FBI investigators have recovered a series of 'mystery' thumbnail images showing unidentified individuals at the Arizona home of Nancy Guthrie in the days leading up to her disappearance, while the cameras appear to have captured nothing on the night she vanished, according to The Mirror US.
The images came from motion-activated cameras covering the pool, backyard and side yard at the 84-year-old's property, deepening questions about whether whoever took Guthrie knew the layout better than police first understood.
