Investigators probing Nancy Guthrie's disappearance are focusing on a potential event at her Arizona residence three weeks before her abduction. Pima County Sheriff Chris Nanos stated that officials believe 'something occurred on Jan. 11' based on FBI analysis of equipment and digital evidence.
Nanos declined to elaborate on the evidence prompting the focus on that evening. Disturbing security footage shows a masked person at her doorstep on the night authorities suspect she was taken.
The search for the grandmother reached its seventh week, with her family urging people to 'search their memories' around key timelines, including January 31 and February 1, as well as the late evening of January 11.
