A former FBI profiler has claimed investigators in Arizona could identify the person responsible for Nancy Guthrie's disappearance within weeks, after new CCTV footage appeared to show a masked figure near the 84-year-old's home outside Tucson between 31 January and 1 February.
Nancy Guthrie was abducted from her home more than three months ago and has not been found. The Pima County Sheriff's Department and the FBI have repeatedly appealed for information, but have not named a suspect or publicly identified a person of interest. Public interest in the case has remained intense, fuelled in part by Guthrie's connection to her daughter, US television journalist Savannah Guthrie.
