The book "I Am a Killer: What Makes a Murderer" is a collection of true stories told by convicted murderers, offering a unique perspective on the motivations and thought processes behind their actions. Through in-depth interviews with the prisoners, the authors gain insight into the minds of those who have taken lives, exploring the complex web of circumstances that led them down this path. The book delves into the personal histories, emotions, and experiences that shaped these individuals, providing a nuanced understanding of the human side of murder. The book begins with an introduction to the creators of Netflix's I Am a Killer, who embarked on a journey to understand the killers' perspectives through unprecedented access to high-security prisons across the country. This allows for a comprehensive examination of the factors contributing to violent crimes, as seen through the eyes of both the perpetrators and their families, law enforcement officials, and victims' relatives. Each profile features exclusive photographs, documents, and commentary from the documentary producers to provide a balanced account of the crime. The first story is about John Giuca, who was sentenced to death for killing his wife and her lover. He describes how he struggled with drug addiction and mental health issues throughout his life, leading him to commit such a heinous act. He expresses remorse for his actions and acknowledges the pain he inflicted on his family and the community.
