Police investigating the disappearance of Arizona grandmother Nancy Guthrie have increased patrols around the Tucson home of her daughter Annie Guthrie and son in law Tommaso Cioni in recent weeks, according to local reports, prompting fresh public speculation over whether detectives are closing in on a new suspect.
The renewed police presence comes three months after Nancy Guthrie vanished and weeks after Pima County Sheriff Chris Nanos publicly said members of the Guthrie family were not suspects. KVOA News 4 Tucson has reported more frequent patrols in the neighbourhood where Annie and Tommaso live, as well as near Nancy Guthrie's home, but local authorities have so far described the activity as a response to harassment rather than a sign of a new direction in the investigation.
