Police heard Kala Brown's desperate screams coming from the makeshift prison where she was locked in and repeatedly raped by serial killer Todd Kohlhepp for two months.
When she is asked about her boyfriend Charlie Carver, who Kohlhepp also kidnapped, she calmly says: "Todd Kohlhepp shot Charlie Carver three times in the chest, wrapped him in a blue tarp, put him in the bucket of the tractor, locked me down here.
Authorities say on the way to the hospital, Ms Brown told them about how Kohlhepp confessed to killing a married couple before she was captured, and about killing four people at a Spartanburg County motorcycle shop - murders that were unsolved for 13 years.
He bragged in one video of wearing gloves when loading his gun to assure no fingerprints were on the casings.
He also told authorities he pulled the gun apart and threw the components into different trash bins, putting the barrel into a bag of used kitty litter.
