Holly Eudy was in a relationship with serial killer Todd Kohlepp for a decade before discovering his sinister past.
After he was arrested for murder Eury told Inside Edition, 'I knew there was something that didn't sit right with me about him, but I couldn't really put my finger on it.'
Kohlhepp, a 45-year-old real estate agent from Spartanburg in South Carolina, US, was arrested last November after a woman he'd kidnapped was found chained by the neck inside a storage container.
After the woman was found on his 95-acre property, scores of buried bodies were uncovered.
Surviving victim Kala Brown told police that Kohlhepp had shot her boyfriend, Charlie Carver, in front of her - and that he'd buried several other people on his property.
Eudy describes her former partners crimes as 'sickening' and 'disgusting', but she maintains that she was unaware of his cruelty and violence.
When asked what attracted her to Kohlhepp, she said: 'He gave me a lot of attention, made me feel like I was important.'
Kohlhepp has since pleaded guilty to killing seven other people, including the murder of four people that had gone unsolved for 13 years. He was sentenced to seven consecutive life sentences, without the possibility of parole.
