TUCSON, Ariz. — Authorities are intensifying their investigation into the disappearance of 84-year-old Nancy Guthrie, with a focus on events occurring weeks prior to her vanishing from her Tucson residence.
A neighbor informed Fox News reporter Sarah Alegre that investigators personally visited her home, seeking video footage captured on January 31.
This neighbor further explained that a Ring app alert indicated that investigators were also interested in surveillance footage from two specific periods: January 11 between 9 p.m. and midnight, and January 31 from 9:30 to 11. The alert did not clarify whether these times were a.m. or p.m. Additionally, it mentioned a “suspicious vehicle on Via Entrada around 10 a.m. on January 31.”
The Pima County Sheriff’s Department clarified to Fox News that the alert did not originate from their office. Instead, it was generated by a local resident who included links directing to the PCSD evidence submission site.
John Nantz, a former FBI agent, noted that when law enforcement concentrates on specific dates and tight time frames, it often indicates an effort to corroborate known activities and piece together a potential path of movement.

When asked whether specifying times points to timeline validation or tracking a vehicle’s movements, Nantz said, “They’re likely piecing together a route.”
Nantz added that targeted canvassing often follows the recovery of key surveillance footage, such as Ring video, as investigators seek to fill gaps and alert residents who may not realize they possess relevant evidence.
“It’s likely they’re canvassing since the Ring footage was recovered in case individuals may now realize they might be in possession of valuable evidence,” he said.

Guthrie’s family members say she was dropped off at home between 9:30 p.m. and 9:45 p.m. Saturday, Jan. 31. Her garage door closed at 9:50 p.m., according to authorities.
At 1:47 a.m. Sunday, Feb. 1, authorities say, the doorbell camera at Guthrie’s home disconnected, followed by a security camera detecting motion at 2:12 a.m. Her pacemaker disconnected from an application on her phone at 2:28 a.m.

Family members checked on Guthrie at 11:56 a.m. after she reportedly did not attend a weekly gathering where she normally watched a livestreamed church service.
Authorities were called and arrived at her home shortly thereafter.
