SPARTANBURG, S.C. -- A South Carolina serial killer already serving life in prison for seven slayings told authorities he has two additional victims buried near an interstate, a sheriff said Tuesday. Spartanburg County Sheriff Chuck Wright said investigators are bringing Todd Kohlhepp to the county to lead them to the supposed location of the bodies, the Greenville News reported. 
 
 "We're trying to get a game plan together to find out exactly where and what to do. Investigators have been talking to him," Wright said. "We're not going to try to keep that quiet. We're going to go search." 
 
 Kohlhepp told investigators that two people are buried near Interstate 26 in Spartanburg County in the northwest part of the state. Wright is unsure who the supposed additional victims are or exactly where they are, he said. 
 
 "We haven't been able to confirm anything he's claimed yet," Wright said. "It's not to say that the details are not sketchy because it's been so long, but we're obligated to go check." 
 
 Kohlhepp is serving seven consecutive life sentences without parole at Broad River Correctional Facility in Columbia after pleading guilty to multiple charges in May 2017. "48 Hours" investigated the case in the episode, "Buried Truth." 
 
 His string of crimes was uncovered in 2016 after police rescued Kala Brown from a storage container where she was chained at the neck and investigators found a body buried in a shallow grave. Brown told investigators she saw Kohlhepp shoot and kill her boyfriend, 32-year-old Charles Carter, who went with her for a cleaning job on Kohlhepp's property in rural Spartanburg County. 
 
 Kohlhepp raped Brown while holding her against her will, and told her he had also killed a husband and wife in December 2015, burying their bodies on his land. Johnny Joe Coxie, 29, had been killed immediately, and Kohlhepp kept 26-year-old Meagan Leigh McCraw-Coxie alive for six days before shooting her in the back of the head on Christmas, Solicitor Barry Barnette said. 
 
 The Associated Press typically doesn't identify victims of sexual assault, but Brown has spoken publicly about her traumatic experience. 
 
 Kohlhepp admitted to her that he had killed four people in the Superbike motorcycle shop in November 2003, the prosecutor said. The owner, Scott Ponder, 30; Beverly Guy, 52; Brian Lucas, 30; and Chris Sherbert, 26 were killed because Kohlhepp thought they were making fun of him. Guy was Ponder's mother and worked as a bookkeeper. Lucas was a service manager, and Sherbert was a mechanic at the shop. 
 
 Kohlhepp's crimes took place over more than a decade as he ran a real estate business. 
 
 According to the plea agreement signed by Kohlhepp, he will serve seven consecutive life terms plus 60 years on kidnapping, sexual assault and other charges. Kohlhepp will not be eligible for parole, and he also agreed not to appeal the sentence. 
 
 Kohlhepp moved to South Carolina in 2001 shortly after 14 years in prison for pleading guilty to kidnapping in Arizona. Authorities there said the then 15-year-old forced a 14-year-old neighbor back to his home at gunpoint, tied her up and raped her. 
 
 Friends and co-workers at Kohlhepp's real estate business said he was a hard worker with some strange habits. He would watch pornographic videos during work and joked on his firm's website that he motivated workers by not feeding them. ||||| The Upstate's most notorious serial killer's claim that there were two more bodies buried in Spartanburg County led to a search Wednesday that failed to turn up anything, officials said. 
 
 Sheriff Chuck Wright said Tuesday that Todd Kohlhepp claimed the bodies were in the Enoree area.

 "He didn't tell me. He didn't tell our investigators. He told somebody who told us," Wright told WYFF News 4 Tuesday night. 
 
 Lt. Kevin Bobo released the following statement after the search concluded: 
 
 “When Todd Kohlhepp was arrested in November, 2016, he made vague statements to our investigators about committing two homicides prior to the Superbike incident. 
 
 “At that time, we researched his statement and found no evidence to support his claim. 
 
 “Since his incarceration at the S.C. Department of Corrections, he made that same claim to a production company that is filing a documentary about his crimes, but his account to that company differed in some details and also included possible locations of these two alleged victims. 
 
