A small black child, Ames Glover, disappeared from Southall in 1990, abducted by a stranger. The case was not much reported on at the time, and has not become well known since. Wikipedia, as good an indicator of public interest as any other, has an article of 7,500 words on the McCann case, and nothing at all on Ames Glover.
The little boy has never been found. And, looking at the circumstances, it seems as if one of the reasons for the public obscurity is that you can't make as good a story out of the Glover incident. It did not occur as a tragedy in paradise, but in Southall. The parents were not rock-solid respectable marrieds, but had already split up. And, I'm sorry to say, it seems to be harder to make a good story out of a missing black child than out of one with blond hair and blue eyes. But both the McCann case and the Glover are equal tragedies. Twenty years after Ames Glover's disappearance, his mother Shanika Ondaatje said, heartbreakingly: "I have lived in the hope that one day I will find out where he is or what became of him." She said it to the Hounslow Chronicle. No one else was interested.
