When you enter, you should see three Saints triggers for three wiretap conversations. Enter the building and take the stairs up to the third floor and in the southwestern corner there's a door to the Detective department. This is the same building as the next to last Sons of Samedi mission where you hijack the traffic camera feeds. To get this, first go to the Stilwater Police Deparment in the southern area of the Saints Row district. This one is Vengeance- Exacted Revenge on Julius.
