Tucson Missing Case: Nancy Guthrie's Disappearance Treated as Criminal Investigation

Nancy Guthrie, 84, the mother of NBC's Savannah Guthrie, is still missing in Tucson. Pima County Sheriff’s officials say evidence at her home is concerning, and the case is being investigated as a crime rather than a standard missing-person case. Search efforts include ground crews, dogs, drones, and a sheriff’s plane and helicopter; investigators warn time is critical because she relies on medication. Savannah Guthrie and NBC News have publicly urged tips to help locate her.
