Or possibly he was in as much pain as her family is. Imagine having an argument with the woman that you loved and planned to marry, that ends up in her death--at your own hands? I am not of the opinion that he planned to end her life, and if he did accidentally kill her, I could see that he would not be any happier with himself than anyone else is. It would be an unbearable pain. If he has been found, and they determine suicide as COD, I think everyone has all the answers they need. Those close to Gabby have a lot more insight as to what was going on with Brian and Gabby in the weeks before her death, and I'm sure they either are being given ,or will be given, information from the FBI investigation to fill in the cracks
