Article about murders

I just read the article by Jacquielynn Floyd about an interesting murder. I find it interesting how you can completely misjudge something by going off of prevous knowledge. I feel like people get caught in a pattern of how things normally are or by what movies tell them. I feel that somehow we always blame the victim and never the killer. Its always well if the victim hadnt done that they would still be alive or the victim is stupid for talking to that person. Never, oh the killer was just a psycho. The victim isnt alive to defend themselves, therefore its very annoying when blame is put on.
