Police in Holland Township are investigating a death threat mailed to a family mistaken for residents who named their son Adolf Hitler Campbell.
However, her daughter's name is Heather and was listed in the phone directory under Campbell, H.
The typed, unsigned letter said her children would die and "you will all end up like your Nazi friends: dead."
Police tell The Easton Express-Times if they can find the person who wrote the letter, he would be charged with making terroristic threats.
The couple who wanted the birthday cake got it inscribed at a Wal-Mart in Pennsylvania.
