Wis. Stat. § 767.44: Prohibiting visitation or physical placement if a parent kills other parent.

(1) When prohibited. Notwithstanding ss. 767.225 (1) (am), 767.41 (1), (4), and (5), 767.804 (3) (a), 767.805 (4) (a), and 767.89 (3) and except as provided in sub. (2), in an action under this chapter that affects a minor child, a court may not grant to the child’s parent visitation or physical placement rights with the child if the parent has been convicted under s. 940.01 of the first-degree intentional homicide, or under s. 940.05 of the 2nd-degree intentional homicide, of the child’s other parent, and the conviction has not been reversed, set aside, or vacated.

(2) When not applicable. Subsection (1) does not apply if the court determines by clear and convincing evidence that the visitation or periods of physical placement would be in the best interests of the child. The court shall consider the wishes of the child in making the determination.
