Homicide refers to a person taking the life of another human being, regardless of circumstances and encompasses numerous charges including murder. For example, manslaughter or death by auto or vessel are also examples of homicide. According to Cornell Law School, not all homicides result in criminal charges when you can prove that the act is legally justified, such as self-defense.
Murder is the intentional killing of a human being by another person without any legal justification under NJ Rev Stat § 2C:11-3 (2013).
