Investigators probe possible Wi-Fi jammer use in Nancy Guthrie’s disappearance, amid unconfirmed reports of internet outages and camera failures the night she vanished.

Investigators in the case of missing 84-year-old Nancy Guthrie, mother of “TODAY” co-anchor Savannah Guthrie, are exploring whether a Wi-Fi jammer was used to disrupt her home’s security systems, after neighbors reported internet outages and camera glitches on the night she vanished. Authorities, including the FBI and Pima County Sheriff’s Department, questioned residents about connectivity issues, though no confirmation of interference has been made. The case remains active, with a $1 million reward offered by the family and no suspects identified.
