Book excerpt: Now with SAGE Publishing, The Will to Kill: Making Sense of Senseless Murder explores extraordinary and seemingly inexplicable cases of homicide—not to sensationalize them—but to educate you about these crimes. Authored by renowned experts, the Fifth Edition places recent crimes in context by reviewing current homicide laws, introducing the latest theories that seek to explain murder, and presenting up-to-date statistical data that identify homicide patterns and trends. You will develop a foundational understanding of a variety of topics, for example, domestic and workplace homicide, cult and hate killings, murders committed by juveniles, and serial slayings. You will also examine various criminal justice responses to homicide, including the strategies and tactics employed to apprehend, prosecute, and punish killers. New to the Fifth Edition Up-to-date research and data offers you the latest statistics on homicide patterns and trends in recent years. New illustrative cases cover various forms of homicide, focusing on crimes that drew significant interest from the public and policymakers alike and provide you with unique insights into violent behavior. Updated coverage of recent controversies, legislative changes, and Supreme Court decisions includes heightened concern over mass shootings, hate-motivated homicide and terrorism; new laws, shifting policies, and Supreme Court rulings pertaining to gun rights, juvenile offenders and the death penalty; and advances in surveillance technology, computer-aided investigation, and DNA forensic testing. Early introduction of theories helps you to understand the definition of homicide/homicide laws before developing a theoretical framework to explain violence.
