On Nov. 3, 2016, after about two months, pings from Kala Brown and Charlie Carver's cell phones, as well as Facebook messages mentioning local realtor Todd Kohlhepp, led investigators to Kohlhepp's rural, 99-acre property. They heard cries for help from inside a storage container located there.

Once the locks were broken, investigators had a first-hand look inside the dark prison created by Todd Kohlhepp.

Kala Brown was found in the back of the 30' by 15' metal container, chained around the neck "like a dog." When asked about her boyfriend, Charlie Carver, Brown replied "He shot him." 

Brown explained that Todd Kohlhepp shot Carver to death, and then kept her as a sex slave on the property.

Kala Brown was forced to sit virtually all day, as well as sleep on dog beds provided by Todd Kohlhepp.

Todd Kohlhepp provided Kala Brown with nourishment, such as these crackers, and supplied books, adult coloring books, and a MP3 player -- among other forms of entertainment -- during her captivity. 

A stockpile of food items and other supplies were also found inside Todd Kohlhepp's shipping container. 

Among the supplies found in the container were firearms and a virtual treasure trove of ammunition.

Also on Todd Kohlhepp's property was another structure. Kala Brown told authorities that her captor would transport her there, always bound in some way, from time-to-time.

In the building's garage was a tractor. Kala Brown says that after Todd Kohlhepp shot Charlie Carver, she saw Carver's body wrapped in a tarp, and that Kohlhepp buried him somewhere on the property.

Also located inside the building's garage were numerous firearms. Some were located inside cabinet drawers.

Todd Kohlhepp confessed to authorities that he murdered Charlie Carver, as well as six others over the years. The serial killer pleaded guilty to all seven murders, along with kidnapping and rape charges for Kala Brown on March 29, 2017.
