More than 100 days after 84-year-old Nancy Guthrie vanished from her Tucson, Arizona, home, Pima County Sheriff Chris Nanos has insisted in local TV interviews that detectives are edging towards an arrest, as FBI specialists analyse DNA and investigators pore over ransom letters sent to media outlets.
Guthrie was reported missing in the early hours of 1 February after being dropped off the previous evening at her property in Tucson by her daughter, Annie, and son-in-law, Tommaso Cioni. According to officials, that ordinary family dinner on 31 January was the last confirmed sighting of the pensioner. Since then, there have been no named suspects, no arrests and a growing sense, at least among some locals, that the case has stalled.
