If you have been charged with this crime, do not speak to the police and do not delay!
Black's Law Dictionary defines manslaughter as an unlawful killing of another person without malice aforethought. The crime of manslaughter was developed as an alternative to murder and its attendant death penalty for homicides that were not as extreme and that were explainable. Most jurisdictions distinguish between voluntary and involuntary manslaughter. In general, voluntary manslaughter is an intentional killing commited under circumstances that mitigate the homicide, although they do not justify it.
Involuntary manslaughter consists of "criminally negligent homicide" and "unlawful act manslaughter". A typical example of criminally negligent homicide is where a death results from the negligent operation of an automobile. The standard form of the offense exists where the defendant has killed someone as the consequence of his or her gross negligence or recklessness. Unlawful act manslaughter occurs when someone dies as the result of the defendant doing an unlawful act, usually a misdemeanor.
Voluntary manslaughter is a murder that is reduced in degree by the presence of provocation that caused the murder to be committed in the heat of passion. People v Townes 391 Mich 578 (1974)
