“I would see pictures of David and Kelly on Facebook, and it would just seem odd. I was seeing his arm around her, like a couple,” Christine says. “After my granddaughter was born, she looked like one of my kids. I asked Kelly point blank, ‘Is he touching you?’ She said, ‘No, he’s not.’”

Christine says she tried to continue to remain in contact with her children but claims David made it difficult. “David wouldn’t let me talk to the kids. Communication pretty much stopped after the first year. I wasn’t able to see them either,” she says. “After a few times trying to go through the court, I finally just threw my hands up in the air and said, '[Expletive] it. I’ll see them when they’re 18.”

Christine says it wasn’t until years later that her daughter called her and admitted that David had been molesting her since she was 11 and fathered her two children.
