Why did Capote split the narrative into four sections IN cold blood?

Capote divided "In Cold Blood" into four sections to provide a structured exploration of the events surrounding the Clutter family’s murder, the investigation, and the subsequent trial. This segmentation allows readers to delve deeply into the lives of both the victims and the perpetrators, highlighting the contrasts between them. It also emphasizes the complexity of the crime and its repercussions on the community, creating a more nuanced understanding of the human condition in the face of violence. Ultimately, this structure enhances the narrative’s tension and emotional impact.
