In a troubling development, sources from law enforcement have disclosed that Nancy Guthrie’s pacemaker lost connection with her Apple Watch early Sunday morning. This occurred as the 84-year-old woman, who is suspected to have been abducted, became disconnected from the watch around 2 a.m., according to reports from Fox News.

Authorities informed the media outlet that Guthrie’s Apple Watch was discovered inside her residence. This suggests that the device ceased ‘syncing’ with the pacemaker when the latter moved out of the watch’s Bluetooth range.

Apple Watches are equipped to connect with health devices such as pacemakers, allowing users to track vital health information through Bluetooth technology.

Pacemakers, which are surgically implanted, help manage abnormal heart rhythms by delivering small electrical pulses to the heart.

The data retrieved from the Apple Watch provides a potential timeline for the alleged abduction, shedding light on the disturbing details initially reported by the Daily Mail, which indicated that Nancy Guthrie was forcibly taken from her bed during the night.

The Apple Watch data offers a possible time of kidnapping and offers a horrifying fresh perspective on the Daily Mail’s revelation that Nancy was dragged from her bed in the dead of night. 

Law enforcement sources say that ‘blood drops’ were found leading from the entryway of the house to the driveway, and a doorbell camera she owned was removed by the time investigators arrived on Sunday. 

Officials previously said Nancy, whose daughter is Today show host Savannah Guthrie, was last seen at her home around 9:45pm on Saturday evening.

Pima County Sheriff Chris Nanos told the Daily Mail he believes she has been abducted, and said investigators found ‘concerning’ evidence of foul play at Nancy’s home. 

She was reported missing the next morning when she didn’t show up at church, and when her family went to her home they found her personal belongings including her wallet, cellphone, Apple Watch, and car, but no sign of the 84-year-old. 

Sources added to the LA Times that blood was found at Nancy’s home, alongside signs of forced entry.

An exhaustive hunt for Nancy continues, with the sheriff almost bursting into tears Monday night when asked if he thinks Nancy is still alive. 

Nanos welled-up after he was asked by AZFamily host Briana Whitney: ‘Do you believe you are still looking for Nancy Guthrie alive at this point? That she could be held somewhere? And if so, do you believe that is local in the Tucson area, or that she’s been taken somewhere?’

Nanos stumbled on his words as he said he and his deputies are ‘just not going to give up hope’ of finding Nancy – who officials say is frail and has been without daily medication she needs to survive.

Sheriff Nanos said they did not believe Nancy had been targeted because of her rich and famous daughter, but said he could not rule out that line of inquiry. 

Officials said Nancy Guthrie, 84, is frail with ‘poor mobility’, and requires medication that could be fatal if she does not take it every day

Nanos said that while the exact nature of Nancy’s disappearance remains unknown, investigators believe they are ‘looking at a possible kidnapping or abduction’.

‘She did not leave on her own, we know that,’ he said. ‘She’s very limited in her mobility.’

On Monday, Nanos appealed to a potential abductor while speaking with NBC.

‘Just call us. Let her go. Just call us. The family will tell you, there’s no questions asked here,’ he said.

Savannah’s father died of a heart attack while she was in high school, and officials said Nancy lived alone in her Tucson home.

An NBC source told CNN that Savannah was preparing to go to Europe to cover the Winter Olympics at the time, and had spent much of the last week with her children before she would make the trip.

Savannah, who only recently returned to NBC after throat surgery, is now set to remain off-air indefinitely.

With the search for her mother ongoing, Savannah Guthrie made a heartbreaking plea for fans to keep her family in their prayers.

‘We believe in prayer. We believe in voices raised in unison, in love, in hope,’ Savannah wrote on Instagram. ‘We believe in goodness, we believe in humanity. Above all, we believe in Him.’

‘Thank you for lifting your prayers with ours for our beloved mom, our dearest Nancy, a woman of deep conviction, a good and faithful servant,’ Savannah wrote.

She then asked her social media followers to ‘raise your prayers with us and believe with us that she will be lifted by them in this very moment,’ adding: ‘We need you’ and ‘Bring her home’.
