MIAMI, Nov 6, (APP/AFP) – A man who was arrested in the US state of South Carolina for holding a woman hostage and “chained like a dog” has confessed to up to seven killings, a local sheriff said.

Wright said that the suspect had also shown authorities two gravesites on his vast property, in addition to one body dug up from a shallow grave on Friday. “There’s no wondering anymore” about the November 2003 killings at
