Constanza 'Connie' Ocana is an agent with the CIA.
She was an elimination expert, a paid assassin who had earned her nickname of the Blood Angel more than once, all in the service of the top floor of at Langley.
Was an agent is more accurate at the time we meet her in the first recorded adventure. She had decided she had had enough and found a way to exit the scene of a mission leaving everyone, including the Agency top brass, believing she was dead. She returned to Mexico and started a new life, one which find her to meeting a man named Michael, falling in love and marrying him, and created her precious daughter Julieta.
Then, in the opening pages of that tale, we would read how a group of cartel soldiers had gone after a target in a busy marketplace and a horrific explosion had resulted and her family was gone. Some might say her survival was a miracle but to Ocana, it was a curse as it left her alone and heartbroken. The terrible event would have one added unpleasant result for Ocana; news coverage of the memorial afterwards would capture an image of her grieving by the makeshift shrine and an eagle-eyed data analyst at Langley would recognize her.
Back into her world would come her old friend and mentor, the now aged Wes Parker, and while his deeply felt affection for her would have been enough to make him drop everything and come to her side, despite having believed like everyone that she was dead, with Parker as with the CIA in general, there is also another motive.
For Ocana, though, her motivation is simple - revenge against the cartel who took her life from her. Once that could be taken care of, then she could worry about what the Agency was going to demand of her.
