Investigators might be looking at a new clue from Nancy Guthrie's security footage as the search for her continues. Pima County Sheriff Chris Nanos told NBC News on Tuesday, February 17, that it appears the suspect filmed on Guthrie's porch appeared to be wearing a ring underneath the pair of black gloves. "I look at the same photo you look at and I get - I see it," Nanos said in the interview. "I'm going to give that to my team. They'll look at that. They'll analyze it and we'll see. Maybe, maybe it is.
