When Kala Brown accepted a job to clean a house for Todd Kohlhepp, a local real estate agent, she says she expected it to be like the five previous times she had worked for him. But instead of picking up keys and going to the property on her own, this time, she claims Kohlhepp escorted her to his isolated property in South Carolina.

Brown says that when they arrived at the property, they drove a half-mile down a road to a two-story garage, where Kohlhepp told Kala and her boyfriend, Charlie Carver, that he wanted them to clear brush. As the couple waited for Kohlhepp outside the garage, she claims he appeared with a gun. Brown says before she knew it, Kohlhepp had shot Carver three times in the chest, killing him.

“I got lost. I didn’t know what was going on. I just stood there,” Brown says, of watching the man she hoped to marry die in front of her.

She says that Kohlhepp then grabbed her by the neck and told her to get inside the garage, or she would “join Charlie.”
