New details have emerged about the ordeal of a woman who was chained up inside a shipping container by the South Carolina serial killer accused in seven killings. Todd Kohlhepp was charged with kidnapping after investigators found 30-year-old Kala Brown – who had been missing for two months – chained up 'like a dog' inside a storage container on his property in rural Woodruff. In a '48 Hours' special that aired on on Saturday, it was revealed that Brown was kept in a cage inside the container, bound by her neck and feet – and fed just once a day. The container was dark most of the time, but Kohlhepp would let her out occasionally to walk around. Scroll down for video. Brown was kept in a dark cage inside a shipping container (pictured), bound by her neck and feet – and fed just once a day Brown told her family that Kohlhepp once dragged her to graves on his property and threatened that she would end up in one of them if she tried to escape, CBS News reports. She and her boyfriend Charles Carver had been missing since Labor Day weekend.

After Brown's rescue earlier this month, authorities found the body of 32-year-old Carver and another missing couple on Kohlhepp's property. Brown was kept inside what Sheriff Chuck Wright described as a 'shark cage that you would put underwater' and 'distraught' when police found her Brown was kept inside what Wright described as a 'shark cage that you would put underwater' and 'distraught' when police found her.

'She was bound,' Wright told CBS reporter David Begnaud. 'There was a chain from the top of the cage to something else that went around her neck.' Dan Herren, who was once in a relationship with Brown's mother, told CBS that Brown had opened up about her ordeal, but did not reveal if she had been sexually assaulted – and he'd not asked. 'She goes 'I was locked up in this metal container he had chains around my neck and I was in the dark almost the entire time.' He added: 'Her words were, 'And then Todd dragged me over to somewhere on the property where he showed me three graves that had to be – or that appeared to be people buried in them.' 'And Todd said to her, 'Kala, if you try to escape, you're going directly into one of those graves.' Kohlhepp's mother Regina Tague said her son had taken care of Brown by bringing her food and drinks as well as something to lie on Authorities have yet to release further details about Brown's ordeal, but Kohlhepp's mother Regina Tague insists he did not sexually abuse Brown.

'He said he did not,' she told CBS. 'He promised me. And believe me, he woulda told me.' Tague added that her son had taken care of Brown by bringing her food and drinks as well as something to lie on. But she added: 'I want her to know how sorry I am. And I think Todd is, too.

Because he didn't wanna hurt her, he just didn't know what to do.' Asked why her son had tied up the woman, she told CBS it was because she 'saw him kill her boyfriend, and he didn't know what to do with her. Couldn't turn her loose. She'd go get the police.' Tague says Kohlhepp told her he killed Carver 'because he got nasty and was smart mouthed'. As to why he'd killed the owner and employees at Superbike Motorsports in Chesnee, Tague said Kohlhepp wanted to return a motorcycle and 'they laughed at him, made jokes at him.' Tague also insisted that her son is not a monster, but just 'very misunderstood'.

Carver's body was found in a shallow grave on Kohlhepp's property She said: '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.' But Tom Lucas, the father of slain service manager Brian Lucas, said he's heard differently.

'I think he had a purchase of a bike that didn't go well. He messed it up and ended up getting it stolen and came in and bought another bike,' Lucas told the AP. 'They were kinda playing with him, laughing at him, saying, 'You gonna mess this one up?' Or something like that. Something that small just set him off. Nobody deserves to die over a comment like that.'

Lucas said Kohlhepp's name was among a list of customers he gave authorities more than a decade ago - but he never heard Kohlhepp's name as a suspect until last week. 'That's a huge, huge weight that's been lifted,' Lucas said. But he wonders, 'how many more victims — how many more families are sitting worried to death about their loved one and have no answers?' Service manager Brian Lucas (left) and mechanic Chris Sherbert (right) also died in the 2003 massacre Taken to the Woodruff property last Saturday, Kohlhepp showed investigators two gravesites.

Authorities identified the people buried there as 25-year-old Meagan Leigh McCraw-Coxie and her husband, 29-year-old Johnny Joe Coxie, of Spartanburg. They had been missing since December. Tague said her son told her there are no more bodies on his property. 'There's nothing else you have to worry about,' Tague says Kohlhepp told her.

But she's defended her son before. At age 15, he was sentenced to 15 years in an Arizona prison for binding and raping a 14-year-old neighbor at gunpoint. His mother asked for leniency, according to court records obtained by WHNS-TV in South Carolina. 'Todd knows he did wrong and he's sorry, but they won't even give him a chance to make a good life out of this. Install Camera Raw Photoshop Cs5 Portable Free more. They don't even stop to think that he even walked the girl home.

Does that sound like a dangerous criminal?' She wrote to an Arizona probation officer in August 1987. Kohlhepp's parents divorced when he was an infant. He moved in with his father in Arizona around age 12. Meagan and Johnny Joe Coxie (pictured) had been missing since last December. Their bodies were found and identified this week Kohlhepp had psychological problems from a young age, records show. An Arizona judge wrote in 1987 that he was 'very bright' but also 'emotionally dangerous' and preoccupied with sex.

A memo detailing a psychiatric evaluation notes that he grew up in South Carolina and Georgia and had counseling from around age nine. The memo, with a Phoenix hospital's letterhead, states that as a juvenile he threatened suicide, destroyed his bedroom with a hammer, hit other children and killed goldfish with bleach. A 1987 pre-sentencing report says a neighbor described Kohlhepp as a 'devil on a chain.' A probation officer wrote that the neighbor said 'Todd locked her son in a dog kennel cage and rolled it over and over. Despite the fact that her son was crying and screaming, Todd was laughing.'

Another time, she said Kohlhepp banged her son's head against clay pipes. Court documents show that Kohlhepp's father, mother and stepfather all had difficulty raising him. The document says the father told authorities he was 'never successful in getting the youngster to open up' and had to reprimand him for being a bully.
