Russell O'Brien and Jane Tanner
A university friend of David Payne's, Russell O'Brien is also a doctor, who worked in Leicester. He and Ms Tanner have two children, the older one the same age as Madeleine. This daughter, the newspaper Sol reported yesterday, was vomiting on the night the toddler disappeared, so Ms Tanner spent much of the evening away from the dinner table. She is a key witness on the night of the disappearance, having told police that around 9.20pm she saw a man walking away from the McCanns' apartment carrying a child.
