Louisiana Revised Statutes Tit. 14, § 31. Manslaughter

(1) A homicide which would be murder under either Article 30 (first degree murder) or Article 30.1 (second degree murder), but the offense is committed in sudden passion or heat of blood immediately caused by provocation sufficient to deprive an average person of his self-control and cool reflection. Provocation shall not reduce a homicide to manslaughter if the jury finds that the offender's blood had actually cooled, or that an average person's blood would have cooled, at the time the offense was committed; or

(2) A homicide committed, without any intent to cause death or great bodily harm.

(3) When the offender commits or attempts to commit any crime of violence as defined by R.S. 14:2(B), which is part of a continuous sequence of events resulting in the death of a human being where it was foreseeable that the offender's conduct during the commission of the crime could result in death or great bodily harm to a human being, even if the offender has no intent to kill or to inflict great bodily harm. For purposes of this Paragraph, it shall be immaterial whether or not the person who performed the direct act resulting in the death was acting in concert with the offender.
