TUCSON, AZ. ― Nancy Guthrie's presence was missing Wednesday inside the sandstone-colored walls of St. Andrew's Presbyterian Church in Tucson, where she was a devout congregant.

She was missing in the city’s eclectic downtown at El Charro Café, a favorite of the 84-year-old, who sat there with her famous daughter Savannah Guthrie on a recent visit last year.

On the fourth day since the morning show mom was allegedly abducted Jan. 31 from her sprawling home in the region's affluent Catalina Foothills, she was missing there too, as investigators revisited the home.

But her place in the community was fully present on Feb. 4 as anguished residents and supporters flocked to a nearby church, framed by the scenic Santa Catalina Mountains, for a vigil to pray for her safe return.

And whether she’d be found before going too long without her vital daily medication.
