Ex-NYPD inspector says Nancy Guthrie’s kidnappers may have no proof of life

As the search for Nancy entered its seventh day, investigators conducted a renewed overnight operation in Tucson, Arizona.

Law enforcement officers were seen returning to the home of Savannah Guthrie’s sister, Annie, late Saturday evening, where they spent several hours inside the property photographing parts of the home until about 10:30 p.m. local time, according to the Daily mail.

A silver suitcase was also observed being brought into the house by an officer, although authorities have not disclosed what was seized.

The house had been searched earlier in the investigation, after police confirmed that Annie and her husband, Tommaso Cioni, were the last known people to see Nancy alive after a family dinner on January 31.

The renewed activity came just one day after investigators towed a vehicle from Nancy’s garage and removed a camera from the roof of her home — evidence that appeared to have been overlooked in previous searches — as officials continue to search for answers in the increasingly disturbing case.
