Nancy Guthrie, the 84‑year‑old mother of Today show anchor Savannah Guthrie, has now been missing for more than 100 days from her home near Tucson, Arizona, and fresh speculation about the case erupted this week after 'missing Nancy Guthrie' followers spotted new arrangements of rocks and cacti in the desert opposite her neighbourhood.
The curious display, highlighted in livestreams and social media posts, has prompted a wave of online theories about secret signals and warnings, even though investigators have not linked it to the official search.
