Yes, although whether or not we find humour in that kind of stuff is is heavily nuanced and context-dependent, even within the narrow genre of kiddie rape and murder.
I think the reason Maddie is such a comedy goldmine is because of the whole circus surrounding the case, and the fact that her white middle class parents blatantly killed her, which *is* inherently funny.
There are other cases where small children were brutally murdered that you'd struggle to find any humour in.
You don't hear any jokes about Jamie Bulger, for example.
Madeline McCann is ripe to mine for humour content purely because hers is an unsolved case with no proven evidence as to any crimes attached to her
A bit like Shergar really
To this day he might be living it up on a stud farm somewhere in the Bhamas
10 characters? Pile of cund.
The dental hygienist gave me a mirror to admire my teeth when he'd finished yesterday. I did a big grin and remarked, "Ah, that's what happened to Shergar" - not a flicker of recognition from the fellow. Mind you, he was about 23 and Indian. But imagine not remembering Shergar.
