Someone else posted on another thread a republican judge threw out case because she medically couldn't move and she wanted somewhere closer to her. They then claimed the below:

she refused to appear for an independent medical examination despite warnings that failure to do so would result in the case’s dismissal.

So in context sounds like they got him off on technicalities. I dont know much else so hopefully someone else fill more.

and the family has said she had a variety of mental health issues

She was raped by her brother. Use your head.
