While under the thrall of the drug Vero, she appeared to die of a heart attack. Further analysis revealed that she was killed by the drug in a deliberate overdose.
The motive for her and Scarlett Davis' simultaneous murder was that the mother of Lila Hoving, Mrs. Hoving, believed that the girls were responsible for Lila's drowning. It was eventually revealed that Lila had committed suicide after taking Vero. Lila was a 'natural' and the drug was specifically designed for Chromes and Lila was shown how limited she was by taking it.
