High-profile desert kidnapping with elusive leads and intense scrutiny

Eighty-four-year-old Nancy Guthrie, mother of Today co-host Savannah Guthrie, remains missing weeks after an apparent abduction from her Tucson-area home, despite extensive desert searches and national attention. Investigators are analyzing biological evidence, including gloves and samples from her home, but DNA has not matched any FBI database hits and no arrests have been made. The case has featured ransom notes, disturbing video, possible suspect photos, and theories ranging from a botched burglary to a targeted kidnapping, while Savannah Guthrie and public figures issue emotional pleas and authorities field criticism over media exposure and investigative setbacks.
