A body language expert is drawing attention to a chilling detail relating to the masked individual seen at the home of Nancy Guthrie before she went missing.Nancy, 84, disappeared from her Tucson, Arizona residence and was reported as missing on February 1.A widespread search was quickly launched after blood belonging to Nancy, mother of TODAY co-anchor Savannah Guthrie, was found at the scene. That search has now entered its twelfth day, with FBI images and video offering the first chilling glimpse of the suspect on February 10.The footage, pulled from a Nest security camera outside the property where Nancy vanished, shows a masked figure in light-colored clothing approaching the house at night.

In one frame, the person appears to be carrying a firearm in a way that immediately raised red flags for former FBI agent Mark Harrigan.“That is a very non-conventional way to carry a firearm. Very non-conventional,” Harrigan told The New York Post, pointing to what appears to be the weapon positioned at the front of the suspect’s body.“He has it in the open, which is unusual, because normally you would want it concealed when you’re going to do a crime, so you’re not calling attention to yourself with an exposed firearm,” he said.A body language expert has since weighed in on the footage, drawing attention to the suspect’s backpack.
