She could have "hidden" somewhere in the house and waited for dark in order to walk/jog to her rental car parked down the block. If she was completely finished up with the murder at 6:00 PM (ish), she would only have to wait an hour until dark (maybe even less, because June is the monsoon season out here and it could have been rainy and dark that day), thus being dark by 6:30 or so....(JMO). So she would not have had to wait long to sneak OUT of the house. Again, this may have already been covered in the trial or on these threads, and I apologize if that is so, I haven't been reading here much lately, but I sure enjoy everyone's ideas and opinions!
Very interesting! I thought it was super-weird or shall I say conspicuous (sp.?) that she kept saying the sun was in her eyes as she was driving when she left his house. She said it multiple times on the stand. THEREFORE, you are right she is lying and she definately waited until dark. That was just a line she came up with.
