You are very stubborn, nor do you pay attention, Nine. You are right, however, about Coroner Paul Forrest, who lost his case in the High Court against Bristol. There is a can of worms there, in full public view. During his suspension, Maria E. Voisin was acting as the Coroner for Avon & Somerset. Hers is the name on Joanna's death certificate. Her deputy assistant coroner was Terry Moore, who also rated a mention in connection with the release of the body.
Dr. Hugh White's CV,which you yourself found, describes him as a forensic pathologist. He gave evidence in several other grisly cases that were quoted in the news media and can be found online. He is not on the Home Office's register of pathologists, and therefore has to include on his CV that he does work for coroners.
Why leave the contents of the stomach in situ for 23 days? Presumably while Anne Reddrop negotiated with Dr White, Jennifer Miller and other hands-on professionals about keeping them out of the hands of the defence pathologist. It was important to make public that Joanna had not eaten the pizza just before Vincent Tabak was arrested. The crying girl had nothing to do with this.
