'Serial Killer: Devil Unchained': New ID Series Exposes Todd Kohlhepp's Darkest Secrets

SPARTANBURG, SC — The shocking crimes of Todd Kohlhepp first made national headlines in November 2016, after Kala Brown was rescued from a shipping container on his property in rural South Carolina.

Brown told police that, after killing her boyfriend in cold blood, Kohlhepp raped her repeatedly and kept her chained like an animal as his captive. But investigators soon discovered that these horrific crimes were only the tip of the iceberg.

The life and horrific crimes of convicted serial killer Todd Kohlhepp are the subject of a new Investigation Discovery limited series entitled Serial Killer: Devil Unchained.

"As a troubled young teenager, Todd Kohlhepp was described as a 'devil on a chain' by those who knew him best, but no one could anticipate what would happen when that chain was let loose," a press release for the series reads.

Kohlhepp would eventually plead guilty to seven murders, including the killing of four people at the Superbike Motorsports shop. Brown told Spartanburg County Sheriff’s investigators that the former real estate broker was responsible for "more crimes than local police ever knew possible."

In the new three-part limited series, filmmaker and investigative journalist Maria Awes teams up with former FBI profiler John Douglas in an attempt to uncover the truth about Kohlhepp's darkest secrets.

With the help of Kohlhepp’s former colleague and biographer, Gary Garrett, they track down people from Kohlhepp's past including his first known rape victim in Tempe, Arizona; a former lover; police who investigated the case; and Kohlhepp himself.

The series will take a look back at Kohlhepp's teen years in an attempt to identify early warning signs. Awes will also delve into questions surrounding the Superbike murders, the possibility that Kohlhepp could have had an accomplice, and perhaps the most important question of all: Could there be more victims out there?
