Any help will help

My mother in law and sister were dropped home in a taxi on Friday night 13/09/13 from town to Nutgrove and they left a camera in the taxi, it's not the camera but my father in law retired and his son missed the speech so I recorded it on the camera, we REALLY want the memory card, the camera can be replaced, they said their driver was a lovely man from India, I know it's a long shot but its worth a try
