This raises one of the central issues about new reporting of such events - it often seems to serve pour encourager les autres, and no doubt even now desperate teenagers of every nationality are frantically searching the Internet to find out how this 14 year old managed to pull it off in such spectacular style using ingredients found in the bathroom cupboard. So: report the details, perpetuate the problem.
I was led in the end to a most peculiar Wikipedia page on suicide methods - which seemed to be to be nothing more than a "how-to" guide for those looking for an easy way out. The strange nature of this entire entry, which lists different methods in alphabetical order starting with "Beheading", is illustrated by the following entry under the distinctly American-sounding "vehicular impact":
"Jumping in front of a fast-moving vehicle, especially a large one, such as a truck or train, can prove fatal. A classic example of suicide involves one tying oneself to railroad tracks in order to be run over by an oncoming train. The self control required to stay on the tracks as the train approaches can be quite immense, and the result quite traumatizing to the driver of the vehicle."
Thanks for that! I had no idea!
