A day before a court in Kolkata is set to deliver its verdict in the RG Kar hospital rape-murder case, the parents of the victim doctor alleged that the investigation is half-done as others involved in the crime are roaming free. Her parents said they will continue to fight until justice is delivered to their daughter whose body was found in the seminar room of the state-run hospital on August 9 last year, sparking nationwide outrage and prolonged protests. Sanjay Roy, who was a civic volunteer with the Kolkata Police, was charged with committing the crime and was arrested on August 10. Additional district and sessions judge of Sealdah court, where the trial of the case concluded on January 9, is scheduled to pass its judgement on Saturday. "Sanjay (Roy) is guilty, and tomorrow's verdict will be against him. But what about other criminals who are still not caught? I can see them roaming freely. I have seen them loitering in the hospital. So, the investigation is half-done," she told
