Drawing on the past to help sex slaves

After escaping years of sexual slavery, Jennifer Kempton could not look in the mirror without being taken back to her dark, traumatic past.

On her neck was tattooed the name of one of her traffickers along with his gang's crown insignia. Above her groin were the words "Property of Salem" - the name of the former boyfriend who forced her into prostitution nine years ago.

"Slaves have been branded for centuries and it's just evolved into being tattooed. It's happening all over the world," said Kempton, who suffered horrific brutality during six years working on the streets of Columbus, Ohio.
