I think she refused to give him her PIN number (or gave him a wrong PIN) to the debit card. I recall most of the wounds were to her right side, which would make sense if she remained sitting in the back passenger seat. I doubt she ever stepped out of that car alive. Absolutely breaks my heart.ITA, I think poor Sami assumed it was her Uber, got in on her own, and he took the opportunity to rob her. I believe she put up quite a struggle and that might have been why he was so angered in the stabbing.
