This is a tragic story, but the last line raises more questions than it answers:
Four children who vanished on their way to primary school have been discovered suffocated and buried on a ranch not far from their homes in southern Mexico, according to Tabasco state authorities.
Three of the children being buried on Saturday were siblings and another was their neighbor in the colonial town of Tapijulapa.
Their ages ranged from 7 to 10.
. . . .
Their faces had been covered with brown packing tape, which caused them to suffocate, the agency said in its statement issued Friday.
The motive for the killings remained unclear, but officials said there was no sign of organ trafficking.
No sign of what now?
This reminds me of what the correspondent says at 3:14 of this Monty Python sketch:
As a Naval officer I abhor the implication that the Royal Navy is a haven for cannibalism. It is well known that we now have the problem relatively under control.
Is organ trafficking a thing in Mexico now?
Of course not! They now have the problem relatively under control.
