It's desperately sad.
It made me think of another case. Sarah and Amina, they were teenage sisters in the USA.
Their father was horrendous. He sexaully abused them. The father was egyptian. He wouldn't let them have American boyfriends.
He found out that Amina had a boyfriend and the threatened to kill her. The mother ran away with the two girls to another state . But the dad persuaded the mother to come back. He told the mother that the boyfriend was forgotten about and he wanted to move on as a family.
They came back. He brought his two daughters out in a car and shot them both dead.
Her boyfriend was in the documentary and he showed letters amina had written to him.
The letters said "my dad Is going to kill me. I know he will. When he kills me , I want you not to be upset your whole life, I want you to be happy"
I cried for days after watching it.
