The desperate search for 84-year-old Nancy Guthrie has entered its third week with no signs of her being found.
The mother of NBC News anchor Savannah Guthrie was last seen on January 31, and now authorities are issuing a warning that finding her could take months or even years.
{img}Pima County Sheriff Chris Nanos mentioned more about how law enforcement remains fully committed to this investigation, but admitted the lack of solid proof and leads that make this entire case's timeline so uncertain.
{img}Investigators mentioned more about how she was abducted by force from her residence, and while several people were detained for questioning, no arrests have been made so far.
She left behind key items like her phone, purse, and medication. Blood was also collected from her porch, and footage of a tampered doorbell camera showed a masked person on her property, reinforcing suspicions of a forced kidnapping.
