No, Binkle, people who object to lurid speculation are not thickies who cannot understand that sometimes, very sadly, parents are guilty of harming their children.
My POV is that fabricating details about a very real little girl's disappearance for your own entertainment is nasty, to say the least. Read some crime fiction, or watch CSI, or something if you want that kind of stuff.
And kicking someone when they are down is pathetic. Most of all, the decent way to respond to the parents of a missing child is with sympathy unless and until it is shown as a fact that they are responsible.
