The investigation into the disappearance of 84-year-old Nancy Guthrie has entered its third week, with Pima County Sheriff Chris Nanos facing mounting criticism over his handling of the case. Recently, Nanos defended his decision to send DNA evidence to a private lab in Florida instead of the FBI's Quantico facility, stating, "It made sense to keep that in one place" to avoid splitting evidence. This decision has drawn ire from federal officials, who argue that it has delayed the investigation, which has already cost over $200,000 in outsourced analysis. As of now, law enforcement has received over 30,000 tips, and Nanos remains optimistic, asserting, "The family believes she's alive. I believe she's alive," despite the lack of leads in the case.
