The first interview was published on Thursday, and the second was published on Monday, May 18.What Chris Nanos Really SaidWhat made headlines from the interview was Sheriff Nanos' claim that he is "personally" not in touch with Guthrie family, even as the probe into the kidnapping continues.“I personally am not,” the Sheriff said about his current relationship with the Guthrie family. “If they need the family for anything, they get in touch with them and the family. It works both ways.”“We text or, every now and then, a phone call,” he continued. “But no, I've not even sat down with her face-to-face. She's got a lot on her plate. The FBI and my detectives and those, they've been talking with her face-to-face. She doesn't need to talk to me.”Shamik is a journalist covering the United States for Hindustan Times.
