Nancy Guthrie was last seen on Jan. 31 at her Catalina Foothills, Tucson-area home; when she didn't turn up for church the next day, authorities were notified; investigators later said the porch showed blood droplets and a Nest camera captured a masked suspect who even tried to cover the lens with leaves.
Her daughter, Today co-anchor Savannah Guthrie, has since offered up to $1 million for information that leads to her mother's recovery, while the FBI has also announced a $100,000 reward and says its tip line has been flooded.
