Investigators hunting for missing Arizona mother Nancy Guthrie in Pima County are now focusing on the possibility that the suspect is 'someone close' to her, as the search entered its 39th day on Tuesday, 10 March, with no arrest, no confirmed sighting and a quietly altered investigative strategy.
Guthrie disappeared on 31 January, prompting a major search involving the Pima County Sheriff's Department, the FBI and specialist teams. Her case has gripped local residents and online communities alike, not least because, despite intensive ground searches, digital forensics and door-to-door canvassing, investigators have still not publicly identified a suspect, nor have they recovered any confirmed trace of the missing woman.
