Probably rape
They called him a sex offender so some type of sexual abuse. Most likely rape but the woman also knows how to fight so we don't know entirely.
It does not matter if she can fight bc he was stronger then her you could tell when they where training
I'm aware of that but if someone does know how to fight they can still damage someone who is stronger than them. For enough time for them to escape, but if someone's stronger than you you're chances of winning a 1v1 fight without playing tricks is slim.
So she could have hit a pressure point or poke him in the eye.
What did he do to her that made him a criminal I didnt get that part
