And no dog picke dup a scent of a cadaver. The british dog handler wrote a report stating no evidence was found of a cadaver. I do not think he lied.
besides which there is no such thing as a scent of a cadaver, there is only the scent of decomposition. Even the early stages of this do not start in two or three hours, so a body will have had to be there for considerably longer than the gap between when madeleine was last seen, and when the police entered the flat. The chemicals that the dogs pick up, also do not stay there for more than four to five weeks, and the dogs did a search several weeks after this.
In short I do not think the forensic science service, or the british dog handler are lying or incompetant.
