TUCSON, Arizona — The search for Nancy Guthrie, the 84-year-old mother of “Today” co-anchor Savannah Guthrie, has entered another critical phase as authorities intensify efforts using advanced aerial technology.

Law enforcement confirmed that a specialized detection device — described by officials as a high-powered “sniffer” — has been mounted to a Pima County Sheriff’s Department helicopter currently operating over parts of Tucson.
The device is capable of scanning areas within a range of up to 800 feet and is designed to ᴀssist investigators in detecting human remains or other biological indicators that may guide the search.
The deployment of the technology signals the seriousness of the ongoing investigation into Nancy Guthrie’s disappearance.
She was last seen on January 31 at her Tucson residence and was reported missing the following day after failing to attend a scheduled engagement.

Authorities have previously stated they believe Nancy was forcibly removed from her home. Surveillance footage released earlier showed an unidentified suspect wearing a mask and gloves near her front door.
Investigators have since collected physical evidence, including gloves recovered in the surrounding area, and forensic testing remains underway.
Meanwhile, Savannah Guthrie has continued to publicly plead for her mother’s safe return. Over the weekend, she shared a touching throwback video of Nancy on social media, writing, “We will never give up on her.”
