Hotel room

You are another operational group sent to the scene of a crime. The murder took place in a hotel room at 18 Majdanska St. The victim of the murder was an employee of the cleaning service. The previous group, while on the scene, marked some of the traces, inspected the corpse and secured the crime scene. During the course of the activities, it turned out that criminal proceedings had been initiated against one of the police officers who was a member of the group. The group was immediately removed from the case, and the corpse was taken for expert examination. Staff aspirant Jerzy Gruszka - a specialist in serial murders - was seconded to your team from the Police Headquarters in Poznan. This happened because the murder committed in the hotel room is deceptively similar to the murders of several young women in Praga Południe.
