US authorities say a registered sex offender has confessed to seven killings, after a woman was found chained alive in a storage container. <br /><br /> Todd Kohlepp, 45, apparently told police that he was behind four deaths at a motorcycle shop in 2003 and also led authorities to the site of two more bodies on his South Carolina property. <br /><br /> This after another body was found at the site on Friday. That has been identified as the boyfriend of 30-year-old Kala Brown, who was inside the locked container – and is described as having been chained up at the neck, “like a dog.”<br /><br /> The couple went missing in August. <br /><br /> Brown is said to have told authorities that she saw Kohlepp shoot her partner. <br /><br /> The county sheriff says more bodies could be found. <br /><br /> Officials have also told the media that Brown and Kohlepp knew each other and that her abduction was not a random act.<br />
