When mother Julie Keith bought Styrofoam headstones from a local supermarket for Halloween, she found something more terrifying inside - an apparent plea for help from a Chinese forced labourer.
Oregon resident Mrs Keith found the letter in the pack of KMart decorations in October, and human rights experts have said the letter describes conditions which are known to be real in Chinese labour camps.
This individual letter cannot be verified as genuine.
It reads, with some words in the original Chinese: "Sir: If you occasionally buy this product, please kindly resend this letter to the World Human Right Organization.
"Thousands people here who are under the persicution [sic] of the Chinese Communist Party Government will thank and remember you forever."
The letter's author said the Halloween product was made in Masanjia Labor Camp in Shenyang.
