Rafael Barba Barba leaves the DA's office midway through the nineteenth season, in the episode "The Undiscovered Country." His regrets over having left his father on life support in a diabetic coma lead him to disconnect the life support system for a comatose infant whose parents have been feuding over whether to do so. DA Jack McCoy (Sam Waterston) insists on prosecuting him for murder. Although he is acquitted, Barba decides that it is time to move on, after 21 years as a prosecutor.[8]
