Authorities were seen towing an SUV from Nancy Guthrie’s home and removing a wired device from the roof after a neighbor flagged something that “didn’t belong.” The sudden activity stunned the block as investigators moved fast, sealing off the area and working in silence.

Law enforcement agents confiscated a SUV parked inside the garage of Nancy Guthrie’s Arizona home Friday, where they also removed a wired device from the roof after they received a tip from a neighbor.

Over 10 police cars converged on Guthrie’s residence in the Catalina Foothills north of Tucson and began searching the property in the late afternoon amid the large-scale search for the missing 84-year-old.

A tow truck was called in and removed a Blue Subaru SUV — believed to be owned by Guthrie — before police escorted the truck to an impound lot near the Pima County Sheriff’s Office, Fox News reported.
