Unable to find a match for Adam in databases of missing children in Britain and Europe, investigators made requests to the public for assistance. However, the story initially only received moderate publicity, due its proximity to the
September 11 terrorist attacks in the
United States. In the UK, coverage and interest in the case increased over the next year, and rewards were offered for information leading to the killers' conviction, or to Adam's identification. However, the story had not yet received much publicity in Nigeria. The police subsequently travelled to Nigeria and launched a campaign to track Adam's parents. Despite visiting elementary schools and looking at reported missing children in the region, there was no success. The Metropolitan Police believe the publicity surrounding the case has acted as a deterrent for further ritual crimes in the United Kingdom. ==Linked cases==
