Authorities say the DNA match on the blood-stained porch confirms what Savannah Guthrie’s family already feared: something violent happened before Nancy disappeared. Yet investigators still have no suspects, no confirmed abductor and, crucially, no proof of life. Cryptic ransom notes sent to media outlets mention money, an Apple Watch and a floodlight, but offer nothing to show Nancy is alive.

Nancy, 84, was taken from her Tucson home after being seen there the night of Jan. 31. She missed a church service the next morning, triggering the alarm. Physically fragile and without the daily medication she needs to survive, she remains at the center of a desperate, widening search. The FBI has put up a $50,000 reward, while Savannah and her siblings plead publicly for direct, verifiable contact — and for one sign that their mother is still out there, waiting to be brought home.
