(WXIA) -- An anonymous hate-filled letter is trending online after it was sent to a Canadian family.
The letter targets 13-year-old Max Begley, who has a severe form of autism.

Last week, the letter showed up at Max's grandmother's house. It complained about the boy playing in the yard and so much more, overwhelming his mother Kathy as she read it.
"You had a retarded kid. Deal with it properly," the letter said. "What right do you have to do this to hardworking people?"
The letter ended by saying, "Do the right thing and move or euthanize him."
Max doesn't know about the letter, but Canadian police do and they are investigating.
