It is unbearable. And to think of what she went through.” “I wake up every night in the middle of the night, every night,” she continued. “And in the darkness, I imagine her terror. And it is unthinkable, but those thoughts demand to be thought. And I will not hide my face. But she needs to come home now.” Arizona Mar 21 Guthrie family thanks Tucson, asks people to not forget mother's case Arizona Mar 18 New images from Nancy Guthrie's home do not show suspicious activity, sources say Arizona Mar 14 Sheriff gives update on leads in Nancy Guthrie case, says he believes she may have been ‘targeted' Savannah has been with her family in Arizona amid the ongoing search for her mom.
