Kohlhepp's mother Regina Tague also spoke to CBS about why her son had committed the crimes, and insisted that he had not sexually abused Brown.
"He said he did not,' Tague said. "He promised me. And believe me, he woulda told me."
Tague revealed that the reason he kept Brown locked up was that she had seen him kill her boyfriend.
"He didn't know what to do with her," she said. "Couldn't turn her loose. She'd go get the police."
She also believed that her son was 'misunderstood'.
"Todd is not a monster. He's not even close to it. He wasn't doing it for enjoyment. He was doing it because he was mad and he was hurt."
The investigation is currently ongoing and details continue to emerge.
Kohlhepp has already been charged with four gun murders dating back to 2003 and kidnapping Brown. He might be connected to seven deaths in total, according to Wright.
Scott Ponder, his mother Beverly Guy, service manager Brian Lucas, and mechanic Chris Sherbert were found fatally shot inside Superbike Motorsports in Chesnee, South Carolina, on November 6, 2003. The case stunned the community and baffled police for more than a decade.
Now, on the 13th anniversary of the murders, the families say Todd Kohlhepp's arrest will bring them some peace.
