Well either the door was locked/closed or it wasn't. She didn't break it down. So it was unlocked/ajar or he opened it. If he answered the door she would have realized it wasn't her apartment. So it was ajar like she claims or he opened it. She had no reason to shoot him unless she knew him and was angry or something. Toxicology will be interesting. Not every relationship is known to neighbors, friends or family. If I was her and I shot a guy who jilted or dumped me or cheated on me in a fit of rage -- I might want to claim it was a simple case of misunderstanding/wrong address. Her story likely won't hold up -- unless by some weird chance it is true.
