The woman who was held prisoner by South Carolina serial killer Todd Kohlhepp, who murdered her boyfriend and six other people, has filed a lawsuit against her captor's real estate company.

Kala Brown was raped and locked inside a container for more than two months after Kohlhepp shot and killed her boyfriend, authorities said.

The 30-year-old victim has filed against Todd Kohlhepp & Associates, LLC, also known as TKA Real Estate, which was registered as a business by Kohlhepp in 2009.

According to the lawsuit, filed in March, Kohlhepp hired Brown to clean homes sold and managed by the company.

Brown is suing TKA Real Estate for damages as well as physical and emotional injuries sustained while she was held captive.

The lawsuit alleges Kohlhepp was hired by the company after he was ruled to be a competent fit for the position, 'despite having full knowledge of Kohlhepp's violent criminal history and conviction for kidnapping as well as his status as a registered sex offender,' according to FOX Carolina.

Last week, Kohlhepp admitted killing seven people over nearly 13 years while running the successful real estate business.

He admitted his crimes less than seven months after he was arrested when investigators checking on a missing couple rescued a woman chained inside a shipping container on Kohlhepp's Spartanburg County property.

Kohlhepp pleaded guilty so he would avoid the death penalty.

Emotional family members of the victims packed the courtroom as Kohlhepp plead guilty.

They then read out emotional statements detailing how his sickening acts had destroyed their loved ones.

The father of victim Meagan Coxie said: 'May God have no mercy on his soul.'

According to the terms of the plea agreement signed by the 46-year-old Kohlhepp, he will serve seven consecutive life terms plus 60 years on kidnapping, sexual assault and other charges. He will not be eligible for parole, and he also agreed not to appeal the sentence.

Kohlhepp admitted Friday that he killed four workers at Superbike Motorsports motorcycle store in Chesnee in 2003 after the manager made him angry.

The victims were the owner, Scott Ponder, 30; Beverly Guy, 52; Brian Lucas, 30; and Chris Sherbert, 26. Guy was Ponder's mother and worked as a bookkeeper. Lucas was a service manager, and Sherbert was a mechanic at the shop.

Kohlhepp also admitted guilt in the deaths of a husband and wife who disappeared in December 2015.

The bodies of 29-year-old Johnny Joe Coxie and 26-year-old Meagan Leigh McCraw-Coxie were found on Kohlhepp's 95-acre tract of land after his arrest in November 2016. The couple had been hired to do work on Kohlhepp's property.

Kohlhepp was eligible for the death penalty, but the plea deal took that off the table.

No one has been executed in South Carolina in more than six years because the state lacks the drugs needed for lethal injections.

Kohlhepp moved to South Carolina in 2001 shortly after 14 years in prison after pleading guilty to kidnapping in Arizona. Authorities there said the then 15-year-old forced a 14-year-old neighbor back to his home at gunpoint, tied her up and raped her.

Kohlhepp's reign of terror came to an end on November 3, 2016, when police searching his Woodruff property heard a woman's screams coming from a shipping container.

Kala Brown later told police that she came out to the property two months prior with her boyfriend, Charlie David Carver, for a cleaning job.

After finding Brown and arresting Kohlhepp, investigators searched the property and found Carver's body in a shallow grave, along with the remains of two other people.

Those remains were later identified as Johnny and Meagan Coxie.

Kohlhepp told investigators that he shot Johnny when he tried to rob him. He then locked up Meagan in the storage container and kept her there for six days before shooting her dead as well.

While in police custody, Kohlhepp also confessed to the 2003 quadruple murder at the motorcycle store.
