Hey check under the car seats,glove box ,in seat cushions etc ....? I have lost things in car before and found weeks later. I doubt she would of left that camera. She prolly left with it and just didnt relize where she put it. You just dont forget 700 bucks. Maybe if she was that "hammered" she might of loaned it to a drinking buddy and just forgotabout doing so. Ask the friends if they remember her with the camera also ask the bartender he might of saved and put up in lost and found type of thing.....Oh one more thing if she got sick from drinking check behind the toliet you never know.
