The Tucson community is mourning the disappearance of Nancy Guthrie, mother of NBC “Today” co-host Savannah Guthrie, with a candlelight vigil planned for Wednesday evening. Authorities are treating her case as a possible abduction, noting signs of forced entry at her home and a ransom note sent to a local news station. Friends describe the Guthrie family as respected contributors to the community, and Savannah has called for prayers for her mother’s safe return. Anyone with information is urged to contact the Pima County Sheriff’s Department.
