Trapped and terrified, it has been revealed the 30-year-old was fed one meal a day and was bound by neck and feet inside a box police have described as a “shark cage that you would put underwater”, placed in the storage container.
Brown was locked up with her boyfriend Charlie Carver, 32, who was later shot dead in front of her allegedly by Kohlhepp, the 45-year-old property owner and local real estate agent who police say has since admitted to seven killings.

Soon after Brown was rescued by police, Carver's body was found alongside another missing couple on the property.
In a 48 Hours special which just aired on CBS in the US, Spartanburg Sheriff Chuck Wright said Brown was understandably "distraught, panicked" when she was found.
"She was banging very hard on the container," Sheriff Wright told CBS.
"She was bound. There was a chain from the top of the cage to something else that went around her neck. She was distraught, panicked."
Brown says she was vere rarely allowed outside of the container. She also reportedly told her family that Kohlhepp dragged her to the graves on his property and threatened she would end up in one if she tried to escape.
WATCH: Detective Bradley Whitfield cried speaking to the media about finding Kala Brown.
His mother, Regina Tague, insists her son is "not a monster".
"He’s not even close to it," she told 48 Hours. "He wasn’t doing it for enjoyment. He was doing it because he was mad and he was hurt."
She said she hates that he has has been labelled a "serial killer".
"I know that’s what they say… he was a very misunderstood."
Police say Kohlepp has also admitted to gunning down four people in a notorious 2003 cold case known as the "Superbike Murders".
"They laughed at him, made jokes at him," Tague said.
"Everybody’s hurt. He hurt everybody."
Kohlhepp has been charged with kidnapping and murder.
