TUCSON, Ariz. — More than a month into the search for Nancy Guthrie, officials continue to chase thousands of leads as her family leans on the "love and prayers" from their Arizona community and beyond.
"I think the investigators are definitely closer," Pima County Sheriff Chris Nanos said in an interview Monday about the progress of the case.
"I've said this from the beginning: I have full faith, full confidence, they're going to solve this," Nanos said, adding that there have been “thousands” of leads since Guthrie, 84, the mother of "TODAY" co-anchor Savannah Guthrie, disappeared.

Guthrie was reported missing Feb. 1 after she didn’t show up at a friend’s home in Tucson to watch an online church service. She was last seen around 9:45 p.m. Jan. 31 after having had dinner with her family, officials said.
The FBI has joined local law enforcement in the search, and the Guthrie family is offering a $1 million reward for her recovery.
On Monday, Savannah Guthrie, with her sister and brother-in-law, visited the growing tribute of yellow flowers outside their mother's home and left their own.
Savannah Guthrie shared a photo on social media of the flowers and other items left in support of the family. She once again thanked people from the area and across the country for their love and support.
