Ronica Copes of Lindenhurst posted the letter on Facebook on Thursday:
Copes did not immediately respond to a request for comment from The Huffington Post.
County executive Steven Bellone said he hopes the person who wrote the letter is discovered and punished.
“To the coward who committed a hate crime against an innocent family in Lindenhurst — There is no place for intolerance in Suffolk County,” Bellone said in a statement obtained by PIX11. “I know the Suffolk County Police Department will do everything possible to solve this hate crime, out you and see you punished.”
Though the letter says Lindenhurst is 84 percent white, the village of around 27,000 people is roughly 86 percent white, according to 2010 Census data.
