Sheriff Nanos took questions from the media and clarified details on the alleged abduction which took place on February 1.

“Is there any indication that Nancy Guthrie is still alive?" CBS reporter Jonathan Vigliotti asked Nanos. "We know the medication played a critical role here. It's been 48 hours. She needs it every single day. Are you looking for someone who is still alive?"

Nanos replied: “We hope we are. We hope we are.”
