Encouraged by the fact that they now had a motive, but being completely unfamiliar with occult-related crime, detectives went on a research trip to South Africa, where they consulted with the local police department's occult unit and spoke to traditional healers and shamans.
One "sangoma" or medicine man they spoke to—Credo Mutwa—told them that the ritual sacrifice of Adam was likely to a water deity called Oshun and would have been carried out by a gang of people strengthening themselves magically to do some "very ugly crimes". The medicine man added that the orange shorts found on Adam's torso would have been put on after his death and that the colour orange was sacred to Oshun.
It all seemed so very plausible.
Yet according to Adam Kuper, a professor of anthropology at Burnel University, in the West of England, who grew up in South Africa, however, what Credo Mutwa said is all nonsense.
"The police claimed, quite wrongly, that a Yoruba [West African] river god, Oshun, is associated with the colour orange, and that human sacrifices are made to him," he said, "...no sacrifices of this kind have been documented for more than a century."
Kuper went on to dismiss Scotland Yard's investigation of the Adam case as nothing more than "a farrago of contemporary myths" about witchcraft and Africans. As far as he is concerned the police have "busily reinforced dangerous delusions".
