Kayla Brantley

Nancy was last seen around 9.45 p.m.

on Saturday.

She was reported missing after she didn't show up to church the next morning.

A key digital clue has narrowed down the timeline.

Her pacemaker stopped syncing with her Apple Watch around 2 a.m.

on Sunday.

The watch was found inside of the home.

Police say Nancy is mentally sharp but physically frail.

She needs daily medication to survive and was taken without it.

Investigators are examining alleged Bitcoin ransom notes sent to TMZ and a former hostage negotiator says the evidence may suggest more than one person was involved.

The FBI is assisting and police say all leads are being followed.

But as of now, there is no suspect and no person of interest.

Savannah Guthrie said in part in a statement on Instagram, please pray.
