Nancy Guthrie disappearance: Day 85 latest updates

Nancy Guthrie, the 84-year-old mother of NBC 'Today' show host Savannah Guthrie, has been missing for 85 days. Authorities believe she was abducted from her Tucson-area home between Jan. 31 and Feb. 1. The FBI is analyzing DNA evidence from her home, including hair samples, using new enhanced technology. Pima County Sheriff Chris Nanos denied reports that another person was detained in connection to her disappearance. A northern California forensics lab, which helped crack the Long Island Gilgo Beach serial killer case, is believed to be involved in the case. The Pima County Sheriff's Department is increasing patrols in Nancy Guthrie's neighborhood due to complaints about social media influencers on their property. Savannah Guthrie returned to the 'Today' show on April 6, amid the ongoing search for her missing mother.
