The investigation into the disappearance of 84-year-old Nancy Guthrie has entered a new phase after forensic analysis of blood evidence found at her Arizona home suggested she may have been alive when she was removed from the property.
Maureen O'Connell, a retired FBI special agent who has reviewed details of the case, told Brian Entin Investigates blood droplets discovered on the porch of Guthrie's residence in the Catalina Foothills show signs of 'aspiration'. The pattern indicates the blood may have come from breathing or coughing, suggesting Guthrie was likely still alive, though possibly unconscious, when she was taken from the home on 1 February 2026.
