HOMICIDE
Homicide is the killing of one human being taking away the life of another human being by act, procurement, or omission. Homicide is not necessarily a crime unless it is criminal homicide.
A person is guilty of criminal homicide if he purposely, knowingly, intentionally, recklessly, or negligently causes the death of another person without lawful excuse or justification.
In California criminal homicide (unlawful homicide) is broken into different categories.
