What is your question?
If you ask me, this is horrible. Rape is just about as low as you can get then then murdering is even worse. I think we should all stand up against human trafficking. Its my parsonal goal in life to rescue as much people as possible from this situation. Sort of going of topic, just thought I should mention that.
