About David: If he existed and since he’s supposed to be dead, then where would he be buried? Is he there in the family plot, next to his dad and granddad?

[Fred Nerks]

The only interesting thing about the mythical 'David' is that he looks like zero's TWIN and he's shown sitting there next to a little boy who is a little older and considerably darker, whom we next see with the kenyan student-son-of-a-goat-herder with Ruth and Mark - in a photo that must have been taken in Kenya because as far as we know, Mark was born in 1965 after Ruth married the said goat-herder's-son on Christmas Eve 1964. Once you get that sorted, the rest falls into place:

There's no grave...the younger boy is Mark, he lives in China, the older boy is probably the 31 year old law student interviewed at the Patrice Lumumba University in 1992. Remember?
