Causing the death of another person without legal justification or excuse. Criminal homicide is a summary category, not a single codified offense. The term, in law, embraces all homicides where the perpetrator intentionally killed someone without legal justification, or accidentally killed someone as a consequence of reckless or grossly negligent conduct. It includes all conduct encompassed by the terms murder, nonnegligent (voluntary) manslaughter, negligent (involuntary) manslaughter, and vehicular manslaughter. The term is broader than the Crime Index category used in the FBI's UCR, in which murder/nonnegligent manslaughter does not include negligent manslaughter or vehicular manslaughter.
