York University chef Claudia Lawerence went missing nearly three years ago. Security cameras showed Claudia leaving York University campus at 2.30pm on 18th March 2009. She was picked up by another camera as she posted a letter on the way home. Police know she was alive and well and probably at home in the evening when she made phone calls to both her parents. However, she didn't turn up for her 6 o'clock shift at the university the next morning.
