The search for Nancy Guthrie, the 84-year-old mother of Today show co-host Savannah Guthrie, enters Day 25 with a surge of unexpected activity at her Catalina Foothills home near Tucson. Multiple unmarked vehicles and a convoy of black SUVs were seen arriving at the property, including one dark SUV that pulled directly into the garage and remained inside before leaving. Federal prosecutors were later confirmed to be on scene assisting the FBI with what officials described as a routine legal process, even as the Pima County Sheriff’s Department publicly claimed there was no activity at the house. In this episode of Drop Dead Serious, Ashleigh Banfield is joined by veteran homicide prosecutor Matt Murphy to break it all down.
