Savannah Guthrie is urging her mother Nancy's Tucson neighbors to carefully re-examine anything they saw or heard in early February, saying she believes the people living around the 84-year-old "hold the key" to solving the disappearance as the search moves into its seventh week.
In a new family statement shared over the weekend, Guthrie and her siblings thanked residents in Tucson and across southern Arizona for their help so far and asked them to think back on any unusual people, vehicles, or sounds near Nancy's home around the time she vanished.
The message says the family "continues to believe it is Tucsonans, and the greater southern Arizona community, that hold the key to finding resolution in this case" and stresses that "someone knows something," according to People.
Nancy Guthrie was last seen the night of Jan. 31 at her home in the Catalina Foothills area outside Tucson, after relatives dropped her off around 9:30 p.m., and she was reported missing the next day when she failed to show up for church.
Investigators say she is believed to have been taken from the house during the night, and her doorbell camera was found disconnected shortly before 2 a.m. on Feb. 1.
Pima County Sheriff Chris Nanos has said from early in the investigation that the home is being treated as a crime scene and that evidence at the property led authorities to call in homicide detectives, which is not standard in a missing person case.
Officials have emphasized that Nancy had mobility issues and could not have walked far on her own, reinforcing their belief that she did not simply wander away, Tucson reported.
Local and federal agencies, including the FBI, are still working the case and reviewing tens of thousands of tips, but they have not named a suspect or announced a major breakthrough. Previously released footage showed a masked individual near the home, yet investigators have not been able to identify that person.
Guthrie has returned several times to Tucson to meet with investigators and visit her mother's home, and has used national television and social media to keep attention on the case.
The family has also offered a substantial reward for information leading to Nancy's safe return, while asking that anyone with even small pieces of information contact law enforcement rather than dismissing them as unimportant, as per KSAT.
