A television documentary is shining new light onto one of the most notorious serial killers in South Carolina.

Todd Kohlhepp is serving life sentences in prison for killing seven people, including a 32-year-old from Anderson in 2016, a Spartanburg couple in 2015 and four people at a motorcycle shop in Chesnee 2003.

Kohlhepp, 48, was arrested Nov. 3, 2016 after Kala Brown was found chained up on his 95-acre Woodruff property. She had been missing from Anderson for more than two months with her boyfriend, Charlie David Carver, who was found dead on the property.

Johnny Coxie and Meagan McCraw-Coxie were also found dead there after Kohlhepp's arrest.

While in custody, Kohlhepp confessed to being the sole shooter responsible for killing four people — Scott Ponder, Brian Lucas, Beverly Guy and Chris Sherbert — inside Superbike Motorsports in Chesnee on Nov. 6, 2003.

Since his conviction, Kohlhepp has claimed he has more than seven victims.

"Serial Killer: Devil Unchained," advertised as the most comprehensive look into Kohlhepp's life and crimes, premiered on Investigation Discovery July 22. The second part aired July 29. Monday marked the third and final episode.

Here are the findings from part three:

The feet were missing from the bodies of Carver and Coxie when authorities dug them up from shallow graves on Kohlhepp's Woodruff property. Kohlhepp claimed that he had no idea why the feet were missing, but investigators said the way in which the feet were removed was suspicious. The feet were not chewed off by animals and not mistakenly removed from excavation machinery, investigators said.

"He made the comment that, 'My mother told me never to play with my food,'" said Tom Clark, a retired Spartanburg County investigators on the show.

In a letter to investigative journalist Maria Awes, Kohlhepp wrote "I kill. I don't play with bodies. This isn’t criminal minds."

Kohlhepp claims to have killed two other individuals before the Superbike murders in 2003 while living at Hunt Club Apartments in Spartanburg County.

He said he lived there after getting out of prison in Arizona and moving back to Spartanburg. He said he began getting harassed from other residents based on his sex offender status since he was convicted of a sexual assault when he was 15.

Kohlhepp said he told law enforcement about residents leaving flyers, calling him and harassing him, but law enforcement told him to "deal with it." So he did, he said.

"Two individuals decided to assault me, and they’re no longer with us," Kohlhepp said in a phone call with Awes.

Kohlhepp said one man was armed with a knife, the other with a hammer. He told biographer Gary Garrett that he felt he had no choice but to stab one of them in the chest and the other in the neck.

He told Garrett he dumped the bodies at a dead-end road off Interstate 26 between Spartanburg and Columbia.

The "Serial Killer: Devil Unchained" film crew accompanied a team of law enforcement to an area off I-26 to search for two bodies based on Kohlhepp's new tip.

The Greenville News first broke the news of the search in August 2018. The show credits The News for breaking the story, adding that the initial agreement made between Kohlhepp and law enforcement was to have no media involvement other than the film crew.

The team used the assistance of K-9s from the South Carolina Foothills Search and Rescue, a Simpsonville nonprofit organization. Earlier, the Sheriff's Office worked with Awes to identify three potential exits off I-26 that matched Kohlhepp's recollection but ultimately ended up searching off exit 41 in Enoree.

Some animal bones were discovered but no signs of human remains were ultimately found, Sheriff Wright said the day of the search.

Wright also sat down with Awes and explained that investigators did everything they could to investigate Johnny and Meagan Coxie's disappearance in 2015. The Sheriff's Office never used cellphone pinging as an investigative tool as they did for Brown's missing person case.

Wright claimed that since the Coxies were known to panhandle, they assumed they never had a cellphone. But incident reports obtained by the film crew show that an investigator had known of Meagan Coxie's phone and tried to call her but never got an answer.

For the Superbike case, Wright was asked about why Kohlhepp was never investigated even though he was documented to have been a prior customer. Wright said even with Kohlhepp's record of a sexual assault as a teenager, there was no evidence telling investigators he would be a likely suspect.

Wright said he is unsure if Kohlhepp does have more victims but does believe it is possible.

In the final portion of the episode, Kohlhepp explained that he would be willing to offer up more details of his additional killings if the state Attorney General's office would be willing to waive filing any additional charges against him.

Awes pointed out that the exit off of I-26 in Clinton did also match Kohlhepp's description of where he took his additional victims but no one ever agreed to search there.

"It's difficult to think there may never be closure," Awes said in the episode.

The show ends with a chilling letter from Kohlhepp from prison.

"Like a loose string on a sweater, once you start pulling you never know what it unravels," he wrote in a letter to Awes.
