Nancy Guthrie Update: Sheriff Chris Nanos explains why no arrests have been made, ‘You have the science to back it up…’

“It’s not like a detective goes out and talks to someone and we can arrest him,” Nanos said. “This is a very sensitive case, but what really causes the case to drag on is that we do rely on the labs.” “When you look at these labs and the work they do, you see there’s a science there, and science has rules that it has to follow. Even if it’s not… DNA, they’ll tell you, is not an exact science — it’s over 99 percent accurate. So it’s pretty close, but you still have to follow the rules.”

Nanos previously acknowledged in an interview with People that the Guthrie couple must be “frustrated” by the lack of answers. However, he seems convinced that answers will come.

“My team, I’ve always said, they’re going to fix this,” he said. “I believe that absolutely 100 percent. … When you have the best minds in the country working on problems, I think they’re going to solve them. It’s just going to take a while.”

More than a hundred days after Nancy’s disappearance, Nancy’s family no longer has any personal contact with Nanos. He previously claimed that all communications with Savannah and her siblings Anne and Karen were through other investigators working on the case. Nanos told PEOPLE that he has not been in contact with the family “personally” and that they have been communicating with local police detectives and FBI agents.
