Nurse charged in case of pregnant patient

A nurse who was supposed to be looking after an incapacitated woman at a long-term health care facility has been accused of raping her, weeks after the patient stunned her caregivers by giving birth to a baby boy , Phoenix police said yesterday. Investigators arrested Nathan Sutherland, a licensed nurse, on suspicion of one count of sexual assault and one of vulnerable adult abuse, Phoenix Police Chief Jeri Williams said. ‘‘We owed this arrest to the victim. We owed this arrest to the newest member of our community — that innocent baby,’’ Williams said.
