Nearly three months after 84-year-old Arizona grandmother Nancy Guthrie vanished from her Tucson home on 1 February, a former FBI agent has publicly floated a new theory about the case, suggesting it is more likely that more than one person was involved in her suspected abduction.
Nancy, mother of Today presenter Savannah Guthrie, disappeared from her upscale neighbourhood in the early hours of that Thursday morning. Investigators say a masked intruder was captured on her doorbell camera around the time she is believed to have been taken, and blood droplets found on the front porch were later confirmed as hers. No suspects have been named, and authorities have not said whether they believe a single attacker or a group was responsible.
