The mystery surrounding the disappearance of the 84-year-old mother of NBC News anchor Savannah Guthrie has deepened.
Nancy Guthrie disappeared in the middle of night from her home in Tucson, Arizona, on 31 January and authorities believe she was taken against her will.
Police in Arizona have not yet identified a person of interest in the suspected abduction and continue to investigate a series of apparent ransom notes that may have been sent from the person or people behind the alleged crime.
The Guthrie family has made several public pleas for her safe return and has asked for proof that their mother is still alive.
Guthrie was last seen at her home in Catalina Foothills, an affluent neighborhood roughly six miles (10km) north-east of Tucson, on 31 January evening, when family members dropped her off around 21:30 local time (04:30 GMT).
At 01:47 local time on 1 February, a doorbell camera to her home was disconnected and removed.
Concern grew when members of her church noticed her absence at the Sunday service and notified her family. Authorities began a search that included volunteers and federal officers from Border Patrol.
Authorities have been further puzzled by ransom notes referencing details exclusive to Nancy Guthrie's home.
FBI Special Agent Heith Janke stated his agency was reviewing these potential ransom notes, and they are actively seeking information that might lead to ongoing communication with the alleged captors.
As media coverage escalates, the Guthrie family, along with officials, maintain a public plea for help while navigating the psychological toll this abduction has posed on them.
