I have used this example before.
Amaral's depiction of Harrison's role:
The most plausible scenario is the following: there is no doubt that Madeleine is dead, and her body is hidden somewhere in the area around Praia da Luz. He praises the quality of the work carried out by the Portuguese authorities in trying to find the little girl alive. According to him, the time has come to redirect the searches in order to find, this time, a body hidden in the surrounding area.
AMAZING STATISTICS
Great Britain has at its disposal the world's biggest data bank on homicide of children under five years old. Since 1960, the count is 1528. Harrison is well acquainted with its contents. He often draws information from there which helps him to resolve similar cases. Valuable information can be found there on on various criminal modus operandi, places where bodies are hidden, techniques used to get rid of a body. He relates that on one occasion, thanks to the data, he was able to deduce the maximum distance a body might be found in relation to where the crime had been committed.
The figures quoted in the report he hands over give us the shivers. The crimes, including those of a sexual nature, are committed by the parents in 84% of cases; 96% are perpetrated by friends and relatives. In only 4% of them is the murderer or abductor a total stranger to the victim. In this roundabout way, Mark Harrison points out that the guilty party may be a person close to Madeleine, and even her own parents. From now on, we have to explore this track, especially as the others have proved fruitless.
(Edit to follow) ....
And the penultimate sentence and paragraph of Harrison's third and final report:
I am currently of the opinion on the available information and statistical datasets that if death has occurred, that it is possible that Madeleine McCann’s body has been disposed into the sea at Praia da Luz. (See my second report entitled “NPIA OP TASK Search Doc Beach and Marine”)
