An ex-FBI agent has warned that the suspect in the disappearance of 84-year-old Nancy Guthrie in Tucson, Arizona, may have made a 'risky' error by allegedly visiting her home on 11 January, weeks before she was kidnapped on the night of 31 January.
Former FBI special agent Jennifer Coffindaffer said the new detail, highlighted in a weekend statement from the Guthrie family, suggests the masked figure seen on FBI-released doorbell footage carried out a 'trial run' before the abduction.
