n United States law, depraved-heart murder, also known as depraved-indifference murder, is an action where a defendant acts with a "depraved indifference" to human life and where such act results in a death. In a depraved-heart murder, defendants commit an act even though they know their act runs an unusually high risk of causing death or serious bodily harm to someone else. If the risk of death or bodily harm is great enough, ignoring it demonstrates a "depraved indifference" to human life and the resulting death is considered to have been committed with malice aforethought. In some states, depraved-heart killings constitute second-degree murder, while in others, the act would be charged with varying degrees of manslaughter.
