Nancy Guthrie's disappearance has taken another turn in Tucson, Arizona, after a video posted online appeared to show lights on inside her Catalina Foothills home in the early hours of the morning, prompting renewed speculation about her daughter Annie Guthrie and son-in-law Tommaso Cioni.
The footage, shared by Lauren Serpa and reshared on social media, has not been verified by authorities, and there is no evidence linking the couple to the case.
