Homicide from WikiPedia:

Homicide (Latin homicidium, homo human being + caedere to cut, kill) refers to the act of killing another human being. It can also describe a person who has committed such an act, though this use is rare in modern English. Homicide is not always an illegal act, so although "homicide" is often used as a synonym for "murder," this is not formally correct.

Homicides do not always involve a crime. Sometimes the law allows homicide by allowing certain defenses to criminal charges. One of the most recognized is self defense, which provides that a person is entitled to commit homicide to protect his or her own life from a deadly attack.
