A third body has been discovered on the 100-acre property owned by the South Carolina man who authorities say had a woman chained up "like a dog" there in a storage container. 

CNN reports that authorities discovered the third body close to where another unidentified body had been found a day earlier on the property of Todd Kohlhepp, a 45-year-old realtor and registered sex offender who'd previously served 15 years in prison for kidnapping.

Kohlepp was arrested last week after an anonymous tip led deputies to his rural farm, where they found a missing woman screaming for help from inside the 30-foot-long metal storage container. The woman, Kala Brown, 30, told authorities that she'd watched Kohlhepp shoot her boyfriend to death. The boyfriend's body was also discovered on the property.

After Kohlhepp was apprehended, he reportedly told deputies that there were several bodies hidden on the farm. He also confessed to a 2004 cold case in which four people were murdered at a motorcycle shop in Chesnee, S.C. The Washington Post reports that investigators believe Kohlhepp is linked to at least seven killings, and the investigation goes beyond just South Carolina. 

NBC News is reporting that several disturbing Amazon reviews have been linked to Kohlhepp, including one for a shovel that reads, "Keep in car for when you have to hide the bodies," and another for a knife that says, "Haven't stabbed anyone yet. When I do it will be with a quality tool like this." Other reviews from the Amazon user named "Todd Kohlhepp" were for a chainsaw and padlocks, among other items.
