I just saw the show about this tradgedy. I want to convey my thoughts and prayers with the family. I ended up in tears.  
It reminded me of how my sister was 'stalked' by the town 'wacko' recently and the police dept. told her, unless she dated him, she couldn't do anything, no restraining order, no report, etc.. She knew him by seeing him in town and saying hello, he took this as some sort of 'come on'. He started to threaten her online. The policeman told her, maybe u should go out with him once, I said what? to kill her?! then they said maybe she should have 'someone' talk to him. She said, 'so someone has to call u to tell u this jerk killed me is what your telling me, when u can do something?' The police officer said, 'yes, basically'. And she's an adult. I was so upset, I'm in another state, that I went onto her the town website (which was my hometown) and told them how I felt. The next day I got a call from the Capt. of the police dept. I then told him what happened and we had it straightened out and she filed a report and spoke to the Capt. and his Lt. and spoke with them of what can be done which was more than the other officers told her. They were not only surprised at what I told them their officers said, but wanted the officers name to straighten 'him' out. But my thoughts were the same of, 'what will he do next?' 
But seeing this show, only outrages me to think that if you have money, you can get out, no matter what. They should definately work on the law change. How many people have to be killed, or tortured before something is done?! Like most things, so many people have to die before anything is done. I pray that no more lives are taken because of this law. One child lost is one too many. 
Caitlin and her family are in my prayers.