 “Last week, two of our investigators went to the Department of Corrections and interviewed Kohlhepp. Some of the details he shared with our investigators differed from what he had shared with the production company; specifically, that the victims were buried in one location as opposed to two different ones. 
 
 “Those investigators asked Kohlhepp if he would be willing to show us the location of these two alleged victims. Todd Kohlhepp declined that request. 
 
 “Monday and Tuesday, our investigators met with the production company and compared notes to see what was consistent in Kohlhepp’s claims and what wasn’t. That additional research led to numerous deputies and cadaver dogs searching a wooded area at the dead end of a frontage road at Highway 92 and I-26 in Enoree. 
 
 “Again, we didn’t find any evidence to support his claim. At present, there aren’t any plans to go back to the site tomorrow, and that lead will be suspended until Kohlhepp decides to share more detailed information that can be verified.” 
 
 Maria Awes, senior vice president of Committee Films, confirmed in a statement late Wednesday afternoon that her company is working on the Kohlhepp documentary. 
 
 “We are currently on the ground filming an exclusive documentary series about Todd Kohlhepp, airing next year on the true crime and justice channel, Investigation Discovery (ID). 
 
 “As this is an active investigation, we are working closely with law enforcement to be completely transparent with our information and filming only within their specified parameters.” 
 
 Tuesday, Wright had said he felt like he was "between a rock and a hard place" because Kohlhepp killed seven people, so they had to check it out. 
 
 The search for more victims 
 
 Deputies and K-9's began to search about 9 a.m. 
 
 “This will be the last time this happens until he gives me some specifics that I can corroborate, because I don’t want it to be one of those things – he wants to stay relevant,” Wright said. “If he’s got more victims, I promise you, there are no limits to what we won’t do, within the law. I am obligated to see if there are anymore victims here, and if so, we’ll do the best we can to find them, and we’ll work it from there.”

 Wright said he didn't want to give more attention to Kohlhepp, but he owed it to the families of possible victims to follow up. 
 
 Dozens of vehicles lined the road near the heavily area where the search took place. The film makers who are producing a documentary on Kohlhepp's victims were also at the scene. Wright said he allowed them to shoot the search "from a distance." 
 
 He said the nonprofit group Foothills Search and Rescue's dogs were used in the search. Wright said the dogs are capable of finding bodies several feet underground, even if they have been buried for years. 
 
 Wright said if they had found any spots they wanted to investigate further, there was an industrial X-ray machine at the scene that is capable of detecting items buried 5 to 7 feet underground. 
 
 Kohlhepp is an admitted serial killer 
 
 Kohlhepp, 47, is serving seven consecutive life sentences plus an additional 60 years in prison after admitting he killed seven people and sexually assaulted a woman that he held captive in a storage container in November 2016. 
 
 Kohlhepp confessed that he killed Beverly Guy, Scott Ponder, Brian Lucas and Chris Sherbert in November 2003 at Superbike Motorsports. 
 
 He confessed to the Superbike Motorsports killings after investigators found Kala Brown, a woman who had been reported missing, on Nov. 4, 2016, chained inside a storage container on Kohlhepp’s property in rural Woodruff. 
 
 She had been reported missing two months before. In the days that followed, authorities also found the bodies of Brown's boyfriend, Charlie Carver, and Meagan Coxie and Johnny Coxie buried on Kohlhelpp's property.

– One of South Carolina's most notorious serial killers claims to have buried two more bodies near an interstate—but a full day of searching Wednesday failed to find any remains. Police using cadaver dogs searched an area near Interstate 26 in southern Spartanburg County without success after receiving information from a production company making a documentary on Todd Kohlhepp, who is already serving life for seven murders, CBS News reports. Sheriff Chuck Wright said there would be no more searching without new information. "At present, there aren't any plans to go back to the site tomorrow, and that lead will be suspended until Kohlhepp decides to share more detailed information that can be verified," he told WYFF4, adding that while he doesn't want to give Kohlhepp more attention, it is his duty to families of potential victims to investigate. "This will be the last time this happens until he gives me some specifics that I can corroborate, because I don't want it to be one of those things—he wants to stay relevant," he said. (Kohlhepp has previously said he won't disclose how many people he killed.)
