Nancy Guthrie suspect made one ‘rookie’ mistake on night of kidnapping, expert says

In the past day, investigators have reported new movement in the disappearance of 84-year-old Nancy Guthrie, including the brief questioning and release of a person of interest and the public release of surveillance footage from her Tucson home. The FBI video shows a masked individual in light clothing approaching the house at night, and a former agent says the way the suspect appears to handle a firearm could point to a serious mistake. Authorities continue to review the footage as the search enters its eleventh day.
