"I was downstairs washing clothes and I noticed a little room leading under the stairwell. I thought, 'What the hell is in here?'" Mundy said. "I turned the light on and couldn't believe what I saw."
Mundy said Gravenmier knew his collection had been discovered because Mundy took a photo and hid it in the house, but Gravenmier noticed the photo missing and found it.
That's when Mundy said he went to the Charleston Police Department, reported Gravenmier and offered to take a lie-detector test.
"They didn't investigate it, because if they had, they would have found everything," Mundy said. "They came back and said there was no substance to [the allegations], or something to that affect."
Charleston police have no record of an investigation into Gravenmier from the '70s, according to the department's records division. Mundy said he tried to tell Gravenmier's wife about the abuse he uncovered but she stayed with her husband.
"She just gave me this look like, "'I know,'" he said. She died in 1998.
Mundy said he later divorced Gravenmier's daughter because she stood by her father.
During a sentencing hearing in April, Assistant U.S. Attorney Rob Livergood in Missouri said Gravenmier had abused children since the early '70s and would hand out candy in hopes of abusing them. Sometimes, he threatened or intimidated his victims, Livergood said.
Benson said she's undergone extensive psychological counseling to live with the pain that Gravenmier caused her. After the FBI caught Gravenmier in 2012, Benson gave agents a photo album of her and her childhood friends to help identify victims in Gravenmier's collection.
Benson said she wants to meet other victims, to share the trauma.
"I guess you don't know until you've lived it," she said. "I think about it every single day, I swear to you -- every single day."
