Mass today.
I was thinking about this story as I lit the morning fire. What on earth got into this young man ?
