Answer:
People like Escolástica Cisneros, Celeste Dangond, or Yamil did not say anything to Santiago because they did not get any chance to say anything to him he had gone away from the sight.
Explanation:
Chronicle of a Death Foretold is a book written by Gabriel García Márquez. The book is about a foretold murder of Santiago Nasar, the protagonist of the story.
In the novel, everyone in the town knew that Santiago was to be murdered but no one dared to warn him. And those who tried to warn him, it was too late for them.
Escolástica Cisneros, a flower woman saw Santiago and his friend Cristo Bedoya walk in the crowd, but did not warn him because no one dared touch him.
Celeste Dangond did not warn him because he perceived it to be a mere rumour.
Yamil acted once he got to know about the plan but it was too late for him to warn Santiago because he was dead.
