In season three's "Personal Day", a young man Julio put in prison for murder in 1997 gets released after seventeen years in prison and insists to Julio he's innocent despite overwhelming evidence and a confession. Julio refuses to believe the man and only reports his claims due to procedure. The man is later murdered and Julio is shocked to learn the man was innocent as he'd claimed, having confessed to murder rather than an armed robbery to protect his best friend. The squad are able to catch the true killer and Julio informs the man's ill grandmother of his innocence. To help make up for his mistake, Julio reopens the investigations into the murders of the man's father and uncle which had been unsolved for over twenty years.
