More than five weeks after 84-year-old Nancy Guthrie disappeared from her Tucson-area home, investigators are now examining whether internet or power disruptions in her neighborhood on the night she vanished could be connected to the case. Multiple fresh reports say detectives have recently gone back to neighbors asking whether their Wi-Fi or electricity suddenly stopped working around the time Guthrie is believed to have been abducted.
That appears to be the newest publicly reported development in the investigation. Authorities have not said a device was definitely used, but the questioning suggests investigators are testing whether the suspect may have tried to interfere with cameras or home internet systems before or during the disappearance.
Nancy Guthrie, the mother of Today co-anchor Savannah Guthrie, was last seen after being dropped off at home on the night of January 31, 2026, and was reported missing the next day. Investigators have said they believe she was abducted from the home in the early hours of February 1.
Law enforcement still has not publicly identified a suspect or announced an arrest. Surveillance footage previously released by the FBI showed a masked, armed man near Nancy Guthrie’s front door, and investigators have described him as a man about 5-foot-9 to 5-foot-10 with an average build, carrying a black Ozark Trail Hiker Pack backpack.
One earlier potential clue has weakened. DNA found on gloves recovered near the case was traced to an uninvolved restaurant worker, according to recent reporting, meaning that evidence has not produced the breakthrough investigators hoped for.
Pima County Sheriff Chris Nanos said earlier this week that investigators are “definitely closer” to identifying a suspect or suspects, even though the case remains unresolved in public. At the same time, fresh canvassing has continued in the neighborhood, with FBI agents reportedly returning door to door to follow up on leads and tips.
Savannah Guthrie also made an emotional return to NBC’s Studio 1A this week after spending time in Arizona with her family. She had previously visited the memorial outside her mother’s home and thanked supporters for continuing to pray and hope for Nancy’s return.
The $1 million family reward remains in place for information leading to Nancy Guthrie’s recovery or to an arrest, and officials continue to ask the public for tips.
One important correction to the version you pasted: the idea that the suspect may be “watching the memorial” is expert speculation reported by Fox News Digital, not an official public statement from the FBI or the sheriff’s office. The strongest new reported development today is the internet/Wi-Fi outage angle, not a confirmed memorial stakeout.
