Luisa Cruz is there when Pamela Isley brings back the Living Fossil, a very old plant, to the Gotham Botanical Garden. She then forces Pamela to help her lead a tour for the Gotham Academy Students. She is also there when Dr. Harleen Quinzel shows up unexpected to speak to Pamela. Then the next morning Luisa is found dead. At first it is deemed an accidental poisoning, but in fact she was poisoned by Grimely because she was getting to close to the fact that he was funneling funds from the Garden’s research to his own illegal pet project.
