How did the background of Gabriel Garcia Marquez influence Chronicle of a Death Foretold?

Gabriel Garcia Marquez, author of Chronicle of a Death Foretold, is a Colombian Nobel Prize winner. His most famous novel is One Hundred Years of Solitude. I noticed that he uses the names of several people he knows as the names of characters. I want to know how his experiences and relationships shape the novel in plot development, characterization, theme, and other similar aspects.
