I'm reminded of an article I read way back about a teenage boy who had committed suicide. Except it wasn't suicide - he died of auto-erotic asphyxiation. But no family will let that be written in the papers (at least, not immediately) so they went with the story that he hung himself and was depressed.
There was another story recently of a girl who electrocuted herself in the bath when she dropped her phone into the water while it was plugged in. I was skeptical of that as well - who wants to tell people their child committed suicide by taking a toaster in the bath? Best just say it was the cellphone.
I don't blame the parents if this is their cover up.
