Police rescued a frail-looking woman, sitting on a mattress in a locked metal storage container in the middle of a wooded area at SC, the United States, where she was chained up for two months.
Police at the farm said they found three bodies: Carver's, as well as those of Johnny Joe Coxie, 29, and his wife, Meagan Leigh McCraw Coxie, 25.
Investigators found three bodies on the property after going in search of Ms Brown and her boyfriend Charles Carver, 32, last November.
Now, the video of both the rescue and the confession are being released by SC prosecutors to the public.
In another video, Kohlhepp admits to investigators in a calm and chilling demeanor that he killed four people at a store in 2003 and jokes about his hard-to-read handwriting.
"I cleared that building in under 30 seconds", he tells investigators.
Authorities on Friday released video of Brown's rescue and Kohlhepp's confession.
Kohlhepp pleaded guilty to seven counts of murder, four counts of possession of a weapon during a violent crime, two counts of kidnapping and one count of first-degree criminal sexual conduct.
Police had gone to the property in November previous year after signals from Miss Brown's mobile phone indicated she might have been in the area when she vanished in August.
The story of Carver and Brown's disappearance is as dramatic as the moments of her rescue.
The shipping container was on a farm property owned by Kohlhepp, who previously worked as a real estate agent in Spartanburg, South Carolina. She also informs them that Kohlhepp had killed her boyfriend.
On the way to hospital, Miss Brown told police that Kohlhepp, 45, a successful estate agent, had also confessed to killing four people in a rampage at a motorcycle fix shop in a notorious unsolved crime 13 years earlier. "I'm sorry, but you guys would have been proud".
The serial killer was taken into custody in November after officers searching his property heard Brown banging on the inside of a storage container on his property.
But in the latter video two days later, Kohlhepp appears disconcertingly untroubled, even joking occasionally, as he describes how he killed seven people over 13 years. "It gives me heartburn", Kohlhepp said.
Once officers break through, they open the crate and begin their walk through.
She is sat on the floor with her hands on her head as the police enter.
"It was nearly like a video game", he said in the interrogation.
