This walkthrough is freakin awful. It's more like a synopsis of the story. Doesn't help me solve cases at all.

Upon Reflection
The Patrol Desk serves as a tutorial to the game. These first four cases are rather short compared to bigger cases that come along. Your partner for this desk is officer Ralph Dunn.
You'll be looking at the murder scene of one Mr. Rose. You can examine the blood stains, but the main objective is to find the murder weapon. Swing around to the left side of the alley to discover a drain pipe. Climb this pipe and you'll land on the roof. Just a few steps away is the murder weapon, a revolver with serial number and all.

Talk to Dunn and he'll inform you of a gun store nearby. Get back into your squad car and visit this store. The shop owner will know the gun, and give you the registry to cross check the serial number. You'll learn that the gun belongs to a man named Schroeder who knew Rose; the gun registry also has his home address.

Ride to Schroder's apartment and inspect the mail boxes to find his room. Bust into his place and he will sock Dunn cold. Take down the suspect in a fist fight and examine his dresser drawer to find a notebook with Rose's name. Dunn will tell you to leave it, ending the case.
