    Homicide is defined as the killing of one human being by another. Not all forms of homicide are unlawful. First degree murder requires malice aforethought. Malice can be expressed or implied. Felony murder is a criminal homicide that occurs during the commission or attempted commission of a felony. What distinguishes murder from manslaughter is the criminal intent element. Manslaughter is an unlawful killing without malice or murder intent. Gross negligence is the standard to determine manslaughter. Homicide is excusable When committed by accident and misfortune, or in doing any other lawful act by lawful means, with usual and ordinary caution, and without any unlawful intent. It also excusable When committed by accident and misfortune, in the heat of passion, upon any sudden and sufficient provocation, or upon a sudden combat, when no undue advantage is taken, nor any dangerous weapon used, and when the killing is not done in a cruel or unusual manner. Proximate Cause is an event sufficiently related to an injury that the courts deem the event to be the cause of that injury.
