La. Civ. Code art. 2315.5
Notwithstanding any other provision of law to the contrary, the surviving spouse, parent, or child of a deceased, who has been convicted of a crime involving the intentional killing or attempted killing of the deceased, or, if not convicted, who has been judicially determined to have participated in the intentional, unjustified killing or attempted killing of the deceased, shall not be entitled to any damages or proceeds in a survival action or an action for wrongful death of the deceased, or to any proceeds distributed in settlement of any such cause of action. In such case, the other child or children of the deceased, or if the deceased left no other child surviving, the other survivors enumerated in the applicable provisions of Articles 2315.1(A) and 2315.2(A), in order of preference stated, may bring a survival action against such surviving spouse, parent, or child, or an action against such surviving spouse, parent, or child for the wrongful death of the deceased.
An executive pardon shall not restore the surviving spouse's, parent's, or child's right to any damages or proceeds in a survival action or an action for wrongful death of the deceased.
