Sicilian author and playwright Beatrice Monroy wrote a poem to commemorate the tragedy, "Portella della Ginestra: Indice dei nomi proibiti" (2005). She retells the massacre from the point of view of the victims and their feelings of despair and thirst for justice, as a song of sorrow for the downtrodden of the earth, and as a crime whose instigators are still officially unknown.
