Nancy Guthrie, 84, was abducted from her home in Tucson’s Catalina Foothills late Saturday night after having dinner with her daughter Annie. Investigators report signs of forced entry at the property.

Authorities believe Guthrie was taken from her bed around 2 a.m. Sunday, when her pacemaker stopped syncing with her Apple Watch. More than four days later, the search to find her safely continues.

Her children, including TV host Savannah Guthrie, have publicly pleaded with the captors to provide proof that their mother is alive, sharing emotional videos as pressure mounts.

Experts told investigators that evidence strongly suggests the abductor was a stranger. Former FBI agent Dr. Bryanna Fox explained that forced entry makes it unlikely Guthrie knew her attacker or left willingly.

Guthrie’s phone and medications were left behind, and forensic teams found blood inside the home, further indicating she was taken against her will. Investigators say she could not have walked away on her own.

While stranger abductions of elderly people are rare, experts believe Guthrie was likely targeted after surveillance. Her age, limited mobility, living alone, and lack of home security increased her vulnerability.

Possible motives include financial exploitation or, more disturbingly, thrill-seeking violence. Authorities confirmed awareness of a Bitcoin ransom note sent to TMZ, though its authenticity remains unverified.

Search efforts are complicated by the area’s dense desert terrain and proximity to the US-Mexico border. Officials have not named a suspect and say critical details are being withheld as the investigation continues.
