Either she was moved or she was just let go, them feeling the danger was over. Who knows?
If she met the police in the building, why didn't the police go upstairs and arrest Hardy on the spot, if that was the story she was spinning. Why would they let a potential woman beater have the freedom to just turn himself in, when they had the victim in their custody and they were that close?
A lot of the story doesn't make sense to me. Honestly.. I'm in the camp of believing, if he beat her, she would have much more damage than just a few minor bruises and minor scrapes.. which is what some are saying she had? That kind of stuff makes me think that she was being restrained and she was struggling.
