I've been following the story on FB and from what I've read, the letter is directed toward an autistic boy and was put on their front door in the middle of the night. I read that the mother of the boy has MS. They went to the police but they were told nothing could be done about it. It's sick to think that this hateful woman is raising children ... who are most likely learning how to hate, also. :-(
ETA: They took it to the media and their story was covered by their local news. There is an interview with the family here:
I hope they find the bitch and press charges!
