Grandma Vera has 5 granddaughters: Emilia, Luisa, Marilia, Rafaela and Vitoria. One of the granddaughters made a drawing in grandma's Vera wall and now she wants to find the culprit. She asked to her granddaughters and they replied:
Emilia: It wasn't me;
Luisa: The culprit is either Marilia or Rafaela;
Marilia: The culprit is neither Rafaela nor Vitoria;
Rafaela: It wasn't Luisa;
Vitoria: Luisa is lying.
If only one of the 5 granddaughters is lying, who made the drawing in the wall?
This problem is from OBMEP (Brazilian Math Olympiad) 2018.
