Kala Brown claims alleged serial killer Todd Kohlhepp kidnapped her, threatened her life and chained her inside a metal storage container for two months. The 30-year-old says Kohlepp, a local real estate agent, had hired her to clean a garage on his property, but when she arrived with her boyfriend, she claims Kohlhepp shot and killed him and then took her captive.

“He left me bound and he also put a chain around my neck,” she says, explaining that her neck was in one corner and her ankle was in another corner. She says Kohlhepp then left her and returned about two hours later.

“He let me know that if I tried to run, he would kill me. If I tried to hurt him, he’d kill me. If I fought back, he would kill me,” Brown says. “And then he raped me.”
