Involuntary manslaughter usually refers to an unintentional killing that results from recklessness or criminal negligence, or from an unlawful act that is a misdemeanor or low-level felony (such as DUI). The usual distinction from voluntary manslaughter is that involuntary manslaughter (sometimes called “criminally negligent homicide”) is a crime in which the victim’s death is unintended.
For example, Dan comes home to find his wife in bed with Victor. Distraught, Dan heads to a local bar to drown his sorrows. After having five drinks, Dan jumps into his car and drives down the street at twice the posted speed limit, accidentally hitting and killing a pedestrian.
