my friend was kicked out from her sisters house where she was living and her sister refused to give her belongings back. We have evidence that her sister has those things and that those things are my friends. My friend at first was pursuing criminal charges against her sister but didnt want her arrested at the time she was picked up by police because her sister had a child with her. The detective says nothing can be done about it and she wont get her things back or be able to press charges. This has caused an immense amount of mental damage and hurt. What can be done about it?
