Fox News Digital reporter Michael Ruiz reported Friday that a private helicopter flew "what appears to be a comprehensive grid pattern above the Los Reales landfill today, about 18 miles from Nancy Guthrie's home." "While the flight path looks very much like a search pattern, PCSD says it has 'not been advised of a private helicopter assisting with this case." Friday marks 20 days since Nancy Guthrie, 84, disappeared from her home in Tucson, Arizona. Fox Multimedia reporter Asher Redd joins LiveNOW to break down the latest developments in the investigation.
