Oh, red, I'm so sorry. I'm always sorry to hear of yet another incident. I hope she manages to heal, I hope he goes away for a good, long time.
The only comfort we can take is that with an incident like this, none of the defenses that are typically trotted out are likely to persuade a jury. Chances are that he will get bail (in most jurisdictions, only murder is non-bailable), but hopefully it will be too high for him to post. I hope he goes away for a VERY long time. (Our organization works against prison rape, so I won't hope for that--the culture that permits it to occur results in the victimization of people who have never committed a crime of violence and it should never happen in our correctional institutions.)
Will keep her, and her family, in my thoughts and prayers. Sadly, this happens every day. Sadly, even worse things happen in DV settings. Many of them never see the light of day in the media.
