What term is used for the killing of one person by another?

The term "homicide" encompasses a broad range of circumstances where one individual unlawfully kills another. It is the legal term used to define this act, and it includes various categories such as murder, manslaughter, and justifiable homicide. The distinction here is essential; homicide doesn't always imply criminal intent or wrongdoing. For example, some forms of homicide, like justifiable homicide, may occur in self-defense or in defense of others where the act of killing is considered legally permissible.

Understanding this term is critical in law enforcement and criminal justice because it lays the groundwork for categorizing acts of killing based on intent, circumstances, and legal definitions. The other options, such as murder and execution, specify particular aspects of homicide but do not represent the entire scope of the act itself. Thus, "homicide" is the most accurate and inclusive term for the event described.
