DNA Deluge Keeps Guthrie Case From Cooling, Sheriff Says

Pima County Sheriff Chris Nanos says the investigation into Nancy Guthrie’s abduction remains active and not cold, noting investigators are sorting through a large volume of DNA and video evidence more than 25 weeks after the Tucson home invasion, as Savannah Guthrie released a new Instagram plea to her mother’s kidnappers; a federal source says Guthrie consulted with law enforcement before releasing the video, and experts caution the case isn’t cold until all leads are exhausted.
