Excavation and search work is done Monday on Todd Kohlhepp's property in Woodruff, S.C. Kohlhepp was arrested for kidnapping a woman and keeping her in a storage container on his property.

WOODRUFF, S.C. — Investigators discovered a third body on the property of a South Carolina man who is now linked to seven deaths and the kidnapping of a woman who was found chained inside a storage container, authorities said Monday.

Todd Kohlhepp, 45, became a suspect after the woman was found Thursday chained by her neck and ankle in a metal storage container on his 95-acre property near rural Woodruff.

The body of her boyfriend was found a day later. The couple had been missing for about two months.

The other remains were found near one another Sunday and Monday, and authorities are not sure who they are. Investigators were expected back at the property on Tuesday, but Spartanburg County Coroner Rusty Clevenger said he didn’t think there were any more bodies.

“As the coroner, that’s all I have been advised of. That was the total number of bodies I was told was on the property. If I am told there are more, I will be back,” he said.

Following Kohlhepp’s arrest, he confessed to a 2003 quadruple slaying at a motorcycle shop in the small town of Chesnee, said Spartanburg County Sheriff Chuck Wright. He was denied bond Sunday on four murder charges for gunning down the motorcycle shop’s owner, service manager, mechanic and bookkeeper.

Wright has said Kohlhepp gave details only the killer would know. His confession came a day before the 13th anniversary of the crime, which many feared would never be solved.
