A disturbing new video shows the shocking moment that South Carolina sheriff’s officers discovered and freed Kala Brown from the cargo container she was being held in on the property of Todd Kohlhepp. The footage, which was originally tied to a November 2016 investigation, was released Friday.

After hearing cries for help, officers used a crowbar to pry the container doors open. Once open, they located Brown inside chained to the side of the container.

The video shows Brown’s legs chained to the floor of the container and her neck chained to the wall of the container. It also reveals some food containers and a few novels which Brown used to pass the time while being held hostage.

Officers found Brown on November 3, 2016, while looking for her boyfriend, Charlie Carter. Officers followed the last ping from Charlie’s cell phone to the area. During the rescue, officers asked the 30-year-old victim where her boyfriend was.

She quietly replied, “Charlie? He shot him.” The stunned officers asked, “Who did?” Brown replied, “Todd Kohlhepp shot Charlie Carter three times in the chest, wrapped him in a blue tarp, put him in the bucket of the tractor, locked me down here. I’ve never seen him again. He says he’s dead and buried. He says there are several bodies dead and buried out here.”

Officers would soon learn that indeed Brown was right; there were several bodies buried on his property. Kohlhepp, who had kidnapped Brown and kept her as a sex slave, was actually a serial killer who killed seven people over a span of fourteen years.

Four of those murders took place at a Superbike shop, according to Kohlhepp, who detailed every murder to investigators in exchange for a plea deal. Kohlhepp explained that he killed 30-year-old Scott Ponder; 52-year-old Beverly Guy; 30-year-old Brian Lucas; and 26-year-old Chris Sherbert for an undisclosed reason.

The 46-year-old serial killer bragged about the murders telling the detective, “That was one big building. I cleared that building in under 30 seconds,” Kohlhepp explained. “I’m sorry, but you guys would have been proud.”

The other two victims, besides Brown’s boyfriend, were a married couple, 29-year-old Johnny Coxie and 26-year-old Leigh McCraw-Coxie. Kohlhepp lured them to his property with the promise of work in December 2015. He stated that he killed them and buried them on his property in shallow graves.

Kohlhepp was sentenced last month with a plea deal that took the death penalty off the table. However he will serve seven consecutive life sentences, one for each of the victims, plus an additional 60 years for the kidnapping of Brown.
