Have you seen this story making the rounds? It is so horrifying that someone could even put this on paper:
What is wrong with people? A woman who claims she is a mother sent a vile letter to a family of a boy with autism, suggesting that they move elsewhere or euthanize him (yep, you read that right).
Apparently, the "noise pollution" 13-year-old Max of Newcastle, Ontario creates disturbs her and her children, so she wrote an anonymous typed notecalling him an "idiot" and suggesting that Max’s family "take whatever non-retarded body parts he possesses and donate them to science."
This link to the rest of the story also shows a copy of the letter: http://www.ivillage.com/viral-twitter-photo-letter-mom-teen-autism/6-a-544776 
Some people are just horrible, and am glad to see the neighborhood rallying around the family. It wouldn't surprise me that the letter writer is acting all innocent within the crowd :(
