Why... Oh why... Kill her? I'm sick thinking about it!
Personally I think it was a rage killing and he panicked. I understand why he would try to protect himself. But his friend Chris, his sister, mother, and even his BIL can join him in prison for allowing themselves being dragged into his mess. The lawyer I am not impressed with either, some crazy comment about Robert. I know she should do her best to give him a defense, but her comment makes me think less of her.
