If you are familiar with law enforcement or criminal activity, you have likely heard the term "homicide" at some point. Some people have only a minimal understanding of homicide, with little more than the knowledge that it involves the killing of other people. Of course, nearly everyone is familiar with murder, which also involves the killing of another person. So you may wonder if the two are different ways of saying the same thing, or if they are two different things entirely.
Homicide and murder have similar, yet distinct, legal definitions. Specifically, all murders are homicides, but not all homicides are murders. Murder refers to an instance in which a person knowingly and willfully kills another human being, either with premeditated intent or extreme passion in the moment. Homicide is a much broader term, referring to any instance in which a life was taken due to criminally negligent or reckless behavior.
