Former Texas nurse William Davis was indicted on a capital murder charge
A former Texas nurse already charged with murder following the suspicious death of a patient faces an additional charge of capital murder.
William George Davis was previously indicted in June for one murder and two aggravated assault charges. His charges were amended this week to include one capital murder charge and three aggravated assault counts.

Davis, 34, was fired from Christus Mother Frances in February, weeks after hospital officials reported a number of suspicious deaths involving patients recovering from heart procedures.
He was arrested in April after police learned that Davis was the only employee consistently around each of the patients and surveillance video showed him entering and leaving their rooms moments before the patients experienced stroke-like symptoms.

On August 2, Greenaway was admitted to the hospital and received a coronary artery
