We don't know yet. But I am also very interested in this. She apparently knew him, though some are denying it, himself included. But I can't believe she would have met him there at that time if they didn't know each other. And the Lyft driver said she seemed relaxed and excited to see him. Maybe you're right, they texted and he offered to let her stay in his vacant AirBnB room, no charge, so she wouldn't have to go back to her place and roommates. Just a ruse to get her there. But somehow he got her phone turned off immediately. Did he attack her as soon as the Lyft car was out of sight, or did he con her into turning it off or giving it to him? Probably never know.
