Oh, no. This devastating information really helps to narrow down the timeline of Nancy Guthrie's disappearance. Nancy's pacemaker has reportedly stopped syncing with her Apple devices. A law enforcement insider told Fox News on Tuesday that Savannah's mother's medical device stopped syncing at around 2 a.m. on Sunday. Cops have previously said they believe the 84-year-old was taken from her home at some point between 1 a.m. and 4 a.m. on Sunday, so this would align with that. Nancy's phone and Apple Watch were left inside her house. Related: Cops Still Have No 'Solid Lead' In Search For Savannah Guthrie's Mother?! Now, let's be clear. This doesn't mean that her pacemaker isn't working. This is now the timeframe that investigators think she was taken out of range of the devices. How terrifying for her family to not have access to this vital information. And timing in the search is critical because Nancy takes a daily medication and not having it every 24 hours could lead to "fatal" consequences. Unfortunately, police are scrambling for leads at this time. We're hoping they find some answers soon! A tip line has been set up: see HERE. The Sheriff's Department is now offering a reward of up to $2,500 for images, videos, or information that leads to the arrest of a person or people involved in the disappearance.
