A week after Nancy Guthrie was last seen, authorities are still searching for the 84-year-old mother of "Today" anchor Savannah Guthrie and are investigating the authenticity of a new note.
Authorities believe Nancy Guthrie was taken from her home near Tucson, Arizona, and is in poor health without vital medication. She was last seen the night of Jan. 31, and her family discovered she was gone when she didn't show up for church the next day.
"We believe Nancy is still out there," Pima County Sheriff Chris Nanos said on Feb. 5.
Investigators are searching the area around her home as the timeline of her disappearance grows more concerning. Without daily medication, Nany Guthrie is at risk due to her health issues, and the first deadline associated with a ransom note has passed.
The FBI is offering a reward up to $50,000 for information leading to Nancy Guthrie's recovery or the arrest and conviction of anyone involved in her disappearance.
