Fortunately, they had already determined that the bullet type was a 9mm handgun cartridge, which narrowed down the type of gun the shooter used.
Jimmy immediately arranged for some agents to search for available surveillance cameras nearby, while also conducting interviews with the neighbors to identify the people in this room.
Back at the FBI office, Jimmy investigated property records from the New York City Hall to identify the landlord's information and directly called them. Unfortunately, the place was rented out, and the landlord confirmed that his family did not live there, although he recalled a name which needed to be verified.
The landlord checked the initial rental contract and found that the tenant's name was false. Jimmy found no corresponding person in the personnel database, and since the rent was paid in cash, there was no bank account information.
