Kala Brown was found alive after two months in the container. Her boyfriend remains missing.
The neighbors of a real-estate agent accused in the kidnapping of a young woman held captive inside a metal storage container while "chained like a dog" say they've had a bad feeling about the suspect.
Todd Kohlhepp, 45, is accused of kidnapping 30-year-old Kala Brown and her boyfriend, Charlie Carver, over the summer. Kohlhepp appeared in court Friday.
Ron and Marlene Owen live next door to him. They found out online that he was a registered sex offender.
"I was concerned about it," Marlene told Inside Edition.
Ron recalled one troubling conversation he had with Kohlhepp: "My daughter comes to visit us, my daughter is a very beautiful young lady. Todd approached me and said, 'who is that foxy lady that comes to your house?'"
He added: "I have two granddaughters; they come to my house, for a moment I thought, 'what could have happened?'"
Brown was rescued Thursday by cops where she was found inside a padlocked container on Kohlhepp’s property in South Carolina. Her boyfriend remains missing.
Officers reportedly heard her banging inside the container and screaming: "Help me! Get me out of here!"
She was held for two months inside a steel four-foot-by-six-foot metal cage that was placed inside the 30-foot-long metal storage container.
And cops fear Kohlhepp may have committed additional crimes, including murder, and are investigating the possibility that he may be a serial killer. As many as four bodies have been found on his property.
Spartanburg County Sheriff Chuck Wright told reporters Thursday: “It was pretty emotional, to say the least, when [Brown] was found, especially when she was chained like a dog. She had a chain around her neck.”
He added: “It was only by God’s grace that we found [her] alive.”
Brown had worked for the suspect, cleaning houses before he put them on the market.
Kohlhepp's past is filled with evil deeds.
At age 15, he pleaded guilty to kidnapping a 14-year-old girl in Arizona. In that case, a judge said Kohlhepp had been, "aggressive and destructive since nursery school."
His own father said of him: "The only emotion Todd seems capable of showing is anger."

The judge also wrote: "Twenty-five months of the most intensive and expensive professional intervention, short of God's, will provide no protection for the public and no rehabilitation."
Shortly after Brown and her boyfriend vanished, Kohlhepp posted a bizarre Facebook message about missing persons.
"Reading the news, this person missing, that person missing, another person missing, oh, wait, that person just went to beach with friend. Other person found with her parole violation boyfriend,” he wrote.
