I'm at a point in the game where four of the five cases are completed and only the Ice Truck Killer case is active. The next item highlighted is Visit Rita, but the only places available on the GPS are the Police station if I'm at home and home if I'm at the police station. There's no Rita's House or anything like that. I've wandered around both areas looking for something but neither have anyhing important going on at them. Anybody know what I should do?
