This quest is available only after completing the Lady in Trouble quest. You'll find Tim #1 in the church. He will ask you to collect some files from the police station, containing some info on his wife's murder. There is also info about a main suspect inside, whom Tim wants to kill on his own. You'll get to the police station directly from the street #2, so you do not have go through the sewers.
Jump over boxes and barrels on the junction in order to get to the police station entrance #1. You'll find yourself in a garage. Kill all undead and go straight ahead until you reach the door. Go up the stairs (1). Now you have to pass through the entire floor to get to another stairs (2). This time there are undead instead of Punks prowling on the station #2.
Once you get to the upper floor (1), go through the corridor ahead. You'll reach the last room where you can find files. These are on one of the desks in the corner of the room (2). Leave the station and return to the church (you can use Fast Travel option inside the station in the control room). Give Tim the files and collect your reward.
