"I couldn't imagine having that happen and not knowing all those years," Gunnels said. "I really really couldn't."

Chris and Barry King have been going the extra mile to try and solve the case, not knowing if they have done any good.

"It was kind of a long shot that it would help," Chris King said. "But law enforcement said, 'Who knows. Sometimes these guys have remorse and they end up telling you things.' So, we went with that hope."

The conversation now is in the hands of police investigators who still hope to solve the case.

There is a grand jury investigation underway in Oakland County and a separate grand jury investigation underway in Wayne County. Several child sex offenders have been arrested and identified over the years as a result of the ongoing investigation. However, there has never been enough evidence to charge anyone in connection with the Oakland County Child Killer case.
