I too get chills every time I hear or read something about this horrible story. As Markpj23 has surely found it hits pretty hard for those who knew anybody involved with this. I share this uncomfortable familiarity with him, just the other way around. I hope my bringing this up isn't inappropriate or anything, but I think it's worth saying.
Through a friend-of-a-friend-of-a-friend type scenario, I was introduced to and for a short time was loosely acquainted with the husband & wife who perpetrated this crime. I met them right around the time they were getting married, and seemed like just about anybody else I'd ever met. Perhaps they struck me as products of Southern California's weak educational system and questionable social atmosphere, but around here lots of people their age are like that. I didn't know them well, but would never have guessed either of them were capable of something like this.
The death of the Hawks was a tragedy without rival, but the loss did not end there. While not enough prayers could possibly be said for the victims, I hope there are still some left out there for the other people out there whose lives were shattered by this. Two
children lost their mother and father, mothers and fathers
lost their own children. Lifelong friends realized that they didn't really know them at all, and while the loss of friends like those may actually be a net gain, it's still a little bit unsettling to know that you've had Bonnie & Clyde over to your pad for a cocktail party.
And if your faith or whatever else may be permits you even a little forgiveness toward all the people who made this happen, I think they'll need everything they can get.
