The search for Nancy Guthrie has been going on for two weeks now, and still, theres no sign of the missing 84-year-old.
Nancy mysteriously vanished from her $1 million home in Tucson, Arizona, on February 1, prompting an intense kidnapping investigation thats caught the attention of the entire country.
On Saturday evening, federal officials launched a rare signal sniffer that could hopefully help investigators track down her pacemaker.
Nancy, the mother of beloved Today Show host Savannah Guthrie, had her implanted medical device connected to her iPhone and Apple watch. Around 2.30am on the day of her disappearance, the pacemaker stopped syncing with her devices.
The signal sniffer, a compact device, was seen on the skids of the Pima County Sheriffs Department helicopter as it flew over the Tucson area Saturday night.
The latest move by investigators comes after authorities released a chilling video of an unidentified masked man, armed with a gun, trying to obscure the doorbell camera on Nancys front door.
Several people have been questioned in connection to with her disappearance, but were later released. A series of ransom notes have also been sent to media outlets, including TMZ, demanding at least $6 million in bitcoin from the Guthrie family.
