Carl Smith collided with a concrete lamp-post while skating and suffered a skull fracture that caused a coma. When he failed to regain consciousness, his parents on August 8 consented to his life support machine being turned off.
Carl Smith died.
Carl Smith's life support was turned off - Carl Smith would have therefore died. Difficult for the system because the context never actually specifically states that he dies.
