(A) A court may do one of the following with respect to a parent convicted of killing the other parent of a child if the court determines, by clear and convincing evidence, that it is in the best interest of the child and the child consents:
1. (1) Issue a custody order designating the parent as the residential parent and legal custodian of the child or granting custody of the child to that parent;
2. (2) Issue a visitation order granting that parent visitation rights with the child.
