Police in South Carolina have found another body at the sprawling 95-acre site where a woman was discovered "chained like a dog" and locked in a storage shed last week.

The human remains were uncovered in one of the two places that suspect Todd Kohlhepp had pointed to as gravesites.

Spartanburg County Sheriff Chuck Wright has said investigators are "not even close" on identifying the victim or the cause of death.

This is the second body to be discovered on Kohlhepp's property since the woman, who had been missing since late August, was brought to safety by detectives.

The first body was that of the woman's boyfriend, Charles Carver, and he had suffered multiple gunshot wounds.


Earlier on Sunday, Kohlhepp had appeared in court charged with the murders of four other people at a motorcycle garage in 2003.

The 45-year-old, who is a registered sex offender, had confessed to the massacre hours after the woman was discovered at his rural property.

His court appearance fell on the 13th anniversary of the mass shooting, which shocked and mystified the state and was left unresolved for years.

The hearing was attended by loved ones of the four victims, and they claim Kohlhepp was a disgruntled customer who had visited the store several times.

Kohlhepp was not represented by a lawyer at Spartanburg magistrates' court, and he was denied bail after declining two opportunities to address the bereaved families directly.

Investigators say Kohlhepp has given them information about the cold case that only the killer would know.

Police have warned they may make more disturbing discoveries as they trace Kohlhepp's steps since his release from an Arizonan prison in 2001.

As a teenager, he was convicted of raping a 14-year-old neighbour at gunpoint and threatening to kill her siblings if she called police.

Police officers, as well as FBI and Homeland Security agents, are now widening their investigation to properties currently or formerly owned by Kohlhepp - some of which may lie beyond South Carolina.
